My Unifi Security Gateway router can't connect to internet with ATT arris router

My Unifi Security Gateway router can't connect to internet when I connect with AT&T ARRIS BGW210 ethernet.

I connect the internet cable from ATT ARRIS router ethernet port is good, but when I pull that line to my Unifi security gateway in WAN port and connect a internet cord from the gateway 'LAN' port to my computer, the internet icon show 'no internet access'. Could you help to find out the problem? Thanks.

Hi @nickeves!

Thank you for reaching out to us here, we're happy to help you with your router configuration.

To get started, The unifi security gateway router need a WAN IP to distribute LAN IP's to devices so they can connect to your internet.

Did this solution work for your BGW210?

The website referred by the AT&T tech is for the Motorola NVG 510 and 589 and 2Wire/Pace Gateway.
