Incompatibility with Thinkpad E16 RTL8852BE PCIe 802.11ax Wireless Network Controller

[PickleGaming32]

Facing issue on multiple linux distros (Fedora, openSUSE, debian, archlinux) where Wireless Network Controller shuts down completely after unsepcified amount of time. It shows up in lspci, but after it shuts down, neither lspci or any other form of hardware monitoring manages to show it. Even after having installed these drivers correctly, with the help of other archlinux users, I am facing the same issue, such that I have been advised to submit a ticket.

I believe may be I am suffering from the same problem, with my Lenovo Thinkpad E16.

In my case I am using Debian GNU/Linux 12, as the official Debian kernels do not support my wireless NIC, I was using lwfinger/rtw89 . It was working fine for me.

The drivers were working fine on Linux kernel images:

• linux-image-6.1.0-13-amd64
• linux-image-6.1.0-16-amd64
• linux-image-6.1.0-17-amd64
• linux-image-6.1.0-18-amd64

but from the below releases on-wards the driver builds are successful, but the the new driver is not working.

• linux-image-6.1.0-22-amd64
• linux-image-6.1.0-23-amd64

So I have went back to Linux kernel image linux-image-6.1.0-18-amd64 from Debian repo. That is how I continue to work from my E16.

Thanks

Thanks for your input.

While I am thankful that there are some linux (especially debian) images that work with this NIC, do you have any idea if some of the older archlinux images may solve this issue? Debian's awesome, but I'd love to stick to arch if at all possible.

Thanks.

I was reading this issue reported:

#364

In this issue @prodrone-liu got the WiFi driver working with commit #ebe87ac in his Ubuntu 20.04

I tried checking out to this commit #ebe87ac in my Thinkpad E16 with Debian 12 and the driver builds are successful, also the new WiFi driver is not working on my Debian.

May be this commit #ebe87ac will help you. Give it a try.

Thanks.
