Hello,
This is my setup:
AP: 433AH, R52nM and parabolic 90cm dish 32dbi antenna, 5GHz-only-N, 20/40 eC, nv2 wireless protocol, one chain,
Client 1: 433AH, R52nM and parabolic 90cm dish 32dbi antenna (17km distance in winbox) - signal Tx/Rx: -65/-65, ccq Tx/Rx: 70/90%, SNR:50db, Rates: 135Mbps-40Mhz/1S/SGI
Client 2: 433AH, R52nM and parabolic 90cm dish 32dbi antenna (19km distance in winbox) - signal Tx/Rx: -68/-66, ccq Tx/Rx: 70/85%, SNR:50db, Rates: 120Mbps-40Mhz/1S/SGI
with those signal levels and ccq i expected more throughput then using old 802.11a turbo mode where i had constant 40-50Mpbs TCP measured in bandwidth test, now i have 30-60Mbps which changes rapidly. I suspect that my nv2 settings, which was default (2ms, 40km, 50% dynamic downlink), is bad so i changed it. I tried to lower cell radius to 25km, tried higher radius to 50km, tried TDMA timing from 1ms to 10ms but each settings didn't give satisfy result, worst result was on auto. I also tried 802.11n but then bandwidth test shows just 10Mbps TCP??! Now i set 3ms and 30km, downlink is on 60% where i am getting 30-40Mbps stable but problem is when i am pinging client 2 from client 1 or vice versa, there are too many timeouts, sometimes Winbox won't access client 1 or keeps disconnecting form client 2 etc.
Can you help me to make those links more stable and gain more bandwidth with this setup?
Thanks
