No XW on 900Mhz, 2Ghz, or 3Ghz devices. Strictly an issue on "NanoStation M5 Loco XW", "AirGrid M5 XW", "Rocket M5 XW". There is only one exception, the "Nanostation M5 XW" is supported and working. Ubiquiti changed up the network port hardware on this device and does not suffer from the same problem, but has different assignment of LAN, WAN, and DtDlink across the 2 physical ports, due to its own quirks.
