I have a Dell XPS1645. I recently did a complete Windows 7 (ultimate) reinstall and went through updates through SP1 and successfully reinstalled all other software, etc. and, well, things were pretty good again. Wireless networking was perfect and I then installed some home media software. I was, and am still, connecting to my wireless router and serving media files via wireless off my XPS1645 PC.
Please see notes, below, as to my CURRENT configuration in regards to Intel support on my PC.
Unfortunately I ran into a "My WiFi" problem, which is, I guess now, a secondary issue here. I carefully updated to Intel® WiFi Link 5300 184.108.40.206. Wireless was working well. All Intel tests passed. However "My WiFi" was not working with a message that "no supported adapter was found". I was unable to click "options" or anything else in the My WiFi console with that message. Via Googleing and here I was unable to find any help with this error message. Still, all Windows 7 functions like list of wireless network connections and facilities available through the Network connection and sharing center were available.
Left again to nothing else but the futility of trying uninstall/reinstall on Windows, I gradually "rolled back" as I could. Unistalling/reinstalling WiFi Link 5300 220.127.116.11 didn't do it. Finally, back as far as I could go I reinstalled Network: Intel Intel Intel(R) WiFi Link 5300 DRVR Version : A00 for Studio XPS Laptop Studio XPS 1645 Windows 7 64-bit from the Dell drivers installation CD.
After reinstalling A00 my Windows 7 user interface functionality was broken, That is, the list of wireless networks never appears in the popup from the Network status bar icon and no wireless network appear in the mange wireless networks link from the Network and Sharing page and no wireless connections appear on the Network Connections page. Now diagnostics don't get past the hardware test. However my wireless is there and working!
Please, I have exhausted trying tricks though the Windows 7 Control Panels, etc. I found no 5100/5300 files on Intel website that helped. A WiDi update that might have been useful failed due to my hardware configuration. From googling it seems no one else has this problem. I can't find anything on Windows 7 similar to the XP "ZeroConfig" installation. System restore prior to reinstall of the original driver fails saying a "file is missing".Windows system restore gives NO information as to what that file is except to say that a virus scanner probably caused the failure, which it did not (how many times do we get LIED to?). I find I can not do a Windows 7 repair install being told I now have a version higher than the repair install version to be upgraded to.
Is there someone out there with the solution to this problem?
