I have a Mikrotik setup with hotspot and two ubiquity antennas for WiFi distribution at a camping place.

Everything is working more or less but now I have a client that want to use his Xiaomi router 2 as wireless repeater at his plot as WiFi coverage is weak there.

I note two weird things:

1. I can't find the Xiaomi router in the DHCP server leases
2. I can find it in the host section in hotspot, but it's MAC get repeated two times...

I wonder how do it reach the hosts section without being at DHCP section (and no, it has not fixed IP, it's DHCP enabled)?
And also wonder why it gets two hits with the same MAC, one marked as "D" and the other one as "A D"?

Any idea?
