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

1st Official Post

    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:

    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.
