How is the security patch situation with that router, though? One reason a router upgrade is necessary so soon is just that the manufacturer abandoned it that soon. And then you're part of a botnet before you know it.
The latest Airport Extreme was released June 2013 and the most recent firmware update for it was Dec 20 2016. That's a longer lifespan than most consumer routers, and I expect the Airport will continue getting firmware updates for quite a while.
