Network controller unclaimed only in Recovery

de flag

An update to the Nvidia drivers causes my Ubuntu 22.04.1 (Kernel 5.15.0-53) to not boot beyond a black screen with a blinking cursor, and most suggestions to resuscitate this involve purging and installing a different driver from the recovery (or using Ctrl Alt F1-7 on the black screen).

However, I am not able to connect to the internet at all.

lspci shows my WiFi adapter, but

nmcli dev status only shows the lo device (unmanaged), and lshw lists my network controller as being unclaimed.

None of these issues happen when I boot into a previous version of the kernel; the output of nmcli dev status shows both the WiFi controller as well as external Ethernet adapters. Is there a way to manually load the drivers for these? Restarting NetworkManager has not helped.

Thanks!

(P. S. I know that I can just use the previous version of the kernel to roll back the driver, but I would like to fix this issue for if/when an update breaks both kernels)

Please edit your question to show the result of the terminal command: `sudo dpkg -s linux-modules-extra-5.15.0-53-generic | grep Status` Welcome to Ask Ubuntu.

This kernel upgrade had the same impact on me (although I could boot from recovery mode even though I had access to only one of my displays). Here's the output from `sudo dpkg -s linux-modules-extra-5.15.0-53-generic | grep Status` on my machine (when booted using 5.15.0-52): `Status: install ok installed`

@chili555 I apologize for not responding sooner. That was, in fact, the root of the problem - the extra modules weren't installed for some reason. After re-installing the 5.15.0-53 kernel and the extra modules, everything works fine (display as well as internet connectivity). If you would like to reply with an answer, I would be happy to accept it. Thank you!

As you confirmed in your comment, linux-modules-extra was not installed. From an earlier working kernel version, please do:

sudo apt update
sudo apt install --reinstall linux-modules-extra-5.15.0-53-generic

Reboot. You should be all set.

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.
