Hi, In the network of buenos aires cauca Colombia, we decided to implement some equipment at 5GHZ and we have some problems: 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. Fernando Castro T
