I need some advice/help

[viktorbalazs]

Hello,

I have a DELL ProLiant N40L micro-server (a really old one) with a TP Link Wi-Fi USB adapter (Realtek RTL8811AU). I installed your module and the Wi-Fi stops working randomly. I changed the log level of the module and I got these lines after the last stop:

Could you help me please to avoid the random stops?

After this error, I tried to re-bind the device programmatically without success. So I have to remove and re-insert it manually.

Some details (I can provide more if needed):

• Ubuntu 24.04.1 LTS with kernel 6.8.0-51
• Driver version 8821au-20210708
• Device: TP-Link AC600 wireless Realtek RTL8811AU [Archer T2U Nano]
• Config:
  options 8821au rtw_drv_log_level=6 rtw_led_ctrl=1 rtw_power_mgnt=0

Hi @viktorbalazs

I'm looking to put this and my other Realtek WiFi 5 drivers into freeze mode after I update them to work with kernel 6.13. As of kernel 6.12, I think you will find the in-kernel driver works well. A lot of work has gone into rtw88 over the last year.

If you are using a kernel prior to 6.12, let me point you to the repo where the work has been done and you can install from there:

https://github.com/lwfinger/rtw88

I hope you understand. I would prefer my work go into things that are better for the future.

Hi @morrownr,

Thank you for your quick reply. Today, I checked the rtw88 repo as you suggested, but it's more unstable for me, so I'll still using the 8821au driver until the kernel updates to 6.12+ automatically (hopefully not in the too far future).

Thanks for your hard work on the drivers.

(Btw I have just realised this ticket is under a wrong repo, sorry for that. You can delete/move/close this if you want)

Hi @viktorbalazs

I realize you may not want to test but if you went to the rtw88 repo that I posted and there was a problem, it would be good if you reported the problem in the rtw88 repo and helped us fix it.
