Hi Maestro1980, Welcome to the forums, Have you set the power management for the 5100n ? They don't appear to handle this very well
-Right click on Computer and select Manage.
-After Computer Management opens up, go to Device Manager.
-In Device Manager, expand the Network Adapters category.
-Right-click on “Intel (R) WiFi Link 5100 AGN” and select Properties.
-In Properties, go to the Power Management tab.
-Under the Power Management tab, make sure that “Allow the computer to turn off this device to save power” is unchecked.
Apparently, the driver for the WiFi Link 5100 can’t properly handle the device going to sleep, and pulls down the whole system.
