I have the mt1300 and latest update. I am going to repeater mode selecting the public(maybe that wasn’t clear before, this is not to a modem/WiFi router like at home, this is the public xfinity WiFi hotspots found out and about) xfinitywifi ssid(5ghz) and trying to connect and it times out everytime. This is all with no special dns settings and not cloning the MAC address.
