Genuine used Apple AirPort Extreme Base Station 802.11n (4th Generation) Wi-Fi router.  In very good condition and works perfectly (tested before posting auction).  I've performed a factory reset on the router, so it is ready to be configured as a new router on your network.

The auction includes the router itself and the power supply with cord.  Unfortunately, I don't still have the printed documentation that came with it.  However, you can find information about the router and how to set it up at the following Apple support pages:

• https://support.apple.com/kb/sp672?locale=en_US
• https://support.apple.com/guide/aputility/set-up-a-new-base-station-ap36841/mac
• https://support.apple.com/en-us/HT201945

By default, I'm not including any Ethernet cables.  However, if you need an Ethernet cable to connect the router to your modem, let me know upon purchase, and I can include one upon request.
