I am selling a fourth-generation Apple AirPort Extreme base station. Model A1354. It is updated to the latest firmware version. Supports a guest network feature, and also supports 802.11 a/b/g/n.

This AirPort has served me well for years and is still in perfect working order. I love this router. It has great signal and I don't remember ever having to reboot it, unlike other routers I've had in the past. And the AirPort Utility makes it a breeze to setup with your Mac, PC, iPad or iPhone.
