I’ve seen many forums and posts regarding this but I can’t for the life of me get wifi to work and I’m about to break my monitor. I’m running a Gigabyte B550 Aorus AX V3 with the built in Intel B851 chipset which requires 8851 as a driver. I can’t find a linux work around. If someone can help me out I’d greatly appreciate it. I’ve tried installing 8852 drivers and I tried the windows driver AUR package, but I can’t get either of those to work.
Are you dual booting with Windows? What is the WiFi chip
inxi -Na
Edit: Okay i looked it up if this is correct.
Realtek® Wi-Fi 6 RTL8851BE
Windows is on a separate drive, yes. Box says 802.11ax wireless, system says it’s an intel based B851 chipset. And yes, that is the driver on Windows I installed.
Have you disabled the fast start up feature on Windows in windows power management. I would think this chip would run on the kernel module built in. Try setting Windows fast startup feature disabled and the reboot into EOS.
Edit: It should run on the r8169 kernel module is what i meant.
Still on windows for now. Fast start up is already off on my system.
Make sure you have removed the AUR package for the 8852 version then boot up after disabling the Windows fast start up feature. If this this doesn’t work try shutting down the computer and unplug the power supply. Press and hold the power button down for 30 secs or more and then try rebooting.
Edit: If it gets powered off in Windows on these boards that have WiFi bulit in it won’t start when booting into EOS. Hence why you need to disable the fast startup feature in Windows power management.
Edit: This chip is WiFi 6 not the AX WiFi 7 which is newer and has it’s own driver issues.
Fast startup was already off, I never used it. I tried turning it off and holding the power button, cable removed. As for how to remove the package I haven’t figured out how to do that yet lol I installed linux for the first time yesterday.
Hopefully you unplugged the power cord to the computer and then held down the power button for 30+ secs. Which package exactly did you install from the AUR?
I did. Let me find it real quick.
Edit: rtw89-dkms-git
rtl8852bu-dkms-git
I now realize the fact i added 2 might’ve been a problem lol
You installed both? Try removing both one at a time.
yay -R rtw89-dkms-git
yay -R rtl8852bu-dkms-git
Then reboot again.
Second one destination wasn’t found, it seemed like it was trying to overwrite when I added the different one so I didn’t think anything of it from that.
Edit: I still only see ethernet options, post seizure brain might not have been a good idea to try to figure this out lol
So inxi -Na doesn’t show the WiFi or it shows the output but has no module loaded (driver)
Edit: I assume you no WiFi showing up in the network icon if you click on it. Not sure what desktop you installed.

Am I just reading things wrong? xD Due to no internet when installing, it’s default EOS using an ISO downloaded yesterday. Prism by KDE is what shows when launching
This is from booting on the live ISO? It’s showing no module loaded. But it also shows the rtw89_8851be as being th module it needs.
On the installed system you can check rfkill
Also you can try loading the module sudo modprobe rtw89_8851be
You could also try installing the realtek specific firmware.
yay -S realtek-firmware
Again may need to reboot.
[kobaloi]$ rfkill

0 bluetooth hci0 unblocked unblocked
[kobaloi~]$ sudo modprobe rtw89_8851be
[sudo] password for kobaloi:

What is prism by Kde? 
That’s what shows in bottom right when launching.
Hmm …not noticed that.
While running that last command line it says realtek and linux are in conflict, remove linux-firmware?
