The wifi adapter in my laptop is Realtek RTL8852AE. I am currently dual-booting Windows 11 and Ubuntu 20.04.3 LTS. I've gone through multiple options for what it could be, installed rtw89's repository for the realtek driver. Another suggestion was that windows might be shutting off the adapter to conserve power, but an option for unticking that for the adapter wasn't available when I tried in Windows 11.

Edit: The powermanagement tab does not appear when I go to properties for my network adapter in windows. I've tried enabling it with the CsEnabled registry key in Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power and then rebooting, alas it does not appear.

sudo lshw -C network output :

  • github.com/lwfinger/rtw89 did you mean you used this driver? Post the outputs of lshw -C network and nmcli device Commented Jan 4, 2022 at 16:25
  • Yes I used lwfinger's driver Commented Jan 4, 2022 at 16:30
  • Please add this in the question's description, because it is hard to read as a comment. Also, run the commands with sudo Commented Jan 4, 2022 at 16:33
  • I have also checked if any radiofunctions are blocked using sudo rfkill list all, but none of them are. Commented Jan 4, 2022 at 17:25
  • Does this answer your question? is it possible `cat` files role in ansible? Commented Jan 4, 2022 at 18:26

It turns out I managed to fix my problem with

sudo modprobe -v rtw89pci

which seemed to randomly start working again... not sure what to tell you.

I also made a script for that command and saved it in case I happen to boot up and have the same problem again.

Step 1 - Go to Bios Settings and disable Secure boot.

sudo apt update sudo apt install -y git build-essential git clone https://github.com/lwfinger/rtw89.git cd rtw89 make sudo make install sudo mkdir /usr/lib/firmware/rtw89

If mkdir does not work use -p with it.

sudo mkdir -p /usr/lib/firmware/rtw89 sudo cp rtw8852a_fw.bin /usr/lib/firmware/rtw89/ sudo modprobe rtw89pci

If modeprobe does not work, secure boot may be enabled. Disable it from BIOS settings and retry it.

sudo modprobe rtw89pci

  • You start with "Step 1", but then there aren't any other steps... Commented Mar 7, 2022 at 5:54
  • There is no need to disable secureboot entirely for all installed OS just for loading a kernel module. There are multiple other options including signing the module with your MOK or disabling kernel lockdown. Commented Mar 8, 2022 at 2:50
