hello KSpyros
192.168.1.1 is the default IP of the Connect Box 3 set in Router Mode.
Once you enable Bridge Mode the IP of the Connect Box 3 changes to 192.168.100.1
A Factory Reset will enable Router Mode and you have to use the password shown on the bottom of the Connect Box 3. In this case connect a computer directly to the Connect Box 3. Do not use the wifi-password, there’s a second one for the login.
