I've just been through the latest two pages of Networking and I can't see your thread, which might explain the lack of a decent answer, no? ;-)
Steps to check:
1) Enter Device Manager and look for your wireless LAN adapter. Is it installed properly? Is it reported as functioning?
2) If that's okay, look in Services (run services.msc) and look for the status of network-related services such as SSDP, Plug-n-Play, NLA, etc.
