My mate has a airlink card he got from Frys. It was working fine in his previous machine, but just built a new rig. Problem is, when he installs the card, the computer goes full load and the cpu usage never dips below 80% plus the internet is slow as balls. I thought maybe it was firmware, tried an older version, but no aval. Tried using windows utility but no go. So I thought it could be the new crappy ECS mobo, swapped my gf's sister's netgear and works like magic. Popped the airlink one into hers and same situation on her computer. Im stumped, wtf can it be? Can it be the IRQ? If it is, how can i change it? Thanks guys.
