Windows 7: WIFI only connects after running troubleshooter....


07 Feb 2013   #11

Windows 7 Home Premium x64
 
 

I booted my computer in safe mode with networking. I saw the machine trying to connect but it did not. When I clicked on the network icon to try again, no networks were visible.

Most likely a driver problem in that case but I'm curious, which wireless security and encryption are you using?

Your router should be set to use WPA2 with AES encryption.

It may help to remove the wireless profile for this connection then create a new one that defines the same settings as your router is using.

I have just checked the router settings.

It is using WPA2-PSK (Wi-Fi Protected Access with Pre Shared Key) with AES encryption.

How would I remove the wireless profile etc. as you suggest?

Just go to the Network and Sharing Center, look to the left side where it says "Manage Wireless Connections"

Remove the old profile and make a new one with the proper connection details and see what happens.

I've also noticed that you don't have the Microsoft Virtual adaptor installed, this adaptor installs with all Windows 7 approved wireless drivers.

Because the Msoft virtual WiFi adaptor isn't installed it indicates this Broadcom driver is not Windows 7 approved.

I would suggest you look around for a Windows 7 approved driver, maybe Windows update or the Lenovo site.

If that link isn't the same model use this one.

Removed connection profile and replaced as per your instructions.

Unfortunately it has made no difference.

Onto the drivers!

I download the driver from Lenovo. When I install it tells me the file is already present on the system do I wish to overwrite and I click yes to all. I then get error message " The operating system is not supported. The software will not be installed. Setup will now exit". I can now find no trace of the driver on my system, no Wi-Fi at all. I have had to plug laptop into the router with a cable. Help!

Got the driver reinstalled thankfully but still no change to the issue.

That driver isn't approved so no wonder it's causing you problems. Typical Lenovo.

It may help to get the driver from Broadcom directly or Windows update may have it.

Trying to find it on the Broadcom site now, easier said than done.

A question, on my device manager when I check the driver, it says it is provided by Microsoft? Aren't you saying it isn't hence causing the issues?

Not sure if this is relevant.

Again in Device Manager, driver file details lists two files.

One is a Broadcom file, the other a Microsoft file.

Also do you have any idea what to look for on the Broadcom site, I enter the details you would expect and get lots of hits to stuff I don't understand.
