Can’t connect tv to the new gateway modem
Are you saying your TV doesn't find your SSID? That's the way I connect all my wireless devices
If you are attempting to connect it via WiFi, are you associating it with your home network's current WiFi broadcast name (SSID) and your WiFi network's current password / network security key ?
Well you need to be certain that it is connecting to your home network's broadcast name (SSID) and that you are using the correct password / network key, or it won't work..
