My Asus RT-AC66 has been running like a champ for about two years. Keep the firmware current on it...well, within at least one release of the latest. Don't check it too religiously....maybe every other month or so or if I have long Windows Update cycles on the laptops. Might want to make sure the one you get supports open source firmwares (tomato, Merlin, DD-WRT, etc.). Saw a thread recently where moving to open source resolved that user's local LAN multiple console issue. Could be nice to have that as an option for testing things out down the line.
