I did as you said and it "kind of worked".
So i am now able to get connected to the board. However when ever I make a change in the config.g file (eather by putting SD in PC or by web edit) the system will not be able to get connected again. (f.ex. I changed the IP adress and after that I was not able to connect to the printer (on eather IP adress.
So far I havent tested that much but I will try to soon to maybe get an idea.
