Realtek Wi Fi adapter not recognized

User Support Hardware Issues

Recently I installed Qubes OS version 4.2. However, I have issues with my Wi Fi connectivity as my adapter is not being recognized. For my sys-net service I am using debian-12 with kernel 6.6.2-1.fc37.

root@sys-net:~# lspci | grep Network
00:06.0 Network controller: Realtek Semiconductor Co., Ltd. Device b852

In other topics I read that this adapter is associated with kernel module rtw89_8852be, which in my case is linked to my adapter, however, it still appears as UNCLAIMED.

I can see an error in the kernel logs when the rtw89_8852be module is being loaded.

I would be really thankful to hear any ideas how we can fix this issue.

What’s your adapter VID:PID?
You can check it with:

lspci -vnn -s 00:06.0

Maybe you can try to use newer firmware in sys-net.
