JC's Asus router is no longer supported by the company. What router should he buy? Leo says he doesn't really have to buy a new router. He can install DDWRT's firmware on it and then keep that router up to date. The chatroom recommends going to asus-wrtmerlin.net for a custom firmware for the Asus router.
But if he wants a new one, Leo recommends getting a mesh router, especially for a house as large as JC's (2500 sq ft). A base station and a beacon would be good. Leo's favorite is Eero.
