Both our computers are running on XP, had the limited connectivity issue but got around that by using wpa-psk with tkip but when more than one pc is connected, both will work good for a minute or two, then one will not be able to surf. (whichever one connected second) "page cannot be displayed" etc. Both will still have excellent wifi signal since everything's in the same room. Thought they might be fighting for the same IP address so I assigned one with 192.168.1.3 and one with 192.168.1.6 but that didn't help. Any suggestions aside from buying new laptops with win7?
