Libreelec on Rpi3 freezes when Edimax EW-7811UTC is connected on 5ghz wifi

Hi!

I read that the Edimax EW-7811UTC should work ootb with LE 8.2.1on a Rpi3

Indeed it connects but as the title says it freezes- during playback or during browsing the Menu.

I uploaded a complete log here:

The router used is a Asus DSL 68U.

The 5ghz wifi is configured on 80mhz, channel 48 if that matters.

Are there any good sticks with a different chipset out I could try?

The Edimax EW-7811UTC uses a Realtek chipset.

Thanks!

I'm wondering what happens in between those 2 lines:

09:13:17.404 T:1945120768 DEBUG: ------ Window Deinit (DialogNotification.xml) ------

as there seems to be a couple of hours between them?!

A similar jump seems to be in the kodi.old.log:

The same behavior appears when using osmc.

leading to the conclusion that is not a libreelec problem.

Both LE and OSMC are stuck using the same sh1t out-of-tree vendor provided drivers. Realtek should really be taken into a dark alley and beaten senseless until their policy of hiring school kids to write crap drivers that are not upstreamed to the mainline kernel is changed.

True!

Following:

rtl8812au wifi dongle on RPi 3

"rpi3:~ # cat /etc/modprobe.d/8812au.conf
options 8812au rtw_power_mgnt=0 rtw_enusbss=0 rtw_ips_mode=1 rtw_vht_enable=0 rtw_ht_enable=1"

did the trick.

Limits the wifi to N instead of AC but seems to be more stable as far as I can tell from the testing I have done so far.
