ARM devices and NV2 protocol

server8 · Tue Oct 23, 2018 9:08 am

Yes but I don't want to install new towers and after some months have the problem solved or new AC working hardware. NV2 works great with old AC hardware.

It's important to have an official answer from mikrotik about this iusse.

It's a Big problem but... If @Mikrotik dont solve the problem It is very dangerous not change the brand...

cpetey147 · Tue Oct 23, 2018 4:03 pm

It's pretty sad and unfortunate that mikrotik won't even comment on this. Do they not care about keeping customers? If they would just comment an ETA and live up to it they would keep far more customers than their current scheme. We were making a giant push towards tik ac when these came out but now we have hundreds of these sitting in our warehouse with no response from tik besides ooooooo try the latest firmware that doesn't do anything.

Alessio Garavano · Tue Oct 23, 2018 4:40 pm

I pay the grill when Mikrotik answer and solve that problem!

I have some used LHGac, SXTsq ac, we took down in the last weeks, because of
unsolved problems with ARM Boards, if someone want to get them, feel free to ask,
otherwise we throw them away.

can you send me a mail to miko.sakic (at) gmail dot com? i can't contact you on here.
thank you.

rc45 contains Nv2+ARM fix. It will be released within the next 24 hours.

Hello Normis.
Latest firmware not solve NV2 problem (missing slot). Since 13 July 2018 you do not write. Can you comment on the situation?
Silence will not solve the problem ...

Another interesting Feature arrived, a few rb411 reboots themselfes nothing in logs no supouts just the message u get when unplugging the power. So it is Some kind of crash.

Why this in this topic?

I have tried SXTsq 5 ac-US firmware 6.42.9 connected to an hap ac lite firmware 6.40.9 in channel 5180,5200,5745,5750 for an hour with no disconnections.I used protocols nv2,nstreme,802.11 20/40Mhz Ce.

There are options why it take so long...
1. Hardware issue, no fix is possible
2. Driver Issue but fixable only with newer Kernel, wait for Ros 7 it will arrive on Chrismas, but you don’t know the year

Better no roadmaps/timelines/milestones, than promised but not fulfilled roadmaps/timelines/milestones. They learned from the past and I must applaud for that.

On the other hand I fully agree that in some situations, statement about "why is there an issue and what are we going to do" would be better (just explanation and course of action, no timeframes). NV2 on ARM is one of these situations which would deserve such statement.

I do not know why MIKROTIK chose the strategy of silence? ARM and NV2 is a big problem. Just if they wrote that it will be fixed in V7?. Or, in another hw revision will be fixed.

Do we stop buying AC hardware? This is solution?

Mikrotik Wireless is more then outdated and the most Problems are ROS based, or say based on the own Wireless Drivers they use,

YEP 1K Euro 6 months ago wasted for DISC/LHG/SQ ARM. Mikrotik sell me broken products & use my money for develop "kids controll" &many idiotic features. I Don't buy any ARM from 6 month, only classic LHG/SQ. NOW almost ALL links p2p changed for UBNT airfiber5 &works like charm. Only p2mp still mikrotik because can't easy migrate.

NOW 6.44 Beta 40 / 6.43.4 ARM family all AC products:
1)NV2 broken because half speed (all mikrotik NV2 platforms are slow but NV2+ARM slow like RB133C CRAP)
2)802.11 sometimes random latency spikes on all ARM AC brides/apclients/NAT/router no matter

This ARM hardware have powerful possibilities but mikrotik don't want or cant develop ?
Maybe mikrotik gave us exchange program one used LHG AC for classic old LHG ?

We are close to a solution to the Nv2+ARM performance issue, please hold on for a day or two, when we will release the changes in RC release chain, for first testing.

Close enough or is this cold case closed, like Spectral Scan?

honzam · Wed Dec 12, 2018 8:57 pm

We have a Big problem, please @mikrotik solve. If need something of user mikrotik only need sais us. We are wisp and nedd solutions. @mikrotik is not other bad brand...

We are also WISP and we are dealing with the same problem. I think it's about a large number of WISPs and @Mikrotik does not solve it anyway...

Mikrotik does not communicate, does not solve...

Do you think we can expect the problem to be repaired in 2019?

Hi guys. Yes wireless situation is annoying. But this is still a MT forum. This should not be used to praise other vendors. So please consider removing your posts with foreign gear.

MT is great with routers.
MT is great with their new 3xx line switches
LHG60 is great

mikrotik has caused me many problems and does not solve them. some things work well but many do not. We have lost a lot of time and money because of the mikrotik arm. If mikrotik does not want to solve the problem we have the right to look for arternatives. In my country it is considered scam to sell products that do not work. Also mikrotik does not respond to problems.

B5 is the best for PtP link, 1Gbps full duplex.

The same will do AF5xHD and will cheaper with antennas x2

Everyone always has the free decision to buy anything. If a product does not work as *advertised* just give it back.

If you loose money using a product which is not developed further and does not work great ... it is your business decision. If you expect help from a vendor using his products this is your right. But a vendor is not committed to do this. Buy a cisco and call them for help. You will end up at sales offering you an expensive contract. If you want updates you need a contract.

So dont whine. Order equipment from a different vendor, test it and use it.

This nv2 situation is for so long now. Everybody whining *now* likes to whine or does not understand how to do his job. As you see this thread is still here and everybody is able to read and see the limitations.

Despite all of this: This is still a MT forum and not the presentation place for other vendors equipment. Just follow the board rules.

802.11ax may change things

802.11ax is useless without Software revolution, but with the delay they have had for AC, we would probably see AX in 2021, ROS 7 could be available.....

Why not discuss alternative? They don’t answer anything, so I think they don’t need to sell 802.11 Hardware anymore, and that is what I said more then 18 month ago, they did decide do only low cost Outdoor Wireless, and don’t invest time in Development.

Mikrotik is more going for routing, switching, Fiber not for wireless.
But doing such decision without telling customers is more than contempt

Mikrotik despite doing not enough for nv2 was the first wisp vendor offering an .ac product. Problem with .ac and tdma protocols is that the common cpus are to weak. Vendors who offer better .ac experience for wisps do this by making HW modifications or complete other chipsets. MT uses what their favorite chipset vendors are offering. 802.11ax will have some stuff integrated into the chipset which will help wisps. So this might change things a bit. And as you see with 60GHz. Where are your favorite vendors there.

Because it is a MT forum? Think of your users talking on your forum where to shop else.

This is not the truth. Look at LHG60. And there is still place for MT 5GHz where it does not need to scale. Hardware is very reliable. And SW features are very good.

Mikrotik again sell beta / alpha products & promised to solve the problem fast. They lie again & play on time. Now after months can't send back because have only 14 days in my country for this. The only way to defend a good name is to fix it. No fix = no buy & black PR from me.

The first big lie and time game from mikrotik is the first generation of AC:
1)Still unstable if use IP firewall & priorities for WMM pure 802.11 (watch dog reboot sometimes)
2)Still NV2 works worse than older generation for 802.11N mode not AC !
3)Still no Spectral scan....

Better sell old good hardware like Cambium.
802.11N from mikrotik & NV2 works great & beast Vs noise from another networks.

I was expecting response to mfr476 would be:

Hi mfr476,

We apologize that the product is giving you such a headache. We understand your pain and currently we have our top techs on it. This issue has been escalated to our highest level. We already assigned 80% of our engineers to work on the issue.. Unfortunately, we are still looking for solutions. We currently are having issues with 1. ex. 2. ex 3. ex.. and If we still can't find a solution in another month we will be asking assistance from ________ ( a more exp company or engineer ) to solve the problem.

An update every now and then would be nice as it gives your customer a sense that you are indeed are working on the issue but is facing some roadblocks.

But that's just me.

Please contact MikroTik through official channels if you would like to get "customer support".

MikroTik is well aware of Nv2 issues with ARM devices, but they are not easy to solve, because new chipsets are fundamentally different and Nv2 was made in times when there were different chipsets, different wireless standards, and different requirements*. It's not clear yet, if the issues can be resolved, or when they can be resolved. MikroTik is still working on this issue.

If this problem is unsolvable (difficult to solve) you should have reported that all AC devices (ARM) do not support NV2. We would not buy them and did not solve it.
You solve this problem from 2017 and no result !!

why mikrotik still buy arm if mikrotik know problem?

Modern protocols are adequate and work really well without Nv2.
Nv2 is only needed if you have large legacy networks and need to add more devices to them.

The simple answer is that Nv2 is an old solution to an old problem, but modern CPUs are not compatible with it and don't really need it. We keep improving Nv2 for ARM, but there is only so much that can be done realistically. New versions are already better than it was.

We need to make Nv3 or something else, because software fixes will not be 100% enough. We keep improving Nv2 for ARM, but there is only so much that can be done realistically.

Hi normis,

we all know about this, but why Mikrotik is stop selling SXTac Lite5, this device works in old networks.
We have much places where we are not able to deliver proper Service with 802.11 (Data + Voip)
we need a TDMA based System.

Will we see NV3?

There are many reasons why older models can't be made anymore, and why new models have other types of chips, I can't go into that detail.

When works fine 802.11 with ap mipsbe and cpe arm?

There are other ways to resolve this, but they need new hardware.

For now you can use any outdoor devices with 802.11n (non AC), they are MIPS, for example LHG, LDF, SXT Lite series, SXTsq Lite series, Disc, Groove, Omnitik etc.

May be you could give some hope by talking on 802.11ax. As there are chipsets available I guess there is something in your labs.

We need solutions fast not hope & future promes.

Hehe, that took some time (a year?) to finally get a clear say about this.

Even with all my previous posts and tests last year showing NV2 was outperformed by plain 802.11 (and nstreme) if properly configured still this words where never used....

Suggestion: Write a comment in the wireless wiki that in heavy congested, dense populated P2MP network it is best to use 802.11?
(And by the way, I don't see so much difference between misbe or arm units. Even the DiscLite 5Ghz ac unit delivers my 30Mbps package date to the client.)
Just done some test with an 7 client P2MP AP that has overlapping 40Mhz channel with other AP and could push an LHG-5ac together with a DISC-5ac to both some 40-45Mbps, each on its own easy to 100Mbps.
Done the same test with 80Mhz channel (overlapping 3 other AP's) and could both have running some 70-80 each or as a single user could get 180-190Mbps on both...
Total throughput over the AP (Netmetal with RF-elements horn) was some 130Mbps max in 40Mhz but touching 200Mbps on 80Mhz channel....
Networks are in full 'ac' mode. nstreme is almost the same. NV2 sucks... not even half the speeds..... no matter what config I try....

For now good enough for my 30 and 50Mb packages.

I have to admit some of my AP's won't do as good as this one. It's a complicate puzzle to get the best results and signals can only be -60/-65 at its worse. Aim is -50 and preferred is below that.....
(Where I used to have 70% SXT's in my network, most of these are replaced now either by DISC-ac or LHG-ac. 2 years ago -60 was good enough, -70 workable, -80 the limit.....

Please @Mikrotik we only need that arm works in one protocolo very well, only one...

Use csma + RTS/CTS and you're fine...

aerosmith9110 · Thu Jan 17, 2019 3:31 am

I think these could easily been avoided all by indicated in the spec sheet:

Model:
xxxxxxx
Transfer speed via wireless link ( ideal condition )
802 - 400mbps both directions TCP
nv2 -100mbps both directions TCP
nsextreme - 120mbps both directions TCP

something like that. Then the customers would have an informed decision basing on the information given and there will be no threads like this as it would simply be dismissed as " Slower speeds are due to the protocol overhead or it was already indicated in the spec sheets "

How can i use this with my equipment?

1)NV2 802.11N +NV2 @ 20Mhz 100 mbit/s from sector 20 clients.
2)Pure 802.11N +rts/cts @20Mhz 90-20 mbit/s sometimes UPLOAD rates are falling to 6Mbps latency spikes. Some clients lose 90% packet loss (sector 20 clients)

NV2 works great for 20Mhz channel it does not scale correctly for 40/60/80Mhz. For good TCP/IP one session speed need rly good SNR from AP side (collocation problem).
