Hi guys,
We are here with George from Sarantaporo testing this UniFi AC Mesh devices.
We successfuly flashed two of them that are meshing with each other and with other devices through 2.4ghz and 5ghz with AC.
The problem is that the throughput is not very good.
Doing a netperf, we get (on the AC link):
root@LiMe-3c5540:~# netperf -H fe80::f29f:c2ff:fe3e:5435%wlan0-mesh netperf -cCD1 -t tcp_maerts -l30
MIGRATED TCP STREAM TEST from ::0 (::) port 0 AF_INET6 to fe80::f29f:c2ff:fe3e:5435%wlan0-mesh () port 0 AF_INET6 : demo

87380 16384 16384 10.06 55.41
and on the 802.11g link:
root@LiMe-3c5540:~# netperf -H fe80::f29f:c2ff:fe3d:5435%wlan1-mesh netperf -cCD1 -t tcp_maerts -l30
MIGRATED TCP STREAM TEST from ::0 (::) port 0 AF_INET6 to fe80::f29f:c2ff:fe3d:5435%wlan1-mesh () port 0 AF_INET6 : demo

87380 16384 16384 11.88 1.19
So... pretty crappy, isn't it? (the devices are 30cm away from each other, and no wireless traffic is around but those.
Also, another thing called my atention.
These are the luci wireless outputs for both of the devices.
Isn't it strange that both of them have high reception speed and super slow transmission speed with each other?
We have already tried changing the channels.
Also tried to avoid 11s/adhoc and connect as client/master.
The outcome is the same:
root@LiMe-3c5540:~# netperf -H fe80::f29f:c2ff:fe3c:5435%wlan0-1 netperf -cCD1 -t tcp_maerts -l30
MIGRATED TCP STREAM TEST from ::0 (::) port 0 AF_INET6 to fe80::f29f:c2ff:fe3c:5435%wlan0-1 () port 0 AF_INET6 : demo

But maybe there is some knowlege in the group that can help on this.
What do you think about this?
