 Step 1: Preparing the device
   Before you install AREDN |trade| firmware on a Ubiquiti 802.11ac device, you must first make sure it is running version **8.7.0** of the standard Ubiquiti AirOS software. This procedure will not work if the device is running any other version. Fortunately you can upgrade or downgrade the standard software.
 
-  As described above, it is best to connect your computer to the device using a simple Ethernet switch so that your computer's network interface remains unaffected by reboots on the radio. The IP address for a new Ubiquiti device is 192.168.1.20. Set the IP address of your computer to 192.168.1.10 and, when the device is powered up, enter 192.168.1.20 in a web browser. For a brand new device you’ll be asked to select your country and agree to the EULA. Then click *Continue*. Next you will be prompted to create a user account and password on the radio. You can enter the username ``admin`` and the password ``admin!23`` (for example) and then click *Save*.

   You should now see the main Dashboard view in AirOS. On the left, click the *Gear* icon. This will take you to the System page. At the top of this page you will find the radio's current firmware version. For example, it might read ``FIRMWARE VERSION XC.V8.7.1``. If the firmware version shows either **XC.V8.7.0** or **WA.V8.7.0** then you have the correct AirOS software and can move on to **Step 2**.

   On the top right of the System page you will see “UPLOAD FIRMWARE” and UPLOAD in blue. Clicking the blue UPLOAD text will open a dialog and let you select the **8.7.0** firmware you downloaded to your computer. Now that firmware will be uploaded to the device. Once completed a dialog in the top right will be displayed allowing you to either UPDATE or DISCARD the newly uploaded firmware. Click *UPDATE*. The upgrade process will now start. Do **not** unplug the device until this step is completed.
 
-  Once the upgrade has been completed, the device will return you to the login page. Log in using the username and password set earlier (``admin`` / ``admin!23``). Once again you will see the System page and if everything has been successful, the firmware version will now read either WA.V8.7.0 or XC.V8.7.0 and you can move to **Step 2**.

 Step 2: Copy the AREDN |trade| firmware to the device
-  Before you can install AREDN |trade| firmware on the device, you first need to put the AREDN |trade| image in the device’s ``/tmp`` directory. Note that each 802.11ac model will have a *different* AREDN |trade| image name, as opposed to currently where one AREDN |trade| image may support multiple models. Be sure to download the correct firmware image from the AREDN |trade| download site. Copy the firmware to the device using the scp command:
