Wifi adapter not found

I am dual booting Windows 11 and Fedora 38. My Wifi was working until I restarted, booted into Windows and updated windows. Secure boot is disabled. My dell latitude has a fast boot setting in the Sytem BIOS settings; I set that to “Thorough.” I disabled fast boot in windows using Powershell’s:

powercfg /h off

command. Here are some useful snippets:

Things I’ve tried:

  1. Rebooting the system
  2. Disabled secure boot
  3. running ❯ sudo dnf install -y NetworkManager-wifi iwlwifi-dvm-firmware-20230919-1.fc39.noarch
  4. running ❯ sudo dnf update -y && sudo dnf upgrade -y

I’ve read lots of articles and Reddit posts but nothing has worked so far.

Note that you are quite some ways behind with that firmware

$ dnf list installed iwlwifi*firmware
Installed Packages
iwlwifi-dvm-firmware.noarch                                         20231111-1.fc39                                         @updates
iwlwifi-mvm-firmware.noarch                                         20231111-1.fc39                                         @updates

It might assist if you were to do a full sudo dnf upgrade --refresh then reboot to see if upgraded software and firmware may fix the problem. It is quite possible that your problem has already been fixed and a simple update may fix it.

If the update does not fix it then revisit the problem here and show current installed versions when you come back.

(Yes I know you already said you upgraded, but the firmware package you posted says otherwise.)

After running what you suggested, here’s what I got:

❯ sudo dnf upgrade --refresh

I ran the command and rebooted. I then the following(output attached):

❯ sudo dnf update -y && sudo dnf upgrade -y

WiFi works in Windows 11. Let me run a live usb and see if it works on that as well

Update: Wifi works in a live Ubuntu image

With that command you are repeating the same exact thing twice.
Within dnf ‘update’ is an alias for ‘upgrade’ so either one may be used and they do the same thing.

Thanks for the info. At this point, should I try to remove all wifi drivers and reinstall them? Or is that a dead-end?

I plugged in another external wifi adapter and it works. Its info is:

Device-3: Qualcomm Atheros AR9271 802.11n driver: ath9k_htc type: USB
  IF: wlp0s20f0u4 state: up mac: --snip--

With an immense amount of help from ChatGPT, I managed to get it working. We figured out basically that sudo iw dev wlo1 scan was working but sudo nmcli device wifi list was not working. What I then discovered was that in /etc/NetworkManager/NetworkManager.conf there was a line unmanaged-devices=interface-name:wlo1 that was causing all the issues. Because of that one line, NetworkManager was not managing wlo1. I commented that out, restarted NetworkManager and everything started working.

Thanks Jeff

Glad you were able to find the answer. Sometimes the seemingly innocuous thing in the configs has strange consequences. :+1:
