i have a wrt54g linksys router and one wireless desktop pc with a linksys card. i enabled 128 bit WEP. i also have the option on my router setup screen to use WPA which from what i understand is more secure. i dont think WPA can be configured on my wireless card,or at least i cant find where, just WEP. I have just the 2 pc's on the netowrk using windows xp home and a cable modem. do i need something else to use WPA? driver update for the card or something? or something else? is WEP fine for my network--only 2 PC's, not really any super sensitive data or anything. I just figure i should use WPA if it is more secure but what do I have to do to use it?
