Strange WLAN Bug: WPA2 works, WPA3 doesn't

Knecker · 21 April 2021 18:53

Fellow Manjarees,

I have stumbled across a very strange bug, where a connection will only work, when connecting with WPA2 instead of WPA3 enabled.

The scenario:
In my local WLAN, I have 6 machines: 2 PCs, 2 Notebooks and 2 Mobile Phones.

PCs and Notebooks are all running the latest manjaro with updates.
All are connected via WLAN to a router (FritzBox 7590) with WPA3 in a local network enviroment.
Everything works.

The bug
Now, due to stupid user (me) mishandling, I wrecked the Linux installation of one of the Notebooks (related to swiching between Pipewire and Pulseaudio). To get rid of the problems, I opted for a fresh install of Manjaro on the Notebook. Suprisingly, after installing Manjaro and providing a network driver for the RTL8821CE Wlan chipset, I could not connect to my local network.
After wrecking my brain of all thinkable and unthinkable things (and trying them out) I stumbled across the security setting. And here things are getting really crazy: The network manager connects without any problems, when selecting WPA2 Personal for password transmission, but NOT when selecting WPA3 - as it has been, before the reinstall… and is still selected, on all other machines in the network.

It is definetly not…

…the notebook: Apart from doing a fresh install of manjaro, no hardware or BIOS setting has been changed
…a general problem with WPA3: I was able to connect the notebook to another WLAN network (mobile hotspot) using WPA3 with no problems (!). But it also can not be…
…the router providing the WLAN: Automatic updates were disabled and no setting has been changed manually + all other machines are still connecting without problems using WPA3.

So, quite baffling. Again.
Any ideas? Any clues? I am out of answers as to this point.
Help would be much appreciated

Have you been able to solve the problem?

I kind of … might have?
So, the problem might be, that the Linux Kernel 5.9 version comes with a broken rtw88 module developed by Realtek that has poor compatibility with most revision of the 8821ce chip. Unfortunately, this issue has NOT been resolved as to this date.

The solution is to use this custom driver by Tomas Pinho (and multiple contributors):

I personally reverted back to an older LTS kernel and used the custom driver from the AUR.

I hope, that helps.
