How To Use the AirRouter Ports

Here is a picture of how you can use the AirRouter or AirRouter HP ports.
​The lower power AriRouter is powered by a wall wart and barrel connector, while the higher power AirRouter HP is powered by the PoE injector.

​Please note that if you want to connect the AirRouter HP to the Internet, to to another network, you must:

  1. Connect the PoE port of a PoE injector to the WAN port of the AirRouter. This supplies power to the AirRouter and enables connectivity to the other port (LAN) on the PoE injector.
  2. ​Connect the LAN port on the PoE injector to your Internet or other network router.

​Please also note that Port 4 on the AirRouter is only used for Device-to-Device (DtD) connections to another AREDN node.

Uploading firmware to Ubiquiti


Warning AirOS 5.6 and newer

(September 2015)

Do not flash a Ubiquiti device that is running, or has been running, airOS version 5.6 or higher with AREDN firmware. We have become aware of a change that may be incompatible with current firmware images. We are looking into the concerns raised and will post more details as they are determined.

* Are you using a supported device? Just because the device was made by Ubiquiti doesn't mean it will be able to be flashed to use AREDN! See the Supported Platform Matrix before continuing. *

Understanding VLAN's

All this talk about VLAN's!  What are they?  How do they work?  Wikipedia's definition ( is:

This is usually achieved on switch or router devices. Simpler devices only support...
