wireless is not very good for playing AH to begin with. If you can, wire your computer to your router that would be the best solution as far as game play goes. I would go to the device manager, click network adaptors, and right-click the wireless adaptor and choose properties. It should say "this device is working properly". Try to disable the adaptor and then enable it. If you need a new card just check the location of your current card (in the properties) and order a new one from newegg with the same interface (ie pci, pcie, usb, etc)
