Wireless-B Broadband Router
The Setup Tab - Advanced Routing
This tab is used to set up the Router’s advanced functions. Dynamic Routing will automatically adjust how packets
travel on your network. Static Routing sets up a fixed route to another network destination.
NAT. Network Address Translation (NAT) technology translates IP addresses of a local area network to a different
IP address for the Internet. To enable the NAT function, click
Enable
.
Dynamic Routing. With Dynamic Routing you can enable the Gateway to automatically adjust to physical
changes in the network’s layout. The Gateway, using the RIP protocol, determines the network packets’ route
based on the fewest number of hops between the source and the destination. The RIP protocol regularly
broadcasts routing information to other Gateways on the network. To enable RIP, click
Enabled
. To disable RIP,
click
Disabled
.
•
Transmit RIP Version. To transmit RIP messages, select the protocol you want:
RIP1, RIP1-Compatible, or
RIP2
. If you don’t want to transmit RIP messages, select
None
.
•
Receive RIP Version. To receive RIP messages, select the protocol you want:
RIP1
or
RIP2
. If you don’t want
to receive RIP messages, select
None
.
Static Routing. To set up a static route between the Router and another network, select a number from the Select
Entry drop-down list. (A static route is a pre-determined pathway that network information must travel to reach a
specific host or network.) Enter the information described below to set up a new static route. (Clicking the
Delete
Entry
will delete a static route.)
Destination IP Address. The Destination LAN IP is the address of the remote network or host to which you want
to assign a static route.
Subnet Mask. The Subnet Mask determines which portion of a Destination LAN IP address is the network
portion, and which portion is the host portion.
Gateway. This is the IP address of the gateway device that allows for contact between the Router and the
remote network or host.
Hop Count. This determines the maximum number of steps between network nodes that data packets will
travel. A node is any router in the path to the remote network.
Interface. This interface tells you whether the Destination IP Address is on the
Local
(Ethernet and wireless
networks) or the
Internet
.

The Wireless Tab - Basic Wireless Settings
The basic settings for wireless networking are set on this screen.
Wireless Network Name (SSID). The SSID is the network name shared among all points in a wireless network.
The SSID must be identical for all points in the wireless network. It is case-sensitive and must not exceed 32
characters (use any of the characters on the keyboard). Make sure this setting is the same for all points in your
wireless network. For added security, you should change the default SSID (linksys) to a unique name.
Wireless Channel. Select the appropriate channel from the list provided to correspond with your network
settings. All devices in your wireless network must be broadcast on the same channel in order to function
correctly.
Wireless SSID Broadcast. When wireless clients survey the local area for wireless networks to associate with,
they will detect the SSID broadcast by the Router. To broadcast the Router's SSID, keep the default setting,
Enabled
. If you do not want to broadcast the Router's SSID, then select
Disabled
.

Wireless-B Broadband Router
The Wireless Tab - Wireless Security
The Wireless Security settings configure the security of your wireless network. Click the radio button next to
Enable
to enable Wireless Security before choosing your options. Click the radio button next to
Disable
if you
need to disable Wireless Security.
There are four wireless security mode options supported by the Router, WPA, RADIUS, and WEP. These four are
briefly discussed here.
WPA Pre-Shared Key. WPA provides the TKIP encryption method, with dynamic encryption keys. Enter a Pre-
Shared key of 8-32 characters, and enter a Group Key Renewal period, which instructs the Router how often it
should change the encryption keys.
WPA Radius. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS server is
connected to the Router.) Enter the RADIUS server’s IP Address and port number, along with a key shared
between the Router and the server. Then, enter a Group Key Renewal period, which instructs the Router how
often it should change the encryption keys.
Radius. WEP used in coordination with a RADIUS server. (This should only be used when a RADIUS server is
connected to the Router.) First, enter the RADIUS server’s IP Address and port number, along with a key shared
between the Router and the server. Then, select a level of WEP encryption, and either generate a WEP key
through the Passphrase or select a WEP key and a enter the WEP key manually.
•
WEP Encryption Level. An acronym for Wired Equivalent Privacy, WEP is an encryption method used to protect
your wireless data communications. WEP uses 64-bit or 128-bit keys to provide access control to your
network and encryption security for every data transmission. To decode data transmissions, all devices in a
network must use an identical WEP key. Higher encryption levels offer higher levels of security, but due to the
complexity of the encryption, they may decrease network performance. To enable WEP, select
64 bits (10
hex digits)
or
128 bits (26 hex digits)
. To disable WEP encryption, keep the default setting,
No Encryption
.
•
Passphrase. Instead of manually entering WEP keys, you can enter a passphrase. This passphrase is used to
generate one or more WEP keys. It is case-sensitive and should not be longer than 31 alphanumeric
characters. (This Passphrase function is compatible with Linksys wireless products only and cannot be used
with Windows XP Zero Configuration. If you want to communicate with non-Linksys wireless products or
Windows XP Zero Configuration, make a note of the WEP key generated in the Key 1 field, and enter it
manually in the wireless client.) After you enter the Passphrase, click the
Generate
button to create WEP
keys.

•
Default Key. Select which WEP key (1-4) will be used when the Gateway sends data. Make sure that the
receiving device (wireless client) is using the same key.
•
WEP Keys 1-4. WEP keys enable you to create an encryption scheme for wireless network transmissions. If
you are not using a Passphrase, then manually enter a set of values. (Do not leave a key field blank, and do
not enter all zeroes; they are not valid key values.) If you are using 64-bit WEP encryption, the key must be
exactly 10 hexadecimal characters in length. If you are using 128-bit WEP encryption, the key must be exactly
26 hexadecimal characters in length. Valid hexadecimal characters are “0”-“9” and “A”-“F”.
WEP. WEP is a basic encryption method, not as secure as WPA. To use WEP, select a level of WEP encryption, and
either generate a WEP key through the Passphrase or select a WEP key and a enter the WEP key manually.
