I need help pls

I own a Lenovo X230 ... I had windows 7 the wifi icon used to disappear and wifi card disappear from device manager and show up as unkown device.

Sometimes wifi works sometimes it doesn't ... Till it stopped.

I downloaded drivers from lenovo ... It worked and then stopped again.

Decided to install windows 10 ... Wifi Worked ... after couple of days ... It stopped again.

Only Ethernet cable always works.

What should I do?

Updated latest drivers through Windows 10 updates. Doesn't help.
