Netduma R1 hook up to Xfinity Modem in Request 1 on 1 Posted 8 hours ago It's not an artificial limitation, our router can't just hijack your existing router to force it to prioritize packets. The Netduma can't control traffic that isn't routed through the Netduma. This is a physical limitation, and could not be solved by any router without replacing your existing ISP router. The solution would be to place the Netduma at the top of your network, and connect it to your PS4 and your Xfinity modem via ethernet, then you can continue to use the Xfinity wifi. This would allow you to specify a chunk of bandwidth just for the PS4. The difficulty is that it would require another modem above the Netduma, as the Netduma is just a router and not a modem.
