So need a router with built in modem (rj45 only not telephone line port) Currently I am using an entry level netgear with excitel and it's giving me pain for VOIP calls (whatsapp/skype/SIP) and gaming with PS4(with LAN). * Coverage is not a problem as it is needed for one small living room. * Excitel is moving to fiber soon and hathway already is , so a router which can support fiber and Ethernet WAN both will be atleast future proof * latency should be least. I will be playing only fifa 18 on PS4 multiplayer over PSN so need rock stable connection. * 2.4GHz and 5GHz should both be supported. * Should support excitel and hathway connections. most imp is lag free gaming and voip.
