Netbook keeps diabling wifi card
Backstory: I have a cart with 30 netbooks in one of my middle schools. These netbooks ran Vista x86. We are now in the process of upgraded all of our win2k and vista up to Win 7 x86. I imaged half of these netbooks last week. There is about half Dell 2110s and the other half is MSI Wind U160s. Both models of netbooks keep disabling the wifi adapter. Under the student account they cannot go into the network sharing center to re-enable it. At first I thought it was a power management issue and the adapter was just not waking up. Since then I have reinstalled the latest drivers, unchecked turn off this device to save power, and set the power management GPO to never put the netbooks to sleep. None of those have helped.
Once re-enabled the will work for the rest of the day. It's not all the time either, the one netbook worked for 3 days and all of a sudden today the wifi card was disabled again.
Any ideas? Thanks
