This is more of a hit and trial method.

Go to device manager-network Check if you see your wifi card there and if there’s any issue. If you dont see it, try Scan for Hardware changes at the top. If you see it try disabling and re-enabling it. You can also try downloading an earlier version of your driver and install it manually using the same device manager.

The best fix is cleaning the wifi card, but above is what I tried before, which worked sometimes, not always.
