From this thread:

My latest update from support:

new changed poe-controller firmware will be included into RouterOS 5.22. It will
address "crazy lights" when in auto-on mode, weirdness with ether5 port. However
it will not address issues with forced-on mode.

So, how serious is this? Every links goes down now and than. Should I now upgrade or not? (I just finished upgrading to 5.21...)

Did the links stall under certain conditions? Or in general.
In the first case I would like to know what these conditions/configs where.... In the second case I probably need to update again soon.... (after not too many issues are being reported here...)

Has anyone considered that having so many different torrent files means far less effective seeding? Someone who downloads the mipsle torrent, can only peer with someone else who downloaded the mipsle torrent--in particular, they cannot peer with somebody who downloaded the "all files" torrent. And vice-versa. For each of the platforms. Rather than all ROS torrent downloaders sharing files in one group, there are now five disjoint sub-groups. Bad Idea™!

It would surprise me if most BT clients did not have the ability to select a subset of files to download. It would be much better to leave that to the BT clients, and keep everyone using the same torrent file that includes everything.

PoE controller firmware somehow did not qualify as RouterOS change as they are separate entities within RouterBOARD

Posted: **Mon Nov 26, 2012 10:59 am**

Guys, what's up?

I have upgraded one RB750G (remotely).
On first reboot nothing happened.
After second reboot I've lost connectivity to the router, because ChangeIP script stopped working.

On closer examination I have found out that half of the /tool commands are missing (compared to 5.16), among others dns-update !!! That's why changeip script was not working.

Is this some kind of error during upgrade, or is it "by design"?

Posted: **Mon Nov 26, 2012 11:24 am**

check if package advanced-tools is properly installed as most of stuff in there comes from it.

Posted: **Mon Nov 26, 2012 12:03 pm**

Right on target - it's NOT installed !!!

How come? It never happened before.

I am not an expert, and have no experience with such problems - could someone please give me instructions how to check if advanced tools are present in NPK served for download, and how to install it separately?

Posted: **Mon Nov 26, 2012 12:05 pm**

security and advanced tools is missing ......

Posted: **Mon Nov 26, 2012 12:29 pm**

advanced-tools and security is part of the combined package. You can attempt to upload it again and reboot the router. Or, download all packages.zip and there are separate packages available.

Posted: **Mon Nov 26, 2012 12:47 pm**

Yes, I downloaded .ZIP package, extracted those two missing packages, uploaded them to RB750G and rebooted.

The question is:
* were those packages integrated in routeros-mipsbe-5.22.npk
* how could I check (peek into) NPK before reboot
* if packages were there, what went wrong the first time

It never EVER happened to me in 4 or 5 years of using and upgrading Mikrotik RBs - that's why I am a bit puzzled and certainly worried.

Posted: **Mon Nov 26, 2012 1:16 pm**

Suceeded ....

But I still wonder if those packages were inside .....

I'd like some additional information on this as well. I've noticed a problem where some NV2 configured access points would just stop sending/receiving data and would not start again until the interface was disabled and then re-enabled.

Does this fix that issue? Is there a detailed bug report we can see?

Posted: **Mon Nov 26, 2012 9:11 pm**

Glad to see the nv2 stalling bug reported as fixed, need to ask if it depends on only bridge/AP side, or also stations need upgrade?

For everyone that says there is no options in Advanced tab it was already discussed in another topic.
The options that are shown are the only relevant for the currently selected wireless mode. For example there is no ack setting in nstreme. That is why it is not shown in Advanced. Switch to a protocol that uses the option and you will see it.

It happens almost every time I try to log in throuh web-interface (Safari) on iPhone. What do you mean by asking "What happens if you manually open the IP address of the hotspot router- does it allow to login?"? In address bar of Safari I enter IP-address of my RB750G, on logon screen I enter password (user "admin" automatically filled in) and press logon - after a few seconds I see the same logon screen with message "Internal Server Error" below password field.
Will try to send supout.rif soon.

Beginning on Nov 12, several devices on our network are having their (static) DHCP addresses deassigned and immediately reassigned every few hours, intermittently, despite the standard 3-day lease length. Here is the log of the most recent incident (MAC addresses changed, obviously):

Nov 30 12:49:01 33Comm LAN-DHCP assigned 192.168.151.245 to bb:bb:bb:bb:bb:bb

At the same time that this occurs, current connections (e.g., VoIP, Skype) on these devices drop.

Relevant settings (export compact):

/ip pool
add name=LAN-pool ranges=192.168.150.100-192.168.151.249

/ip dhcp-server
add add-arp=yes address-pool=LAN-pool authoritative=yes disabled=no interface=\
    ether1-LAN name=LAN-DHCP

/ip dhcp-server network
add address=192.168.150.0/23 dns-server=192.168.150.1 gateway=192.168.150.1 \
    netmask=23 ntp-server=10.0.1.13

/ip dhcp-server lease
add address=192.168.151.244 client-id=1:c0:3f:e:10:21:7b mac-address=aa:aa:aa:aa:aa:aa server=LAN-DHCP
add address=192.168.151.245 client-id=1:0:e:8:d9:a9:11 mac-address=bb:bb:bb:bb:bb:bb server=LAN-DHCP
add address=192.168.151.246 client-id=1:0:e:8:d7:60:34 mac-address=cc:cc:cc:cc:cc:cc server=LAN-DHCP
add address=192.168.151.247 client-id=1:0:e:8:d8:4c:fb mac-address=dd:dd:dd:dd:dd:dd server=LAN-DHCP

Pretty straightforward, I think. I am not sure if this is caused by the dhcp-server system (e.g., changes made for 5.21) or something else; Hopefully, this will help someone track down the problem. If anyone has any insight into this, or this issue has been seen before, please let me know!

Since I am on the verge of losing a customer due to this behavior, I am going to try giving these devices static IPs (manually, not using dhcp-server) and see if that eliminates the drops. Since this will suggest whether the problem is within the dhcp-server system or elsewhere, I will follow up with my own results next week.

EDIT: This is on a RB750UP, currently running ROS 5.22. Upon further perusal of the logs, this deassign-reassign pattern goes back years--but this is the first time I have noticed it happening with static leases, and with devices for which it causes the user a real inconvenience.

Suddenly one by one our CPE:s stop working, no traffic on eth1 at all, DHCP offer we see only, nothing more.

I've installed NTP client before upgrade, but after upgraded the package was gone, and I tried to check the time thru logs, and it put the right time.

"System -> Resources" claim to have 4GiB free memory on my RB450G, while graphs say for example "Max: 345.17MiB (137.4%); Average: 124.61MiB (49.6%); Current: 66.73MiB (26.5%);". When I clean out the proxy cache stored in RAM all goes back to normal. I've 50% of RAM allocated for proxy cache.

So here's how it looks from terminal:

The scenario is Sextant AP ----> Sextant station bridge (protocol nv2) ... after 1 day trafic stoping. Enable disable wireless interface traffic comes. When ptotocol is nstream no problem. Downgrade to 5.18 NO problem too.

do you have 5.22 on both sides?
Please make support output file at the time when it is happening. Also if it is possible make support output file from the remote location.

Am I missing something in 5.22 but in Winbox, wireless settings, NV2 Tab a heap of settings missing, TDMA Period Cell radius etc only field there now is the security check box and entry..

Only accessible by terminal now ?

most likely you are configuring the Nv2 station end. For Nv2 station you only need to check if you willl use security or not as all the other Nv2 settings are sent and configured by AP.

There's an issue with 'export compact' feature

It does not include the SSID if the radio is in NV2 mode AP/bridge

This is from a 711GA-5HnD

Hello Folks!

PROBLEM!!

Suddenly one by one our CPE:s stop working, no traffic on eth1 at all, DHCP offer we see only, nothing more.

Known affected devices so far RB411

Rollback to 5.20 solved the problem.

we need support output file from that situation so we could understand what is causing that.

RB433AH

After few hours again "rebooted because of kernel failure" and CPU 100% and 100MHz !!!

ROS 5.22 looks like early beta...

please make a support output file from that router and send to support@mikrotik.com
What RouterOS version you were using before v5.22?

Posted: **Mon Dec 03, 2012 2:17 pm**

Day 4 of 5.22 testing = no problems.
3 RB800 AP's with R52Hn wireless cards
1 RB493 switch
10 RB711 CPE's

Waiting for more feedback before we roll-out 5.22 to hundreds of AP's and thousands of CPE's.

Segir, have you tried to install a Chrome on IOS device, does it work with it?
With RouterOS v5.20 you didn't have such problem?

Installed Chrome browser on iPhone - no problem with log in (tried several times - every time successfully). But with v5.19 and earlier versions - I have never met such problem with Safari browser on iOS.
As for v5.20 - didn't test this version (upgraded from v5.19 to v5.21, and later upgraded to v5.22 - on both 5.21 and 5.22 I met problem with "Internal Server Error" when trying to log in).
Yesterday I sent supout.rif to support@mikrotik.com (Ticket#2012120366000531)

When removing an UPS, or changing the serial port of an UPS, the previous serial port is still assigned to the UPS and unable to be reused by any other process.

what do you mean by "changing the port"? how many serial ports does your device have, and why are you changing them?

RB1100AH.
I had an issue with an UPS that doesnt want to be recognized after a reboot. I tried to assign the UPS to the second port, but the first serial port is still show in used by the UPS. Even after removing all UPS from the setup, I can't even use the terminal to serial as I get an error that the port is still assigned to the UPS even when there is no more UPS in the setup.

Do u still have this problem with 5.22 because I have this problem with previous version
but now 2-3 days with 5.22 seam fine

I confirm this problem still occur.

Hi... RB450G in bridge mode, ports 1 y 2 bridged, rstp, fw on, when traffic comes through the bridge, the rb reboot all the time... like in loop... I diconnect from the lan the port 1 and rb becomes stable... BUT with no traffic at all... same config with 5.21 and earlier firmwares works fine... I probe it in 3 diferentes segments of my lan, in 3 differents RB with the same results. I'm going back to 5.21 and problem solved. It is a BUG ?

what do you mean by "changing the port"? how many serial ports does your device have, and why are you changing them?

You can just make the following try:

add a UPS to serial0.
In port, you will see that serial0 is now used by UPS.
Delete the UPS.

Do a system serial-terminal serial0 and you will have the following error: failure: port's channel is already in use
If you go to port, you will see that serial0 is still used by UPS even if you don't have any UPS in the system.

My problem is that once a port has been used by a UPS, you can't reeuse that port for anything else until reboot.
I call that a bug.

HI
Occasionally, i have almost 90% cpu load on my RB1200 v 5.22 for the short period of time.
This is not related traffic, a number of connections, because everything stays constant.
Did anybody faced same issue?
I'm thinking about snmp issue , but Normis told that it was fixed several version ago.

http://forum.mikrotik.com/viewtopic.php ... management
THX.
P.S

Read in another post about someone who had a similar problem so i changed my dude settings on the specific device and unchecked the Router OS checkbox in the general tab in the dude. It seems to have solved the problem.

This helps me as well. So, it's dude or snmp issue?

Posted: **Tue Dec 18, 2012 7:18 pm**

Maybe you have the default ssid=MikroTik?

Definitely not. These are configured sites upgraded to 5.22 where we see this

Posted: **Thu Dec 20, 2012 7:17 pm**

Is there a valid link to a non torrent DL? Work doesn't let me use torrents and the 5.22 file in the downloads section is missing a bunch of things and the upgrade fails. I have 15 or so client that all got caught with the firmware upgrade bringing their devices down and now I'm going to have them ship em all back so I can fix them.

I confirmed the file is not working my side as well and have a now useless device sitting on my desk.

DOES NOT WORK unless repaired your side already.

Hi i have problem with KVM on x86
for bench testing I loaded 20 Ros KVM into a Dell Routeros Host

occasionally a kvm crash and get stuck and wont respond.

And more importantly i am able to crash the entire routeros host ( dell box )

if i start and stop the Traffic generator many times off and on in a short period

result the server does not recover and i must walk into the server room and manually reboot it.

p.s is there a know stable version of ROS kvm? I want to generate my lab with out these failures

Beginning on Nov 12, several devices on our network are having their (static) DHCP addresses deassigned and immediately reassigned every few hours, intermittently, despite the standard 3-day lease length... At the same time that this occurs, current connections (e.g., VoIP, Skype) on these devices drop... I am not sure if this is caused by the dhcp-server system (e.g., changes made for 5.21) or something else; Hopefully, this will help someone track down the problem. If anyone has any insight into this, or this issue has been seen before, please let me know!

EDIT: This is on a RB750UP, currently running ROS 5.22. Upon further perusal of the logs, this deassign-reassign pattern goes back years--but this is the first time I have noticed it happening with static leases, and with devices for which it causes the user a real inconvenience.

NO COMMENT on dhcp-server deassigning and reassigning leases at odd times?! This isn't happening to anyone else?

Since the last time I reported this issue, I have replaced the RB750UP with an RB2011UAS-2HnD and created an all-new configuration, but this problem still happens. VoIP calls are disconnecting, remotely-mounted file systems are disconnecting, it's a mess.

Just today, the log shows DHCP being deassigned and reassigned to the same device twice: first at 11:24am, and again at 4:04pm:

Jan  9 11:24:05 33Comm LAN2-DHCP deassigned 192.168.152.20 from [hh:hh:hh:hh:hh:hh]
Jan  9 11:24:06 33Comm LAN2-DHCP assigned 192.168.152.20 to [hh:hh:hh:hh:hh:hh]
...
Jan  9 16:04:14 33Comm LAN2-DHCP deassigned 192.168.152.20 from [hh:hh:hh:hh:hh:hh]
Jan  9 16:04:15 33Comm LAN2-DHCP assigned 192.168.152.20 to [hh:hh:hh:hh:hh:hh]

Config:
/ip pool
add name=LAN2-Pool ranges=192.168.152.10-192.168.152.250

/ip dhcp-server

At the very least, I would expect these events to occur three days apart; i.e., the duration of the lease. And I certainly would not expect a DHCP renewal to cause connections to drop. Insights, anyone?

This is probably normal behaviour. A DHCP client should renew its IP adress at half leasetime. Most clients do it more often in my expreience.

Renewing the lease might be normal behavior, but not dropping connections as a result! I found these deassign/reassign events because they coincide with the client reporting that an application's remote database connection closed unexpectedly. It has been happening several times a day. Not all of them trace back to one of these DHCP events, but the fact that two of them do makes me suspicious.

How would I go about confirming whether this is initiated by the client, rather than a bug in the dhcp server? What packet-sniffer settings will capture a DHCP release/renew from the client, and little else?

Posted: **Fri Jan 11, 2013 3:29 pm**

This cannot be normal dhcp-server behavior, nor can this many different clients (owned by various individuals working in different organizations) be misconfigured in the same way. This isn't even the complete list for one day, just the more egregious examples:

DHCP deassigns/reassigns the same IP to the same MAC three times within fifteen seconds:

Jan 10 10:12:48 33Comm Hotspot-DHCP deassigned 10.1.150.82 from [mac1]
Jan 10 10:12:48 33Comm Hotspot-DHCP assigned 10.1.150.82 to [mac1]
Jan 10 10:12:57 33Comm Hotspot-DHCP deassigned 10.1.150.82 from [mac1]
Jan 10 10:12:57 33Comm Hotspot-DHCP assigned 10.1.150.82 to [mac1]
Jan 10 10:13:01 33Comm Hotspot-DHCP deassigned 10.1.150.82 from [mac1]
Jan 10 10:13:02 33Comm Hotspot-DHCP assigned 10.1.150.82 to [mac1]

Assigned, then 7 minutes later (de)assigned 4 times over the course of ~6 minutes:

Jan 10 14:23:06 33Comm Hotspot-DHCP assigned 10.1.150.60 to [mac2]
Jan 10 14:30:38 33Comm Hotspot-DHCP deassigned 10.1.150.60 from [mac2]
Jan 10 14:30:38 33Comm Hotspot-DHCP assigned 10.1.150.60 to [mac2]

Jan 10 14:32:23 33Comm Hotspot-DHCP assigned 10.1.150.60 to [mac2]
Jan 10 14:33:15 33Comm Hotspot-DHCP deassigned 10.1.150.60 from [mac2]
Jan 10 14:33:15 33Comm Hotspot-DHCP assigned 10.1.150.60 to [mac2]
Jan 10 14:37:00 33Comm Hotspot-DHCP deassigned 10.1.150.60 from [mac2]
Jan 10 14:37:00 33Comm Hotspot-DHCP assigned 10.1.150.60 to [mac2]

(de)assigned only 30 seconds after the initial assignment:

Jan 10 16:29:32 33Comm Hotspot-DHCP assigned 10.1.150.86 to [mac3]
Jan 10 16:30:04 33Comm Hotspot-DHCP deassigned 10.1.150.86 from [mac3]
Jan 10 16:30:05 33Comm Hotspot-DHCP assigned 10.1.150.86 to [mac3]

...and then half an hour later, most disturbingly, the same device is deassigned, and then reassigned a different IP:

Jan 10 17:02:27 33Comm Hotspot-DHCP deassigned 10.1.150.86 from [mac3]
Jan 10 17:02:30 33Comm Hotspot-DHCP assigned 10.1.150.66 to [mac3]

When would that ever be desired behavior?!

Assigned and deassigned twice over the course of one second--and left deassigned?!

Jan 10 23:40:46 33Comm Hotspot-DHCP assigned 10.1.150.46 to [mac4]
Jan 10 23:40:46 33Comm Hotspot-DHCP deassigned 10.1.150.46 from [mac4]
Jan 10 23:40:46 33Comm Hotspot-DHCP assigned 10.1.150.46 to [mac4]
Jan 10 23:40:46 33Comm Hotspot-DHCP deassigned 10.1.150.46 from [mac4]

Interestingly, in this last case, the log file on the board itself shows this (de)assignment happening seven times in one second, and leaves it assigned. The above is taken from its remote log. On the board, the log file reads:

jan/10 23:40:46 dhcp,info Hotspot-DHCP assigned 10.1.150.46 to [mac4]
jan/10 23:40:46 dhcp,info Hotspot-DHCP deassigned 10.1.150.46 from [mac4]

Clearly something is broken!

(de)assigned only 30 seconds after the initial assignment:

...and then half an hour later, most disturbingly, the same device is deassigned, and then reassigned a different IP:

Jan 10 17:02:30 33Comm Hotspot-DHCP assigned 10.1.150.66 to [mac3]
When would that ever be desired behavior?!

Assigned and deassigned twice over the course of one second--and left deassigned?!

Clearly something is broken!

I have the same problem with many customers on 5.22 and DHCP leases, Yes there is something wrong with 5.22 DHCP

This cannot be normal dhcp-server behavior, nor can this many different clients (owned by various individuals working in different organizations) be misconfigured in the same way... Clearly something is broken!

I'm glad to know it isn't just me or something flaky about our configuration. Are you also experiencing the breaking of persistent connections (VoIP, RDP) when this happens? Do you suppose downgrading to 5.21 might improve the situation?

I have downgraded some CPE's to 5.20 because the logs on cpe's running that version did not have dhcp issues and i needed a quick if temporary fix for this, on the AP's and a lot of cpe's which are still 5.22 until i downgrade is to remove any IP Services not being used for me i use only Winbox + Telnet the rest API,ftp,ssh,www-ssh and especially www are not used so i disabled not sure it will help.

we are interested in your problem about DHCP-server leases reassignments.

1) Please run /tool sniffer on DHCP-server interface, during assignment/deassigment;
2) Make support output file after clicking stop on /tool sniffer;
3) Send both files for us, we will research where could be the problem (I assume local network works fine and there is no problem with wireless disconnects, bad switch, etc.).

@Sergis I have the same issue and will follow your instructions, in response to question about local network works fine and there is no problem with wireless disconnects, bad switch, etc.
Usually I check wireless registration and when it says uptime in days and customer says they have disconnects several times daily I had assumed it was being caused by some other device on the customers LAN and did find with one customer a rouge DHCP server which was taken down but then another customer asks are we having network issues and another then checking at random many customers CPE logs and DHCP leases reassignments - alarm bells rings? on checking customers with 5.20 they did not have these DHCP leases reassignments so i used DUDE to force upgrade to 5.20 ("force upgrade" which should be titled "force install"?) and I have disabled ports not used to access the routers and in my case i use only Telnet,winbox,
I will forward the support output file and /tool sniffer files to support

Below is just from one customer

I have this DHCP problem a lot of time and never can fix!

Many times the reassigned IP is different of the deassigned and the client figure like connected in the hotspot with the old IP and not allowed more sessions to the client and we need to remove the client manually to allow reconnect again!

In the last v6.0 of May 17th the problem persist...

Any help?

RB1100AH.
I had an issue with an UPS that doesnt want to be recognized after a reboot. I tried to assign the UPS to the second port, but the first serial port is still show in used by the UPS. Even after removing all UPS from the setup, I can't even use the terminal to serial as I get an error that the port is still assigned to the UPS even when there is no more UPS in the setup.

Did you ever get a resolution to this? Couldn't see anything acknowledging the bug in the v5 changelogs so guessing it's still an issue with v5.26?

Posted: **Mon Nov 04, 2013 1:32 pm**

I did note that this only seems to occur if you disable the UPS before removing. If you just remove then its seems to clear the "used by" state. We needed to access the UPS directly to update battery count at a couple of sites to give a more accurate run time.

What's new in 5.22 (2012-Nov-23 09:28):

*) wireless - fixed rare nv2 link stall;
So, how serious is this? Every links goes down now and than. Should I now upgrade or not? (I just finished upgrading to 5.21...)

Did the links stall under certain conditions? Or in general.
In the first case I would like to know what these conditions/configs where.... In the second case I probably need to update again soon.... (after not too many issues are being reported here...)

I'd like some additional information on this as well. I've noticed a problem where some NV2 configured access points would just stop sending/receiving data and would not start again until the interface was disabled and then re-enabled.

Does this fix that issue? Is there a detailed bug report we can see?

We have still this issue on several APs! We have everywhere version 5.26 with newest firmware, APs are mostly RB433L or AH with SXT or RB711 all upgraded to 5.26. Is there a solution for this issue?
