I have a Pavilion a6700y machine that a customer brought me, Vista 64-bit. It is having trouble with the network drivers for the onboard LAN card and aftermarket WLAN card. I have uninstalled the hardware, deleted drivers, and loaded fresh drivers from respective sites. I have added an additional NIC and USB Wireless device, but they present the same problems. I believe the issue was caused by a virus that the customer removed themselves, but I cannot find anything to help fix the issue.
Anyone seen this before? How did you get it resolved?
