For some reason, while I am able to connect to a network via an Ethernet cable, I'm currently having difficulties with wifi.

I do not have an option for a wifi connection even though if I type lspic in terminal, it does display the Broadcom BCM4322 wifi adapter.

I also typed in the sudo nmcli r command and it states the wifi-hw, wifi, wwan-hw and wwan are enabled. Yet only enp0s10 is the only network device available for use.

Some assistance would be appreciated.

Maybe I am wrong about this, but you can try "additional drivers" by Ubuntu (KDE Neon is ubuntu under the hood) and install driver for Broadcom wifi...

I am not sure, but "additional drivers" app should be "jockey-kde" or "jockey-gtk".

Take all of this with some caution because I am not using K/Ubuntu for very long time.

If You have this:

Code: Select all

$ lspci -vv -s 03:00.0

Well this somewhat worked in the sense I got wifi to work, but also broke the whole OS since I have a full drive encrypted. Gets stuck in the decryption startup page or a black screen.

I take it I shouldn't have used autoinstall?
