after replace cAP lite with cAP AC i must say its shit..for now i cant get more then 60Mbit on 2.4GHz and same speed its on 5GHz.
6.42rc30 works better in some ways, time to time i get 200Mbits this speed its not stable.For no reason slows down in time.
I have similiar experience. Speedtest.net shows ~180mbps gradually settling on ~80mbps or worse; iperf3 shows even less impressive numbers
I did some comparisons between cAP AC and my good old hAP AC.
Test conditions/parameters:
802.11an two chains (My Lenovo T420 laptop doesn't have 802.11ac)
hAP AC was running 6.40.1; cAP AC was running 6.40.6
Both hAP AC and cAP AC were running virtually the same wireless interface settings:
On cAP AC:
set [ find default-name=wlan2 ] band=5ghz-a/n/ac channel-width=20/40/80mhz-Ceee country=lithuania disabled=no distance=indoors frequency=auto mode=ap-bridge rx-chains=0,1 \
security-profile=profile1 ssid=CAP5 tx-chains=0,1 wireless-protocol=802.11
.
On hAP AC:
set [ find default-name=wlan2 ] adaptive-noise-immunity=ap-and-client-mode band=5ghz-a/n/ac channel-width=20/40/80mhz-Ceee country=lithuania disabled=no frequency=auto \
mode=ap-bridge security-profile=profile_lukoramu ssid=MTLR wireless-protocol=802.11
.
Both chose the same frequency (5180MHz). I kept only one AP turned on at the same time, so no interference between them.

Thoughts? Ideas?
Maybe it's a compatibility issue?.. Tomorrow I will do the test with a newer laptop, which has an AC card..
P.S. I noticed a big difference in Tx/Rx signals too (see above)
