so a few days into this i found that it now is possible to connect wifi over host->system->change, but while doing so it connects and keeps disconnecting a short time afterwards.
also tried to edit the connection over nmcli again nmcli con edit 'CONNECTION' and in the editor i then closed with save persistent like mentioned here.
tried dhcp and static ip with the HassIO network manager under host->system->change but doesnt get any other results.
perhaps this could be something with routing table im not able to see because of my lack of knowledge – pls if anyone has a clue how to get this fixed i would really appreciate!
greetings
