How to Set Up the WiFi Username & Password
EasyConnect
The Hitron CGN3u modem must be set up through EasyConnect before you can access the internet.
Connect to SSID: EasyConnect##### (last 5 digits of customers serial number). You can also use an ethernet connection.
If the EasyConnect page doesn't show, connect to 192.168.0.1.
Reboot the Hitron if you cannot open the EasyConnect screen.
Press [ LET'S GO ].
Continue with the prompts on screen. Create a wireless SSID and password.
Click Close once finished on the Review Stage
Connect to the new wireless network you created.
The connection should be online and the normal CGN3 interface should be accessible via 192.168.0.1 (The admin password will now be the same as the wireless key.)
