Four keys will be generated. Choose a key ID (1-4) from the 
drop-down list or accept the default key.
If you use encryption, configure the same keys used for the 
Router on each of your wireless clients. Note that Wired 
Equivalent Privacy (WEP) protects data transmitted between 
wireless nodes, but does not protect any transmissions over your 
wired network or over the Internet.
WPA
Wi-Fi Protected Access (WPA) combines Temporal Key Integrity 
Protocol (TKIP) and 802.1x mechanisms. It provides dynamic 
key encryption and 802.1x authentication service. With TKIP, 
WPA uses 48-bit initialization vectors, calculates an 8-byte 
message integrity code, and generates an encryption key 
periodically. For authentication, it allows you to use 802.1x 
authentication for an environment with a RADIUS server installed 
on your network. Selecting the Pre-shared Key enables WPA to 
use the pre-shared key in a SOHO network.
