Suddenly, no available wifi networks

[szymonlipinski]

I've checked kernels 5.15.x, 5.17.x, 5.19.0, 5.19.2, 5.19.11.

At this moment I have Linux ymon00 5.19.2-051902-generic #202208171037 SMP PREEMPT_DYNAMIC Wed Aug 17 14:41:19 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

The driver is installed manually from the master, with debug on.

rtl8821ce/5.5.2.1: added
rtl8821ce/v5.5.2_34066.20200325, 5.19.2-051902-generic, x86_64: installed

After sudo modprobe 8821ce the network applet is spinning all the time trying to find networks. Dmsg shows this:

[dubhater]

That's the entire log? It goes into ips mode and never even tries to leave it?

Try the module parameter rtw_ips_mode=0.

[szymonlipinski]

Yes, that's the entire log. After adding ./rtl8821ce.conf:options 8821ce rtw_ips_mode=0 unloading and loading the module ends with:

[dubhater]

Weird.

Why do you say "suddenly"? Did this driver work before?

[szymonlipinski]

Yes, it worked all the time I get this notebook... which is about six months. Yesterday my computer froze and after reboot the driver was not working. Btw, I moved to Ubuntu 22.10 a week ago. I checked the history of installation stuff and there is nothing which could cause any problems.

[szymonlipinski]

Installing iwctl and enabling it helped. All works for now.
