Hello, I bought the acer desktop model ATC-605-UB12 a few days ago. It comes with a built in wireless card and connects to my wifi no problem. but after its connected and being used for 5-10 mintues my wifi speed drops to 0. Still shows its connected with full bars but no wifi speed at all. All my other devices connected to my netgear router work perfect during all this. I contacted acer and they had me reinstall the network adapter drivers and still had the same issue. I went back to best buy and exchanged it for another and i'm still having the same issue. Any help woukld be greatly appreciated thanks guys!
