Re: Yoga 2 wifi not working after update to Windows 10

2015-07-31, 17:47 PM

I had the Cisco vpn installed. Have rolled back to win 8 and uninstalled the Cisco vpn. Now installing windows 10 to try again for the 6th time. Have also turned off fast boot in the power settings so that the laptop does a full shutdown. Will report back once installation is complete. 

 

UPDATE

 

Ok, finally got it working. Believe it or not, it was a simpe shut down like everyone has said which fixed it. However, ti wasn't just a regular shutdown which I used. I followed the steps in this article to turn off fast start-up, and then shutdown the laptop through the normal power option in the start menu.

 

http://www.windowsten.info/content.php?23-How-to-fully-shut-down-windows-10

 

There are two methods for the full shutdown. I followed the second method which involved changing the fast start-up to off. After turning the laptop back on after the shutdown, I turned the fast start-up back on and it seems to be working fine.

 

Hope this helps others who are having the same issue.

Hi guys,

 

I solved the problem by going to Device Manager and rolling back the wifi driver to the 2013 version. It worked like a charm and I'm typing from my Lenovo right now! If this works for you, please kudos this message so others can give it ago. Cheers.

I was having this wifi issue and it turns out that it was due to Cisco VPN (and other VPN software) which has been causing wifi problems in Windows 10. If you have Cisco VPN (or other VPN software) then you should uninstall before upgrading windows.

 

To fix the issue I rooled back to 8.1 (ony take 5 minutes if you still have the windows.old files). Then uninstalled Cisco VPN, then reinstalled windows 10 and my WiFi works perfectly.

 

You can also try this solution which has been shown to work without reverting back to 8.1 but I didn't try it.

Just another datapoint here:

  • I've also got a new Yoga 2 13
  • I've got VPN software installed, in my case Juniper's Junos Pulse
  • Updated from Windows 8.1 to 10
  • No wifi, no way to enable it
  • Rebooted ('soft'), didn't help
  • Came to this thread
  • Tried the hard reboot, as in 'hold the power button down for 10 seconds'
  • Booted the machine again, problem solved

Re: Yoga 2 wifi not working after update to Windows 10

I have a Yoga 2 pro as well. I have tried everything on this thread, new drivers, everything but nothing works. It is even worse now as I keep losing the wireless connection . I am using a tablet now to type this out as the computer is not usable.

 

A fix from Lenovo would be appreciated. I had no VPN set up in my computer.

Have you run "Troubleshoot problems"?  Right-click on the network icon on your taskbar, and select it.  What is the result?

I'm not sure if all Yoga 2 user with wifi problems on upgrade had some form of vpn (in particular Cisco ones) but that was my case.
To solve use you have to revert back to Windows 8, uninstall the vpn and re-upgrade. A bit painful but worked.
