Gateway M280 classifies all network adapters as "Unknown Devices".
Posted on 2008-10-06
In the shop we have a Gateway M280 Convertible Notebook PC. It had a bad motherboard so it was replaced with an identical model motherboard. The problem is a lot of devices had to have their drivers reinstalled, which wasn't a problem except for one section, Network adapters.
All network adapters on the system show up as an "unknown device". This includes the 1394 net adapter, the integrated Broadcom ethernet, the Intel 2200 wireless module, and two different USB to ethernet adapters.
Any adapter that has to do with networking immediately is classified in the "Unknown devices" category. We have tried reinstalling drivers, and while they install correctly it still classifies it as an unknown device. We have tried uninstalling the device and that doesn't work either. So far this only happens with Ethernet devices. What could be wrong?
