[SOLVED] Motherboard Wifi Stopped

[Don]

I have a Gigabyte Z370 HD3P-CF mobo, which has been working just fine. The wifi was fully functioning after I upgraded to Jammy. Now it doesn't function at all. (I have a wired connection for this machine, so this isn't (yet) a disaster.) I know the router is functioning properly, because I can still see and connect to my wireless network with other devices.

I will probably supply below more information than needed, but it may save some back-and-forth time.

The relevant portion of inxi shows:

I don't see a wireless device there, but perhaps I don't understand what I'm looking at.

None of that seems to me to relate to wireless.

I have looked at the BIOS, but I did not see a particular setting for wireless. Besides, I haven't messed with the BIOS since I built the machine.

Any ideas? Thanks.

if the wifi card is not even being detected, you may have to see if has somehow become dislodged or something, or gone bad, even.
Even if the driver was missing entirely from the kernel, the device info would still show in lspci.

I can't find details of what wifi card it is supposed to have, so I am guessing this was an OEM motherboard?
Gigabyte don't seem to list a Z370 HD3P-CF, just a HD3P which doesn't have WiFi built in, and what I see on https://linux-hardware.org for the board shows any number of different cards.
Unless it is an addon PCI card, even an on-board Wifi chip is usually just an m.2 style card in a custom bracket.

Actually, the lack of Bluetooth in your lsusb output also makes me think that there may be something physically wrong with the hardware, since that is provided by the Wifi card.

Just to chime in needlessly . . . The wifi was working fine with jammy and then suddenly stopped? If that is correct, then I also agree with Claydoh, the card may have given out finally. They do go bad. Esp considering the bluetooth is also not being detected, which is probably on the wifi card. If this is a dual boot system with windows and a newer wfi card, you can try holding in the power button for 30+ seconds to clear the state saved on the wifi card by some windows drivers. Unplugging the power source (battery/powercable) for 30+ seconds can also help. If this is not a dual boot system with windows/linux then this is unlikely to help. In that case it is likely. as claydoh stated, to be a card that has died on you. EOL >> End of Life. It happens. One way to test to make sure is to boot from a live DVD/USB and try Kubuntu to see if you wifi has the same problem. Try another Linux distro as well. If wifi no longer works with them, then likely it is dead.

Go to a terminal and issue this command and post the output here.

Claydoh,
Bingo! The mobo chip must have been just a tad loose. I found it, pushed on it (I didn't force it; I used my smallest hammer), and I'm back in business. Many thanks.

Glad you got it going
At some point you may want to pull it out of the slot and clean the contacts with contact cleaner.

Glad it is sorted!
It is easy to blame the OS first, but after blaming Linux too many times for something that ended up being hardware or PEBKAC, I finally learned to look at all The Things.

On the flip side, I bought an old, unopened Logitech Bluetooth trackpad for 30 bucks from Ebay two weeks ago. The internal battery was bulging. I took it apart and replaced that, but the dang thing would connect, but not be seen as an input device. So I though it was a dud, a chance I took on something so cheap. This one turned out to be an actual OS problem
or rather a huge dash of PEBKAC casing an OS problem

[Don]

I never meant to blame the OS. In fact, I was pretty sure it had nothing to do with the OS. I just came here since it's the best place to find out about almost any problem on a Linux box.
