@Lobo83 I managed to get it to work! Replying so it might help someone else. I think there is a bug somewhere in the RE200. I always connected to my 5ghz network or both the 2.4 and 5 ghz networks...

I recently reset my RE200 after some things stopped working and am trying to set it up properly again. It's connected to my main router (A netgear nighthawk R7000) and a NAS is connected to the RE200...
