Okay, so I have a cheap tew-643pi wireless card and I have had nothing but trouble with it. It’s biggest problem is online gaming. It sometimes worked perfectly and other time not at all. I recently switched from my old internet, at&t broadband, to comcast (which is well over twice as fast) and now it works okay for regular web browsing but it can’t play online games at all. Modern Warfare 2 is completely unplayable. Other games like L4D2 are playable, but go between 100 to 1000 ping. What could be wrong??? Also, the drivers are up to date.
I also switched routers to a DIR-655 d-link router if it could be the problem.
I had problems with my last wireless card as well; it caused my computer to stutter. I gave it to a friend and it’s been working fine on his computer but I don’t see how it could be a problem with my comp as I tried switching the pci slots and make sure it was mounted correctly and everything.
