forget what i said earlier, i know the culprit is the cpu was somehow set to 100mhz after upgrading from 4.17 to 5.10 and then 5.11. that's why it took down throughput when running winbox.how did you test? what data was transferred, how, and from where to where?mikrotik could not achieve maximum bandwidth throughput by accessing Rb450G from LAN if using windows machine (7 pro sp1 64bit) (30KBps to 1Mps range only, mostly below 1MBps).
funny thing, after tested from ubuntu machine (11.10 desktop x86) the thoughput went through 6MBps!
the router eth0 is Gigabit, so is the client (windows and ubuntu). is there known limitation/compatibility for mikrotik and windows bandwidth throughput?

looks like there is something in common between all your routers. none of our test devices has crashed, we even have some running in our live network.
it's possible you all four use the same feature or function. can you all describe your configured settings in a few words? what did you all configure? do you have queues, tunnels, some specific feature?
What does this mean? The dhcp-client request new IP etc. after ethernet link up event?*) dhcp client - renew dhcp lease on ethernet link up event;
And i found new feature!I have 2 Routerboard 1100AH upgrade to v.5.11 and every day crash
i guess you are experiencing the same symptom with me. take a look at system resource, check the cpu frequency, i hope it's not 100Mhz.Hello!
Faced with the device RB450G that after you upgrade from version 4.17 to any version 5.9-5.11 is the performance drop by 2-3 times (at the 4.17 rate was about 200 megabits, but now more than 50 does not rise, due to the 100% CPU usage)
It is also sometimes result in an error of the kernel.
What can follow any responses to advise, if I had to re-create all the rules, after resetting all settings.
The same thing, x86 platform - router was rebooted without proper shutdown, at least two times in 24h. It was working perfectly until ver. 5.8. After upgrade to 5.9 - 5.10 - 5.11, rebooting continue constantly... Supout.rif file sent to the support.I have 2 Routerboard 1100AH upgrade to v.5.11 and every day crash
Problem with my x86 - After 4 days of the upgrade to v5.11 my HP Proliant ML110 G6 core server is stopped and frozen as well as with earlier version v5.7. Just press on the reset has helped to start server again..nothing was changed in this area, so I can't see why X86 would reboot on v5.11 and not on v5.8
No, like the frequency has not changed.i guess you are experiencing the same symptom with me. take a look at system resource, check the cpu frequency, i hope it's not 100Mhz.
you could set the frequency back to its normal value via command line if it happens to be set 100Mhz after the upgrade. or through the gui in winbox on the routeros 5.x version. don't forget to upgrade your firmware too.
oh okay, so the cpu frequency has nothing to do with your lower throughput. ever tried to disable all firewall rules and test it out temporarily?No, like the frequency has not changed.i guess you are experiencing the same symptom with me. take a look at system resource, check the cpu frequency, i hope it's not 100Mhz.

Yes, tried on the number of rules does not.oh okay, so the cpu frequency has nothing to do with your lower throughput. ever tried to disable all firewall rules and test it out temporarily?

clear the configuration and recreate it step by step. after all that is mayor version upgrade that is not done to initial version of major release.
it seems the problem is related to vlans . right ?sigxcpu, MichelePietravalle, nik247, Alessio

My RB750. ROS version 5.11. firmware 2.37.My RB750 upgraded successfully,It works well till now.
But I found a warnning message in the system logs.
"System rebooted because of kernel failure"
Every time I start or reboot the router,It's always in the first line of the logs.
Is this a prompt bug or a serious proplem?
I'm sorry mikrotik support, I wrote "internal server error" for my android. but with browser opera version 11.50 build ADR-1111101157 work fine anytime . by the way in usermanager "userman - show overall totals, show user totals if user has more than one entry" like changelog 5.7 did'nt work;
that's just info, thx
I am seeing a similar problem and error messages ("system rebooted because of kernel failure"). I have a new RB450G which came with 5.2 installed. I upgraded to 5.11 and entered my configuration which is relatively simple. It has rebooted twice in the four days that I have had it. I also have a new RB493G with 5.11, albeit with a different configuration which has been fine so far. It appeared to generate a supout file so I'll send that to Mikrotik support.I have 2 Routerboard 1100AH upgrade to v.5.11 and every day crash
it looks like RouterOS looses HDD (in my case, it's USB Flash, 8G too ) - either now, or a bit later you will find out that Files window is empty, and Terminal window hangs after opening. the only thing that will fix it is reboot; and the only problem - it should be hardware reboot, because on rebooting remotely (via WinBox) router will just hangI've run into an issue tonight where I couldn't log in to my x86 v5.11 router with my configured username and password. I had deleted the "admin" user at initial setup but the router sometime in the last 24 hours decided to remove my username from the users list and reactivate the default admin user. This had the unfortunate side effect of letting someone unknown to me log in to my router early this morning via SSH which was configured to allow logins from anywhere, unlike every other service which is locked down. Fortunately, this person didn't appear to have changed anything. After setting things back (with a new password just in case my password was compromised) the system returned back to only having the default admin user in it within minutes of me changing the config several times. Also, looking at the license of the router shows no license. /sys lic print literally just prints a couple returns and back to a prompt. The loaded license was a level 5.
But why should accounts(/etc/passwd?) revert to old values? I would expect that all accounts would be rendered unusable in that case.it looks like RouterOS looses HDD (in my case, it's USB Flash, 8G too ) - either now, or a bit later you will find out that Files window is empty, and Terminal window hangs after opening. the only thing that will fix it is reboot; and the only problem - it should be hardware reboot, because on rebooting remotely (via WinBox) router will just hang
why would it be in the release notes? this is a specific suggestion, just for your situation.Is it so diffilcult for Microtik to write down release notes. For example that it is necesarry to update x86 pc's firmware before using new 5.x versions.
As support informed hdd of usb loses is due to old x86 pc's firmware.
that's right. i forgot to mention,we are also running v5.11 on RB433AH with two R52Hn cards - no problems at all.so i'm not alone on this
anyway, before i upgraded to v5.11 on the main router, i had it tested on an unused RB750. suprisingly it doesn't crash at all, i keep it running for 24 hours. it has no any firewall rules added, it is on a clean default setting.
this may be unrelated to routing at all. RB1200 used to have some problems that were fixed in RouterBOOT and RouterOS upgrades. So, please upgrade RouterOS to v5.11 and then issue command :"/system routerboard upgrade" and reboot. After this, your problems will be gone.I use to control RB1200 routed customers have a lot of freezing and rebooting problems.
Well, Is it safety to use 5.8 instead of 5.11 or it should not be any problem in NAT/Routing (BGP) in 5.11?this may be unrelated to routing at all.
can you please update http://wiki.mikrotik.com/wiki/RouterBOOT_changelog
for example RB433 now has RouterBoot v2.39 and on the web page there is still 2.37 as the last one described.
Thank you in advance!!

there are no public changes. added support for unannounced products.
whats unclear about this sentence? you wanted us to publish the names of future products in a changelog?added support for unannounced products.
I think, he wanted to say "Why do you release firmware for unreleased hardware?"whats unclear about this sentence? you wanted us to publish the names of future products in a changelog?added support for unannounced products.
Thank you normis on your fast reply!!there are no public changes. added support for unannounced products.
i wish i had taken a photo of it, but i didn't. i can't help you at this moment too, as my clients are gonna kill me if i have another crash again. i had too much crashes + electrical problem + wireless signal interference + cable replacements on BTS + firmware upgrading / downgrading, and all these happened on this january . they had too much problem from meIf anyone is experiencing crashes with X86 systems, please email us a photo of the crash (on the monitor) and the supout.rif file. This applies especially to those of you who said that downgrade helps!
Exactly.I think, he wanted to say "Why do you release firmware for unreleased hardware?"whats unclear about this sentence? you wanted us to publish the names of future products in a changelog?added support for unannounced products.
we have no reports in support. only complaints in forum. please make photo of crash, and send to support with supout.rif file. also tell us last version where it worked fine.Sorry for bothering... But does support have any update on problem with 5.11 running x86 system?
We have only remote devices, no monitors or anything... But we have console connections to our mikrotik B-RASes. On consoles we have nothing. Like common reboot... How to get any debug output, kernel oops...or anything? Maybe some kind of netconsole?siprox in your ticket you don't give us any information. we need at least photo of the crash output on the monitor
Dear friends!i can tell you that mine is not just black screen. there's a lot of error message on the screen, and somewhat i clearly remember that the last words are "kernel panic".
On wire or radio? And do you facing reboots?This release may be still got some bug.
After I upgrade from 5.7, my company found the network delay change to so big.
The traffic show very big.
Wow! Weird... Do you have strange reboots or hangs?After upgrading RB1100AH from 5.8 to 5.11 I have large latency spikes 5-20 ms across bridged VLAN's on port 11/12, previously latency was 0-1 ms.
I am using the RouterBoard as a transparent firewall at my network edge, bridging 4 VLAN's through 4 bridges on port 11/12.
Attached is an screenshot of the latency spikes before and after the upgrade from our network monitoring.
If it works, do not upgrade. If zou reallz want to upgrade go to 4.17. If zoy really need something in 5.xx upgrade to 5.4, but only if you really must.Hello Guys... Im new here...I started to work in a School and they have Mikrotik 4.11....
So i want to upgrade.. but when I do it??? It will reset all the configuration??
Thank you Any help will be aprreciated
Thanks for the info. But we have big troubles with bras`es on x86 with 5.11 software. Spontaneous reboots. Nothing helps... I wonder, does this problem exists on 5.10 or 5.9?If it works, do not upgrade. If zou reallz want to upgrade go to 4.17.

Upgrade will usually keep configuration intact but in newere versions there is increased probability that config will be messed up, so beackup both binary and command mode before upgrade.
i had experiencing randomly reboots on version 5.9, 5.10, 5.11 to. all that same. back to 5.8 and then normal again.Thanks for the info.

So whats up with the latency issue, and why havent you pulled the release, as clearly it is not stable?we have made a pre-release version with a potential fix for x86 reboots. email support to gėt it.
what latency issue? the x86 issue that I mentioned, affects only specific configurations. we only have received 3-4 complaints to support, and maybe 5-6 in the forums (clearly 2-3 people have no interest in reporting the issue to support)So whats up with the latency issue, and why havent you pulled the release, as clearly it is not stable?we have made a pre-release version with a potential fix for x86 reboots. email support to gėt it.
