Question “No WiFi adapter found” after Ubuntu 18.04 update

[gordonfreemanjr]

After the latest update (2020/01/17,18), not a clean install, there's "no WIFI adapter found" on my Ubuntu 18.04. The machine is a Win 10 dual boot Lenovo IdeaPad L340. Secure Boot is off (it was before the update, it stayed off after).

What do I do?

Hi

Did it ask you to reboot the laptop after Ubuntu updated?

On the desktop type drivers in the text field than open additional driver have it do a scan see if it finds the drivers for the card. If this fails than please post the output of this command

sudo lspci -v

I have no idea what the reason was, but this guide helped instantly:
