Windows 8.1 wi-fi connection problems

I upgraded my tablet (Lenovo ThinkPad Tablet2) to Windows 8.1 and can no longer connect to Wi-Fi networks. I've done all the diagnostic stuff: reset the network adapter, etc. I checked the Microsoft forum and this seems to be a problem.

One data point:  Had the the same problem. Updated drivers through Windows update and turned off IPv6 from wi-fi network and other network adapter properties. And it worked.

Any devices with a yellow exclaimation mark in the device manager?

As aadih suggested above a thorough Windows Update paying particular attention to drivers in the optional category will fix most issues.  The 8.1 upgrade invalidates a lot of drivers I've found.

Also, if you see any network adapter with the word "multiplexor" in it, disable it if you can.  Then right-click on your wi-fi adapter and make sure it's not bridged.  If it is bridged, remove it from the bridge.

All devices are ok. No updates to install AND Wi-Fi is now working. Who knows why and how long it will last. What's the easiest way to temporarily disable IPv6 in Windows 8.1?

No multiplexor, no bridges. Now that the Wi-Fi seems to be working, I'm going to try it out on several different networks.
