Windows 7: Win 7 cannot see wireless networks

Hello I am having a problem with windows not letting my wireless adaptor see any networks. Ive gone into device manager and everything checks out ok no issues. Checked out my adaptor settings and it shows that its up and running but I cant scan for networks an the icon in the lower right shows a red x on my connections. I know the hardware is good. I swapped drives with a back up and reload windows and everything works fine. So i know the hardware is ok. I have removed all antivirus and firewall programs. Is there some hot fix or whatever because I really dont want to reconfigue everything again.

Go back into Device manger and Reinstall the Drivers for your Network adapter then Restart your computer and it should reinstall the Drivers ,

Sometimes Windows reports that the Drivers are Okay but they aren't

Hope This Helps,
Josh
