rtl8822bu chips are already supported by kernel v6.3.x.

Hi. It seems that latest kernel 6.3.x supports rtl8822bu chips natively (there is no longer need to compile own driver in my case):

@rrafal1337 Hi, Just to make this clear :

Are you using Linux Fedora FC38 with kernel version 6.3.5 ?

Maybe you can change the title of this issue to more clear like rtl8822bu chips are already supported by kernel v6.3.x.

@rrafal1337 Hi, Just to make this clear :

Are you using Linux Fedora FC38 with kernel version 6.3.5 ?

Yes. I was used previously driver from this project but for now shipped with kernel 6.3 in latest Fedora 38 solves my problem.

Maybe you can change the title of this issue to more clear like rtl8822bu chips are already supported by kernel v6.3.x.

Already changed. Thanks for suggestion.

[schauveau]

The driver is not in all v6.3.x kernels. I am currently running 6.3.0 in Debian Testing and it is not there.

According to https://packages.debian.org, the module rtw88_8822bu.ko is in the linux-image-6.4.0 packages from Debian Experimental.

[shenlebantongying]

I can confirm that with Linux 6.4 (archlinux), RTL88x2bu works out of the box.

[sebma]

@schauveau And also in Debian Sid 😄 : https://packages.debian.org/search?suite=sid&arch=amd64&mode=path&searchon=contents&keywords=rtw88_8822bu.ko

It is also in Ubuntu 23.04+ with kernel v6.2.0-20-generic : https://packages.ubuntu.com/search?suite=lunar&arch=amd64&mode=exactfilename&searchon=contents&keywords=rtw88_8822bu.ko .
And in Ubuntu mantic with kernel v6.3.0-7-generic : https://packages.ubuntu.com/search?suite=mantic&arch=amd64&mode=exactfilename&searchon=contents&keywords=rtw88_8822bu.ko

[gittrekt]

Sorry for bumping old thread, but...

Linux fedora 6.8.11-300.fc40.x86_64
rtl8822bu works out of box, but crashes under heavy load. This is still a viable solution for now

[MaxG87]

I just want to point out that for some users the driver appears to work at first glance but causes subtle issues later on. One particular problem is a loss of connectivity after about an hour of usage. More subtle issues are reported here.

[3vi1]

My experience matches @gittrekt. I have two USB 88x2bu adapters and both of them will fail such that I need to unload/reload the drivers to get them going after just a few days. I've seen this since they were introduced all the way to the current 6.11 mainline kernel. I especially see the problems start showing when I'm doing system backups to my external USB drives.

@MaxG87 's drivers, on the other hand, are rock solid and never drop out - no matter the system load.

[schauveau]

I also noticed that my USB rtw88_8822bu from kernel 6.10.6-amd64 (debian) is quite unstable.
I occasionally have to unplug/re-plug it.
I never bothered to really investigate since this is a old machine that I intend to replace soon.
