22.04.1 LTS Network Unclaimed for wireless adapter and ethernet port

au flag

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?

Don't know how. Sorry. Very new to Linux. I can try now.

Think I found it. Tried older kernel. No change.

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.

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.

Worked like a charm! Bonus points if you can help me output to my external tv monitor. HDMI not outputting signal

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
