I lost all ability to connect to the internet on Linux Ubuntu 22.04.1 LTS. Sudo lshw -class network shows both the wireless adapter and network port as 'Unclaimed'. Read in other posts that means the hardware doesn't have the drivers. I don't know where to find them or how to install them without connectivity. Please help.

If you boot into an earlier kernel version at the GRUB menu, do they work?– chili555Commented Dec 16, 2022 at 23:50

Don't know how. Sorry. Very new to Linux. I can try now.– Clyde_MurphyCommented Dec 16, 2022 at 23:58

Think I found it. Tried older kernel. No change.– Clyde_MurphyCommented Dec 17, 2022 at 0:24

Switched to another kernel. I think there were technically three versions in the grub menu. Wifi is back! Good to know. Just wish I could still use on external monitor. Newer kernel let's me mirror onto a TV but wireless disappears. Old kernel does the opposite.– Clyde_MurphyCommented Dec 17, 2022 at 0:48

Boot into the latest kernel where the wireless doesn’t work. Run the command:
uname -r
Make careful note of the exact kernel version; as an example, 5.15.0-99-generic.
Also run:
sudo dpkg -s linux-modules-extra-$(uname -r) | grep Status
I am quite confident that you’ll find that the package is not installed.
Boot back into the earlier kernel version where the wireless does work and run:
sudo apt update
sudo apt install linux-modules-extra-5.15.0-99-generic
Of course, substitute the kernel version you noted above.
After the installation is complete, reboot. You should be all set.
