wireless service can't start

Hi!
My wireless stopped working, I'm with win7 x64.
1. I go to services, try to start WLAN AutoConfig but Error 1068 appear - "Windows could not start the WLAN AutoConfig service on Local Computer. Error 1068: The dependency service or group failed to start."
2. I read some forums and went to regedit.exe>HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>services>Ndisuio
and my "Start" value is 3, not 4, it should me OK but it's not.
3. I've also run "sfc/scannow" from cmd, and no errors.
Nothing helps...
Please if someone has ant clue how to fix this help me!

I've just fount out that some services are missing, how can I put them back on the list and start them?

I copied the necessary reg files form my friend's PC, everything is ok now. Thanks.

I have the same problem, but the solutions above are not working at my computer. Do you have other tips!

I have tried the three steps of onopko, but the this not helping to my computer. On advice of StalkeR I have add the reg files of Black Viper site as Safe as well default. Every time I have restarted my computer after adding the reg files, but both files are resolving me problem.

After these steps I have exported the reg data of (I belive that this was the solution of onopko)HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>services>Ndisuio. The export is been done from working WIFI laptop. The reg data is been imported into my computer, but didn't help also not!

Strange of my computer is that I have twice the service WLAN Auto-Config. But both services are getting the same error-message. Can somebody help me with this problem?
