buy UBNT or Mimosa, do the same as your competitor....
Use Mikrotik for Routing and something else for Wireless ....

Re: ARM devices and NV2 protocol

Hello Folks!

Any solutions yet ?

We could not upgrade higher than RoS6.41.3, except for wired devices like routers and switches, all versions after simply renders 802.11 and NV2 to useless, nstreme is not tested.
We have a lot of SXT, SEXTANT, RB411 plus some other variants and lately also QRT-5, Dynadish5.

The issue above only affects AC (or ARM / AC ?) devices I think.

It affects ARM Based AC devices, MISPBE Devices are legacy now, you can only buy residues

Hello Normis!

When will the fix come to "current" ?

It is not affecting only AC.

It affects also 802.11abgn

And NV2, using 20MHz bandwidth with classic RN52 wifi boards in RB411 which is so common in our links here...

Network links simply stalls after little traffic and the devices becomes so loaded they are not possible to login to anymore.
Rollback becomes tricky, at least for remote wireless CPE devices, you need to bring them home and netinstall them for a rollback.

We have a lot of MIPSBE devices in production for the past ten years, cycling them out is in progress but it will take long time, we replace only failed devices.
So a fix for MIPSBE would be nice, however they work with 6.41.X and bug fix only, and we will not hesitate to update anything that works.
Just hoped to being able getting more performance out of NV2.

Thanks Normis. Great effort from the team at Mikrotik.

I am looking forward to testing NV2+ARM performance on the OmniTIK 5 PoE ac2 ;)

Why do not you believe in them? :P
They don’t in competition to UBNT, there are only low cost 5ghz / 2 GHz Devices, with Cheapest chipsets, and a lot of missing features in ROS over years...
I don’t believe that there ist a Business Case for WISP Hardware in Mikrotik Future...

We tested recently a 5km link with RF Elements TP 550 Dishes
Mikrotik M11g + R11e-5HacD
Rocket PRISM 5ac Gen2
Mimosa C5C

And the worst thing in Latency, Spectral usability, and Transferspeed you could buy is Mikrotik

One light in the Tunnel is LHG60 but it needs better Design....
Better Pole Mount with precision adjustment
Solid Dish with Randome for better rain/snow survival

Mimosa is special case......
Sometime UBNT works better sometime Mimosa, depends on Spectrum, Mimosa is great for P2P if you deliver Voice-Service.
The Latency on Mimosa is 100% stable..... great TDMA implementation....

If seen the Dome und Mount from my Polish Friend, but why did MT no deliver something like that?
The engineers were in hibernation?
I Think there is only one Reason, LowCost!
And it ended in the Software mess we are now, ARM 5 Ghz Devices are now available for 7 Month, and there is still no solution.
CAP AC Performe better with the latest Software, but it is still behind competitors Performance.

Give us more details, what is not working. The RC contains a fix for the issue, that helps a lot of people, so if it doesn't help you, please post specifically what is wrong, what signal you have etc.

Hi, in my case with a good signal on arm when going from 802.11 or nstreme to nv2 the level of ccq falls and the link appears at 6mbps. It goes back up to 90% and then falls again continuously when passing traffic. In 802.11 or nstreme it is stable.

Thats not the case
Throughput and latency are the problem
but until we removed all ARM i´m not able to test in real environment

We have exactly the same problem, for some reason seems that the arm device go out of NV2 slot.

Here a speedtest from 2 clients on the same AP, the AC device is stable the arm device no, 20 Mhz channel dynamic downlink, tdma period size 4ms, ac device has a worst signal than arm

It is better. N 911G to sq ping is stable and stable 100mbit to sq. But. For waiting i thing u should give level 4 for all devices for micro bases. As other folks told ya, to much time waiting. Seriosly. Fix downlink- 65 mcs default, tdma auto.

We have 6000 cpe deployed 98% mikrotik based we have a lot of experience with wireless.

Arm devices issue seem to be a timing problem with NV2 every new arm device you add you have exponential increase of problems on the AP, it's a big problem on busy AP

Yes, of course. We have multiple anechoic chambers with robotic installation stands with tens of CPEs mounted. Seems that some situations are simply unique

Many times its working much better than NV2...

I don’t think you will see anything from Mikrotik in Wireless Market, Wireless is dead end, FTTH is future, look at the Products MT is releasing, look at KidControl.

Thinks you will not see:

- GPS Sync
- Spectral Scan
- TDMA Protocol like competitor have
With small Latency and high throughputs

There are no innovations for a long time, ROS is just patched around it.
For us Mikrotik is in dead end with Kernel 3.xx.xx


The way you could go is not longer stay with MT, or waiting for Christmas

So maybe some tests with the agressive ap on the same channel. And little more precision on fix downlink to cpe. Cpu on bridge can handle it.

Nstreme works fine in 15 times hardware retries and dis timeout 00:00:15 long guard msc11-12-13. But i thing with ac nv2 1ms it would be stable 200mbit. When? ;)

I hope you have not considered it resolved because it still does not work. It's a pity being such a good product that it does not work. Finally we will have to return several units.

Your Problem would be that older SXT AC / Lite AC / HG AC are not longer available.....
And after 8 month of "Yes we would fix it in next RC"
These are the Solutions:

1. Buy SXTsq with N Only instead of AC (doesn't ARM based)
2. Look for used ones
3. Buy another vendor

shame on mikrotik,

Hello All,
as most of you I also have several problem using mikrotik arm ac devices. I'm testing a 12km bridge with a couple of LHG XL 5 ac configured to make a ptp link. They comes with ROS v. 6.40.3 and this version didn't work at all. Since then most problems was fixed in later versions, but not all. I performed many tests and sent to Mikrotik support. They answered each mail, but unfortunately I have no explaination of problems (software or hardware?) and no solution. Now I want share with you my results, testing 6.43RC45 in a clean environment. Summarizing:

- 802.11n gives always the best performances compared to any other mode and protocol (NV2 / AC)
- without other sources of interference, NV2 is close to 802.11n performances (but in a noisy environment 802.11 is better)
- on some frequences the signal strenght falls by 10dB (from -65 to -75). Why?
- on some frequences the bandwidth test shows a periodic up and down behaviour (5620, 5660, 5680) Why?

like many of you, I'm also worried about the situation, since I have to put twenty bridges and I do not have a reliable device yet. I hope the solution will arrive soon. Any predictions Mikrotik?

Nice solution :) but only for P2P.
But we need clients for our network based on NV2. No products based on N are on the market now (disc, lhg, sxt) in Czech republic. Only AC harware is now on the market. So we need to use AC harware. Stalemate... :(

Hello everyone! We are following this topic from the beginning because we also use ARM equipment in our network.

We have this link of about 1km.

Using NV2 protocol, the results are pretty bad.

Already with the 80211 protocol, we achieved a better performance.

Hugs to all.
