T500 Windows 7 Wifi Connectivity/Missing Drivers

2011-07-04, 23:04 PM

A few days ago, my T500 (Windows 7 Ultimate, 32-bit) crashed and went through a startup recovery process. When it was finally logged into Windows, I was unable to detect or connect to any wireless networks and Google Chrome (my primary browser) was gone.  After I couldn't find any restore points when running Windows Restore, I decided to just manually restore the missing components. I was able to connect to the internet via ethernet and reinstall Chrome (albeit missing all of my bookmarks and plugins), but still had issues with the wireless connection. Windows Network Diagnostics returned "There might be a problem with the driver for the Wireless Network Connection adapter," but was unable to troubleshoot the issue.

 

Windows Device Mangager showed no missing network adapter drivers, but under "Other devices" each of the four items were missing drivers:

  • Base System Device (x2)
  • PCI Serial Port
  • PCI Simple Communications Controller

I've downloaded a number of drivers, (including several variants of Inter AMT and the Multi Card Reader, as suggested by similar threads), but none have addressed the four missing drivers. All attempts to update the drivers were unsuccessful.

 

  1. Could the missing "Other devices" drivers be causing my wifi issues? 
  2. Are there drivers I can update them with? 
  3. Is an updated driver available for the wireless network adapter (currently 12.4.1.4; none of the downloads have updated it)? 
  4. Is it possible to recover my data from the old installation of Chrome without any backups or restore points? (obviously I should have been backing up my data)

 

Thanks.

Try System Update... The latest driver for the 5100/5300 adapters is 13.5.06.

Not sure why Windows would nuke your Chrome profile, though. Chrome does tend to put things in weird places, so I'm not too surprised.

I've tried System Update a few times. It never updates the driver past 12.4.1.4. Is there a direct link for just the driver? (The update is always like 85 mb).

Try this:

I can't find the driver on the Lenovo site either...

Re: T500 Windows 7 Wifi Connectivity/Missing Drivers

I downloaded and attempted to install the driver a few times, but the installation failed each time. I also tired uninstalling the current 12.4.1.4 driver, but the installation still failed, and Windows update just reinstalled the old driver. Is there a way I can completely remove the 12.4.1.4 driver so Windows won't try to use it again?

Any thoughts on the other missing drivers?

When I try to manually update the driver using the the link you sent, Windows start the installation, but stops and gives this error message:

"Windows found driver software for your device but encountered an error while attempting to install it."
"Intel(R) WiFi Link 5100 AGN"
"The specified procedure could not be found."

Windows isn't allowing this driver update (or any of the others; they get similar "procedure" errors).

Sounds weird. Make sure your Windows 7 is actually 32-bit; the link I sent should be 32-bit.

Also, try running SFC /SCANNOW from an elevated command prompt to see if any system files are corrupt.

Re: T500 Windows 7 Wifi Connectivity/Missing Drivers

I ran sfc /verifyonly and sfc /scannow; it said there some corrupt files and to check CBS.log. The file was fairly long, and I couldn't really discern any relevant information from it. Ctrl-F didn't find anything related to the driver. I don't know what, if anything, was fixed, but the driver issues still remain.

 

I've tried to manually delete the old 12.4.1.4 drivers with no sucess. Even as an administrator in safe mode, I still couldn't modify anything. SYSTEM and TrustedInstaller are listed as having full control over the files, and there was no option to change the permission settings (check boxes were grayed out). 

 

Is there anyway to modify those permissions so I can delete the old drivers? Would it helpt to reinstall 12.4.1.4? I've looked for a download online but haven't found anything yet. The only other solution I can think of is reinstalling Windows 7. Does that sound like the right course of action? The wireless card and the other drivers haven't had any issues up until now. It seems like some system files were corrupted when it went through the startup repair that started all of this.

 

Thanks
