EdgeOS firmware can be downloaded from the Ubiquity download page. First we need to see the installed version.

I like EdgeOS because you can pull the image directly into the router via HTTP. Alternatively you can download the image into a local webserver(like I did) and install from there. After the download is complete installation will begin.

The image has been installed but its not running yet, we need to reboot the router for the new image to become the default.
admin@ubnt:~$ show system image The system currently has the following image(s) installed: v220.127.116.1177648.140620.1301 (default boot) v18.104.22.16874253.130626.1248 (running image) A reboot is needed to boot default image
Simply reboot and the new image will become the default boot.
admin@ubnt:~$ reboot Proceed with reboot? [confirm]
Verify the router is running the recently installed image.

EdgeOS can store two images in the event you need to revert to a previous version.
admin@ubnt:~$ show system image The system currently has the following image(s) installed: v22.214.171.12477648.140620.1301 (running image) (default boot) v126.96.36.19974253.130626.1248
You can also delete one of the image.
