WIFI Wont Turn On!!!

[Bánh mì]

I have an Intel WIFI card in my X201. Last week I was setting up a new Internet connection on WIFI. Got impatient I think as it wasn't connecting so I turned off the WIFI manually thinking would just turn it back on. Haven't been able to despite the switch is in the on position. I did a search online and on this site and tried all things:
1) Uninstalling Access Connections/Reinstalling
2) Uninstalling WIFI card drivers.
3) Using Intel's latest drivers
4) Uninstall Power Management/Reinstall
5) Soft reset BIOS with F9 key to defaults

When I hit the FN F5 key I can see my Bluetooth, WIMAX and WIFI. The WIFI is the only thing I cannot turn on or off.

Windows and Intel Diagnostics tells me I have a WIFI problem but they cannot fix it when I select the buttons. Something about driver not binding to TCIP (over my head) I saw.

Can you help? About to reformat. Lenovo support was clueless. Offered new WIFI card but I don't think it is the problem.

PS One option I read about was to pull the CMOS battery. I guess that would be a hard reset of the BIOS but I don't want to resort to that. Will reinstalling Windows fix this?

I determined this stems from the latest Lenovo version of the Intel WIFI card drivers. Don't install it. I hard to do a repair install twice to get things going again. Lenovo should check their drivers. Seems the installer is different and there is an issue with removing the old conflicting with installing the new. And results in some Net Framework 4.0 issues. Its a total disaster.
