I have ARRIS Surfboard model SVG2482AC running tv, internet & phone. Ring 2 would connect to Wifi but wouldn't get to internet. I went into arris firewall settings for 2.4 (ipv4) connection & changed from max security to medium security, saved & went through ring 2 setup told ring to use the 2.4 connection obviously & it's working fine now; suspect port on firewall was getting blocked. I may go into admin later to limit # ipv4 connections as most our devices use 5G. Hope this helps.
