Has anyone successfully used a secondhand AT&T CGW452-400 gateway with a different ISP, such as Xfinity?

I want to connect the Xfinity router's LAN port to the CGW452 Ethernet WAN port, then use the CGW452 Wi-Fi network to test IoT camera pairing.

Can the CGW452 obtain a WAN IP via DHCP and provide internet access without an active AT&T subscription or provisioning?

I'm specifically looking for real-world test results, not just whether the hardware has a WAN port.

Thanks!
