I do understand why you may not want to reinstall... Sometimes there is no other way. could be bios issue, i suggest trying another wireless card. The drivers for that card and Windows 7 are currently fighting.
Just in case anyone else finds this page trying to fix this...
do the following:
Go to windows services control panel (Start > Run > services.msc)
Find the "WLAN AutoConfig" service. Set the service start mode to "Manual" or "Automatic". then start the service.
IF the service is in disabled start mode, windows diagnose and repair may not be able to fix it...
I had the same problem with my new Edimax EW-7722In card. The solution (thanks to Edimax technical support, to give credit where it's due) was to disable the self-defence mechanism in Kaspersky by unticking the relevant box. That done, I then removed the driver etc via Device Manager and reinstalled from scratch. It worked!!
We had previously tried the "WLAN Auto Config" solution recommended below but this did not work for me.
I hope this works for others.
