iMac G5 WiFi "Connection Timeout" Problem

[jiburden]

I have an iMac G5 running OS 10.5.6 that I want to add to my home network. It will share a network with a new iMac, a Macbook, and a PC. This all runs off a Time Warner Router and all the Wifi connections work great except for the G5. It will pick up the router signal (router is in the same room), but when I enter the password, it works for a bit and then says "connection timeout" or occasionally "invalid password. The security setup is WEP Password. My WiFi network is fine - so what do I need to do to make the G5 play along? Thanks!

Connect it via ethernet and do a software update. After updates install, try it again.
