Well, mine's are send back via my dealer to MT upon MT's own request: "probably hardware failure".

So I'll wait until I got something back and try again...

it works great even when signal is about 100db.
What is 100db?

Anyway, they work great without traffic. The more traffic you put on, the sooner they loose the link.
20Mb of traffic runs for about half an hour and than the link collaps.
50Mb takes about 5 mins to make it collapse.
Max. speed was about 100Mb aggregated (So 60/40, or 70/30 etc.) up to 125Mb aggregated takes sometimes less than a minute to make the link drop.
Sometimes a disable/enable was enough the bring the radio back online, sometimes a complete reboot was needed, and on some occasions that was not even enough, it needed a power cycle reboot.

I've done several tests with them and showed all results to MT and the last word of them was: Send them RMA because probably hardware failure...

So, the units are shipped back through my sales channel (so it will take some time before they reach MT) and I hope to get some better performing units back. I will tests these under exactly the same circumstances so I'll find out soon enough if it is really a hardware failure (which I doubt) or another kind of issue.

My suspicions go towards the chipset/software combination. The link I use is NV2 with encryption on a very clean frequency (out of band) and when it drops it is each time because of NV2 errors.
When the link is made in a crowded spectrum (so in the normal 2,4Ghz band) it even lasts shorter.

Maybe also the software. I got very strange reading of the signal at time. Although the link signals were normally in the -35 to -40 range (7km link!) the sometimes showed -15 or even -5!
And in reducing the power level I noticed a change in outpot of 20dBm when changing between 23 and 24dBm power output...
So 1dBm change in power output made the other end signal reading jump with 20 or more dBm's... not good.....

problem all metals - pure cooling system. there absolutly no radiators on the atheros chips.


They are extremaly hot (ithink more than 100*С) when bandwith goes to 20-40 mbits\s.

Thermal sensor in metal is stupid. even outdoor is 10*C , metal just power on - he shows 33-35*C wtf?
here 2 pics. 1 pic - metal, 2pic - bullet. did you see the difference? main chip on the bullet is with radiator.

mtik have 2 atheros chips and both without any cooling system.

WEll, I agree on the temp issue. Already noticed that both during a hot summer day in the sun (metal felt really warm-/hot in the hand) and running or in the middle of the cool night the temp always is around 35 degree celsius.....

And yes, heating of the chip would explain why this so cold "industry standard" device crashes when it really has to perform (= traffic load)

My units are back for RMA on request of MT. "Hardware issue" was their argument. Lets see what they come back with.....

I have many Metal 2Shpn installed on different spots and the problem appears on some of them. Do you think that some heat conductive gel/foam placed between the case and the chipset would solve the problem?

I've found this from Fisher Electronik:
http://www.fischerelektronik.de/web_fis ... ndex.xhtml

It's a 5mm heat conducting compressible gel designed to be placed between electronics and heatsink. Considering the Metal's case as the heatsink i think it could resolve the problem. There's also from the same manufacturer a 6.35mm foam but it seems it has a lower thermal conductivity.

3M has something similar. If I can find where to get some I'll post the results.

The other side of the board is connected to the Metallic enclosure, which works as a giant heatsink. CPU doesn't need a heatsink, since it doesn't get very hot, and since the case works as a heatsink from the other side of the PCB. The issues you are seeing are probably related to something else.

Then you should tell us where's the problem because I've got an stock of about 20 Metal that are stuck there waiting for a solution. I've installed about 60 of them this summer and I've found the error in about 20%. We are replacing them for Grooves as soon as they stop working. Sometimes the problem can be minimized with an scheduled reboot every few hours but is just a temporal fix. We are not installing them by now waiting for a proper solution. If at least they failed from the begining we could RMA them before installing but the problem doesn't appear until they are on a production enviroment.

Please contact support@mikrotik.com and include the Serial Numbers from the Metal2 boards that have failed so we could check.

Great!
I have the same problem. I was changed my metal 2 to a new one yesterday, but the problem is the same. After about few hours the clients are disconnected until i reboot the metal.

It's amazing, all metal and I will send you back to sue for damages.

1 weeks before I realized that was just standing against a MikroTik problem again, you do not have a solution.

DO SOMETHING!!!!!!!!!!!!!

2 weeks ago I DID THE MISTAKE TO BUY 4 Metals...

"Mikrotik Support", who is gonna give my money and wasted time back...
I decided to remove 4 Bullet M2 connected to 13db omni antenna and working as an AP for clients in out hotel and because I was* a fan of Mikrotik and I needed do create a second "virtual" wireless interface for my purpose....
I did what, I found Metal as a competitive model to Bullet M2, even with better resources.... so I paid the money.... 1 week of problems and I put the metals back in the box and returned the bullets to the antennas.....
The problem: When we have 5 clients connected at 6 a.m in the morning we dont have problem, after 7 a.m till 12 p.m (when we have more than 10 clients connected) we have pings going to 1000 ms and more, ccq goes down to 5-10% and INTERNET??? No Internet.
in the other hotel, we have a RB433AH bought 2008 with 2 Mikrotik cards and 2 sector antennas.... 2008!!! and still working very well

What do we have here, RB Metals bought 2 weeks ago working as a shit !!!
Now my company has wasted money and even more, we have make our clients not happy with is, because mikrotik is afraid to say
DO NOT BUY RB METAL, cause we have an issue!!!! Because we are a small company and we are not able to test out product before selling it.... Is this your problem???

Iam not happy with you...
this topic has been started 2 years ago.... and u have no idea what is going on.... and haven't mention officially about the problem....
I want my money back or your product changed for a working ONE... What should I do ?

Hello Support.

I am an old hand radio guy. I have done radio for more than 50 years. When I first looked at the 2SHPn I thought it would have a cooling problem. I should be able to help you do some design modifications to help keep the internal devices cooler. Yes, I am sure this thing would melt in the sun in the Sahara. Outdoor enclosures are not simple. You need a sun shield and fins. A higher cost high temperature environment model might be a good idea.

I have had the radio shut down. I came here trying to find the data sheet on the radio chip you use. I have not found it yet. I am pretty sure the signal did not shut down last night due to heat, as it was cold here, and max traffic speed should not greatly exceed 8 mb/s out. I think there is another problem. Could it be SWR fault shut off coupled to a not very good antenna? That could be answered in the data sheet. In any event, when you get to 30 dBm you SHOULD have a directional coupler on the circuit card with a read out of reverse and forward AVERAGE RF power. That is another thing I might be able to help you with....

Still.... I think the problem may well be in your OS, as when this happens to me, I cannot generate an SUPOUT file. It jams. So.. that is a clue. I run it as a local HS with up to 5 uesrs. Last night it jamed up and off the air with no more than 3 users. It was cold out (approx 0 degree C). My next experiment is to move Hot Spot control into a different RB.

For the purposes of this forum.... the problem of reliability of this unit. continues.

This is a problem that goes back to the OS installed when purchased, a version 5.x.

Hi there,
Unfortunately, I am one more of the many affected, I have about 40 Metal installed in different locations, some work, some do not, and if they work, sometimes fail, not like the others, but once a month, for sure.
The problem specifically is that for no apparent reason, they are disconnected from other Metal (WDS) when these are linked.
Sometimes when the connection is cable, continue responding to ping, but not distributed, the WiFi signal to customers.
an
I've tried everything, Schedule reboot, every 3 hours, replacement of parts, such as power supply, or poe, RJ245 cable, antenna ... etc..
I have also purchased voltage regulators, on suspicion of peaks in the electrical network.
But nothing works; temperature is certainly an important factor, as this equipment, which are installed on the outside, but really do not have clear, that this, is the determining factor in the malfunction.
Right now I have an open Metal, and indeed does not have a heat sink on the (Atheros) CPU, will try to make one up and try.

If anyone finds a solution, share it, please.

Thanks

Sorry to say, you can only use them as CPE units. Replace with 433 and radios, the only real way of a solution.

Hummm... Power back off to maximum 30 dBm max did not cure this problem. Today, I had 4 outages. This is greatly more often than before. As of today I added to the set up a PPoE server... so the OS has even more to do. That may explain all the outages. Just before a reboot it did make a SPROUT file today, which it often has not, and maybe Tic support can look at it and find out what is happening. As of now, I suspect the OS is sending some wrong signal up to the chip. Only my guess.

I am thinking Mikrotik farmed out the design of the metal to a third party, and no one there knows enough about how it is supposed to work. I was told they do not have a data sheet on the radio. Without proper documentation one cannot design the unit.

Hi. Mikrotik support has asked me to update the OS and have done so from the unit as shipped, and then for for 6.15 and .16 and .17....yesterday I installed new firmware. No,it did not help, it shut itself off again near midnight local time.

It is interesting that it receives but does not transmit when it has failed. 802.11x is a time division duplex system, meaning the transmitter must shut off and on thousands of times per second. I have scanned the spectrum with another 'Tik while the Metal is in failure mode, and when I scan I see there is no signal on the channel or nearby channels. This was done using a Groove sitting nearby inside this home. If I can trust Mikrotik on its spectrum analysis, it means there is no interference, no malformed signal, no nothing on or near the frequency. Yet while not working the radio can recieve the weak cell phone wifi signal from a neighbour. This leads me to suspect Qualcomm as the point of failure. It is consistent with a transmitter turning off as instructed but not turning back on when instructed. I just wrote support@mikrotik that I will no longer work for them trying to debug this.. for free. The metal is in use, outside on a short stick, and in use by myself and 3 neighbors, and I really want to link up someone who cannot get internet who is dying of cancer. So I have a real DEADline.

I want them to just send me a replacement unit at their expense.

By the way, Qualcomm will not send me a data sheet for the radio chip... forget it. They do not answer email to a mere user.

I just noticed they just posted a 6.18 os... maybe I will upload it and try as I can do this from here with the cat on my lap..... but really, if it is a chip failure then what good is a firmware or OS change? I would be more impressed if sent a software tool that can debug the radio chip. :(
***************
Status 24-July-2014 20h28 UTC+2: : Kristaps at support said, "Please, download and install the latest pre-release nightly build:"
I did, I rebooted, it was installed as when I logged it said it was a release candidate, etc.. and tried to register to the Metal wifi. After 3 attempts I knew this release candidate is faulty. I saw the beacon and the signal was strong. But I could not register. So back to 6.17 for now. Phew. I wrote an email to the neighbors with whom I share wi-fi... trying to explain the almost 1/2 hour off air. Enough.
***************
Just noticed upon reboot it did not install 6.17 but is running v6.18rc4 and working thus far.. at 22h42. Two reboots ?
***************
v6.18rc4 still running since ~ 9 pm yesterday with PPPoE and other crash causing services. Much better than before. I will run a stress test later today.

I am flagging this Maybe Mikrotik has fixed it in the RouterOS v6.18rc4 built yesterday at 13h58, on top of firmware 3.17. It has been running almost 22 hours, PPPoE and Hotspot with attached users with no problems. I ran a bandwidth at test to my Groove for about an hour @ 162/145 mb/s, with no problems. Before now, this sort of stress would make the unit quit after only a few hours if not minutes. If after a week if it does not quit, I will believe it is now reliable.

My main complaint is that their tech people did not communicate with us. It is as if they fear admiting any of their products can be imperfect.

It looks like they have fixed problem where the wireless goes to 50% and stops responding but there is another problem. I noticed that the wireless will stay up and the registration will show the 2nd device connected but you can't ping the 2nd device. You have to stop the wireless and start it again on the 1st device. Once you do that it will start working again for awhile but it will eventual break again. I can reproduce this by doing a bandwidth test and setting the direction to both. After some time it will break.

My Metal has 4 or more registered devices all last night including this Dell laptop. When the AP is busy I have 4 mobile phones, my Ipad and test ancient Laptop, this Laptop, and two neighbour mobile phones registered via Hotspot. In addition I have the new Groove which I am trying set up to be CPE which connects to a secn VAP and then feeds using a different inexpensive little internal user friendly WIFI access point-router-PPPoE client... all this and the Metal is still going strong at Uptime 3d 11 h with lots of changes as I try to learn how to get PPPoE to pass traffic in spite of being pretty new at this MikroTik stuff. (Hot Spot + PPPoE + two internet connections maybe is complicating? The customer gets DNS but not anything else... yet... anyone want to help?)...

I would not yet trust that newer versions of routerOS are OK until we have been told they actually found and fixed their issue.

WoZeR, I could post the version I have, RouterOS v6.18rc4 built at 13h58, to a private FTP site if you did not happen to grab it and they happened to have changed it.

Thanks Lansman but that's the current version I'm testing right this moment (routeros-mipsbe-6.18rc4.npk).

It's looking better, the device is now usable but there are some stability issues to work out. I do agree with you about waiting for Mikrotik to release an announcement that it is fixed but they do need us to test every possible scenario and let them know if it works or not here. The only thing I'm worry about if they are actually reading our post. I'm upset about the very poor support I'm receiving. For some reason Mikrotik thinks it's best to keep their customers in the dark and ignore their support tickets. At least someone there is attempting to fix this issue.

Hello WoZeR and others. It Works!

The Metal has now been up more than 7 days without failure. The very marginal 1.1 km very not line of sight link goes from my barn to my friends home .. a friend who has late stage cancer, little mobile phone coverage... so I wanted to deliver some sort of connectivity... that link has been up a total of two days with no failure. The link is a poor signal with a lot of multipath as it scatters in trees and is blocked by two buildings. I would not call it professional. But it works well enough. The signal level is less than expected. I assume that is due to OFDM seeing multipath as a contributor. A high gain antenna, such as that used at the home sees less mutipath, thus less signal.

The other end is a Groove reporting ~ -80 to -83 dBm, the Metal reports -89 to -85. Omni on the Metal at ~ 8 dBi, 24 dBi connected to the Groove. The Groove goes to a TP-Link which dials into the Metal using PPPoE and then, being inside the home, delivers a nice wi-fi signal to the user. As other users of my Metal use cell phones, a lot of the barn received signal is very low. One is usually at -90 to -89 dBm, and is often deregistered and reregistered. So the Metal has a lot of work to do.

Now that it has been up a week, I declare it to be GOOD!

Hi WoZer. You said, "they do need us to test every possible scenario and let them know if it works...". True. But once we identify a repeatable problem, we should offer or support should ask for a copy of our backup files so that they can test to see if it is repeatable, and if it is to let us know, then they can find a resolution in house and post their progress in the research. I did offer MikroTik support my back up file. Had they taken it and tested using it, I would not have spent 100 hours trying to solve this problem, and other users would not have had the problems mentioned in this forum thread. Support has the spare equipment to run s similar set up. Then determine what should be done.

They are at fault for not asking for our back up files and replicating the probem in house.

(I am happy they did fix it though)

Re: Metal 2 shpn Problem in WIFI

We recently purchased 10 Mikrotik Metal 2SHPn routers and are having many problems with every unit. I am attaching supout files for both radios. As you will see, both units have firmware version 6.17. The basic configuration of each radio is as follows:

Radio #1:
- Mode: Bridge (with ether1 and wlan1 added as ports)
- Wireless Mode: AP Bridge
- WDS Mode: Dynamic
- WDS Default Bridge: bridge1
- Band: 2GHz Only N
- Channel Width: 20/40MHz HT-Above
- Nstreme Enabled with Framer Policy set to Best Fit and Framer Limit set to default value
- Distance set to “Indoors” since actual link distance is only around 20 feet

Radio #2:
- Mode: Bridge (with ether1 and wlan1 added as ports)
- Wireless Mode: Station WDS
- Band: 2GHz Only N
- Channel Width: 20/40MHz HT-Above
- Nstreme Enabled
- Distance set to “Indoors” since actual link distance is only around 20 feet

It should be noted that the testing described below is done in a closed loop test setup in that antennas are NOT used. The two radios are connected together using 25 feet of coaxial cable plus a 90dB coaxial attenuator to reduce signal level down to desired level. This setup ensures no wireless interference from other transmitters and virtually perfect CCQ. This setup I mention has been used for more than 10 years to test many different wireless routers that we have sold including many built with Mikrotik router boards and radio cards. This setup has worked flawlessly so please do not question the integrity or validity of this setup. Also, to verify this setup is still functional, we have tried using other wireless routers we have built using the Mikrotik router boards and radio cards (versus the Metal 2SHPn) and the problem described below does not exist. In that scenario, the only thing we are swapping out if the physical wireless radios themselves. All other test fixture components including POE’s, POE cables, coaxial cables, attenuators are all unchanged. Finally, I should also say that we have not seen this problem at all on the Mikrotik Metal 5SHPn only the 2SHPn. However the problem appears to be on every unit we test. The problem also appears to be aggravated when using Nstreme. I don’t understand this because again, we do not see this problem when using say RB433AH router board with R52Hn radio card.

I also want to say that I have reloaded flash with firmware version 6.17 using Netinstall so everything is reset to factory default from the get go.

The physical test setup, from one end to the other is as follows:

“Windows XP PC -> Ethernet Cable -> POE -> Metal 2SHPn -> 90dB Attenuator -> 25 Foot Coaxial Cable -> Metal 2SHPn -> POE -> Ethernet Cable -> Windows XP PC”

When I mention below passing data across the link, this is done using “iperf” on both PC’s, which is completely independent of the network devices between the two PC’s.

The problem we are having is this:
1) Wireless link is established very easily and will stay up for indefinitely until I start passing data across the link.
2) Once I start passing data across the link, the link will drop out completely within 2 minutes and sometimes never come back up until I reboot. Other times, the link stops passing data and the Wireless Registration table shows link is still up but last activity continues to increase indefinitely.
3) While the link is running data, the Tx and Rx Signal Levels are -57/-57 and Tx/Rx CCQ is 96/100.

Disabling nstreme eliminates this problem. I have just sent email to support@mikrotik.com. Given how long this problem has existed, based on this thread, I would certainly hope by now that Mikrotik knows about this problem and either has a fix or admits theirs and issue.

--- UPDATE ----
I just downloaded and installed 6.18 on both radios and ran the test again. Seems more stable but still have drop outs and occasionally the link freezes and never comes back up until units are rebooted as reported by others in this forum also.

There is a test 3.17.2-pcie-Metal-2SHPn firmware for these devices, but I don't know if it is included in the latest v6.18 package.
I got it from support for testing purposes. I haven't done stress tests, but I am using that firmware on some devices and I have 16 days uptime without problems.

Just another quick update. I sent a long email to Mikrotik technical support regarding the problems I was seeing and they sent me back an email with a link to a firmware patch (ar7240_3_17_2_Metal_2SHPn.fwf) specifically for the 2SHPn as the previous post mentioned. Per their instructions, I have applied this patch to all of my radios and also did a reset on the wireless interface of each radio. I have two identical test setup both running this patch and links are very stable now. I did have a couple of short wireless disconnects on one of my two test setups in the beginning but none for several hours now. Keep your fingers crossed that this problem, after a year and a half according to this thread, is now finally fixed!

Hi im new here (sorry my bad english).

I have a metal 2shpn too and i got the same problem but i can middle fix it with this config:

- Cpu speed at 250mhz (System>Routerboard>Settings apply the cpu speed and reboot)
- Distance: dynamic
- Wireless band: 2.4ghz only B ( i got really bad connection with G and N )
- Manual txpower at 32dBm
- Country: no_country_set
- Antenna gain: 15dBi (tp link 2415d)

It really stable but got high pings like 500ms, 700ms, 350ms, but clients can surf on internet no suffer disconnection im 9km away from metal. Hope this help someone while Mikrotik team fix this problem.

P.D: @MSSFL, @CyberTod can you guys put the firmware link i wanna test it, or @normis put link here for everyone please

Write me an email : (my username) at vestel.bg and i will send it to you.

Your high ping could be due to using only 'b' rates. If usage is high 11mbit/s wireless rates is just slow and will be filled.

It would greatly help if MT makes this file ar7240_3_17_2_Metal_2SHPn.fwf available somewhere for download if it really is the solution to years long problem with Metal2SHPn. There should also be an explanation or link on how to upgrade it, etc. I also have the same problem with Metal2 and hope this will fix it.

Good night,

I present this problem for a year and had to restart the Metal when he stopped sending signal to customers, sometimes up to 3 times per day, this had me crazy. One day I miss definitely send it off and lit forcing with cable, and nothing (Prior to that he had already changed the POE for Ubiquiti 24v, in case there was trouble voltage as the cable is Ubiquiti 40 Meters long and neither was the solution) after that night stop sending him under the antenna and spend all day trying it to catch from 7 AM to 2 PM, until the Netinstall Install the OS program from 0 by pressing the reset button for 15 seconds erase all data on it :( update the firmware to 3.19 reconfigure it got all customers EUREKA and the problem was solved, no thing happened the OFF SIGNAL now come to a conclusion: Mikrotik Metal you can not update, now I explain why 01 OS RouterBOARS saves the previous dirty data and creates a conflict for subsequent updates 02 OS is highly generic for all RouterBOARS consequently resulting in poor data management hardware or device drivers in this case Mikrotik Metal 03 garbage or temporary stays in the same partition occupying living space of the equipment operation and 04 a clean installation improves the use of RAM and CPU that makes the Mikrotik Metal stop working effectively causing it not fluent in terms of data delivery, I have made this device is more efficient than any Ubiquiti with resource consumption lower himself and very fast client-server performance this makes customers feel more satisfied than before, is more compatible with multiple receiving devices before offering a better service, now the same to have a ping failure it gives a very efficient without programming anything additional automatic restart, much lower temperature, the use low CPU and RAM too low, I am currently using version 5.25 and 3.19 Firmware without fail for almost a month solved the problem with a very high customer-company guarantee satisfaction ago.

i have upgraded to v 6.22 also firmware in my Metal 2Shpn. After up gradation, last few days i have changes all possible parameters but problem has not solved.

Smartphones, Wifi Usb Dongles & Ip cameras are connected and works within 20 Meters distance. Above 20 meters these devices are connected but there is no data transfer possible also getting packet loss.

Below is my Routerboard & wireless interface details :

Thought i buyed something good, but never have worked with a crappy device like this..

lot of hassling around to get it work, and after a wile stops working, it blocks and have to go up in the tower to get it out and to load new firmware on the pc.

Very unhandy software to make a quick setup, many things don t work properly ...

Send it back today and stay to ubiquiti bullets.


Cant make it better than it is, losiento

I don't have access to my Metal-2SHPn to configure it. I have used Eth1 Mac and Wlan Mac address but non change. I have trying to reset with buton. No change.
There are others solutions ?

Is this still an issue with the 2.4GHz MikroTik metal?

If it's still an issue, any similar model that has no problems?
I really don't want to use something else than RouterOS.
