Hi there, I'm in the UK and I successfully set up my Linksys WAG54G ver2 wirelessly connecting to my desktop PC (with Linksys WUSB54G network adapter) running Windows XP (Home service pack 2) using the suggested WEP security. I have ZoneAlarm (ver6) and use the modem-routers firewall. I read about a better security system called WPA-PSK which my modem-router and adapter can offer. I connected WAG54G to PC using ethernet cable (I read that this was the best way to set up the device ?) and amended the settings - thereafter altering the adapter settings also. Nothing worked! I was unable to connect to the internet. So I reset everything and have gone back to using WEP. Everything works fine. I am very much a newcomer to wireless networking. Any suggestions to what I did wrong - I believe WPA-PSK is more secure and would prefer that setup. Many thanks.
