So based on the testing I have done, once you connect the MC-GW to a Wi-Fi router using WPS, that is the only router you can use. Unless you connect to ethernet and manually enter the new router information via MC-Studio.
The WPS process will not allow you to connect to any new Wi-Fi routers.
So my question now is there anyway to clear out the SSID & password information on the MC-GW so that you can start with a fresh MC-GW that you can connect using WPS?
