[RPi3] Kodi doesn't reconnect automatically to WiFi after a blackout

    The solution with 2 WiFi networks kind of satisfies my needs at the moment as it will just switch after every boot. Of course only works because my router and my RasPi have good 2.4 and 5 GHz reception.

    Hi,

    I faced same problem that RPI 3 with LE 12 doesn't connect to WIFI after reboot and when entering connection details manually after reboot I got "Invalid Password" cycle.

    With LE 9 it was working without any problems.. System was few years unused since I managed to corrupt system with some update, so I made clean install LE12 to new SD card.

    I did try to fix this with scripting and creating service to find out if system has IP if not force it, since Connaman doesn't like too much forking it didn't work.


    Next I tried via Connman doing autostart script, simply Connman enable wifi, that didn't work as expected either, behavior was strange. I have two wifi network 2,5 and 5 it was connecting to 2,5 and IP was visible, but no internet connection.. Trying to connect manually lead yet again to "invalid password" cycle.. After 30 seconds later system reboot itself, not fully and both networks were IDLE without IP. After that entering connection details password was accepted.


    Running wifi details RSSI level was -69 or -70 which should be ok for packet delivery. With another RPI I tested in same spot (LE 9 installed ) no issues on connecting. So my assumption is that it is not HW issue..


    Problem is a bit annoying since when scheduling TV recording WIFI might be lost some point and system clock somehow resets and recording fails..


    I could try this out with RPI 4 as well even though I believe that situation will be exactly the same.
