ivaring · Thu Feb 08, 2007 5:53 pm

Hi all.
I tried this functionallity and it works really well.
Is this then active by default?, I mean, every log is sent to memory after any event (that I choose).

Thanks.

gregdhayes · Thu Mar 29, 2007 11:17 pm

I'm getting the MIC Failures on several of my clients. Interference isn't an issue on one of them and their signal is -50, ccq is around 99.

Client is conecting to a RB112/CM9 using a laptop. Two other customers are using Tranzeo CPE 90's.

They connect fine....then out of the blue I see those MIC failures.

Is there another explanation for the cause of these? Or is it just a compatibility issue between the cpe's and ap and using TKIP.

Thanks

R1CH · Fri Mar 30, 2007 12:44 pm

Advice for "no beacons" if connecting to a Cisco AP, you need to increase the beacon rate on the Cisco radio config. Default is 100 and all my routerOS clients constantly dropped with this error, changing to 50 and it's rock solid.

Talking about disconnection.

I suffered mainly two problems.
a) trees disturbing registration, so, moving antennas was the solution
b) excesive power on antennas, so, N/S ratio was too poor

I solved this problem, today not disconnection messages since 3 months ago!

Thanks.

你好,
I see a message not listed in your page:
"removed dynamic WDS link , name"
but don't know the reason of removal.

So many thanks for your very usefull page!

webformix · Sun Apr 20, 2008 5:53 am

Hey Normis, myself and possibly a growing number of other ROS users are experiencing issues that are detailed in my post @Client Disconnect Issues

This seems to be a ROS + XR2/SR2 + Tranzeo CPQ compatibility issue? I took a look at the list of disconnect messages that you've listed, and was wondering if you could shed any additional light on the following error messages:

exchange timeout or received deauth:
4-way handshake timeout (15) error.
group key exchange timeout
unicast key exchange timeout

Thanks in advance!

alex_rhys-hurn · Fri Apr 25, 2008 12:49 am

webformix,

I have just spent a happy day dealing with exactly the errors you list.

We solved permanently by changing channels. We were getting interference from a nearby wifi base station.

We found this with was happening with both Dlink DWL2100 AP in ap client mode and Mikrotik with R52 wifi cards.

Backing off the hardware retries to 4 from 15 made no difference. Playing antennae made no difference.

In the process we even found one client with many tx errors. swapped the client to no avail.

Changed channel and all solved.....

Good luck.

-headstrong- · 你e Jul 15, 2008 7:48 pm

I was also experiencing the problem of my wireless clients getting disconnected the whole time......

I had a few of them in "client bridge" mode and the rest in "client" mode...( my CPE's are all linksys but my AP's are all mikrotik)

So I put them all in "client" mode and magically all my disconnecting errors have dissapeared......So i'm assuming that wireless bridges cannot co-exist with wireless clients......not sure if this is correct but it works in my setup

EDIT: It has been 6 hours since i tried the above and not 1 disconnect...previously it was every 2 minutes

nilesh · Thu Jul 24, 2008 2:36 pm

is there any specific log messege to kmow the reason of disconeection like network conjstion or authenticaion failure.

is there any facility to know the percentage of collision in between 2 points

Thu Jul 24, 2008 2:40 pm

did you read the page in the original post ???

nilesh · Thu Jul 24, 2008 2:44 pm

i had read but there is nothing abt collision.

Thu Jul 24, 2008 2:49 pm

yes, there is nothing about collision, but there is certainly a lot about disconnection messages when authentication failed.

there is no way to determine any collisions.

I could not debug but I tried to use C9 in ap bridge mode and clients get disconnected very often. How can I use it as AP and not have problems do clients "see" if it set to "client" mode?

How about "disconnected - too many poll timeouts"

jcremin · Thu Jul 23, 2009 5:07 am

How about "disconnected - too many poll timeouts"

I'm getting this a lot too with the newer wireless-test package with nstreme and polling enabled. One one specific tower, everything is fine if the noise floor is -99 or -100, but if it gets any worse than -98, everything starts freaking out and the only way to ensure a solid connection is with a -60 or better signal. It should be much more stable at much lower signals than that.

what is your HW. retries value? If you have a newer ROS the default value is 4. It may be too low for the good link. I have just solved disconnect problems on nstreme link (no dual nstreme) with changing Hw. retries from 4 to 10 (ROS 3.30). The link was working fine except that it tended to disconnect frequently under load. After the change links never disconnected yet.

Did you change the HW retries to 10 on the AP or the AP and CPE?

I changed hw. retries on both sides. But it was a PtP link - not AP with many clients.

Perhaps it would be enough to increase the retries on only one side ( the side which as problems with delivering frames to the other side) - if a problem affect only one direction

ibeeby · Thu May 13, 2010 9:15 am

Very helpful and well written article - exceptionally useful for those with wireless issues to resolve.

A link to this article should be made sticky in the Forum imho as I suspect that it will answer a lot of faqs immediately.

Thanks Normis!

what is N/S ratio mean?

cmit · Thu Jun 10, 2010 9:59 am

I think S/N raiot was meant, meaning signal/noise. So how much "louder" your signal is than the RF noise that's around. If your signal is too weak and nearly at the level of the noise, the receiver on the wireless card cannot detect and decode the signal correctly.

is there any algorythm to solve such behaviour of the wireless interfaces. once i set "dynamic size" to give best performance, another time - "best fit"... what is the secret actually?

andycelo · Wed Apr 04, 2012 2:58 pm

Hello,

i have problem with disconnecting - too many poll timeout message. Connection is very unstable, max uptime 5day, signal -54dBm, signal to noise 64dB, CCQ 100/100%. On AP side 435g with 3mini PCI R52nM card, other sides clients two 433ah and alix with the same type of cards. Problem is only in card which is AP bridge 5Ghz N with Nstreme. (The rest two card in 435g are 5Ghz-A with nstreme in AP mode, there are no problems.) Traffic in n mode with bandwidth test aprx 105mbps rx and tx. I try change routerboard 435g two times, all the card maybe three times. Tested version 4.17, 5.9, 5.14 on both sides, with very similar result. By the version 5.14 disconnect all three clients in the same time, version 4.17 usually disconnect only one client. HW retries try to set from 7 to 15 on both sides many times, the result was max 5day uptime, anyway try to change TX power signal. Nstreme settings: enable-nstreme=yes enable-polling=yes disable-csma=no framer-policy=best-fit framer-limit=3200. Connectors, cables and antenas checked. Connections from the same place to other side in 5ghz-turbo mode aprx 350days uptime, without any disconnects.

Pls, any other ideas how to solve this problem???

Andy

sonny · Sat Apr 14, 2012 11:42 am

andycelo:

Try to use another channel. Your noise is to hi -64? normaly this should be the signal strength.
Noise should not be mor then -88 to -90. Better -100

Use RF shields for your antenna.

I'll guess progress is slow.... Its 2012 now and NV2 already in use for some years but still no update on this document in regard of message produced in NV2 networks.....

Also, the link at the bottom to a doc. fm GTHill.com is not working any longer...

icedblind · Fri Jun 22, 2012 11:36 am

你好,

we have a ptp link, each one built with:
- RB 411AH in plastic enclosure
- rOS firmware 5.17
- radio card Ubiquiti sr71-15
- dual pol dish antenna with 29dbi gain
configuration:
- nv2 enabled with security
- chains enabled: 0 & 1
- current Tx power: 9db
- tx power mode: card rates
link data:
- 18km link
- los/fresnel respected
- rssi -66/-66 dBm
- snr 53 dB
- noise -120dbm
- ccq 98/100%

Both points have - frequently right now - disconnections, for this reason in log:
"wireless,infomac@wlan1:lost connection, not responding"

We've already changed both routerboards and radio cards, changed frequencies, changed position of antennas, downgraded and reupgraded fw, changed tx power, switched to 802.11.
Nothing says that there are interferences on air (happens on every free frequency), disconnections appear accidentally at any time, night or day.

How is it possibile to dig deeper on this log message & find a solution?
(in logging, "wireless,debug" enabled in memory, see attached image)

Thank you.

Dear Sir

I had configured one point to point link getting RSSI 64/68 but in that the link bandwidth throughfut is only 3mbps , where the hardware is RB433AH, with 800mW card, some times working well but some times it is not working well,

Can you please let me know how to improve the signal !!

Thanks in advance

Hello Normis,

I am getting severe wireless link discontinuity issue in my PtP link. I'm receiving following error in my mikrotik logs :-

lost connection, received deauth: class 2 frame received (6)

What is the issue in the link? What i have to change and where? How to fix this?

Any help will be appreciated and will be a very grateful to fix this issue. Thanks.

Fri Apr 15, 2016 7:49 am

Other side receives the packets sporadically, may happen it considers the link to be lost and then it receives another packet. As the connection from its point of view is not established anymore it responds with deauth. Your signal strength/quality is obviously too low.

Hello Jarda, how's you. i hope its going good there and thanks for your post reply.

Actually, i am facing Mikrotik PtP wireless link discontinue issue over 2.5km distance. At AP site there is RB433AH with EnGenius radio card connected 15dBi antenna and at station end there is Groove 52HPn with 29dBi grid antenna. Also, client registration at AP end goes to disappear and then tries to get reconnected and comes again, CCQ also goes to down 15-18%. It keeps continue happening. I have been checking at both the ends at AP site changing R433AH with new one and new radio card and at station end with new Groove 52HPn. But link discontinue problem still persist. There is one thing at AP site with RB433AH i had first old version ROS 3.10, as it was very old card and working rock solid without any issue, but after upgrading the ROS version to 6.34 problem gets started. Also, there is other XR5 card attached to this board linked at 7km to an another Groove 52HPn station, but no issue at all even signal strength is low still working good.

Sun Apr 17, 2016 10:08 pm

Hi.
嗯,你知道它是如何。有太多的联合国knowns, the debugging of long links is sometimes like forecasting from the crystal sphere. Bad signal level is the first. You should reach around -55db on both sides, with some 45db snr. Sometimes a connector could be bad, sometimes the wet could leak in the cable, sometimes a good neighbor is transmitting your way on close frequency. So, spectrum analysis on both sides is necessary too. Finally you may move to integrated all-in-one single purpose device like QRT or dynadish or even maybe the LHG. No hassle with cards, enclosures, pigtails, antennas... maybe just wind blown into your antenna and it moved a bit. You could check it and re-align. It looks it may be connected to the update, you have made. I have good experience with 6.32.3 (wireless-cm2), now maybe the 6.35 (wireless-rep) could be good too. It is too early to say, but you can try it.

See? you can try everything. None knows what will help in your case.

dalex · 你e Apr 19, 2016 2:06 pm

I had the same problem when i upgraded to 6.34.x some 911,s, an 411AH, and an 433AH (both with RB52HN).

Links that were 140 days rock steady, started disconnecting every 10 - 60 seconds. Terrible.

I thing it has to do with the "wireless" to "wireless-cm" transition that MT enforced.

Switched back to 6.32.3/"wireless" totally fixed the problem.

In some h/w use of the "wireless-fp" package fixed some of the problem. Thank you Mikrotik for the new LOW-ROM devices that made downgrade impossible !!!

esbenrug · Thu Oct 06, 2016 11:24 am

你好,

First, I would like to say that this page is really awsome. Thank you.

I am trying to establish a dynamic WDS connection but it fails. So I went to the page to get help and I think I found a typo:

@: connected [, is AP][, wants WDS]
Station with address connected. if "is AP" present - remote device is AP, if "is WDS" presents, remote device wants to establish WDS link.

Shouldn''t "is WDS" be "wants WDS" in the explanation or are those two different error messages. I get "wants WDS" but your explanation of "is WDS" suits "wants WDS" well I think. If they are two different error messages what is the explanation of "wants WDS" then ?

我不知道mikrotik implementation but I would say: NEVER USE TKIP. In the Standard is antihack feature and all clients get deauth'ed if that kicks in. (This is true for other manufactures following that standard and I would guess that Mikrotik is following the rfc's as well.

Same problem here out of box with new HEX3 and 3 WAP AC.
我做了最基本的可能configuration using HEX as CAPSMAN controller and 3 WAP AC and when i try to connect with any device i have here i get 4-way handshake timeout error, whats strange only one device manages to connect and thats old Asus laptop equipped with Intel 4965AGN.
I tried upgrading all devices to latest 6.39rc68 than reseting them to factory defaults and again done the most basic configuration again same error across several devices, only this Asus Intel 4965AGN connects and works fine.

Iv also sent supout to mikrotik support, hope this gets solved soon as i need to deploy this soon..

EDIT:I kinda got it working, for some reason it doesnt accept any letters for WPA and or /WPA2, if i enter any numbers it works like 1234567890, if i enter 123456789A it doesnt work, whats going on i dont understand this?

EDIT:Now again doesnt work no matter what combination of password i enter, this is driving me nuts..

extensive data loss, bad signal.

i am having same issue on the clear line of sight, where the client is not far than 500meters, so how can you say bad signal??

am currently having severe and frequent intermittent WIFI disconnections on my CRS125-24G-1S-2HnD-IN ... is there any idea/help what this might be caused with please?

Thu Jun 28, 2018 7:52 pm

Normis,
do you take care about the manual web page? Please, update!

The link to pdf on the bottom of the page does not work also.

I am also receiving "disconnected, received deauth: authentication not valid (2)" on AP side and "no beacons" on client side every few seconds while the link otherwise is able transfer data meanwhile.

edit: I switched on "keepalive frames" on AP, looks the messages stopped. At least for a while now...

edit2: it didn't help for long. Searching for real solution...

improvement in wireless logs are much appreciated

for example en latest versions y have noted log reports client signal level at connection event, very useful

thx

HI Normis

This will help us here at MIRO Distribution so much with technical support for clients on the wireless without sending the supout rif files up to MIkrotik when needed. Much appreciated.

For those of you that have disconnects, reconnects and reassociations especially ion iOS devices, and i think there are a lot of you since this is an old issue, try this:
My device is RB951G-2HnD and various iOS 13, 14 devices. Before bellow setting all of them were reassociating and generated the log entries which we all know by now.

1. Make sure you are not using an older version of ROS (not less than 6.44.6)
2. Increase key echange interval from 5min to 30min or more.
3. DHCP lease of min 2hours.
4. Band: 2GHz-G/N
5. Channel Width: 20MHz
6. Frequency: Avoid Ch 6 (as it is set by default on many routers) use Ch 1 (2412) or Ch 11 (2462)
and most important
7. Disable AMSDU (Wireless -> HT Tab) and only AMSDU. Leave AMPDU Priorities as is, with 0 checked.
To disable AMSDU enter 0 to AMSDU Limit and AMSDU Treshold.
Also, AMSDU does not work well with noisy wifi environments... (crowded apartment buildings)

YES, i know that disabling AMSDU will decrease your throughput but not as much as you might think.
With above settings I have a N Wifi network with a speed of 8...10MB/s throughput and no reassociations/reconnects.

I'm not saying this will work for everyone but maybe it will work for you as well.
It depends on your use case and needs (max throughput or max connection stability)

I set wireless, debug but I never see any wireless debug messages in the log. Lots of wireless, info messages though.
