Cannot connect to a wireless network used previously
If you are unable to resolve the issue of a wireless connection that worked previously but does not work now, performing a system restore may be the final option. Microsoft® System Restore, if set up to do so, will create restore points automatically and periodically. Use an existing restore point to return your system to the condition it was in when the wireless connection worked.
