Microsoft Virtual WiFi Miniport Adapter does not work anymore after wake up from hibernate

Hi all!

I have a Dell Studio Laptop 1737 with Dell Wireless 1397 WLAN mini-card and Windows 7 home premium 64 bit. Some days ago, I bought a HP WiFi mouse (model LQ083AA). This mouse connects via WiFi and you need no USB-port for a transmitter. Very practical - if it would work probably.

First I installed the SW delivered with the mouse. During this installation, also the "Microsoft Virtual WiFi Miniport Adapter" was installed. The mouse connects via this adapter. And everything worked fine. The mouse was found, a connection was established and the mouse worked like a charm. Until I went to sleep. As usually, I hibernated the notebook. And after waking up the notebook from hibernate, the mouse did not work anymore. I found out it is because the "Microsoft Virtual WiFi Miniport Adapter" does not wake up correctly. After a reboot, everything works again. And if I use the HP software to reestablish the connection, I receive the error "SoftAP is not available".

I tried several things:

• I un-installed the "Microsoft Virtual WiFi Miniport Adapter" in the device manager and checked for new HW to install it again. But after it was installed again, it still did not work.
• In the device manager, I disabled "Microsoft Virtual WiFi Miniport Adapter" and enabled it again - but it stayed disabled.
• I updated the driver.
• I changed energy management, allowed the computer to switch of power of the adapter resp. disallowed that.

Nothing I did helped. After hibernate, the "Microsoft Virtual WiFi Miniport Adapter" is "dead". Only a reboot helps.

The WiFi mouse is such a great Idea, but the "Microsoft Virtual WiFi Miniport Adapter" is such a mess.

Can someone help here?

Thanks,
Claus
