My bad, I should have mentioned that I tried this one as well,
https://github.com/lwfinger/rtw88/commit/75e2c81 3weeks old, no difference

And it does not look like there was any change related to my problem since
then, is it still worth trying the very latest version? Btw reboot is not
really required, it is Linux, not Windows, rmmod+modprobe should do 😉 Thanks,
I added a bunch of stuff on April 24-25, so a 3-week old pull would have
missed some important stuff.
The problem with rmmod+modprobe is that the rtw88_core module is not removed,
certainly not with a 'sudo modprobe -rv rtw88_8822ce, and it is really easy to
get a mixed bunch. I get tired of explaining that to a bunch of newbies, thus
I recommend a reboot. Of course, I do not reboot.
Turns out I had to reboot because of the module signature :-/
Anyway it does not appear to work any better. Below are bad ping and good ping,
the difference is moving laptop 2cm to the left. I believe the right driver is
loaded as the modules are "rtw_" and not "rtw88_". It is quite bizarre how
moving the laptop for a little bit helps and moving it back does not necessarily
put it in the bad state, may be there is a microcrack in some PCB or something :-/

You do have the right modules. It would take a really strange environment where
moving the computer 2 cm would have a drastic effect.
I think I have gone as far as I can.
