5. Internet Setup

The physical connections determine whether the router ports are local area network (LAN) ports or wide area network (WAN) ports. There are two kinds of IP networks. The local, private kind is the LAN network; the global, public kind is the WAN network. The following illustration shows the relationship between the router and the two different networks.

A LAN is a shared communication system to which many computers are attached. A LAN is generally limited to the immediate area, usually the same building or floor of a building. A WAN is an outside connection to another network or to the Internet.

5.1 Configuring your Internet Connection

The advance setup screen allows you to set up how your router connects to the Internet. If you already ran the Quick Start wizard, the information you provided to the wizard should be entered into the fields already. After you finish the changes, click on the SAVE button to save your changes.

WF250 802.11n Wireless ADSL Modem Router

5.1.1 ATM Setup

ATM settings are used to connect to your ISP. Your ISP provides VPI, VCI, settings to you. In this Device, you can totally setup 16 PVCs on different encapsulations if you apply 16 different virtual circuits from your ISP.

From Layer2 Interface, click ATM Interface. Choose Add, or Remove to configure DSL ATM interfaces

Click Add to configure PVC identifier, select DSL latency and select connection mode according to your local occasion. After the configuration, you need to click Apply/Save

WF250 802.11n Wireless ADSL Modem Router

VPI: Virtual Path Identifier. The valid range for the VPI is 0 to 255. The default values are 0 / 35 respectively. VCI: Virtual Channel Identifier. The valid range for the VCI is 1 to 65635 (0 to 31 is reserved for local management of ATM traffic). Select the values for VRI and VCI (Most common setting is VRI:8 and VCI:35 for Greek ISPs).

DSL Latency: Select DSL Latency to Path0 DSL Link Type: PPPoA / PPPoE: Select this option if your ISP requires you to use a

PPPoE/PPPoA connection. This option is typically used for DSL service. EoA is for PPPoE

Connection Mode: Select the default mode Encapsulation: Select VC/MUX or LLC/Snap-Bridging Service Category:

PCR: Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a maximum speed of 832 Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is dependent on the line speed. CBR is for connections that support constant rates of data transfer. The only parameter you need to worry about in CBR is PCR. UBR is for connections that have variable traffic. The only parameter you need to worry about in UBR is PCR.

Authentication method is default to auto. It is recommended that you leave the Authentication method in Auto. However, you may select PAP or CHAP if necessary. The default value for MTU (Maximum Transmission Unit) is 1500 for PPPoA and 1492 for PPPoE. Do not change these values unless your ISP asks you to.

Enable FullCone NAT, all requests from the same private IP address and port are mapped to the same public source IP address and port. Someone on the Internet only needs to know the mapping scheme in order to send packets to a device behind the ADSL router.

The gateway can be configured to disconnect if there is no activity for a specific period of time by selecting the Dial on demand check box and entering the Inactivity timeout. The entered value must be between 1 minute and 4320 minutes.

WF250 802.11n Wireless ADSL Modem Router

The PPP IP Extension is a special feature deployed by some service providers. Unless your service provider specifically requires this setup, do not select it. If you need to select it, the PPP IP Extension supports the following conditions:

 It allows only one computer on the LAN.  The public IP address assigned by the remote using the PPP/IPCP

protocol is actually not used on the WAN PPP interface. Instead, it is forwarded to the computer's LAN interface through DHCP. Only one system on the LAN can be connected to the remote, since the DHCP server within the ADSL gateway has only a single IP address to assign to a LAN device.

 NAPT and firewall are disabled when this option is selected.  The gateway becomes the default gateway and DNS server to the

computer through DHCP using the LAN interface IP address.

 The gateway extends the IP subnet at the remote service provider to the

LAN computer. That is, the PC becomes a host belonging to the same IP subnet.

 The ADSL gateway bridges the IP packets between WAN and LAN ports,

unless the packet is addressed to the gateway's LAN IP address.

Use static IPv4 IP address, If the ISP gave you a static IP address, select this option and enter it in the IP address field.

Bridge PPPoE Frames between WAN and Local Ports is available when you do not use PPP IP extension. If you enable this function, LAN hosts can use PPPoE client software on their computers to connect to the ISP. Each host can have a separate account and a public WAN IP address.

4. Select a preferred wan interface as the system default gateway.

WF250 802.11n Wireless ADSL Modem Router

5. Get DNS server information from the selected WAN interface or enter static DNS server IP addresses. If only a single PVC with IPoA or static MER protocol is configured, you must enter static DNS server IP addresses.

Make sure that the settings above match the settings provided by your ISP.

Click on the Apply/Save button to save your configurations.

5.2 LAN

There are the IP settings of the LAN Interface for the device. These settings may be referred to as Private settings. You may change the LAN IP address if needed. The LAN IP address is provided to your internal network and cannot be seen on the Internet. From LAN you can configure the DSL Router’s IP Address and Subnet Mask for LAN interface. In this page, you can use DHCP (Dynamic Host Configuration Protocol) to control the assignment of IP addresses on your local network (LAN only).

Item Description IP address

This is the IP address that other devices on your local network will use to connect to the modem.

Subnet mask

This defines the size of your network. The default is

255.255.255.0.

Enable IGMP snooping

IGMP Snooping is a method that actually “snoops” or inspects IGMP traffic on a switch. When enabled, the switch will watch for IGMP messages passed between a host and a router, and will add the necessary ports to its multicast table, ensuring that only the ports that require a given multicast stream actually receive it. Use standard mode to flood unknown multicast traffic. Use blocking mode to discard unknown multicast traffic.

Disable / Enable DHCP server

The DHCP server assigns an IP addresses from a pre-set pool of addresses upon request from DHCP client (e.g. your computer). Do not disable the DHCP server unless you wish to let another device handle IP address issuance on the local network.

WF250 802.11n Wireless ADSL Modem Router

Start / end IP address

This is the beginning and ending range for the DHCP server addresses.

Leased time

The amount of time before the IP address is refreshed by the DHCP server.

Configure the second IP address and...

Select this option to let the device use a second IP address on the LAN interface. You can also use this second IP address to access the device for management. Enter the LAN IP address of your device in dotted decimal notation, for example, 10.0.0.1. Type the subnet mask.

There are four selections including Open, Shared, 802.1X, WPA, WPA-PSK, WPA2, WPA2-PSK, Mixed WPA-WPA2, Mixed WPA-WPA2-PSK.

WF250 802.11n Wireless ADSL Modem Router

There are several security methods to choose from, depending on user’s

needs and the capabilities of user’s wireless machines.

 WEP open and WEP shared —WEP is an encryption scheme that is used

to protect user’s wireless data communications. WEP uses a combination of 64-bit keys or 128-bit keys to provide access control to user’s network and encryption security for every data transmission. To decode a data transmission, each wireless client on the network must use an identical 64bit or 128-bit key. WEP is an older wireless encryption method that is not as hard to break as the more-recent WPA.

 802.1x — In 802.1x (also known as RADIUS), a separate machine called

an authentication server receives a user ID and password. It grants or denies access based on whether the ID and password match any entries in its account list. User can optionally enable WEP encryption with this option. Because it requires a separate machine acting as the authentication server, 802.1x is most often used in business environments.

 WPA — WPA is a more recent encryption method that addresses many of

the weaknesses in WEP. Any client capable of WPA encryption should use it instead of WEP.

 WPA (PSK) — This is WPA encryption combined with a pre-shared key

(PSK), which is a text string known only to the gateway and authorized

wireless clients. The gateway rejects the login if the client's PSK does not match.

WF250 802.11n Wireless ADSL Modem Router

 WPA2 — WPA2 is a more advanced encryption method than WPA.

Because it is a more recent standard, some of user’s wireless devices might not be able to use it.

 WPA2 (PSK) — This option uses WPA2 with a pre-shared key.  WPA2 and WPA — This option supports WPA2/WPA encryption for

devices capable of one or the other standard. The gateway automatically detects whether a particular device can use WPA2 or WPA.

 WPA2 AND WPA (PSK) — This has WPA2 or WPA encryption based on

client abilities, as well as a pre-shared key.

After making changes, click Apply to save.

6.3.3 Mac Filter

You can allow or deny a list of MAC addresses associated with the wireless stations access to the ADSL Router.

6.3.5 Advanced Settings

This page is where user specifies a number of advanced settings for wireless communications.

Note: After making any changes, click Apply to save.

Warning: The settings shown above are default settings. Changes made to

these items can cause wireless communication problems.

Field Description Band

This is the range of frequencies the gateway will use to communicate with user’s wireless devices.

Channel

Drop-down menu that allows selection of specific channel.

54g

Rate

This drop-down list lets user specify the wireless communication rate, which can be Auto (uses the highest rate when possible, or else a lower rate) or a fixed rate between 1 and 54 Mbps.

WF250 802.11n Wireless ADSL Modem Router

Multicast rate

This drop-down list lets user specify the wireless communication rate for multicast packets, which are sent to more than one destination at a time. The value can be Auto (uses the highest rate when possible, or else a lower rate) or a fixed rate between 1 and 54 Mbps.

Basic rate

User has the option of supporting all rates listed in Rate above or using the 1-, 2-Mbps rates, which support only older 802.11b implementations.

Fragmentation threshold

A threshold, specified in bytes, that determines whether packets will be fragmented and at what size. On an 802.11 connection, packets that are larger the fragmentation threshold are split into smaller units suitable for the circuit size. Packets smaller than the specified fragmentation threshold value are not fragmented.

Enter a value between 256 and 2346. If you experience a high packet error rate, try to increase this value slightly. Setting the fragmentation threshold too low may result in poor performance.

RTS threshold

This is number of bytes in the packet size beyond which the gateway invokes its RTS/CTS (request to send, clear to send) mechanism. Packets larger than this threshold trigger the RTS/CTS mechanism, while the gateway transmits smaller packets without using RTS/CTS. The default setting of 2347, which is the maximum, disables the RTS threshold mechanism.

DTIM interval

A delivery traffic indication message (DTIM), also known as a beacon, is a countdown informing wireless clients of the next window for listening to broadcast and multicast messages. When the gateway has broadcast or multicast messages for its clients, it sends its next DTIM message with this DTIM interval value. The clients hear the beacons and awaken as needed to receive the broadcast and multicast messages.

Beacon interval

The amount of time (in milliseconds) between beacon transmissions, each of which identifies the presence of an access point. By default, wireless clients passively scan all radio channels, listening for beacons coming from access points. Before a client enters power-save mode, it needs the beacon interval to determine when to wake up for the next beacon (and learn whether the access point has any messages for it). User can enter any value between 1 and 65535, but the recommended range is 1 - 1000.

XPress™ Technology

XPress™ Technology is a feature in which two of our devices

can communicate with each other at twice the normal rate. 54g+ is a technology that achieves higher throughput with frame-

bursting. With 54g+ enabled, aggregate throughput (the sum of the individual throughput of each network client) improves by up to 25% in 802.11g-only networks, and up to 75% in mixed networks containing both 802.11g and 802.11b equipment.

6.5.5 TR-069 Client

WAN Management Protocol (TR-069) allows a Auto-Configuration Server (ACS) to perform auto-configuration, provision, collection, and diagnostics to this device. As a bidirectional SOAP

/HTTP based protocol it provides the communication between CPE and Auto Configuration Servers (ACS). It includes both a safe auto configuration and the control of other CPE management functions within an integrated framework. In the course of the boom of the broadband market, the number of different Internet access possibilities grew as well (e.g.

modems, routers, gateways, Set-top box, paddles, VoIP-phones). At the same

WF250 802.11n Wireless ADSL Modem Router

time the configuration of this equipment became more complicated -- too complicated for the end-users. For this reason the TR-069 standard was developed. It provides the possibility of auto configuration of these access types. The technical specifications are managed and published by the DSL

Forum. Using TR-069 the terminals can get in contact with the Auto

Configuration Servers (ACS) and establish the configuration automatically. Accordingly other service functions can be provided. TR-069 is the current standard for activation of terminals in the range of DSL broadband market.

Virtual Private Network. Enables IP traffic to travel securely over a public TCP/IP network by encrypting all traffic from one network to another.

Router Reset

For convenience: shutdown your computer first.

1. Switch the ADSL router OFF.

2. On the Rear Panel of the ADSL router you will find a small ho le with the word "reset" written below it. It's just big enough for a ball-point tip. Insert a ball-point tip, press the reset switch and keep the ballpoint tip in there.

3. Switch the router ON, and hold the ball-point tip in the little hole.

You can release the ball-point after about 10 seconds. You have then completed the full-reset. Your ADSL router will now have its factory default settings. IP address will be 192.168.1.1 and the subnet mask will be

255.255.255.0. Now you can reboot your PC again.

8. Troubleshooting

If the router does not function properly, first check this session for simple troubleshooting before contacting your Internet service provider (ISP) for support.

Using LEDs to Diagnose Problems

The LEDs are useful aides for finding possible problem causes.

Power LED

The PWR LED on the front panel does not light up.

STEPS CORRECTIVE ACTION

1 Make sure that the power adaptor is connected to the router and

plugged in to an appropriate power source. Use only the supplied power adaptor.

2 Check that the router and the power source are both turned on

and the router is receiving sufficient power. 3 Turn the router off and on. 4 If the error persists, you may have a hardware problem. In this

case, you should contact your vendor.

LAN LED

The LAN LED on the front panel does not light up.

STEPS CORRECTIVE ACTION

1 Check the Ethernet cable connections between your router and

the computer or hub. 2 Check for faulty Ethernet cables. 3 Make sure your computer’s Ethernet card is working properly. 4 If these steps fail to correct the problem, contact your local

distributor for assistance.

ADSL LED

The ADSL LED on the front panel does not light up.

STEPS CORRECTIVE ACTION

1 Check the telephone wire and connections between the router

ADSL port and the wall jack. 2 Make sure that the telephone company has checked your phone

line and set it up for ADSL service. 3 Reset your ADSL line to reinitialize your link to the DSLAM. 4 If these steps fail to correct the problem, contact your local

distributor for assistance.

Problems with the Web Interface

I cannot access the web Interface.

STEPS CORRECTIVE ACTION

1 Make sure you are using the correct IP address of the router.

Check the IP address of the router. 2 Make sure that there is not a console session running.

3 Check that you have enabled web service access. If you have

configured a secured client IP address, your computer’s IP

address must match it. 4 For WAN access, you must configure remote management to

allow server access from the WAN (or all). 5 Your computer’s and the router’s IP addresses must be on the

same subnet for LAN access. 6 If you changed the router’s LAN IP address, then enter the new

one as the URL. 7 Remove any filters in LAN or WAN that block web service.

The web Interface does not display properly.

STEPS CORRECTIVE ACTION

1 Make sure you are using Internet Explorer 5.0 and later versions. 2 Delete the temporary web files and log in again.

In Internet Explorer, click Tools, Internet Options and then click

the Delete Files ... button.

When a Delete Files window displays, select Delete all offline

content and click OK. (Steps may vary depending on the version

of your Internet browser.)

Problems with the Login Username and Password

I forgot my login username and/or password.

STEPS CORRECTIVE ACTION

1 If you have changed the password and have now forgotten it, you

will need to upload the default configuration file. This will erase all

custom configurations and restore all of the factory defaults

including the password. 2 Press the RESET button, the defaults have been restored and

the router restarts. 3 The default username is “admin”. The default password is

“adslroot”. The Password and Username fields are case-

sensitive. Make sure that you enter the correct password and

username using the proper casing. 4 It is highly recommended to change the default username and

password. Make sure you store the username and password in a

save place.

Problems with LAN Interface

I cannot access the router from the LAN or ping any computer on the LAN.

STEPS CORRECTIVE ACTION

1 Check the Ethernet LEDs on the front panel. A LAN LED should

be on for a port that has a PC connected. If it is off, check the

cables between your router and the PC. Make sure you have

uninstalled any software firewall for troubleshooting. 2 Make sure that the IP address and the subnet mask is consistent

between the router and the workstation.

Problems with WAN Interface

Initialization of the ADSL connection failed.

STEPS CORRECTIVE ACTION

1 Check the cable connections between the ADSL port and the

wall jack. The ADSL LED on the front panel of the router should

be on. 2 Check that your VPI, VCI, type of encapsulation and type of

multiplexing settings are the same as what you collected from

your telephone company and ISP. 3 Restart the router. If you still have problems, you may need to

verify your VPI, VCI, type of encapsulation and type of

multiplexing settings with the telephone company and ISP.

I cannot get a WAN IP address from the ISP.

STEPS CORRECTIVE ACTION

1 Ensure that all other devices connected to the same telephone

line as your router (e.g. telephones, fax machines, analogue

modems) have a line filter connected between them and the wall

socket (unless your are using a Central Splitter or Central Filter

installed by the qualified and licensed electrician), and ensure

that all line filters are correctly installed and right way around. 2 Missing line filters or line filters installed the wrong way around

can cause problems with your ADSL connection, including

causing frequent disconnects.

Frequent loss of ADSL line sync (disconnections).

STEPS CORRECTIVE ACTION

1 The ISP provides the WAN IP address after authenticating you.

Authentication may be through the user name and password, the

MAC address or the host name. 2 The username and password apply to PPPoE and PPoA

encapsulation only. Make sure that you have entered the correct

Service Type, User Name and Password (be sure to use the

correct casing).

Problems with the Internet Access

I cannot access the Internet.

STEPS CORRECTIVE ACTION

1 Make sure the router is turned on and connected to the network. 2 Verify your WAN settings. 3 Make sure you entered the correct user name and password. 4 For wireless stations, check that both the router and wireless

station(s) are using the same ESSID, channel and WEP keys (if

WEP encryption is activated).

Internet connection disconnects.

STEPS CORRECTIVE ACTION

1 Check the schedule rules. 2 If you use PPPoA or PPPoE encapsulation, check the idle time-

out setting. 3 Contact your ISP.
