ARM devices and NV2 protocol

Fri Jun 22, 2018 4:25 pm

Hello,

we are experiencing problems with NV2 protocol and ARM devices (LHG AC, SXTsq AC, Disc AC). We have two testing setups:
1) PtP link with 2 LHGs AC (bridge mode, ROS 6.43rc29) - with 802.11 protocol we have 90/90 Mbps (download/upload) - limit of 100M ethernet on both ends, tested from x86 router to another x86 router (in between only two LHGs). When I changed to nv2 protocol (did not touch any other settings) throughput is not stable, as per image
LHG1_2_bw_test.png
2) PtMP - AP RB922, ROS 6.42.3, 7 clients. One of out technitians have his client device (SXT AC, ROS 6.41) and we mounted LHG AC (ROS 6.43rc14) next to it. Results:
20180522-client1.png
20180522-client2.png
We reported this problem to Mikrotik but no solution at the moment.

Does anyone have similar problems with ARM devices?

We have the same problem with SXTsq ac clients.
Fix it!

Because Disc lite5 have problems with radom viewtopic.php?f=3&t=134594&hilit=disc
now we use DISC lite5 AC and we have the same problems with NV2. We use NV2 on all sectors in our network. Low P2MP speeds (unstable) is very big problem.
ROS 6.42.4 not solve it !

P2P links with nv2 also works slow [Ticket#2018042522004921]
Ticket opened 25.4.2018 - no solution yet :-(

@Mikrotik When do you make the update for ARM? Thanks

This problem is know about 6 Month old, we sended all ARM ac devices back to Distribution and stock a lot of old ones.

Now we are seeing that SXT ac and SXT HG ac are out of stock at our distributions and another distri has removed them from shop, looks like these are going to be legacy’s.

But the bad news is that the new ones still not working!

Hi,

Ignoring the performance issue on this, I have stability issues with ARM and NV2. On my SXT SQ AC box my NV2 link stays up for about 3 to 4 days and then the entire system reboots. I believe this was meant to be fixed with 6.42.4, but it obviously still seems to be happening.

Anyone else having this issue with ARM and NV2?

Thanks,

Chris

I confirm the problem, here a print screen on the same AP an LDF with better signal as worst perfomance than an old lite 5 N.

any update? ARM devices are not usable at the moment in the next months we have to deploy something like 200 new customers and we need a solutions that wokrs like SXT 5 lite ac

Thank you

Maybe is an hardware problem: NV2 needs an accurate timing and the bad performance seems to be caused from antenna loosing the Nv2 slot. It's not an RF hardware related problem beacuse it work with 802.11/nestreme.

No words from mikrotik and no old SXT AC lite available it's pain for me :-(

Yeah, NV2 doesn't work with 802.11AC :(

Hi guys it's not a joke SXT AC lite is no more available and new arm hardware with NV2 don't work.

Mikrotik please let know us something

HELP :-(

What if you compare it with ARM and 802.11 protocol (not NV2), what is the speed then?

Normis in 802.11 works like a charm :-)

In NV2 seems that antenna has timing problem loosing the slot

Re: ARM devices and NV2 protocol

then why use Nv2 if you have better speed than non-ARM with nv2 ?
Nv2 was made when devices were different and needed optimisations that are no longer needed. Maybe it is simply time to use 802.11 in the new devices.

you want to say if I have all devices in network in NV2, I need to switch to 802.11 ? You understand what you give bad answer ?
After your answer, I think many have the thought that you can not just make a correction of errors. you release a notoriously bad devices and you cannot change errrors...

Very very bad answer and very very bad devices lately ....

I understand that mixed network might have compatibility problems, you have a good point. Have you considered to switch them all to 802.11 and seeing if you don't get better results than Nv2 ?

Normis 802.11 is not efficient like NV2 in noisy enviroment and on busy AP and it not solve the problem of hidden nodes. Are you saying us to switch to 802.11 when you released some months a go GREAT improvments to NV2? WOW I am without words....

We install something like 800/1000 new customers per year and we need to have back an antenna that work well with NV2.

Nv2 is the core of our business for many of us we can't switch to 802.11!!!

Please give us back the SXT lite 5 AC

Normis we need it urgently we have no more stock and we need 200 for the next 2 months

You are killing small WISP that developed the access network using NV2

Our competitors uses ubiquiti and they not have this kind of problem we have no chance to install new customers so we 'll loose market, it's a disaster

We are working on the solution, I am simply asking to evaluate situation when using 802.11 and then see if Nv2 is needed at all. If not, you can already expand your network. If yes, wait for the fix please.

Absolutely agree! We, too, the whole business is built on this, and at first the problem with the devices "DISC" that burst like popcorn, 40 devices for 2 months were dead, and now - this problem with the new antennas. Just awful ....

60Ghz progress is amazing.

In 5Ghz I am very hopeful we can see NV2 matching AirMAX and AIP performance.

We don´t have time for hope......
The Business is changing fast, and with devices that are 6 Month old and still in "Beta" we can´t do business case, or what did you think?

60Ghz Devices are great, but there are a lot of old cases

UBNT? :lol: :D :lol:
If serious, we switch some sectors with SXTsq CPEs to 802.11 until nv2 will be ready again. But it's difficult to manage mixed network, and we have small access network for now.

We work in very noisy enviroment using QRT or SXT AC as AP, every client has SXT + 60cm offset dish. The main problem for us is the hidden nodes. In peak time with 802.11 we have serius problems with collisions with clients sometime dropping connection on the AP, nstreme works better than 802.11 but the best for busy AP (30/40 clients) is NV2. We reach 60 max 70 mb/s per AP.

So we need NV2 working on ARM devices

Why not do some improvements with nstreme (the old one) ?
In noisy environment it works better than nv2 in many cases... If it works well with arm, why not?
(at least until NV2 got fixed)

easy for us, the saw the issue in Q1-18
and it happened nothing, we send back all arm devices, now our mikrotik stock is empty no new MISPBE,
and we begin to buy other vendors, since MT has no working solution for us.

We did make changes, tested them, they were not enough, so we continue testing, so that the release has a bigger impact. We want the fix to be good for everyone.
