I just got a nanostation M5. It turned out to be an XW model. I flashed it with AREDN 3.15.1.0. I racked my brain for hours trying to get it DTD'd to my 2.4 and 5 GHz nodes. It might be well known to some here or it might be a fluke, but I discovered quite by accident that my Nanostation XW M5s dtd link on the secondary Ethernet port but will not link on the primary. Just a heads up in case someone else gets a node that links this way.
