No internet connection

I'm using an Xfinity Wireless gateway. The white light is on but no internet connection. This problem has been going on for a year now. When I factory reset the gateway back to it's default it works for a few minutes then goed offline again. All the cords are plugged in, I've tried everything, all the devices have assigned IP's, the DNS is configured properly, and I can't tell whats wrong. The TV works perfectly fine. Also when it is online my gaming devices can connect to the wifi but have never had any internet connection through it.

Did you contact Xfinity support since it's their device? Not much you can do here if they can't fix it, you can ask them to get you a modem and you can purchase your own router possibly.
