Well yes. Off course. The link is 12km.
I spend yesterday and last night at least 4 hours in resetting (both ends) re-configuring and re-setting again.
I found that sometimes the radio’s just stopped working if too many changes in the configs were made.
I’ve had it twice that a radio did not work after picking a new frequency or on a certain config. Than did a sys reset followed by a power cycle and put the backup back with same config and it did work! Strange behaviour…
Anyway, I’ve got it now running. 12km link with 27dBi antenna on both ends. Signals in the -35dBm range but sometims I see -5!
Manual power settings are also not very accurate. The difference in -23 or -24dBm gives 10-15dBm difference in signal at the other end!
I set now power levels such that on both end signals are around or just under -50dBm (signals fluctuate 2-4 sometimes 20dB!).
Running tcp bandwidth test over the link from CCR to RB1100AH gives me 60-65Mb sustained aggregated througput with almost 100% CCQ. Connection rate is shown as 150/150Mb and stable.
I have 40Mhz-below channel selected from channel 14… (!)
I am very pleased with the result of this link since it runs first 50 meters flat over a roof with antenas and chimneys. Than inbetween two other buildings a than at least 500 meters over appartment blocks. If I run a scan I pick up almost 100 wifi routers! Some give me signals better than -50dBm! Still the link rocks… 
I don’t know what happened yesterday, but the units have been running for an hour with a full load of traffic and didn’t drop anymore…
The very impressive results make me think of setting up a dual chain link. See what my througputts will be in that case…
(So, who was thinking 2,4Ghz is a lost frequency for WISP’S? I have more problems to get a 5Ghz backhaul to run between the same towers as this 2,4Ghz link. I hope MT still will bring new 2,4Ghz units on the market…
