      @dashrender I think I tried as low as 1400 but not that low.

        I know you can point an AP to the IP of the controller. Is that an option here?

        What's the adoption process we are talking about.

          @dashrender Even tried that and it adopts. I tried to then migrate from that local controller to the online one and no luck. I had the ISP make a change (increase MTU) and going to try when the new one arrives tomorrow. Hopefully that will fix the issue.

          Can you change the MTU of the USG to 1350 or so? I know you mentioned you did that in the past on a server, didn't see you mention you did it here.

          The provider upped the MTU to over 2000 for us.

            The new router arrived and adopted without any issues. It would have been nice to try the old router since the MTU changed so we know which of the two was the fix, but I am happy to report all is working well with the new router in place.

            Sending in the old one for RMA credit.

              @ccwtech I had a similar issue on a Unifi Switch once ... It took me forever to track the issue down and in the end, it was such a simple thing that pissed me off. Apparently someone had installed some IP cameras on the network and assigned a static IP address that was conflicting with the network switch. A new device would cure you because with a new mac, a new IP. Just something to check out.

                @krzykat This wouldn't have been that. Was just worth getting an RMA and starting fresh.
