Ubuntu 20.04.2 LTS not connecting to wireless (wifi)
I messed up something badly. My system did not have a settings menu, which happened because I had added the ppa:system76/pop repository, installed some things, then removed this repository. I tried to apt install gnome-control-
Then I did sudo ppa-purge ppa:system76/pop. Halfway through this as it was unpackaging, it popped up an alert suggesting I abort, because it was about to remove the currently active kernel. So I aborted and it ended with an error. Then up popped the software updater to install a different kernel version, so I allowed that to go through. Then it said it needed to restart, so I allowed it to restart. Bad mistake. It did reboot, but without a wifi connection.
There is no settings menu that shows wireless network options. I went through the official Ubuntu pages, but it didn't address this situation.
From the terminal command line:
lspci shows Network controller: Intel Corporation Wireless 7260 (rev 73)
iwconfig shows lo no wireless extensions
lshw -C network shows *-network UNCLAIMED for both network controller and ethernet controller
nmcli shows device lo, type loopback, state unmanaged, connection --
Any ideas? I would like to be able to reinstall Ubuntu 20.04.2 LTS, but I can't download it because I don't have an Internet connection.
