Do I need a Micro filter?

Micro filters are used to prevent common telephone equipment, such as phones, answering machines and fax machines, from interfering with your ADSL service. If your ADSL enabled phone line is being used with any other equipment other than your ADSL Modem then you will need to use one Micro filter for each phone device.

Splitters may be installed when your ADSL line is installed or when your current phone line is upgraded to ADSL. If your telephone line is already split you will not need to use a Microfilter

Overview

- check with your ADSL service provider if you are unsure. Each micro filter is connected in-line with your telephone or fax machine so that all signals pass

through it. T elephones and/or facsimiles in other rooms that are using the same extension will also require Microfilters. The following diagram gives an example of connecting your ADSL Modem/Router using a Microfilter.

A suitable Microfilter can be purchased from NetComm or your Service Provider, if required.

Step 3: Configuring your Computer to use the NB1300Plus4 Wireless

To use the NB1300Plus4 Wireless ADSL Modem to access the Internet, your computer must have an IP Address that is in the same LAN subnet as the NB1300Plus4 Wireless ADSL Router and use the NB1300Plus4 Wireless ADSL Router’s IP address as its gateway. The easiest way to do this is to ensure that your computer is set to use DHCP, and all of the required configuration will be performed by the NB1300Plus4 Wireless.

Most applications call for the Primary and Secondary DNS server entries to be made on each computer. These can be automatically assigned by another DHCP server or by enabling the DHCP server on the NB1300Plus4 Wireless ADSL Modem, and entering the DNS values in the DNS section of the NB1300Plus4 Wireless.

The following example shows how a computer could be set up when the NB1300Plus4 Wireless ADSL Modem is configured with no DHCP service for this example. The NB1300Plus4 Wireless ADSL Modem would be set to a LAN IP Address (Gateway) of 192.168.1.1 with a Subnet Mask of 255.255.255.0

Setting up your Wireless LAN

Introduction to Setting up your WLAN

The IEEE 802.11b standard is the most widely used standard for wireless LANs today. A wireless LAN (WLAN) is a wireless computer network that transmits data using radio signals instead of cables. WLAN technology is commonly used in home, small office and large corporate networks. WLAN devices have a high degree of mobility and flexibility that allow networks to be quickly set up or dismantled and allow them to roam freely throughout the network.

Wireless LAN users can use the same network applications used on an Ethernet LAN. 802.11b adapter cards used on laptop and desktop computers support the same protocols as Ethernet adapter cards. For most users, there is no functional difference between computers attached to a wired Ethernet LAN or a mobile 802.11b workstation except that hardware is not physically attached to the network. For most networks however, it may be desirable for mobile network devices to be able to link to the wired Ethernet LAN to use shared resources such as servers, printers or an Internet connection. This product unites Ethernet and 802.11b/g wireless private networks with an Internet connection. The Wireless USB 2.0 Network Adapter supports data rates of up to 54 Mbps for wireless operation when used in conjunction with other IEEE 802.11 b/g compatible devices.

WLAN technology provides users with many convenient and cost saving features:

Mobility: WLAN provide LAN users with access to real-time

information anywhere in their organization, without being limited to the wired connection.

Easy Installation: Installing this device is easy for novice and expert

users alike, eliminating the need for network cables in walls and ceilings.

Wireless

Scalab ili ty : WLAN can be configured in a variety of topologies

to adapt to specific applications and installations. Configurations are easily changed and range from peer-to-peer networks suitable for a small number of users, to full infrastructure networks of thousands of users roaming over an extensive area.

WLAN Basic Information

Some basic understanding of 802.11b/g wireless technology and terminology is useful when you are setting up the router or any wireless access point. If you are not familiar with wireless networks please take a few minutes to learn the basics.

www.netcomm.com.au Rev. 1- YML709 Page 38 NB1300Plus4 ADSL Modem

Transmitting Radio Signals

WLAN devices use electromagnetic waves within a broad, unlicensed range of the radio spectrum to transmit and receive radio signals. When a wireless access point is present, it becomes a base for other WLAN devices in its broadcast range. WLAN nodes transmit digital data using FM (frequency modulation) radio signals. WLAN devices generate a carrier wave and modulate this signal using various techniques. In this way, digital data can then be superimposed onto the carrier signal. This radio signal carries data to WLAN devices within range of the transmitting device. The antennae of WLAN devices listen for and receive the signal, which in turn is then altered and the transmitted data extracted and sent to your computer.

Range

Range should not be a problem in most homes or small offices. If you experience low or no signal strength in some areas, consider positioning the device in a location between the WLAN devices maintaining a roughly equal straight-line distance to all devices that need to access the Router through the wireless interface. Adding more 802.11b/g W ireless Network Adapters to rooms where the signal is weak can improve signal strength.

Wireless LAN Modes

Wireless LANs can be configured in one of two ways:

Ad-hoc Networking Also known as a peer-to-peer network, an ad-hoc

network is one that allows all workstations and computers in the network to act as servers to all other users on the network. Users on the network can share files, print to a shared printer, and access the Internet with a shared modem. However, with adhoc networking, users can only communicate with other wireless LAN computers that are in the wireless LAN workgroup, and are within range.

Wireless

Infrastructure Networking Infrastructure networking differs from ad-hoc

networking in that it includes an access point. Unlike the ad-hoc structure where users on the LAN contend the shared bandwidth, on an infrastructure network the access point can manage the bandwidth to maximize bandwidth utilization.

Additionally, the access point enables users on a wireless LAN to access an existing wired network, allowing wireless users to take advantage of the wired networks resources, such as Internet, email, file transfer, and printer sharing.

Infrastructure networking has the following advantages over ad-hoc networking:

■ Extended range: each wireless LAN computer within the range of the access point can

communicate with other wireless LAN computers within range of the access point.

Rev. 1 - YML709 www.netcomm.com.au NB1300Plus4 Wireless ADSL Modem Page 39

■ Roaming: the access point enables a wireless LAN computer to move through a building and

still be connected to the LAN.

■ Wired to wireless LAN connectivity: the access point bridges the gap between wireless

LANs and their wired counterparts.

Planning a Wireless Network

Infrastructure or Adhoc mode

Use Adhoc mode if you wish to join several wireless clients to each other in a small area and you do not need these devices to access your Internet connection or other “wired services”. Remember if you include a Wireless Access Point (AP) in your network you must use Infrastructure mode to work with it.

When connecting to an Adhoc network you must know the following parameters in order to configure your Client Adapter correctly to join the Adhoc network;

■ Network Name (SSID)

■ Network Channel

■ Encryption type (none, 64bit WEP, 128bit WEP, WPA)

■ Encryption keys (only if encryption is enabled)

Example of Adhoc Networking

Client Adapter 1 Mode = Adhoc SSID = “Hyperion” Channel = 5

Client Adapter 2 Mode = Adhoc SSID = “Hyperion” Channel = 5

Wireless

Client Adapter 3 Mode = Adhoc SSID = “Hyperion” Channel = 5

Use Infrastructure mode if you wish to join several wireless clients together over a wider area as well as offer them access to “wired services” (such as a LAN with Network printers or Servers). An Infrastructure requires the use of one or more Access Points (AP’s) to be installed. NetComm Wireless Routers operate as Access Points and are a great way of sharing your Internet connection wirelessly.

Note: Access Points can only operate in Infrastructure mode. Adhoc networks are often

temporarily setup between two or more Wireless clients to share files at a conference etc.

www.netcomm.com.au Rev. 1- YML709 Page 40 NB1300Plus4 ADSL Modem

When connecting to an Infrastructure network you must know the following parameters in order to configure your Client Adapter correctly to join the Infrastructure network;

■ Network Name (SSID)

■ Encryption type (none, 64bit WEP, 128bit WEP, WPA)

■ Encryption keys (only if encryption is enabled)

Example of Infrastructure Networking

Access Point 1 SSID = “Kelewan” Channel = 1

Client Adapter 4 Mode = Infrastructure SSID = “Kelewan”

Client Adapter 5 Mode = Infrastructure SSID = “Kelewan”

Access Point 2 SSID = “Kelewan” Channel = 12

Client Adapter 6 Mode = Infrastructure SSID = “Kelewan”

Client Adapter 7 Mode = Infrastructure SSID = “Kelewan”

Client Adapter 8 Mode = Infrastructure SSID = “Kelewan”

Positioning of AP & Client Adapters

Generally Adhoc networks work across shorter ranges than Infrastructure networks because there is no Access point (which naturally acts as a repeater station – extending range). Both types of Wireless LANs (WLAN’s) work best when the signal is unobstructed by metal or other thick structures containing metal. When positioning Wireless devices remember the following guide lines;

Wireless

■ Access Points should be located in the center of their intended coverage area

■ An AP with an Omni antenna transmits in a 3 dimensional sphere out from the antenna

■ Where possible the AP should be placed in the ceiling, this gives best overall range because it

reduces obstructions.

■ A wall that is 30cm thick becomes 42cm thick on a 45 degree diagonal. Therefore the signal

will be depleted even more when the direct line of sight between two Wireless devices passes diagonally through an interfering wall.

■ Avoid placing AP or Client Adapters near strong interference created by other devices such

as cordless phones, microwaves etc.

■ Perform a full site survey at the four corners on the fringe of your network to determine if

there are any other wireless networks present and what channels they are using.

■ Avoid using Channels that are adjacent to one another (e.g. Use Channels 1, 6 & 13 when

using three AP’s in the same area)

Rev. 1 - YML709 www.netcomm.com.au NB1300Plus4 Wireless ADSL Modem Page 41

■ For maximum range keep AP’s and Client Adapters away from metal structures or

conductive materials (such as people, cubicle framing, window frames, computers, lights, phones, speakers)

Channels, SSID & Roaming

In an Adhoc Network each device must be told what channel to use in addition to the Network name (SSID). Infrastructure mode works differently because the access point tells the Client Adapter what channel to use, all the Client adapter needs to know to find the network is the SSID.

When you first setup your Wireless network you should perform a site survey using the NetComm Wireless utility that comes with your Client Adapter. When you know what channels are currently being used make a list of the Channels that are not being used and choose a channel that is the most numerically distant from the all of the ‘used’ channels.

Then choose a Network name (SSID) that is suitable to identify your wireless network.

Note: For security it is best not to use an SSID that describes; You, Your Wireless

Product, Your Company, Your location or the services available.

Roaming is a way of running an Infrastructure Wireless Network in an area that needs more than one AP to obtain complete coverage. Roaming works by using the same SSID for each access point but by placing them on different channels and with their fringe radio coverage slightly overlapping. When a Client adapter comes into range of an AP with the correct SSID it will associate with the AP and join the network, if the Client Adapter moves out of range of the first AP and into range of another AP (with the same SSID) then the Client Adapter will change channel to suit the new AP and maintain connection to the same Wireless network.

Wireless Encryption & Security

Adhoc networks and Infrastructure networks can both use Wireless encryption to keep their data secure and prevent unauthorised associations. Infrastructure networks also have a few extra

Wireless

security measures that allow you to make your wireless network more secure than an Adhoc network The most common Wireless Network Security features are;

■ Effective range / Radio partitioning

■ SSID

■ Broadcast Beacon Disabling

■ MAC address filtering

■ Encryption (WEP, WPA-Psk)

■ Third party Authentication (WPA-Radius / 802.11i / 802.11x EAP TLS Certificates etc)

www.netcomm.com.au Rev. 1- YML709 Page 42 NB1300Plus4 ADSL Modem

Effective Range

When planning your wireless network it is best to position your Access Points and Client Adapters away from the perimeter of your property where possible. Obviously the first goal is to ensure reception to all areas but remember that the more your wireless emissions leak outside the property the more likely unauthorised access can be obtained without entering the property.

SSID

The SSID is in a way a simplified security, although it may be easily found by a site survey but whoever finds it may not know who it belongs to. Best practice is to keep it secret where possible and ensure it does not describe You, Your Wireless Product, Your Company, Your location or the services available.

Broadcast Beacon Disabling

Some Access Points allow you to disable the Broadcast Beacon to make the Wireless Network harder to find. However this does hide the network more from the ‘casual browser’ it is not a way of protecting your data as it travels in the air or a way of preventing unauthorised access.

MAC Address Filtering

In most Access Points it is possible to only allow Wireless Clients with known MAC addresses to associate with the Access Point. Your Access Point will maintain an “Authorised MAC Address table” where you must enter the MAC address of each Wireless Client Adapter you want to allow to access the AP.

MAC address filtering does not prevent unauthorised interception of your data as it travels through the air. MAC addresses can also be intercepted and cloned (or spoofed) so that an unauthorised Wireless Client Adapter could be made to pretend to be an authorised Client Adapter and gain access to the network. MAC filtering has the advantage of not adding any overheads to the packet and therefore maintains maximum throughput.

Wireless

Encryption

Wired Equivalent Privacy (WEP) is available in 64 bit and 128 bit standards and is configured using a key of Hexadecimal characters to encrypt your data before it is transmitted. This maintains the integrity and privacy of your data, however your WEP key can be determined if enough data is ‘sniffed’ as it passes between Access Point and Client adapters. Because the WEP key is common to every Client adapter on the network it is also necessary to change the keys in every client adapter in order to recover from a stolen key situation.

WiFi Protected Access (WPA) builds upon the WEP method but has two alternate methods these are;

■ WPA – PSK

■ WPA – RADIUS

Rev. 1 - YML709 www.netcomm.com.au NB1300Plus4 Wireless ADSL Modem Page 43

WPA – PSK uses a Pre-Shared Key similar to WEP but it has an improved system that prevents the keys from being determined by ‘sniffing’. WPA – PSK offers the small scale simplicity of WEP but with increased security that prevents ‘Key cracking’

WPA – RADIUS uses a RADIUS server to provide centralised and a per client key management system. Because RADIUS servers are already used in large scale networks it provides a scalable and manageable solution to large companies.

Both forms of WPA will prevent your data being readable if it is intercepted by ‘sniffing’ and it will prevent unauthorised associations on your wireless network.

Third party Authentication 802.11x / 802.11i

These are standards and draft standards often used similar to WPA that incorporate alternative methods of authentication including Certificates and Biotechnologies (such as thumb printing etc).

Configuring Client Adapters

Mode (Adhoc or Infrastructure)

When configuring your Wireless Client adapter you must first determine if you are connecting to an Adhoc Network or an Infrastructure network. Choose the appropriate mode for your network and apply the changes.

SSID

In Adhoc mode or Infrastructure mode set this to be the same for every Client Adapter (and matching the AP if in Infrastructure mode).

Note: Most Client adapters allow you to set the SSID as “ANY”, which tells the Client

Adapter to associate with the first wireless network it finds, regardless of the SSID.

Channel

Wireless

The Channel does not need to be specified when using Infrastructure mode as it will change to suit the access point. In Adhoc mode you must ensure that all Client Adapters you want to join the network are configured to use the same channel.

Encryption

When using WEP the Keys should be common to all Client adapters and Access Points, you must also specify which key (1, 2, 3 or 4) is currently being used.

If using other Encryption such as WPA – PSK you should ensure that encryption is setup correctly between your AP and Client Adapters.

WPA – RADIUS this encryption is too complicated to explain here but if compulsory to join the network it must be configured correctly before you can associate with the network.

www.netcomm.com.au Rev. 1- YML709 Page 44 NB1300Plus4 ADSL Modem

Note: If a Wireless Network has encryption enabled you will not be assigned an IP

address or be able to associate with the Network until you have encryption configured correctly.

IP Addresses

It is important to note that Wireless Networks operate similar to Wired Networks. Usually Broadcast protocols such as DHCP will work across them seamlessly; therefore if you have a DHCP server available on your network it should be able to dynamically assign an IP address to any clients. Your IP address setting should be considered closely if you are running an Adhoc network because you are less likely to be running a DHCP server.

Windows defaults for DHCP clients usually fall back to the Automatic Private IP Address (APIPA) scheme when no DHCP server is available, this means that your Adhoc devices will end up with an IP address in the range 169.xxx.xxx.xxx. This is fine for setting up a temporary network but for something more permanent you may wish to assign static IP addresses to each client device.

File Sharing over Wireless

Once you have your Wireless device connected you may wish to access to files on a server or another Client. This can be done in several ways depending on your Network operating system and architecture. The simplest example for Windows users is to use ‘mapped network drives’ remember to do this you must either map the drive via an IP address (e.g. \\10.0.2.10\sharename) or use full UNC path names to your network drives.

Network Printing, Email and Web browsing over Wireless

All these services should work automatically over your wireless network the same as if you were connected to the wired network. If these services are not working you should check that you can ping via your wireless network and that the IP Address, Subnet mask and Gateway are correct for your wireless network (generally the same as for the wired network).

Configuring the Firewall

The NB1300Plus4W has an inbuilt firewall. A firewall is a device which prevents unauthorized users from gaining access to your computer network. This tutorial will show you how to configure the advanced options of this firewall. Configuration of these options is only recommended for advanced users. The NB1300plus4W defaults include a moderate level of security and usually the firewall will only require further configuration if a higher or lower security level is required.

Note: You can click on the Firewall link at the top of the page to return to the main firewall

configuration screen at any time.

Protection Policy - allows you to enable the firewall to check for different types of unauthorized access - when you've finished with this page, click on Submit.

Hacker Log - allows you to manage logging preferences for the firewall. Syslog event - section allows you to determine which events are logged. Syslog Operation - section allows you to determine the properties of the log, and where you

want to send the logs to. You can send them via email, or you can send them to a computer on your LAN. Note that if you choose to send the logs to a computer on your LAN, that computer must be running a suitable Syslog application.

When you've finished configuring these options, click on "submit".

Service Filtering

The service filtering setting allows you to filter incoming connections from your external network. Checking the box will block incoming traffic for that protocol. When you've finished, click on Submit to save the settings.

Remember if you've changed any settings, you must save them to flash by clicking on Save Firewall Configuration at the bottom of the Firewall Configuration screen. Then you'll need to press Save Settings and Reboot on the side menu, then clicking "Save & Reboot" in the next page displayed.

Configuring Groups

The NB1300Plus4W's inbuilt firewall works by using groups and policies. Groups are used to define certain settings. These settings are used when creating firewall rules, or policies.

Firewall Databases

The IP Group section allows you to add IP address information to the group database. You can add a single IP , an IP range and a Subnet range. In this example, we are adding an IP entry named "mailserver" with an IP address of 192.168.1.137. Note that if you are adding single IPs, it must be entered in both the IP address 1 and 2 fields. Click on Add/Modify to add the entry to the database.

Once you've finished adding or modifying entries to this section, click on the firewall link at the top of the screen to return to the main firewall configuration screen.

The Service Group is used to set port information to the group database. As you can see, the most common ports have already been entered into the database. To add new entries, simply enter their relevant details into the input fields near the bottom of the screen. In this example, we are adding a "PPTP" port, which uses the TCP protcol and port number 1723. You'll need to click on the Add/Modify button to add it to the database.

The Time Window Group allows you to create periods of time which can be used in a firewall policy. To add a new entry, simply give it a name and then specify the time period using the drop down box. In this example, we are creating an entry called "Monday9to5" which is the time period of 9am to 5pm on Monday.

The FTP Group is a pre-defined group used to filter certain FTP commands. The example shown is an entry called DenyMKD, where the MKD command is selected, and the action is set to deny. Also, make sure you click on the "Add modify entry" button to save the entry to the group database.

The SMTP Group pre-defined group used to filter certain SMTP commands. In this example, we are creating an entry called "allow all" which has all the commands selected and the action is set to allow. You'll need to click on "Add modify entry" button to save the entry.

The HTTP group allows you to block either URLs, keywords in a URL or certain special applications in that URL. In this example, we are creating a "DenyYahoo" entry, which will block access to the www.yahoo.com.au website.

Remember if you've added or changed any entries, you must save them to flash by clicking on Save Firewall Configuration at the bottom of the Firewall Configuration screen. Then you'll need to press Save Settings and Reboot on the side menu, then clicking "Save & Reboot".

Security

Configuring Policies

Once you've created entries in the NB1300Plus4W's group databases, it is time to create a policy. A policy is a firewall rule which governs data passing through the firewall. You can create an inbound policy - a policy for data coming in from the internet or an outbound policy which is a policy for data going out to the internet.

To create an inbound policy, click on the inbound policy link under the "Inbound /Outbound policies" heading. You will now be presented with an Adding New Policy screen.

Firstly, you can specify whether the rule applies to a certain IP, IP range or any IP. You can also specify a range created in the IP Group if you've done so by using the "DB" drop down box. This must be done for both the Source IP and the Destination IP,

Secondly you can specify which ports this rule applies to. You can either specify the ports manually, or use a group database rule if you've created one previously.

Now, select the Transport Protocol, which can be TCP, UDP or both. You can also enable reverse NAT if you wish. Also select whether this rule applies an Allow or Deny action.

The next sections (Time window, ftp content, SMTP content, http content) refer directly to group databases. If you haven't created any rules under the relevant group database, you will not be able to use these sections. Select the relevant rules using the drop down box.

Once you've finished click on "Add Modify inbound policy" to add the rule to the database. You should now see it listed under the Inbound Policy screen. To create more rules, you will need to click on the "Add" button.

The Outbound Policy screen is essentially the same, other than it deals with outgoing connections rather than incoming connections. You can modify policies in either screen by clicking on "edit" for the rule you wish to modify.

Remember if you've added changed any entries, you must save them to flash by clicking on Save Firewall Configuration at the bottom of the Firewall Configuration screen. Then you'll need to press Save Settings and Reboot on the side menu, then clicking "Save & Reboot".

Advanced Configuration for your NB1300Plus4 Wireless

How to make changes

The NB1300Plus4 Wireless utilises a Web based interface for configuration, this means that you do not need to load drivers (unless using USB) and configuration is always performed via a W eb browser (such as Internet Explorer or Netscape Navigator).

For each configuration page there is a Submit button to store the changes for that page before you move on to the next page. Once you have made and submitted all your required changes you must click the Save Settings and Reboot button.

Clicking this button will permanently store all your changes and implement them by performing a reboot. Please wait up to 30 seconds for your router to reboot and resynchronize the ADSL link (Showtime). The Reboot process is complete when the RDY light starts pulsing steadily again.

Note: DO NOT power the unit off or press the reset button again during the reboot process

Multiple Virtual Circuits

The NB1300Plus4 Wireless is capable of being configured to maintain multiple virtual circuits – that is multiple routed connections or PPP sessions down the same ADSL copper cable. Most ADSL connections will only support one PPP session please confirm your line’s / accounts capabilities with your ISP. All configurations made in the one-page setup are made to Virtual Circuit Zero (VC0). You can configure the other VCs individually by opening the Advanced WAN page and selecting which VC you want to edit at the bottom of the page then pressing the Submit button. All fields on that page will be presented in terms of the Virtual Circuit number just chosen.

USB or Ethernet?

The NB1300Plus4 Wireless can be connected via a USB cable or an Ethernet cable or both. The reason for this is that the USB connection is simply an ethernet simulation, as far as your computer is concerned the USB connection is an Ethernet connection, hence DHCP and other protocols will work the same as for Ethernet.

1. After connecting all the ADSL Router cables,

powering on the ADSL Router , and launching a web browser, such as Internet Explorer or Netscape Navigator, browse to the address http://192.168.1.1.

2. Enter the correct user name and password to access

the Configuration tool. The default user name and password are as below.

PPP: The current release supports multiple PPP sessions per PVC. The PPP configuration in the WAN configuration page is for the first PPP session for each PVC. The predefined PPP Account Name (Account ID) is "Simple PPP Account 0" for PVC0 and predefined PPP Connection Name is "Simple PPP Session 0" for PVC0. For the other PVC X, the predefined account name and connection name will be Simple PPP Account X and Simple PPP Session X. X is the PVC number from 1 to 7.

It can support up to total of 16 PPP sessions, and each PVC can support up to 8 PPP sessions. The multiple PPP sessions may be configured with any combination over 8 PVCs.

For the multiple PPP sessions, please go to PPP Configuration page (Section 6.3). Service Name: The service name of PPP is required by some ISPs. If the ISP does not

provide the Service Name, please leave it blank. Disconnect Timeout: The Disconnect Timeout allows the user to set the specific period of

time to disconnect from the ISP. The default is 0, which means never disconnect from the ISP.

DHCP Client: Use Table 6-1 to configure a valid setting for each PVC. MRU: Maximum Receive Unit indicates the peer of PPP connection the maximum size of

the PPP information field this device can be received. The default value is 1492 and is used in the beginning of the PPP negotiation. In the normal negotiation, the peer will accept this

Advanced

MRU and will not send packet with information field larger than this value.

www.netcomm.com.au Rev. 1- YML709 Page 58 NB1300Plus4 ADSL Modem

MTU: Maximum Transmission Unit indicates the network stack of any packet is larger than this value will be fragmented before the transmission. During the PPP negotiation, the peer of the PPP connection will indicates its MRU and will be accepted. The actual MTU of the PPP connection will be set to the smaller one of MTU and the peer's MRU. The default is value 1492.

MSS: Maximum Segment Size is the largest size of data that TCP will send in a single IP packet. When a connection is established between a LAN client and a host in the WAN side, the LAN client and the WAN host will indicate their MSS during the TCP connection handshake. The default value is 1432.

Automatic Reconnect: When it is checked, it will maintain the PPP connection all the time. If the ISP shut down the PPP connection, it will automatically reconnect PPP session.

Authentication: When AUTO option is chosen, the PAP mode will run first then CHAP. If you are having connection problems with PPPoA or PPPoE connections it is recommended that you try forcing either PAP or CHAP modes.

Host name: Required by some ISPs. If the ISP does not provide the Host name, please leave it blank.

Q1: If the PPP is disconnected after the Disconnect Timeout and how can I reconnect it?

A: You have to go to the PPP Status under Admin Privileged column, choose the correct PVC and Connect option, and then click Execute to restart a new PPP secession. Alternatively you can click the CONNECT button at the bottom of the OnePage setup.

When should I change my MTU settings?

MTU settings should be changed to suit your ISPs recommendations if you are experiencing the following symptoms;

■ General emails send but emails with attachments fail

■ Can achieve a connection but some web pages wont load or can't download files.

■ Windows Update starts but fails to complete.

■ Y our ISP recommends you change the setting.

What should I change my MTU settings to?

MTU settings should be set to 1492 to start with, if you still have problems try lowering them to 1456, 1400 or even as low as 750 to see if the problem improves. Your ISP is the best person to contact to find out what MTU setting to use.

Note: MTU above 1492 is likely to cause problems and is not likely to improve data

throughput.

DNS

The DNS Configuration page allows you to set the configuration of DNS proxy. The NetComm firmware supports DNS proxy. For the DHCP requests from local PCs, the

DHCP server will set the LAN port IP as the default DNS server. Thus, all DNS query messages will come into LAN port first. The DNS proxy on the ADSL modem recorded the available DNS servers, and forward DNS query messages to one of DNS server.

Disable DNS Proxy: The LAN port does not process the DNS query message. For the DHCP requests from local PCs, the DHCP server will set the user-configured preferred DNS sever or alternate DNS server whichever is available as the DNS server. Then all DNS query messages will be directly sent to the DNS servers.

Use Auto Discovered DNS Servers Only: The DNS proxy will store the DNS server IP addresses obtained from DHCP client or PPP into the table. And all DNS query messages will be sent to one of the dynamically obtained DNS servers.

Use User Configured DNS Servers Only: The DNS proxy will use the user-configured preferred DNS server and alternate DNS server. And all DNS query message will be sent to one of DNS servers. Enter the DNS IP in the Preferred DNS Server and Alternate DNS Server fields.

Auto Discovery + User Configured: The DNS proxy's table has all the IP addresses of dynamically obtained and user configured DNS servers.

PPP Half Bridge: When the PPP Half Bridge is enabled, only one PC is able to access the Internet, and the DHCP server will duplicate the WAN IP address from the ISP to the local client PC. Only the PC with the WAN IP address can access the Internet. This function should only be used if one computer will be allowed to connect to the internet (E.G a Software firewall computer or Proxy server)

Q: What is the difference between PPP connect on WAN access and the Automatic Reconnect?

A: Some ISPs terminated the PPP session due to the inactivity. For the PPP connect on WAN access, the PPP will be automatically reconnected when an URL is entered in the browser (packet interested in going out the WAN). For the Automatic Reconnect, it will reconnect the PPP session whenever it is terminated by ISP.

Appendix B - T rouble Shooting

The following section gives details about troubleshooting issues for your NB1300Plus4 Wireless ADSL Modem. Problems are divided into different areas to assist you in finding the appropriate solution.

General Modem Operation

Before continuing, refer to the correct power up sequence to verify that your NB1300Plus4 Wireless ADSL Modem is operating.

Correct power up sequence

After you turn on your NB1300Plus4 Wireless ADSL Modem, the following sequence should occur:

1. When power is first applied, verify that both the Power LED and Ready LED are on.

2. The RDY LED will turn off after 5 seconds.

3. After approximately 10 seconds, verify that:

■ The RDY LED will flash which indicates that the modem is ready for use.

■ The LAN LED will only light when a ethernet cable is connected and a successful LAN

connection is made.

If any of these conditions does not occur, refer to the appropriate section below.

PWR LED Not On

If the PWR and other LEDs are off when your ADSL modem is turned on:

■ Make sure that the power cord is properly connected to your ADSL Modem and that the

power supply adapter is also properly connected to a functioning power outlet.

■ Check that you are using the 12 V AC power adapter supplied by NetComm for this

product.

If the error persists, you have a hardware problem and should contact NetComm technical support.

Resetting the NB1300Plus4 Wireless ADSL Modem

To restore the factory default configuration settings without knowing the administration password or IP address, you must use the Default Reset button on the rear panel of the ADSL Modem.

1. Press and hold the Default Reset button for about 10 seconds.

2. Release the Default Reset button and wait for the Modem to reboot (which will take approximately one minute).

www.netcomm.com.au Rev. 1- YML709 Page 92 NB1300Plus4 ADSL Modem

Web Based Interface

If you are unable to access the NB1300Plus4 Wireless ADSL Modem’s Web Based Interface from a computer on your local network, check the following:

■ Check the Ethernet connection between your computer and your NetComm ADSL Modem.

■ Make sure your computer’s IP address is on the same subnet as your ADSL Modem. If you

are using the recommended addressing scheme, your computer’s address should be in the range of 192.168.1.1 to 192.168.1.254.

Note: If your computer’s IP address is shown as 169.254.x.x: Recent versions of

Windows and MacOS will generate and assign an IP address if the computer cannot reach a DHCP server. These auto-generated addresses are in the range of

169.254.x.x. If your IP address is in this range, check the connection from the computer to your ADSL Modem and reboot your computer.

■ If your ADSL Modem’s IP address has been changed and you don’t know the current IP

address, reset your ADSL Modem’s configuration to factory defaults. This will set the ADSL Modem’s IP address to 192.168.1.1.

■ Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet

Explorer, click Refresh to be sure the Java applet is loaded.

■ Try quitting the browser and launching it again.

■ Make sure you are using the correct login information. The factory default login name is

admin and the password is password. Make sure that Caps Lock is off when entering this information.

If your ADSL Modem does not save changes you have made in the Web Based Interface, check the following:

■ When entering configuration settings, be sure to click the Submit button before moving to

another menu or tab, or else your changes will be lost.

■ Once all of the changes are made, click the save settings button to save your settings. The

unit will then automatically reboot itself. Once completed, your modem is ready for use.

Click the Refresh or Reload button in your Web browser. The changes may have occurred, but the W eb browser may be caching the old configuration settings. In this case clear your web browser cache and refresh again.

Internet / ISP Connection

ADSL link

If your ADSL Modem is unable to access the Internet, you should first determine whether you have an ADSL link with the service provider. The state of this connection is indicated with the WAN LED.

WAN LED is Yellow

If your WAN LED is yellow, then you have a good ADSL connection. You can be confident that the service provider has connected you line correctly and that your wiring is correct.

WAN LED is Blinking

If your WAN LED is blinking then your ADSL Modem is attempting to make an ADSL connection with the service provider. The LED should stop blinking and stay on within two minutes.

If the WAN LED does not stay on, disconnect all telephones on the line. If this solves the problem, reconnect the telephones one at a time, being careful to use a microfilter on each telephone. If the microfilters are connected correctly, you should be able to connect all your telephones.

If disconnecting telephones does not return the WAN LED to yellow, there may be a problem with your wiring. If the telephone company has tested the ADSL signal at your Network Interface Device (NID), then you may have poor quality wiring in your house.

Obtaining a W AN IP Address

If your ADSL Modem is unable to access the internet, and your WAN LED is yellow or blinking, you should determine whether your ADSL Modem is able to obtain a WAN IP address from the ISP.

Unless you have been assigned a static IP address, your ADSL Modem must request an IP address from the ISP. You can determine whether the request was successful using the browser interface.

To check the WAN IP address from the browser interface:

1. Launch your browser and select an external site such as www.netcomm.com.au

2. Access the Main Menu of the ADSL Modem’s configuration at http://192.168.1.1

3. Under the Router menu, check that an IP address is shown for the WAN Port. I If nothing is shown, your ADSL Modem has not obtained an IP address from your ISP.

If your ADSL Modem is unable to obtain an IP address from the ISP, the problem may be one of the following:

■ Y our ISP may require a login program.

■ Ask your ISP whether they require PPP over Ethernet (PPPoE) or PPP over ATM

(PPPoA) login.

■ If you have selected a login program, you may have incorrectly set the Service Name,

User Name and Password. See “PPPoE or PPPoA”, below.

www.netcomm.com.au Rev. 1- YML709 Page 94 NB1300Plus4 ADSL Modem

■ Your ISP may check for your computer's host name. Assign the computer Host Name of

your ISP account to your ADSL Modem in the browser-based Setup Wizard.

■ Your ISP only allows one MAC address to connect to Internet, and may check for your

computer’s MAC address. In this case, inform your ISP that you have bought a new network device, and ask them to use your ADSL Modem’s MAC address.

PPPoE or PPPoA

The PPPoE or PPPoA connection can be debugged as follows:

1. Access the Main Menu of the ADSL Modem’s configuration at http://192.168.1.1.

2. Under the PPP menu you can view the PPP configuration settings depending on your

connection type.

3. If the PPP menu shows the PPP connection type as connected, the connection is up and working.

4. If there is no PPP connection listed in the menu, check your connection settings in the main menu.

If you cannot connect after several minutes, you may be using an incorrect Service Name, User Name or Password. There also may be a provisioning problem with your ISP.

Internet Browsing

If your ADSL Modem can obtain an IP address but your computer is unable to load any web pages from the Internet:

■ Your computer may not recognize any DNS server addresses.

A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS servers for your use. If you entered a DNS address during the modem’s configuration, reboot your computer and verify the DNS address. Alternatively, you may configure your computer manually with DNS addresses, as explained in your operating system documentation.

■ Your computer may not have the ADSL Modem configured as its TCP/IP gateway.

If your computer obtains its information from the Modem by DHCP, reboot your computer and verify the modem’s address.

T esting your TCP/IP Network Using a Ping Utility

Most TCP/IP terminal devices and ADSL Modems contain a ping utility that sends an echo request packet to a designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP network is made very easy by using the ping utility in your computer.

T esting the LAN Path to Y our ADSL Modem

You can ping the ADSL Modem from your computer to verify that the LAN path to your modem is working.

T o ping the modem from a computer running Windows 95 or later:

1. From the Windows toolbar, click the Start button and select Run.

2. In the field provided, type Ping followed by the IP address of the ADSL Modem, as in this example:

ping 192.168.1.1

3. Click OK. Y ou should see a message like this one:

Pinging <IP address> with 32 bytes of data

If the path is working, you see this message:

Reply from < IP address >: bytes=32 time=xx ms

TTL=xxx

If the path is not working, you see this message:

Request timed out

If the path is not functioning correctly, you could have one of the following problems:

■ Wrong physical connections

■ Make sure the LAN LED is on.

■ Check that the corresponding Link LEDs are on for your network interface card and for

any hub ports that are connected to your computer and ADSL Modem.

■ Wrong network configuration

■ Verify that the Ethernet card driver software and TCP/IP software are both installed and

configured on your computer or workstation.

■ Verify that the IP address for your ADSL Modem and your computer are correct and

that the addresses are on the same subnet.

www.netcomm.com.au Rev. 1- YML709 Page 96 NB1300Plus4 ADSL Modem

Testing the Path from Y our Computer to a Remote Device

After verifying that the LAN path works correctly, test the path from your computer to a remote device.

From the Windows run menu, type:

PING -n 10 <IP address>

where <IP address> is the IP address of a remote device such as your ISP’s DNS server. If the path is functioning correctly, replies as in the previous section are displayed. If you do not

receive replies:

■ Check that your computer has the IP address of your ADSL Modem listed as the default

gateway. If the IP configuration of your computer is assigned by DHCP, this information will not be visible in your computer’s Network Control Panel. Go to the Run… window and run winipcfg. Verify that the IP address of your ADSL Modem is listed as the default gateway.

■ Check to see that the network address of your computer (the portion of the IP address

specified by the netmask) is different from the network address of the remote device.

Appendix C - Glossary

ADSL: Asymmetric Digital Subscriber Line (ADSL), as its name indicates, is an

asymmetrical data transmission technology with higher traffic rate downstream and lower traffic rate upstream. ADSL technology satisfies the bandwidth requirements of applications which demand asymmetric traffic, such as web surfing, file downloads, and telecommuting.

Bandwidth: The amount of data that can be transmitted in a fixed amount of time. DHCP: Dynamic Host Configuration Protocol (DHCP) is a protocol for

assigning dynamic IP Addresses to devices on a network. Dynamic Addressing means that a device can have a different IP Address each time it connects to the network.

DNS: Domain Name Server (DNS), translates domain names into IP Addresses.

T o help us recognize and remember domain names they are alphabetic in form, however, the Internet actually runs on numbered IP Addresses. DNS servers translate domain names into their respective IP Addresses.

Ethernet: One of the most common Local Area Network (LAN) standards.

Ethernet uses a bus topology which supports a data transfer rate of 10 or 100 Mbps.

DMZ: In computer networks, a DMZ (demilitarized zone) is a computer host

or small network inserted as a "neutral zone" between a company's private network and the outside public network. It prevents outside users from getting direct access to a server that has company data. A DMZ is an optional and more secure approach to a firewall and effectively acts as a proxy server as well.

Domain Name: A name that identifies one or more IP Addresses. For example, the

domain name microsoft.com represents about a dozen IP Addresses. Domain names are used in URLs to identify particular Web pages. For example, in the URL http://www.pcwebopedia.com/index.html, the domain name is pcwebopedia.com.

Firewall: A security system used to enforce an access control policy between an

organisation’s networks and the Internet.

Gateway: A gateway is a network point that acts as an entrance to another

network.

IPSec: Internet Protocol Security is a security standard for network

transmission, which is often used for VPN connections. It provides authentication and packet encryption over the Internet.

LAN: Local Area Network (LAN) is a computer network that spans a

relatively small area. A system of LANs connected is called a wide area network (WAN).

MAC Address: Media Access Control Address (MAC) is a hardware address that

uniquely identifies each node of a network.

NAT: Network Address Translation (NAT) is a routing protocol that allows

global IP Addresses to be translated into multiple private IP Addresses for use on internal LAN networks. The explosion in the use of the Internet has created a critical problem for the Internet Assigned Numbers Authority (IANA) which is in charge of assigning IP Addresses to Internet users, ISPs etc. NAT is a technology that has been introduced to help maximize the utilization of assigned IANA and global IP Addresses.

P AP/CHAP: Password Authentication Protocol and Challenge Handshake

Authentication Protocol (PAP/CHAP). Most ISPs use either one for user identification. If your ISP doesn’t support these two protocols, contact them for an authentication script.

PCI: Peripheral Component Interconnect (PCI) is a specification introduced

by Intel Corporation that defines a local bus system that allows up to 10 PCI-compliant expansion cards to be installed in the computer.

PPP: Short for Point-to-Point Protocol, a communications protocol for

transmitting information over standard telephone lines between devices from different manufacturers.

PPPoE: Short for PPP over Ethernet, relying on two widely accepted standards,

Ethernet and the Point-to-Point Protocol. PPPoE is a communications protocol for transmitting information over the Ethernet between devices from different manufacturers.

Router: An Internet device that routes requests for information to other routers

until the information’s location is found and the data can be transmitted back to the origin of the request.

TCP/IP: Short for Transmission Control Protocol and Internet Protocol, the suite

of communications protocols that enable hosts on the Internet to connect and exchange streams of data.

MRU: Maximum Receive Unit indicates the peer of PPP connection the

maximum size of the PPP information field this device can be received. The default value is 1492 and is used in the beginning of the PPP negotiation. In the normal negotiation, the peer will accept this MRU and will not send packet with information field larger than this value.

MTU: Maximum Transmission Unit indicates the network stack of any packet

is larger than this value will be fragmented before the transmission. During the PPP negotiation, the peer of the PPP connection will indicates its MRU and will be accepted. The actual MTU of the PPP connection will be set to the smaller one of MTU and the peer’s MRU. The default is value 1492.

MSS: Maximum Segment Size is the largest size of data that TCP will send in a

single IP packet. When a connection is established between a LAN client and a host in the WAN side, the LAN client and the WAN host will indicate their MSS during the TCP connection handshake. The default value is 1432.

UBR: Short for Unspecified bit rate. WAN: Wide Area Network. A System of LANs connected by telephone lines

and/or radio waves.
