[Solved] wifi issue rtw8852be

[olih10200]

Hi Folks,

My problem is, that the new wifi6 never works, while image greater than subver. 13 ...

This is the working state:

Code: Select all

root@xxx:~# lsmod | grep rtw
rtw_8852be             16384  0
rtw_8852b             372736  1 rtw_8852be
rtw89pci               65536  1 rtw_8852be
rtw89core             540672  2 rtw89pci,rtw_8852b
mac80211             1175552  2 rtw89pci,rtw89core
cfg80211             1134592  3 rtw89core,mac80211,rtw_8852b
root@xxx:~# uname -a
Linux xxx 6.1.0-13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.55-1 (2023-09-29) x86_64 GNU/Linux

All later builds of kernel cannot use the card ( it is an HP laptop )

Any idea, what can i do? Where can i post my issue?

thx

Of course, non-free and non-free-firmware are in sources ( bookworm )

Hello,

The rtw8852be seems an unofficial kernel module (for Debian). Where did you get it ?

May you report hardware details of your network adapter ? You can use the following commands:

Code: Select all

lspci -vnn -d::02xx
lsusb

It is "fully" official ...

but, as you wish:

Hello,

It is "fully" official ...

I don't think so

Code: Select all

[02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8852BE PCIe 802.11ax Wireless Network Controller [1T1R] [10ec:b85b]
	Subsystem: Hewlett-Packard Company RTL8852BE PCIe 802.11ax Wireless Network Controller [1T1R] [103c:88e6]
	Flags: bus master, fast devsel, latency 0, IRQ 83, IOMMU group 10
	I/O ports at f000 [size=256]
	Memory at fce00000 (64-bit, non-prefetchable) [size=1M]
[..]
	Kernel driver in use: rtw89_8852be
	Kernel modules: rtw_8852be

As you can see, the kernel driver in use is rtw89_8852be and rtw_8852be:

Code: Select all

	Kernel driver in use: rtw89_8852be
	Kernel modules: rtw_8852be

The kernel modules listed above are different from those listed below and distributed with the Debian GNU/Linux kernel (linux-image-6.1.0-13-amd64):

Code: Select all

# dpkg -S rtw89_8852
linux-image-6.1.0-13-amd64: /lib/modules/6.1.0-13-amd64/kernel/drivers/net/wireless/realtek/rtw89/rtw89_8852ae.ko
linux-image-6.1.0-13-amd64: /lib/modules/6.1.0-13-amd64/kernel/drivers/net/wireless/realtek/rtw89/rtw89_8852a.ko
# apt-cache show linux-image-6.1.0-13-amd64
Package: linux-image-6.1.0-13-amd64
[..]

The rtw_8852be.ko and rtw_8852be.ko are not in Debian GNU/Linux kernel:

Code: Select all

$ cat /etc/debian_version 
12.5
$ dpkg -S rtw89_8852be
dpkg-query: no path found matching pattern *rtw89_8852be*
$ dpkg -S rtw_8852be
dpkg-query: no path found matching pattern *rtw_8852be*

Therefore, I assume you are using an out of the tree kernel module that perhaps does not compile on kernel versions > 6.1.0-13

You can try compiling it to check for errors.

Otherwise, your WiFi adapter "RTL8852BE PCIe 802.11ax Wireless Network Controller" should be supported natively from Linux kernel version >= 6.2 [1][2]. Therefore, you may install the kernel version 6.5 from debian stable-backports repositories [3].

Hope this helps. Please let me know.

Hi @Aki,

I'm sorry, i've made a mistake, you're right ... indeed, when i couldn't make to work my wifi, i've found a project at github ( xorry, have forgotten ) ...

lwfinger/rtw89 project

... and sorry, not fully RTFM

After recompile with the newest kernel, all OK now:

Code: Select all

Linux XXX 6.1.0-18-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.76-1 (2024-02-01) x86_64 GNU/Linux

Code: Select all

# lsmod | grep 885
rtw_8852be             16384  0
rtw_8852b             372736  1 rtw_8852be
rtw89pci               65536  1 rtw_8852be
rtw89core             540672  2 rtw89pci,rtw_8852b
cfg80211             1142784  3 rtw89core,mac80211,rtw_8852b

Next time i'll ask kernel developers, what about with it at the official kernel

Once more xorry for wasting your time, and very thanks for you, pointing the error or me ...

Bye
