I am having a similar problem but my wireless was working for some time and suddenly stopped. I have tried many different ways to try and fix this problem. Enabled/ disabled the network adapter as well as uninstalling and reinstalling the newest driver, restarted the comp, restored to the earliest restore point, removed all ghosted forms of usb devices (these apparently show up if you dont always use the safely remove hardware) i have checked in device manager-all network devices are installed up to date and have no icons beside them, i can access the internet from the laptop and from my ipod with the same settings that i have on the desktop but the desktop wont connect. I have used the trouble shooter to no avail, my desktop can see that connections are available but it just wont bloodly connect. I have tried this :
