Hi im checking how to set up my wifi. I already use homeassistent for a few weeks now.
Can’t find anything i can read. Pls. maybe anyone with a probably simple answer 
If you could give us more details on what it is exactly you want to achieve it would be very helpful. I don’t think anyone could give you a “simple” answer if the question stays this vague.
Do you want your Raspberry (or any other device that runs HA) to connect via wifi? If yes than I would highly advise you against it. If it is something else you want please give us details 
okay i have reinstalled homeassistent with wifi. But thnx for replying.
