It works well. The speed and latency are stable, but my real traffic is not more than 150Mbit/s.
I had a few kernel failures on the station side, sent a ticket, but so far support did not find something wrong.

We had a kernel failure on a SXT AC SA. Sent supout.rif. Now it runs for 6 days.
So maybe hard to find.

I guess it happens very rarely. At least I am not the only one, because support suggested it could be hardware, but I doubt it - I have boards with hardware problems, but they just reboot and the message in log is only "reboot without proper shutdown". The most recent time i had "kernel failure" was on v6.15 and it was fixed in next version and again it happened only on nv2 links on the station side.

How you configured link?
as wds bridge?

Did you noticed, that NV2 eats cpu more than plain 802.11??
eg. under no load cpu usage with NV2 shows abou 10-12%, when with plain 802.11 only 1%

First i configured it as station-bridge, but then changed to station-wds to see if that may be causing the kernel failure.
I know that nv2 eats more cpu and that is expected, because the tdma part is done in software. The cpu load with my traffic varies 30-40%. 802.11 in situation with many packets has high and unstable latency.

Today another sxt ac hangs and needed a powercycle. Plugged in a 750up now for remote power reset.

ste,
Please provide us with support output file (support@mikrotik.com). As well provide us with more information about the issue and what happened.

Any update now that 6.19 is released?

What's new in 6.19 (2014-Aug-26 14:05):

*) wireless - improvements for nv2 and 802.11a

I'm wondering if nstreme is good now. I prefer nstreme over nv2 for ptp for low latency.

The good choice could be mANT30 instead of Rocket Dish.

Cetalfio

It's the true, I have both, and mANT is more better made and have better performance.

Now this is interesting... I am not a fan of ubnt, so would indeed cheer if it can be proven that mANT30 is better than Rocket Dish. But can we see some real test results? Because opinions based upon some wistful thinking are no good to no one. But if you can show us that these antennas really perform better (show us the differences) I am not to shy to link to this test whenever appropriate just to show that ubnt is not as good a brand as they do want to make people believe.... ("carrier grade" )

I'm not hateful of ubnt myself, I like their M series APs and CPE quite a lot and am pretty happy with them. I have had great luck with the RocketDish30. That said, nstreme is superior IMHO to airmax for ptp links and I like the idea of a NetMetal5 w/ mANT30 if they are indeed superior to a RocketAC-Lite (or upcoming RocketAC) + RocketDishAC or RocketDish30. Sometimes I feel that I'm 1-2dBm short of advertised gain on the RocketDish and I suspect the feed horn isn't as good as it could be.

Here are the latest results from me:
Link distance 46 km.
Antenna - 140 cm parabolic dish - double pol.
Cable leght 2x4 m
2x RB921UAGS-5SHPacD
and very noisy environment

What is this Antenna - 140 cm parabolic dish - double pol (Manufacturer)

I'm also interested

Did anyone ever figure out what dish us being used?

i have NetBox 5 (RB911G-5HPacD i can't select channel when i going to select channel than show error can't select chennel please wireless info ..no highlighted any channel
