are the openvpn bugs introduced in 5.14 fixed? still using 5.13

I can see changes in wireless. I'm using Mikrotik as home AP, after install 5.15 I getting better throughput with Intel wireless cards. Now I can obtain about 80Mb/s HDX tcp bandwidth in b/g/n mode (20Mhz). Also I see changes in energy power saving. Finally, my computer is able to connect with mobile devices which are use energy power saving and are connected to the Mikrotik AP.

Unfortunately, energy power saving is not so good in comparison to the access points of other manufacturers. My mobile phone eats battery faster when connects with Mikrotik..

Great.. There were two bugs in 5.12-5.14 that affected me greatly and I didn't know about them.. Well you live and learn as they say..

There may be broadcast frames hitting your client devices. Therefore the higher battery consumption for them.

Also in v5.15 is support for WiFi multicast to handheld devices.

I'm not sure why this was omitted from the list of fixes.

Previously, v5.x and v4.x did NOT support WiFi multicast to handheld devices.

See http://forum.mikrotik.com/viewtopic.php?f=7&t=59235 for detailed information.

kkolev, wireless improvements were added to 5.15.

NAB, jandafields, you can attach USB device to RouterBOARD USB port and operate it by Windows computer.
However, this option is added to v6.x only, changelog entry was added by mistake, this option applies for v6.x

jcem, do you have the latest Winbox version?

Caci99, honzam, e-mail has been sent only today, thank you for the concern.

estdata, what is the problem with the CPU stability?

Posted: **Mon Apr 23, 2012 11:33 am**

In the future, can you make Winbox-lite version or Webfig-lite version for GSM (no operating system Android or Simbian)

Posted: **Mon Apr 23, 2012 11:34 am**

why isn't current webfig working for you over GSM? works fine for me.

if you want lesser number of menus, use Webfig SKIN editor to make a lite version yourself

Hello guys,

I got a strange bug in 5.15:

when I create users through terminal, say with

/user add name=xxx password=yyy group=zzz

, the user actually gets created without a password (so anyone can login as xxx).

Workaround is to use

/user set xxx password=yyy

but that still leaves some time window for anyone to login into the router (and do ugly stuff.)

I actually hope I messed something up myself - this isn't a bug I would expect from MikroTik; but the router (it's rb433AH) has been upgraded absolutely cleanly to 5.15 and seems perfectly okay in any other way. I'm gonna test it on some other routers ASAP, but I don't have any other 5.15 available yet.

Can you please confirm this or give an advice on how to get rid of this annoying behavior?

Thanks in advance

I just tried this on my SXT-5D and it is real. This is very serious issue.
Mikrotik, please fix it ASAP.

Posted: **Mon Apr 23, 2012 9:14 pm**

The 100% CPU bug in v5.7 when DHCP was on a disabled interface was a VERY SERIOUS bug. Unless you searched the forums, you would have suddenly have a useless router with no warning or anything from Mikrotik. This happened to a lot of unsuspecting people.

It took them 6 weeks to fix that bug!!! So, I would expect a fix of this serious password bug in 6 weeks or less.

Posted: **Tue Apr 24, 2012 7:59 am**

Major problems with APs -> CPE stops passing traffic and uptime column times are way out with the actual - using RB493s and RB433s.
Backing down to v5.14

On the otherhand - Backhauls seem to be great and APs that do NOT time out are servicing the CPEs better then ever

/user add name=xxx password=yyy group=zzz
, the user actually gets created without a password (so anyone can login as xxx).

I can see the already same for 5.11 using on my 493G. When I added new user trough winbox, the password will be changed to blank (deleted even for admin) and anybody can enter to setting only using name. I was very surprised when happened first time, because I can't join using my saved password. Then I check to join using only name without password and it works. So only one way is to check immediately to join and insert correct password.

Yes, but this was fixed in v5.12. Now the bug has returned in v5.15, but only in console. It works fine in Winbox.

I'm sorry to hear about bad experience with 5.13 version. Next time immediately make support output file and send it to us, otherwise it is impossible to identify the source of problem, and whether the same issue might be present at 5.15.
Install MikroTik RouterOS 5.15 on your router, contact support department (support@mikrotik.com) in case of any problem.

I experienced this too on RB751U-2Hn, used my normal script to do my setup working flawlessly for some time now. But when I use it now, I have to manually set the password afterwards, if not the password is blank!

ap brigde to ap bridge on 435g and 433 stops working. link gone. changed to wds slave on one side and link stays on. we thought our dsl lines were faulty because data troughput goes from 4mb to 0mb for a few minutes. If you like a black monday upgrade to os 5.15 otherwise stay on os 5.14

Hello Folks!

We did upgrade (5.14 -> 5.15 ) two customer routers (wired) and one router (wired) that takes a lot of traffic has firewalls and priority queues etc. All seems to work like normal with them at least.

In test LAB setup with one wireless AP and five clients we did not notice any problems either.

I will stay with 5.14 in production yet some time to see what happens both in forum and in lab.

Calm down, if you can't downgrade then simply export your configuration, do 5.14 netinstall, and import your configuration. Easy!!!

We upgraded 3 systems of RB411AUHR + MC8705 3g modems on ATT from 5.14->5.15 with the systems running and online.
This was a big mistake that we won't make again.
This "bricked" all 3 of the systems as the upgrade never completed after over an hour of waiting each.

I had to run netinstall to get them running again ( the nand kernal would not load )

I netinstalled 5.15 and fully reconfigured from scratch using the LTE interface for the MC8705 ( I love it ) and they are now working in the testlab.
I will not move these systems into production until things settle for a while.

Why did you upgrade all 3 at the same time? Why didn't you stop after the first one failed? I never upgrade routers without a configured backup on hand... the cost of a backup router configured and on hand is nothing compared to a network down during a netinstall.

Not in v5. SCEP is added starting from v6beta2.

Posted: **Sat Apr 28, 2012 12:49 am**

Just upgraded an RB411U with a Sierra MC8700 installed. As stated in the changelog an LTE device now appears and the ppp device has stopped working. Unfortunately I cannot get the LTE device to work at all - communication with the device seems to be completely broken, I'm thinking this is due to there being no way to enter channels into the LTE interface in winbox?

Is anyone else able to get the MC8700 to work with 5.15? Will have to downgrade I guess. Have emailed supout with and without modem to mikrotik.

Wireless card AP mode stoppes after some hours. same with RB433 three wireless card ap stopped working i have to reboot.
same RB411AR, RB433AH, RB411R and RB493G.

I HAVE TO DOWNGRADE ALL OF THIS BOARDS
Same situation, after a day or two stops traffic to users. I had to go back to v5.14 and everything is stabilized.

Goran.

I had to so the same thing - except my MT->MT backhauls they work even better with v5.15

Also but on x86, downgrade back to 5.14. PtP work ok no problem but PtM just stop working random.

I'm using RB411, 411AH, 433, 433AH, RB600, RB600A, RB435G, in all board PMT system are not works, specially were I have to many direfrents CPE's brand, on some only there are UBNT CPE, but before 3 o 4 hours, customers links down, I have back to 5.14, really I had a black monday when I was upgraded to os 5.15, on RB1100 an x86 systems seems stable, and in PtP systems using NV2 too.

regards.

Seem that my RB1100 also stopped after a while. I'll try to investigate later today, first some gardening.

RB333, RB433, RB433AH, SXT, OMNITIK works fine for me, RB1100 difficult, and my RB800 are not yet upgraded.

Hi There!
I am using mikrotik on x86 and I have upgraded to Mikrotik v5.15!
since then, monthly subscribers can't show the remaining time in session time left and status

Are you talking about the User Manager mate? And with 5.14 these were fine?

in the client Status even in Winbox i can't see the time left only for the clients who has unlimited for 30 days? And with 5.14 these was fine?
Note: i just instal the 5.15 and upload the config but for the userman, i started it as fresh

Same problem here. If you disable the wireless interface and enable it, it starts working again. I was in a hurry and didn't have time to get a suppout.

so far, some i upgraded without issue just the mib file not work properly...

Issues that I have had so far with 5.15, bridge device not always working correctly, have IP bound to it and DHCP, bridge to an Ethernet port and VAP wifi interface. Have DHCP set to 10 minutes for lease time (been like that for years without problems). (Additional note, using bridge with VLAN seems to have a similar connectivity problem at times, but goes away much faster.) Was running on a RB153, upgraded to a RB450G same issue, made config from scratch. What looks like is happening, is DHCP is timing out and renew is taking too long so client gets limited or no connectivity, and then it starts working again. Second, WIFI with mobile devices has been unstable, even on my RB751G at home, keep getting 'disconnect, group key exchange timeout' in my logs and device disconnects and takes forever to reconnect. Have only seen this problem so far with 2.4Ghz devices. Tested with laptops (mostly intel wifi cards as that is what they come with) and even on my Nexus S. Going to be rolling back to 5.14 today if I cannot make everything behave well enough till next release.

We upgraded to Router OS 5.15. Links stop working and data through put was non exsisting! The new release affected only the DBii F50 pro and F50N pro on Rb 411,433 and 435G. The upgrade took a Tx/Rx signal from -77/76 to -89/88 and -81/81 to -89/0 disconnecting. Problem was solved by resetting the F50's making connections again. We discussed the problem and came to the conclussion that our links started to drop since we installed Router Os 5.14. We still busy going to rural clients to undo upgrades and to reset F50's.
The R52hn was still working and links stayed stable.

Posted: **Mon Apr 30, 2012 9:49 pm**

Actually the F52N-PRO is the card I am using in the AP that has dropped a few times on me. For the most part it is up but I am still having the occasional drop.

mine is a f20-pro that is stopping...

Posted: **Tue May 01, 2012 10:23 am**

I agree with the Dbii F50Pro issue. Have had to downgrade (to 5.14) a 411 and 433 that have these cards installed. The cards suddenly drop connections and refuse to allow reconnects. Disable and enable the card, all is normal again. No pattern to the time between the drops, can be 2 hours or 2 days.

Hello Folks!

There is defenitely some problem with ROS5.15 and wireless, we will rollback all updated now.

Directly after upgrading some customer devices (wireless) they started to behave bad, customer complains about internet comes and goes, the connection drops etc.

On all wired routers there is no reported problems so far, but we will rollback them anyway.

Anyone who knows what this is ?

Posted: **Tue May 01, 2012 4:45 pm**

I sent in two supouts on the Mikrotik stops passing traffic issue. Looks like there is a very noticeable increase in memory used just prior to the stop. So I sent in a high memory supout then and after reboot. Boards have been 433AH and 411AH with XR2s. APs in bridge mode. I have had three of them do this and I don't seen anything common between the three other than the memory issue.

Maybe the supouts will help them.

My experience:

Work:
5 AP - RB751U-2HnD --> 5.15 --> all is ok !
1 Gw - 433UAH --> 5.15 --> all is ok !
1 Gw - RB110AH --> 5.15 --> all is ok !

Home:
1 Gw/AP - 433UAH --> 5.15 --> all is ok !

Posted: **Tue May 01, 2012 8:24 pm**

For those that are having issues with wireless, disable the periodic-calibration on the AP and on the CPE.

If it helps please give feedback.

Had problems on RB751G, upgraded to 6 Beta 2 and all problems that I had went away. Wireless is now stable, with both notebook with intel wifi, and nexus S phone. Made no configuration changes after the upgrade.

Hey Normis,
How do I get my hands on v6.2beta? I'd like to give it a try!
Thank you,

But what version did you upgrade from? 5.15 supposedly has all the wireless fixes that 6b2 has.

Posted: **Wed May 02, 2012 4:33 am**

5.15 i had all the issues and then switched to 6 beta 2, so far in the last 24 hours i have had no problems with connectivity

We have about 15 RB751, RB493, 411 ... and also went down to 5.13.
5.15 worked sometimes. But lot of the WLAN Access-Points we where unable to connect. One could see it. But Windows was unable to connect. someone earlyer in this posts sayed BRIDGE is problem. But what ever. We hab some trouble and BRICKED 2 RB751 when downgrading.

you can't "brick" a routerboard, please clarify what happened. also there is no "bridge" problem in v5.15

These rules are not needed. Block 136-137 and 445 (CIFS) and that should be fine.

one of my wireless adapters witch is set as an access point, suddenly blocks client connections and on registration table shows big numbers on "last activity" column. when i disable wireless adapter, and enable it after, everything works perfectly for couple of hours, then again the same problem. I have to mention that everything works OK with previous version.

Yup, 5.15 is broken. Good results with 6.0b2

Posted: **Thu May 03, 2012 12:08 am**

are you positively sure about the latest beta version?

Posted: **Thu May 03, 2012 12:12 am**

What do you mean by sure? You have to try stuff for yourself.

Mikrotik doesn't recommend using 6b in production environments... but their "stable" 5.15 is bad anyway...

Read around here on the forums, you will see various people that are getting good results from 6.0b

Hello Folks!

Do I dare to rollout ROSA5.15 on our production AP's now
All wireless is nv2 point to multipoint networks ?
Is there any who had problems also with wireless nv2 ?
http://forum.mikrotik.com/viewtopic.php?f=7&t=60980

We have no such problems, links are very stable (usaly they are up till next routerboard versions is loaded). We did frequence scan and correct our channel separating on all AP's also splatter effects taken in to calculus and we use directioal antennas with H polarization.

Here we have some problem with RoS5.15.
RoS5.14 is 100% stable exept it generates some autosupout files now and then, maby every second week for the full park.

...I wish I have a 5.14 or earlier npk files...

I'm not sure how many others are still seeding it, but this link still works.

new in 5.15

/interface wireless> multicast-helper=

description ?

Checking this box will send multicast messages in unicast mode, thus greatly increasing the probability of correct delivery, since unicast packets are acknowledged by the receiver and resent if garbled.

This is only useful if you have a small number of clients. If the number of clients is large, the benefit of multicast is lost, since there will be a separate data stream sent to each device associated with the AP, rather than a single multicast stream.

I did some of the testing on a pre-release version of 5.15 to test a multicast feature fix that was reported here.

After many iterations, the multicast feature worked again, having been absent since ROS v3. However a new problem arose: the AP would randomly freeze.

I've been testing to help Mikrotik fix this problem for about a month. I've sent them many, many supout.rif and other documentation. They have seen the AP freeze in their lab, but rarely. I see it nearly every day in my lab, but sometimes I test for a few days and it doesn't fail.

I originally thought the AP freeze was caused by my high speed multicast transmissions, but having read the many reports on this thread, perhaps this is a protocol-independent problem.

I suggest anyone who sees this problem to make a supout.rif file, preferably while the AP is frozen, and file it with a support request to Mikrotik. I have found them to be very responsive if you provide details of the failure.

Many of you can fall back to v5.14, but I need the multicast feature which is only in v5.15, so I'm stuck with AP freezes.

My experience has been that disable/enable of the AP restores it to normal service.

As Normis has said before, the best way to get support for a bug is to contact support@mikrotik.com with as much documentation as you have.

Perhaps someone should start a new thread dedicated to just the AP freeze problem in v5.15.

Version 5.15 is broken.

My AP has been running for years. I just upgraded yesterday and the problems started.
My AP is a RB433AH - Bridge AP (no nat at AP) (average CPU load is 0% to 3%) - two 2.4 Ghz wlans (B-Mode only) - 70 to 80 connections at any time normally about 40 connections to either wlan.
Note - I own all client radios - outdoor antenna - 3 to 10 mile shots.

What happens is one of the wlans (or both) will stop talking - but there are still client connections.
When there is a problem --> Using winbox Wireless-Registration -- under the "Last Activity(s)" column -- all clients show a value between 56000 to 57000 -- none of the clients on the wlan are talking.

I attached a file which is a screen snapshot of the winbox showing the above.

When I disable then enable the wlan, all clients reconnect and start talking again (no reboot needed).

I have seen this three times in less than 24 hours now.

I do not have easy access to my mikrotik AP - it is located on top of a mountian 20 miles away.
Can I remotely downgrade to 5.14 or should I upgrade to a version 6 beta version?

Thank You MT staff

The "set always-allow-password-login=" addition to SSH is much appreciated.

(so ssh in 5.x works like all previous versions and most linux machines allowing both password and key based access)

To downgrade from 5.15 to 5.14 - do I have to use netinstall or will winbox do the job for me?

The problem 5.15 APs are remote and hard to get to - thus I hope I can remote downgrade to 5.14

I downgraded from within the dude on some wireless routers 90Km away, just picked 5.14 and upgrade, guess it also works with winbox. The router restarted and 5.14 was there, no problems.

one of my wireless adapters witch is set as an access point, suddenly blocks client connections and on registration table shows big numbers on "last activity" column. when i disable wireless adapter, and enable it after, everything works perfectly for couple of hours, then again the same problem. I have to mention that everything works OK with previous version.

I've got the same problem with R52H.

Drag-n-drop the v5.14 package to files and then go into the "packages" link and use the "downgrade" button - all in winbox.

BTW - currently running v6beta2 on select towers - only a couple of glitches - seems to perform very well - keep up the good work MT!

Just had a glitch actually about an hour ago - AP did the same thing that v5.15 does - shows connections with a crazy time associated and does not pass traffic - reset interface and all is well. Very strange! Also had one of our primaries loose Ethernet ports but not direct RF connections. We are running v6beta2 on one primary Back-haul system that encompasses 12 back-hauls on p-t-p and p-t-mp and also quite a few secondaries and edge towers with APs.
No problem with remote upgrade and downgrades so far and three failures on systems that haven't glitched since the v5.15 tryout.
One thing in common - all were RB433 but in separate configurations - 1. only 5.8bh with APs connected via ethernet 2. two different edge with 5.8 BH and 2.4 AP (BHs never fail but APs do)
Total of three failures now.

Thank you,
Rod

Another screenshot on another AP.
No data on the ones with big numbers.
Run a scan on the interface and the connections are reset and they work - kick the individual connections and they reconnect but no thru-put.
Rod

Exactly same problem wireless card AP mode stoppes after some minutes. Had to downgrade all nodes.
Any idea about which bug causes this?

FYI - I am finding that the problem is on RB100 series & RB400 series & RB500 series & RB600 series

also - on APs with two wlans (2.4 ghz wlans) - sometimes the problem is just one wlan

IPSec is broken since 5.14, flushing doesn't even work anymore. I need to reboot the router multiple times a day. I'm downgrading to 5.13.

Posted: **Mon May 07, 2012 8:24 pm**

IPSec is broken since 5.14

I also have problems with IPSec, tunnel worked flawlessly for months,
but now establishes and expires after 10 seconds

(configuration was not changed in any way).
This occurs when MT is initiator, not responder.
Does someone have similar problem???

OK - now having more troubles with AP's with the beta on them - rolling back to v5.14.

So - is there an active Mikrotik staff person looking into the 5.15 AP wlan lockup problem or is this problem so far just noted in this forum?

You have to contact the MT support for that answer (if you are eligible to do that directly). Forum here is mostly for venting purposes.

there seems to be a bug whereby on 5.15 on an rb411, the serial to ssh passthrough does not work (special login)
it works on 6.0b2

Version 5.15 is broken.

My AP has been running for years. I just upgraded yesterday and the problems started.

So why you upgraded a system that have been working for running/working for years?

Posted: **Wed May 09, 2012 5:43 pm**

I also had wifi problems with 5.15 on RB493 .. clients all got disconnected (unicast key exchange timeout) and clients were not able to connect again but the ssid was still broadcasted. Looks like "one-way" transfer ... disable/enable of the wifi interface fixed it for some days.

i downgraded to 5.14 again and everything is fine.

Because newer features might yield better performance? For compatibility with newer, possibly not-MT products? Just because a system works doesn't mean it is never necessary to change it.

FWIW, I posted here about a change introduced in 5.x (and continuing at least into 6.0beta2) that rendered our AP-to-AP backhaul links unstable, meaning that the equipment carrying the bulk of our traffic has been stuck at 4.17 while we look for a solution.

5.15 has been pulled from the downloads, it seems... (?)

Posted: **Wed May 09, 2012 10:43 pm**

Meanwhile version 5.15 disappeared from download page.
Obviously it is considered fake officially.

The bugs were stable.

It's actually a good sign that they pulled it; it means they identified a definite problem.

After numerous exchanges of email and submission of many supout files, I've just received a beta of v5.16 which Mikrotik feels has fixed the freezing AP problem.

So far, the AP hasn't frozen, although it will take awhile to convince ourselves that it's really fixed.

The Mikrotik folks worked hard to get this fixed quickly, and I appreciate their efforts.

Posted: **Thu May 10, 2012 7:42 am**

Thank you all for sending supout.rif files to support. We have able to identify the wireless problem, therefore we removed the version from the webpage. If you have this version running, and have not seen any wireless issues, you can keep using it, otherwise this version is working fine.

Posted: **Thu May 10, 2012 10:56 am**

If anyone wants to test the fixed v5.16 before we released, contact support please

On 751g-2Hnd with AP enabled after 3 days of running no problem i see 2 wireless networks same SSID, one encrypted the other not.
It should be just the encrypted one.

Dear Mikrotik,

would you please inform us if there are any improvements on nv2 wireless link stability?

Thanks

Posted: **Fri May 11, 2012 12:27 am**

Dear Mikrotik,

would you please inform us if there are any improvements on nv2 wireless link stability?

Changelog does not list anything wireless related, so apparently there isn't nothing for NV2.
