Wireless-B Broadband Router
WPA Pre-Shared Key. If you do not have a RADIUS server, select the type of algorithm, enter a password in
the Pre-Shared key field of 8-64 characters, and enter a Group Key Renewal period time between 0 and
99,999 seconds, 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.) First, select the type of WPA algorithm. Enter the RADIUS server's IP
Address and port number, along with a key shared between the Router and the server. Last, 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 WEP key and a level of WEP encryption, and either
generate a WEP key through the Passphrase or enter the WEP key manually.
Implementing encryption may have a negative impact on your network's performance, but if you are transmitting
sensitive data over your network, encryption should be used.
These security recommendations should help keep your mind at ease while you are enjoying the most flexible
and convenient technology Linksys has to offer.
