This is my setup: WRT54G 4 Port Wireless Router v 2.2. Connects to one PC via ethernet Connects to second PC via Wireless Network. The second PC is currently running a new Linksys Wireless G PCI Card. (RT2500 Chipset version). If I setup my network using WEP security, and set a key for that, there are no problems. However if I use a WPA Pre-Shared key, the PC will see it, link up, and connect. After a reboot however it can no longer find the network. Even if I refresh it through Windows Wireless Zero Config or the Linksys software. Both will come back as "Network not found" "No networks" etc. Same if I uninstall the software/reinstall and reboot. It seems the network will NOT appear unless I go into the Routers setup page again, and change the channel. I will then get a connection again to the network, until I reboot. IF i change the network security to WEP it will work fine again and remember the settings. So the problem seems to be with WPA security. I am also using Sveasoft linksys' firmware. Not sure if that makes a difference. Thank You!
