Wireless LAN Networking

This section provides background information on wireless LAN networking technology. Consult

the Glossary for definitions of the terminology used in this section.

NETWORK SETTINGS AND PARTICULARLY SECURITY SETTTINGS SHOULD ONLY BE DONE BY AN AUTHORIZED ADMINISTRATOR.

Transmission Rate (Transfer Rate)

The SMCWBR14-N provides various transmission (data) rate options for you to select. In most networking scenarios, the factory default Best (automatic) setting proves the most efficient. This setting allows your SMCWBR14-N to operate at the maximum transmission (data) rate. When the communication quality drops below a certain level, the SMCWBR14-N automatically switches to a lower transmission (data) rate. Transmission at lower data speeds is usually more reliable. However, when the communication quality improves again, the SMCWBR14-N gradually increases the transmission (data) rate again until it reaches the highest available transmission rate.

Types of Wireless Networks

Wireless LAN networking works in either of the two modes: ad-hoc and infrastructure. In infrastructure mode, wireless devices communicate to a wired LAN via access points. Each access point and its wireless devices are known as a Basic Service Set (BSS). An Extended Service Set (ESS) is two or more BSSs in the same subnet. In ad hoc mode (also known as peer-to-peer mode), wireless devices communicate with each other directly and do not use an access point. This is an Independent BSS (IBSS).

To connect to a wired network within a coverage area using access points, set the operation mode to Infrastructure (BSS). To set up an independent wireless workgroup without an access point, use Ad-hoc (IBSS) mode.

D-HOC (IBSS) NETWORK

Ad-hoc mode does not require an access point or a wired network. Two or more wireless stations communicate directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service Set (IBSS).

To set up an ad-hoc network, configure all the stations in ad-hoc mode. Use the same SSID and channel for each station.

When a number of wireless stations are connected using a single access point, you have a Basic Service Set (BSS).

In the ESS diagram below, communication is done through the access points, which relay data packets to other wireless stations or devices connected to the wired network. Wireless stations can then access resources, such as a printer, on the wired network.

In an ESS environment, users are able to move from one access point to another without losing the connection. In the diagram below, when the user moves from BSS (1) to BSS (2) the WLAN client devices automatically switches to the channel used in BSS (2).

Introduction

The SMCWBR14-N is a high-performance, wireless router that supports high-speed wireless networking at home, at work or in public places.

Unlike most routers, the SMCWBR14-N provides data transfers at up to 300Mbps when using 11n (Draft) connection. This router is also backwards compatible with 802.11g or 11b devices. This means that you do not need to change your entire network to maintain connectivity. You may sacrifice some of 11n’s (Draft) speed when you mix 11n (Draft) and 11b/g devices, but you will not lose the ability to communicate when you incorporate the 11n (Draft) standard into your 11b/g network. You may choose to slowly change your network by gradually replacing the 11b/g devices with 11n (Draft) devices.

Installation Considerations

The SMCWBR14-N lets you access your network, using a wireless connection, from virtually anywhere within its operating range. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines:

1 Keep the number of walls and ceilings between the SMCWBR14-N and other network devices

to a minimum - each wall or ceiling can reduce your wireless product’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized.

2 Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at

a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception.

3 Building Materials can impede the wireless signal - a solid metal door or aluminum studs may

have a negative effect on range. Try to position wireless devices and computers with wireless adapters so that the signal passes through drywall or open doorways and not other materials.

4 Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances

that generate extreme RF noise.

Getting Started

For a typical home setup, you will need a Broadband (Cable/xDSL) Internet service and Modem with Ethernet connection. Consult with your Cable or xDSL provider for proper installation of the modem. Please do the following:

1. Connect your Broadband modem (Cable/xDSL) to the blue WAN port on the Barricade™

Basic

The Basic tab provides the following configuration options: INTERNET, WIRELESS and NETWORK SETTINGS.

Basic_Internet

Setup Wizard

If you are new to networking and have never configured a router before, click on Setup Wizard

and the router will guide you through a few simple steps to get your network up and running.

Manual Configure

If you consider yourself an advanced user and have configured a router before, click Manual Configure to input all the settings manually.

Basic_Wireless

The wireless section is used to configure the wireless settings for your router. Note that changes made in this section may also need to be duplicated on wireless clients that you want to connect to your wireless network.

To protect your privacy, use the wireless security mode to configure the wireless security features. This device supports three wireless security modes including: WEP, WPA-Personal, and WPA-Enterprise. WEP is the original wireless encryption standard. WPA-Enterprise provides a higher level of security. WPA-Personal does not require an authentication server. The WPA-Enterprise option requires a RADIUS authentication server.

Enable Wireless

This option allows you to enable/disable the wireless AP function. The wireless can also be turned ON/OFF by the slide switch on the back panel. When the wireless is enabled, the following parameters are in effect.

Wireless Network Name

When you are browsing for available wireless networks, this is the name that will appear in the list (unless Visibility Status is set to Invisible, see below). This name is also referred to as the SSID. For security purposes, it is highly recommended to change from the pre-configured network name.

Enable Auto Channel Scan

If you select this option, the router automatically finds the channel with least interference and uses that channel for wireless networking. If you disable this option, the router uses the

channel that you specify with the following Wireless Channel option.

Wireless Channel

A wireless network uses specific channels in the wireless spectrum to handle communication between clients. Some channels in your area may have interference from other electronic devices. Choose the clearest channel to help optimize the performance and coverage of your wireless network.

802.11 Mode

If all of the wireless devices you want to connect with this router can connect in the same transmission mode, you can improve performance slightly by choosing the appropriate "Only" mode. If you have some devices that use a different transmission mode, choose the appropriate "Mixed" mode.

Channel Width

The "Auto 20/40 MHz" option is usually best. The other options are available for special circumstances. Note that when 20/40MHz option is selected, an extended channel will be used to extend the data rate.

Transmission Rate

By default the fastest possible transmission rate will be selected. You have the option of selecting the speed if necessary.

Visibility Status

The Invisible option allows you to hide your wireless network. When this option is set to Visible, your wireless network name is broadcast to anyone within the range of your signal. If you're not using encryption then they could connect to your network. When Invisible mode is enabled, you must enter the Wireless Network Name (SSID) on the client manually to connect to the network.

Security Mode (NONE, WEP, WPA-Personal, WPA-Enterprise)

Unless one of these encryption modes is selected, wireless transmissions to and from your wireless network can be easily intercepted and interpreted by unauthorized users.

WEP

A method of encrypting data for wireless communication intended to provide the same level of privacy as a wired network. WEP is not as secure as WPA encryption. To gain access to a

WEP network, you must know the key. The key is a string of characters that you create. When using WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange - alphanumeric characters) format. ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX for use over the network. Four keys can be defined so that you can change keys easily. A default key is selected for use on the network.

Example:

64-bit hexadecimal keys are exactly 10 characters in length. (12345678FA is a valid string of 10 characters for 64-bit encryption.)

128-bit hexadecimal keys are exactly 26 characters in length. (456FBCDF123400122225271730 is a valid string of 26 characters for 128-bit encryption.)

64-bit ASCII keys are up to 5 characters in length (DMODE is a valid string of 5 characters for 64-bit encryption.)

128-bit ASCII keys are up to 13 characters in length (2002HALOSWIN1 is a valid string of 13 characters for 128-bit encryption.)

Note that, if you enter fewer characters in the WEP key than required, the remainder of the key is automatically padded with zeros.

WPA-Personal and WPA-Enterprise

Both of these options select some variant of Wi-Fi Protected Access (WPA) -- security

standards published by the Wi-Fi Alliance. The WPA Mode further refines the variant that the

router should employ.

WPA Mode: WPA is the older standard; select this option if the clients that will be used with

the router only support the older standard. WPA2 is the newer implementation of the stronger IEEE 802.11i security standard. With the "WPA or WPA2" option, the router tries WPA2 first, but falls back to WPA if the client only supports WPA. The strongest cipher that the client supports will be used. With the "WPA2 Only" option, the router associates only with clients that also support WPA2 security. If the clients support the AES cipher, it will be used across the wireless network to ensure best security.

Group Key Update Interval: The amount of time before the group key used for broadcast and

multicast data is changed.

WPA-Personal

This option uses Wi-Fi Protected Access with a Pre-Shared Key (PSK).

Pre-Shared Key: The key is entered as a pass-phrase of up to 63 alphanumeric characters in

ASCII (American Standard Code for Information Interchange) format at both ends of the wireless connection. It cannot be shorter than eight characters, although for proper security it needs to be of ample length and should not be a commonly known phrase. This phrase is used to generate session keys that are unique for each wireless client.

Example:

Wireless Networking technology enables ubiquitous communication

WPA-Enterprise

This option works with a RADIUS Server to authenticate wireless clients. Wireless clients should have established the necessary credentials before attempting to authenticate to the Server through this Gateway. Furthermore, it may be necessary to configure the RADIUS Server to allow this Gateway to authenticate users.

Authentication Timeout: Amount of time before a client will be required to re-authenticate. RADIUS Server IP Address: The IP address of the authentication server. RADIUS Server Port: The port number used to connect to the authentication server. RADIUS Server Shared Secret: A pass-phrase that must match with the authentication

server.

MAC Address Authentication: If this is selected, the user must connect from the same

computer whenever logging into the wireless network.

Advanced: Optional Backup RADIUS Server

This option enables configuration of an optional second RADIUS server. A second RADIUS server can be used as backup for the primary RADIUS server. The second RADIUS server is consulted only when the primary server is not available or not

responding. The fields Second RADIUS Server IP Address, RADIUS Server Port, Second RADIUS server Shared Secret, Second MAC Address Authentication provide

the corresponding parameters for the second RADIUS Server.

Basic_Network Settings

Use this section to configure the internal network settings of your router. The IP Address that is configured here is the IP Address that you use to access the Web-based management interface. If you change the IP Address here, you may need to adjust your PC’s network settings to access the network again.

Router Settings

These are the settings of the LAN (Local Area Network) interface for the router. The router's local network (LAN) settings are configured based on the IP Address and Subnet Mask assigned in this section. The IP address is also used to access this Web-based management interface. It is recommended that you use the default settings if you do not have an existing network.

IP Address

The IP address of your router on the local area network. Your local area network settings are based on the address assigned here. For example, 192.168.2.1.

Subnet Mask

The subnet mask of your router on the local area network.

Local Domain Name

This entry is optional. Enter a domain name for the local network. The router's DHCP server will give this domain name to the computers on the wireless LAN. So, for example,

if you enter mynetwork.net here, and you have a wireless laptop with a name of chris, that laptop will be known as chris.mynetwork.net. Note, however, if the router's settings

specify "DHCP (Dynamic)" Address, and the router's DHCP server assigns a domain name to the AP, that domain name will override any name you enter here.

DNS Relay

When DNS Relay is enabled, the router plays the role of a DNS server. DNS requests sent to the router are forwarded to the ISP's DNS server. This provides a constant DNS address that LAN computers can use, even when the router obtains a different DNS server address from the ISP upon re-establishing the WAN connection. You should disable DNS relay if you implement a LAN-side DNS server as a virtual server.

RIP (Routing Information Protocol)

Used to broadcast routing information among routers.

Enable RIP

Enable RIP if required by the ISP, if the LAN has multiple routers, or if the LAN has auto-IP devices.

RIP Operating mode

This router supports both version 2 and version 1 of the RIP specification.

V1. Use if none of the routers supports Version 2. V2 Broadcast. Use if some routers are capable of Version 2, but some are only capable

of Version 1.

V2 Multicast. Use if this is the only router on the LAN or if all the routers support Version

Router Metric

The additional cost of routing a packet through this router. The normal value for a simple network is 1. This metric is added to routes learned from other routers; it is not added to static or system routes.

Act as default router

Make this router the preferred destination for packets that are not otherwise destined.

Allow RIP updates from WAN

For security, disable this option unless required by the ISP.

RIP Password

RIP Version 2 supports the use of a password to limit access to routers through the RIP protocol. If the ISP or other LAN router requires a RIP password, enter the password here.

DHCP Server Settings

DHCP stands for Dynamic Host Configuration Protocol. The DHCP section is where you configure the built-in DHCP Server to assign IP addresses to the computers and other devices on your local area network (LAN).

Enable DHCP Server

Once your router is properly configured and this option is enabled, the DHCP Server will manage the IP addresses and other network configuration information for computers and other devices connected to your Local Area Network. There is no need for you to do this yourself.

The computers (and other devices) connected to your LAN also need to have their TCP/IP configuration set to "DHCP" or "Obtain an IP address automatically".

When you set Enable DHCP Server, the following options are displayed.

DHCP IP Address Range

These two IP values (from and to) define a range of IP addresses that the DHCP Server

uses when assigning addresses to computers and devices on your Local Area Network. Any addresses that are outside of this range are not managed by the DHCP Server; these could, therefore, be used for manually configured devices or devices that cannot use DHCP to obtain network address details automatically.

It is possible for a computer or device that is manually configured to have an address that does reside within this range. In this case the address should be reserved (see Static

DHCP Client below), so that the DHCP Server knows that this specific address can only

be used by a specific computer or device.

Your router, by default, has a static IP address of 192.168.2.1. This means that addresses

192.168.2.2 to 192.168.2.254 can be made available for allocation by the DHCP Server.

Example:

Your router uses 192.168.2.1 for the IP address. You've assigned a computer that you want to designate as a Web server with a static IP address of 192.168.2.3. You've assigned another computer that you want to designate as an FTP server with a static IP address of 192.168.2.4. Therefore the starting IP address for your DHCP IP address range needs to be 192.168.2.5 or greater.

Example:

Suppose you configure the DHCP Server to manage addresses From: 192.168.2.100 To: 192.168.2.199. This means that 192.168.2.3 to 192.168.2.99 and 192.168.2.200 to

192.168.2.254 are NOT managed by the DHCP Server. Computers or devices that use addresses from these ranges are to be manually configured. Suppose you have a web server computer that has a manually configured address of 192.168.2.100. Because

this falls within the "managed range" be sure to create a reservation for this address and match it to the relevant computer (see Static DHCP Client below).

DHCP Lease Time

The amount of time that a computer may have an IP address before it is required to renew the lease. The lease functions just as a lease on an apartment would. The initial lease designates the amount of time before the lease expires. If the tenant wishes to retain the address when the lease is expired then a new lease is established. If the lease expires and the address is no longer needed than another tenant may use the address.

Always Broadcast

If all the computers on the LAN successfully obtain their IP addresses from the router's DHCP server as expected, this option can remain disabled. However, if one of the computers on the LAN fails to obtain an IP address from the router's DHCP server, it may have an old DHCP client that incorrectly turns off the broadcast flag of DHCP packets. Enabling this option will cause the router to always broadcast its responses to all clients, thereby working around the problem, at the cost of increased broadcast traffic on the LAN.

Add/Edit DHCP Reservation

This option lets you reserve IP addresses, and assign the same IP address to the network device with the specified MAC address any time it requests an IP address. This is almost the same as when a device has a static IP address except that the device must still request an IP address from the router. The router will provide the device the same IP address every time. DHCP Reservations are helpful for server computers on the local network that are hosting applications such as Web and FTP. Servers on your network should either use a static IP address or use this option.

Computer Name

You can assign a name for each computer that is given a reserved IP address. This may

help you keep track of which computers are assigned this way. Example: Game Server.

IP Address:

The LAN address that you want to reserve.

MAC Address

To input the MAC address of your system, enter it in manually or connect to the router's

Web-Management interface from the system and click the Copy Your PC’s MAC Address button.

A MAC address is usually located on a sticker on the bottom of a network device. The MAC address is comprised of twelve digits. Each pair of hexadecimal digits are usually separated by dashes or colons such as 00-0D-88-11-22-33 or 00:0D:88:11:22:33. If your network device is a computer and the network card is already located inside the computer,

you can connect to the router from the computer and click the Copy Your PC’s MAC Address button to enter the MAC address.

As an alternative, you can locate a MAC address in a specific operating system by following the steps below:

Windows 98 Windows Me

Windows 2000 Windows XP

Mac OS X Go to the Apple Menu, select System Preferences, select Network, and

DHCP Reservations List

This shows clients that you have specified to have reserved DHCP addresses. An entry can be changed by clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and the "Edit DHCP Reservation" section is activated for editing.

Number of Dynamic DHCP Clients

In this section you can see what LAN devices are currently leasing IP addresses.

Go to the Start menu, select Run, type in winipcfg, and hit Enter. A

popup window will be displayed. Select the appropriate adapter from the pull-down menu and you will see the Adapter Address. This is the MAC address of the device.

Go to your Start menu, select Programs, select Accessories, and select

Command Prompt. At the command prompt type ipconfig /all and hit

Enter. The physical address displayed for the adapter connecting to the router is the MAC address.

select the Ethernet Adapter connecting to the router. Select the Ethernet button and the Ethernet ID will be listed. This is the same as the MAC address.

Revoke

The Revoke option is available for the situation in which the lease table becomes full or

nearly full, you need to recover space in the table for new entries, and you know that

some of the currently allocated leases are no longer needed. Clicking Revoke cancels the

lease for a specific LAN device and frees an entry in the lease table. Do this only if the device no longer needs the leased IP address, because, for example, it has been removed from the network.

Reserve

The Reserve option converts this dynamic IP allocation into a DHCP Reservation and

adds the corresponding entry to the DHCP Reservations List.

Advanced

The Advanced tab provides the following configuration options: Virtual Server, Special Applications, Gaming, StreamEngine, Routing, Access Control, WEB Filter, MAC Address Filter, Firewall, Inbound Filter, Advanced Wireless and Advanced Network.

Advanced_Virtual Server

The Virtual Server option gives Internet users access to services on your LAN. This feature is useful for hosting online services such as FTP, Web, or game servers. For each Virtual Server, you define a public port on your router for redirection to an internal LAN IP Address and LAN port.

Example:

You are hosting a Web Server on a PC that has LAN IP Address of 192.168.2.50 and your ISP is blocking Port 80.

1. Name the Virtual Server (for example: Web Server)

2. Enter the IP Address of the machine on your LAN (for example: 192.168.2.50

3. Enter the Private Port as [80]

4. Enter the Public Port as [8888]

5. Select the Protocol (for example TCP).

6. Ensure the schedule is set to Always

7. Click Save to add the settings to the Virtual Servers List

8. Repeat these steps for each Virtual Server Rule you wish to add. After the list is

complete, click Save Settings at the top of the page.

With this Virtual Server entry, all Internet traffic on Port 8888 will be redirected to your internal web server on port 80 at IP Address 192.168.2.50.

Virtual Server Parameters

Name

Assign a meaningful name to the virtual server, for example Web Server. Several

well-known types of virtual server are available from the "Application Name" drop-down list. Selecting one of these entries fills some of the remaining parameters with standard values for that type of server.

IP Address

The IP address of the system on your internal network that will provide the virtual service,

for example 192.168.2.50. You can select a computer from the list of DHCP clients in the

"Computer Name" drop-down menu, or you can manually enter the IP address of the server computer.

Protocol

Select the protocol used by the service. The common choices -- UDP, TCP, and both UDP and TCP -- can be selected from the drop-down menu. To specify any other protocol, select "Other" from the list, then enter the corresponding protocol number ( as assigned

by the IANA) in the Protocol box.

Private Port

The port that will be used on your internal network.

Public Port

The port that will be accessed from the Internet.

Inbound Filter

Select a filter that controls access as needed for this virtual server. If you do not see the filter you need in the list of filters, go to the Advanced → Inbound Filter screen and create a new filter.

Schedule

Select a schedule for when the service will be enabled. If you do not see the schedule you need in the list of schedules, go to the Tools → Schedules screen and create a new schedule.

Add/Edit Virtual Server

In this section you can add an entry to the Virtual Servers List below or edit an existing entry.

Enable

Entries in the list can be either active (enabled) or inactive (disabled).

Save

Saves the new or edited virtual server entry in the following list. When finished updating

the virtual server entries, you must still click the Save Settings button at the top of the

page to make the changes effective and permanent.

Virtual Servers List

The section shows the currently defined virtual servers. A Virtual Server can be changed by clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and the "Edit Virtual Server" section is activated for editing.

You might have trouble accessing a virtual server using its public identity (WAN-side IP-address of the gateway or its dynamic DNS name) from a machine on the LAN. Your requests may not be looped back or you may be redirected to the "Forbidden" page.

This will happen if you have an Access Control Rule configured for this LAN machine.

The requests from the LAN machine will not be looped back if Internet access is blocked at the time of access. To work around this problem, access the LAN machine using its LAN-side identity.

Requests may be redirected to the "Forbidden" page if web access for the LAN machine is restricted by an Access Control Rule. Add the WAN-side identity (WAN-side IP-address of the router or its dynamic DNS name) on the Advanced → Web Filter screen to work around this problem.

Advanced_Special Applications

An application rule is used to open single or multiple ports on your router when the router senses data sent to the Internet on a "trigger" port or port range. An application rule applies to all computers on your internal network.

Parameters for an Application Rule

Example:

You need to configure your router to allow a software application running on any computer on your network to connect to a web-based server or another user on the Internet.

Name

Enter a name for the Special Application Rule, for example Game App, which will help you identify the rule in the future. Alternatively, you can select from the Application list of

common applications.

Application

Instead of entering a name for the Special Application rule, you can select from this list of common applications, and the remaining configuration values will be filled in accordingly.
