Having upgraded our first nano (Nano M5 running XM-5.6.3) and put it into NAT mode, the unit requests a dhcp lease from MAC 02:FF:FF:FF:FF:FF ( on the 'Separate Wireless Management Interface')
I will be using PPPoE going forward so I would need the mac of the management interface to be unique...
I've been seeing this happen as well. It seems to only affect some hardware, and as far as I can tell, it's pretty much random - some work perfectly normal, and others will consistently show up as 02:FF:FF:FF:FF:FF (and all get the same IP from the DHCP server, because of that)... I'm assuming it's something specific to that particular piece of hardware. So far, I've only seen it happen on XM hardware, so I'm not sure if XW is affected.
Let me know if there's anything I can do to help, as I would like to get this resolved... I could probably even send Cambium an affected radio, if they're having problems reproducing it.
For what it's worth, this happened on every XM radio I elevated with 3.2, but it's only happening on about half of them with 3.2.1 - I'm not sure if that's just a coincidence, of if 3.2.1 partially resolved it... I haven't tried upgrading any with the problem from 3.2 to 3.2.1 to see if that changes anything yet.
Yes, the MAC addresses on the Eth and Wireless interfaces appear to have the proper format. I did just notice that they're showing the same MAC address for both ethernet and wireless, but that seems to be the case on units that aren't affected as well.
Not every XM unit is affected - roughly 50% of them work fine.
