Hello. I've been with Sonic for a few years and I've been using a TP Link TD-W8960N Modem Router. I think it's starting to have issues so I would like to purchase a new Modem/Router. Can someone please suggest one that will work with my Sonic service? I would really appreciate a precise brand/model number as opposed to something like "any router that is IPV6 TTX ORTV and MDP compliant - which I won't understand". Thank you!!
