I have been configuring a 5Ghz network with LibreMesh, I have several Ubiquiti Nano M, NanoBeam and NanoLocoM nodes.

It turns out that one of the NanoBean devices connects to 2 nodes with good signal quality, between 90/90 but when I try to access this node it is too slow and if I ping the device the answer is with DUP:

PING 10.17.177.80 (10.17.177.80) 56 (84) bytes of data.

64 bytes from 10.17.177.80: icmp_seq = 8 ttl = 129 time = 675 ms

64 bytes from 10.17.177.80: icmp_seq = 8 ttl = 129 time = 675 ms (DUP!)

64 bytes from 10.17.177.80: icmp_seq = 8 ttl = 129 time = 1163 ms (DUP!)

64 bytes from 10.17.177.80: icmp_seq = 8 ttl = 129 time = 1171 ms (DUP!)

64 bytes from 10.17.177.80: icmp_seq = 8 ttl = 129 time = 1679 ms (DUP!)

64 bytes from 10.17.177.80: icmp_seq = 8 ttl = 129 time = 1684 ms (DUP!)

Any ideas to try to solve it?

I am using LibreMESH with bmx6 and the mesh mode is 802.11s.

Any help or idea I would greatly appreciate.

Greetings.
