In device manager, network
Your wireless adapter, uncheck the box, allow the computer to turn off to save power.
Do NOT uncheck the boxes under Microsoft Virtual Miniport adapters.
In Device Manager I find:
Network Adapters, Intel(R) Centrino(R) Wireless-N1030, Properties, Power Management and find "Allow the computer to turn off power to this device" box is already unchecked.
So I'm still looking for a solution.
The boxes can be unchecked for all of them except...
Microsoft Virtual Miniport adapter
Microsoft Virtual Miniport adapter#2
The Microsoft Virtual miniport adapters need the boxes check, or they go missing.
After more expermentation I find that the problem occurs every time the computer goes to sleep.
If I reboot WI-Di works flawlessly.
As I mentioned previously, "Allow the computer to turn off power to this device" box is already unchecked.
Is this normal that one must reboot the computer to restore functionality once the computer entered nthe sleep mode and thereby enable the Intel Wi-Di function to operate?
Or is there a way to set it up so that Wi-Di will still operate after the pc has taken a nap (without a reboot)?
