@RanchHand Hi Please try to hard reset the EAP and then readopt it on the OC200 to see if you can fix the issue. (press and hold the reset button on the device itself)

@ggeoffreyyy 1. If you want to use the mesh function, all APs need to support mesh. 2. Eap660 does not support mesh yet. I heard from tplink that future firmware will support this function.

@K.J.M Hi, I believe the Group ID caused the issue, try to input any number from 1-8 in these two ports.（The two ports should be filled with the same number）

@dbro The default IP of the ER605 is 192.168.0.1

@Cellcom I think what they are trying to say is that if you are not using another tplink product and only have an oc300, then there is no way for the oc300 to discover and manage third party devices,...

@Benje Hi, According to my understanding, there is no way to view the specific network behavior of the client on the SDN controller.
