We bought a new router because the old one broke. We have 8 computers connecting to a router using WPA-PSK (It is a Belkin wireless N router). 1 of the computers that could connect to the old router using WPA is now throwing a hissy fit. It can connect fine as long as there is no security feature turned on (WPA1 or 2) but has "limited to no connectivity" as soon as we turn on WPA. Of course I've done the standard thing of checking that the protocols match (i.e. WPA1 on both devices, TKIP or AES encription match). It is leaving me a bit clueless. I swear at one point the laptop was connected even though WPA was on, so it is possible in principle, but after a restart all connectivity was lost again. It asks for a password, then tries to log on for over a minute and then says that there is limites or no connectivity. All other computers are connecting just fine.
It is making me want to pull my hair out.
