Please help me, my wifi station works on my notebook (windows vista!!!) only 4-6 minutes, then wifi not available on notebook. I reboot my wifi, wait about 15 minutes and then wifi works on note about 4-6 minutes, then next and next... Whats the problem? I have installed 9 version.
uhm... well...
did you test it with a different wifi client?
and did you modified the advanced wireless settings? these are quite sensitive, I tried it once and broke it:p to reset all the values you need to set back to the factory defaults.
also: old drivers for intel wireless chipsets in laptops have problems with WPA2... so you might update drivers if so:)
-does it also happen if you are close to wireless router?
-try different wifi channels (fixed). there could be interference from your neighbours.
