wont work

Could you please provide us with your product’s model number?

Also, could you elaborate on the issue you're experiencing so that we can assist you further?

It’s a G 18, it won’t let me open most websites, it won’t allow my TV to connect. Is there some sort of built-in firewall on this thing?

Are you able to access certain websites when connected to the G18 network, or do you experience the same issue even when using mobile data?

For better results when connecting your TV to Wi-Fi:

• Try connecting it to the 2.4GHz network instead of the 5GHz one, as some TVs work better with 2.4GHz.
• Also, consider changing the security type for the 2.4GHz network which can sometimes cause compatibility issues with certain devices.

Please refer to the instructions below for steps on how to change the Wi-Fi security settings
