A recent update seems to have caused problems with my machine's wifi card. I have it running on a wired connection at the moment. Prior to the update, I believe Settings->Network had a WiFi section. Now it does not. Per 22.04.1 Network Unclaimed I have installed linux-modules-extra-6.2.0-39-generic
. Along the way I installed linux-headers-generic
and ubuntu-drivers autoinstall
(though that one may have been to fix Nvidia -- it's been an eventful update). I have also poked around in grub and clicked on "enable networking".
At this point I'm turned around, and if a kindly expert was willing to help me figure out the problem I'd be most grateful.
Some system info:
$ uname -a
Linux xxxxx 6.2.0-39-generic #40~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Nov 16 10:53:04 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
Below we can see that the WiFi card is present.
$ sudo lshw -C network

What additional information would be helpful?
sudo apt install bcmwl-kernel-source
and reboot. – chili555 Dec 15 '23 at 02:15
