Their software It's incredibly powerful, but also quite opaque to someone not into hardcore networking. I setup a small private WISP using their gear and configuring it was pretty rough for a non networking nerd. It's not running Linux, but a custom OS. The quickset is handy, but as soon as you want to do something slightly different, you're up to your neck in low level config. Still great HW and if you know how it can do everything you need. Ubiquity gear has a friedlier interface.
