Mint 19.1 Wifi no longer lists available networks

[bjku]

Hi
My Wifi no longer lists available networks. This is a sudden change
It works with the installation disk. I tried to reinstall Linux Mint 19.1, but it still doesn't detect.

Any steps I should take to solve this?

Thanks

See if there's a wifi switch or Fn/F key that may be off.
Turn Secure Boot off in Bios, if it got turned on.
