AirPort Extreme 802.11n (5th gen) and Time Capsule (4th gen)

AirPort Extreme is a discontinued line of residential gateways made by Apple Inc. that combine the functions of a router, network switch, wireless access point and NAS as well as varied other functions. The latest model, the 6th generation, supports 802.11ac networking in addition to older standards. Versions of the same system with a built-in network-accessible hard drive are known as the AirPort Time Capsule.

Apple discontinued its wireless routers in 2018, but as of 2023 continues limited hardware and software support.

The AirPort Time Capsule (originally named Time Capsule) is a wireless router which was sold by Apple Inc., featuring network-attached storage (NAS) and a residential gateway router, and is one of Apple's AirPort products. It is essentially a version of the AirPort Extreme with an internal hard drive. Apple describes it as a "Backup Appliance", designed to work in tandem with the Time Machine backup software utility introduced in Mac OS X Leopard 10.5.

Introduced on January 15, 2008 and released on February 29, 2008, the device has been upgraded several times, matching upgrades in the Extreme series routers. The earliest versions supported 802.11n wireless and came with a 500 GB hard drive in the base model, while the latest model, introduced in 2013, features 802.11ac and a 3 TB hard drive. All models include four Gigabit Ethernet ports (3 LAN ports, 1 WAN port) and a single USB port. The USB port can be used for external peripheral devices to be shared over the network, such as external hard drives or printers. The NAS functionality utilizes a built-in "server grade" hard drive.
