There are some few fixes for Nv2 that will increase the stability so If you are using Nv2 we recommend to upgrade the AP and the Clients to this version.why don't you guys write full change reports ? ? ?
Is their any changes regarding NV2?

What exactly is this change? Can I please get more info on this?*) l2tp - fixed problem with reconnects when it added multiple ip addresses;
Can you replicate it with a simple bandwidth test?with 5.24 and nv2 we have a lockup when data gets to 40mbs tx and 40mbs rx simultaneously

Have you changed MPLS MTU to make it work over pptp tunnel? PPTP adds overhead and reduces MTU.ROS 5.23 and ROS 5.24 start problem with protocol ssh in mpls , when is used pptp.

Was it working ok with v5.23?
I upgraded an RB2011 from 5.23 to 5.24 and then upgraded the firmware. Not only did it go smoothly, but a wireless ethernet bridge I had on the network is now able to connect without any dropouts (it was disconnecting every few mins on 5.23).A new RB2011 died after upgrade from 5.23 to 5.24...

This problem is battering me for a long time... I was just about to post the same complaint!with 5.24 and nv2 we have a lockup when data gets to 40mbs tx and 40mbs rx simultaneously

I updated one of our links (bridge/station-bridge with nv2 on x86 hardware, 2km distance, dual pol) - both ends - to 5.24...
After 3-4 hours passing traffic of about 80-90Mbps it suddenly stopped. Then, I just disabled/enabled the wlan1 interface on the bridge side of the link and it resumed for another 4-5 hours, then stopped again.
...before I downgraded back to 5.23 I did make a supout.rif file. I Will submit it to support...
Note: the link is stable with 5.23 ever since...(300/300Mbps)! Before the upgrade it was on ROS 5.21 and the link's uptime was exactly the same as the router's > 151 days!!

As per 5.23 thread, the cause was the new firmware 3.02, i myself now upgrade RB450G and 493AH to 5.24 using firmware ver 2.41 and everything runs ok.
problem with nv2 freezing was in 5.21 5.22 5.23 5.24,
if fw 3.02 is cause - what about some new fixed version?
btw is there any way how to downgrade to 2.14 without downgrading routeros to older version?
after that you just upgrade RouterOS and don't touch the firmware - you will have 5.24 and 2.41isnt that downgrading version?
And it is solution for problem?the RouterBOOT upgrade version can be shown as 2.41 if you have manually uploaded an older FWF file
Just tested on OmniTik - switched port to forced-off, then back to auto-on and the device powered up without any problems.by the way there is POE problem on Omnitik:
PoE settings on port auto on is not working, must be switched to force and now it works
nice bug
I was using it at RB450G and RB493AH, mostly for static routing, loadbalancing and traffic sharper. At ROS 5.22 and firmware 2.41 everything just fine, upgrade it to 5.23 and firmware 3.02 problem start to happen, my RB450G and RB493AH ether having enable and disable each several hours (sometime each several minute). So i have to find a away to downgrade and problem still exist after down to 5.22, then i try to downgrade to firmware 2.41, problem stop.gluetea,
on which board the new 3.02 firmware was causing problems?
So far, 5.24 has not locked up in over 100 RB800 AP's running NV2 connecting to RB711'sIn 5.23 I have wireless lockups in an 711GA-5HnD, nstream.
does 5.24 resolves it?
thanks
Yes, all our AP's and CPE's are on 3.02on all those RB800, did you upgrade FW to 3.02 as well?
You are not alone My Sextant,s i frozen too...5.24 + fw3.02My sextantG just froze its wlan,,, I was using ros5.24 + fw3.02
Now using netwatch to run a script to disable/enable.
Whats the advice please MT..
Upgraded some more stations, no abnormal behavior observed, the previously upgraded stations is rock solid.Hello Folks!
Testing two devices after reading about the problems with new firmware.
RB433 access point for a office landscape.
RB333 VPN router for many clients, refused to upgrade via "the dude" first time just reboot nothing in logs, second time it was successful.
After 24 business hours, nothing unusal has been observed.
When will we get a version that will fix the usermanager?What's new in 5.24 (2013-Feb-19 15:29):
*) l2tp - fixed problem with reconnects when it added multiple ip addresses;
*) wireless - fixed AES encryption speed issues (upgrade suggested);

I thought the same until I had to upgrade BIOS on one of my Intel server - after that Intel NIC on that router stopped hanging each 1/2 hour. on the other router after BIOS update I got max ~970 Mbps instead of ~850 MbpsBut isn't the "firmware" just the bootloader? How can that affect RouterOS?
older boards don't need it. the upgrade only fixes RB2011 related issues. each board has different RouterBOOT versions.In RB2011 i have bios 3.04 where is upgrade for older boards?

For me v5.24 with all upgraded firmwares on all boards works for now excellent
First day was strange, but after week i don`t see reboots or disconnects.
On few routers i make reset-configuration then setup from zero - works fine!
Good job! For now i testing v6rc11 on few boards and works too...
When final version of v6?
Hi
how much data are you moving on your wireless link
Does this mean it is better to stay with ver 5.19?I have the same problem. The link freezes every 2-3 days and 5.24 don't solve it. Now I use WDS and my link works fine at least two weeks.
Up to 50/20 Mbps via RB411UAHL+R52Hn at both sides.
You're right, it's only in relation to wireless links that use nv2 protocol.Does this mean it is better to stay with ver 5.19?
Or is this only applicable on wireless links
ThanksYou're right, it's only in relation to wireless links that use nv2 protocol.Does this mean it is better to stay with ver 5.19?
Or is this only applicable on wireless links
Please make sure that the AP and the client uses v5.24 and do the following steps, those will help to detect the problem and to find a fix for it:Always the same **it, AP stops transmitting data at any time! Clients are angry.
They do stupid things just type quote changelog: lcd - changed gamma, which gives greater contrast
Super, NV2 does not work, but most that I can adjust the contrast.

Try this: downgrade your firmware to the version 2.41.Hello Folks!
Today we started to recieve problems after deploying several RB751U 2HnD with RoS5.24 and firmware 3.02.
We have very frequent crashes, almost one every hour with autosupout files, we sent them in, lets see what is problem, we did have no problem with 5.22 for months.
We have several RoS 5.24 on RB195, RB333, RB750 and RB433 devices with not any problem notices since release of RoS5.24.
Same here on 5.24We've a RB600 and a 2011LS rebooting randomly every 3 to 6 days after upgrading to 5.24. All other upgraded devices seem to work.

only in a case where I m using Board as a AP with R52Hn + SXTs as a clients
I do have same problem with you guys that makes me confuse. There're always funny question like, this version is OK with one of my RB but why not working on my other RB.

We've 11 RB600 running without problem since update to 5.24 and one which reboots.No problems over here with 5.24 on an RB600A doing ipv4 routing, wireless nv2, vlans and ospf.
I have one RB951-2n in production and on this routerboard I have the 5.24 version of routeros.I do have same problem with you guys that makes me confuse. There're always funny question like, this version is OK with one of my RB but why not working on my other RB. Or something similiar question like that.
Of all the RouterBoard that I have, the most frustating one is RB951-2n. It comes with v5.19, and have wireless issue. I've try netinstall to v5.20, v5.24 and v6.0RC12, it solve wireless issue but gives at least 1 of this 2 issue to me.
1. It keep increasing the Bad blocks every several reboots
2. keep rebooting itself every less than 24 hours (even when I only connect it to 2 PC).
I try netinstall more than 10 times since I see some user in the forum say it fix their bad blocks eventually. But still no luck, worse it increase the bad blocks.
After a deeper research on the forum I make my own conclusion. It seems the result for every Mikrotik version varies for every RouterBoard type OR default firmware.
for example RB750 that comes with v5.19 may has different result for RB750 that comes with v5.12 when you upgrade them to v5.24.
Based on my silly conclusion, I do a brute action to my RB951-2n by Netinstalling every different available version. Everytime I see one of the stupid issue like increasing my bad blocks or rebooting by itself, I netinstall it to different version.
Luckily now I'm at v5.23, and haven't see any issue. No rebooting, bad blocks stays at 1%, and wireless is OK.
(still not test it with stressing data transfer but I'm going to wait for several days before stressing it.)
Why there's no version that works for all RB like a magic? still a mystery of the universe. LOL.

Major improvements to nv2
Yes we tried ANI on and off in multiple different configs. It seemed to be the combination of ANI off and Legacy rate selection that made a difference. The interesting thing is that we are running 5.23 and 5.24 on other links with no problems. The only ones with problems seem to be links with a great signal... Go figure!Can you confirm that you did not experiment around with adaptive noise immunity? I've been running advanced rate selection since last summer without a single lockup.
This also happens with it off.I also share the opinion that adaptive noise immunity could be causing nv2 lockups, therefore I recommend to turn it off and check if it resolves random wireless lockups.
I have lockups with adaptive noise immunity off on 3-4 Omnitiks till nowCan you confirm that you did not experiment around with adaptive noise immunity? I've been running advanced rate selection since last summer without a single lockup.

Yesterday I visited the place where 751u 2Hnd sit, logged in and started torrents from another PC to see what happened.
/tool profile show that a process called "flash" takes 100% CPU after a few seconds when packages start to come, then the device dies/reboots.
We do not have any proxy setup that uses flash disks.
I checked that we do not log anything to flash disks.
No scripts is using flash disks.
No smb that shares flash.
So the problem is process FLASH is taking all CPU.
I did simply replace the 751u 2Hnd with RB2011UAS-2HnD and all started to work normally!
However I also noticed that the new out of stock RB2011UAS-2HnD was preinstalled with RoS6.0rc13. We do not normally install RC and development versions of RoS so this device has to be migrated to production releases of RoS later then, a bad thing in production :-/
I will later try to reimage the 751 device using netinstall to see what happens.
Still we had not upgraded all devices to RoS 5.24 due to the issues we se people have with it and our own experience. We keep to the stable 5.22 exept on some routers (ppc based) which is on 5.24 since some time without problems so far.

I was with 5.22, upgraded to 5.23, I now (some links) upgraded to 5.24 (I also found out what I was doing wrong with it and I couldn't see the graps) and I have NEVER encoded any problems with any of the firmwares.
Has someone of you guys search it "deeply"?
Have you tested your hardware, YOUR instalation, your something that you made it wrong and now you have problems with it?
I can't "bait" that you have done EVERYTHING OK to MANY systems that you have and you have problems with ALL of the systems (even DIFFERENT systems).
Are you 100% SURE that you have done EVERYTHING OK as for settings and hardware?
Maybe you're putting in TOO MANY "complicated" settings and you're "driving crazy" your links with that.

Data Rates - Rate Selection - Legacy
Data Rates - Default
NV2 - Tdma period size - 2

We don't use NVstream, but we had problem with wireless freezing on our RB800 with FW 5.24.
Switching DataRates to Legacy solved it! (for 4 days we haven't had freeze yet)
I have the exact same issue with this Routerboard model.Hello again!Try this: downgrade your firmware to the version 2.41.Hello Folks!
Today we started to recieve problems after deploying several RB751U 2HnD with RoS5.24 and firmware 3.02.
We have very frequent crashes, almost one every hour with autosupout files, we sent them in, lets see what is problem, we did have no problem with 5.22 for months.
We have several RoS 5.24 on RB195, RB333, RB750 and RB433 devices with not any problem notices since release of RoS5.24.
We have reports here and on the topic of 5.23 saying about problems with the new firmware, the 3.02.
But ... on my home router ( i have this version here on a 751u 2Hnd ) i had weekly reboots and a revert back to 5.22 ( I come from the version 5.16 ).
Yesterday I visited the place where 751u 2Hnd sit, logged in and started torrents from another PC to see what happened.
/tool profile show that a process called "flash" takes 100% CPU after a few seconds when packages start to come, then the device dies/reboots.
We do not have any proxy setup that uses flash disks.
I checked that we do not log anything to flash disks.
No scripts is using flash disks.
No smb that shares flash.
So the problem is process FLASH is taking all CPU.
I did simply replace the 751u 2Hnd with RB2011UAS-2HnD and all started to work normally!
However I also noticed that the new out of stock RB2011UAS-2HnD was preinstalled with RoS6.0rc13. We do not normally install RC and development versions of RoS so this device has to be migrated to production releases of RoS later then, a bad thing in production :-/
I will later try to reimage the 751 device using netinstall to see what happens.
Still we had not upgraded all devices to RoS 5.24 due to the issues we se people have with it and our own experience. We keep to the stable 5.22 exept on some routers (ppc based) which is on 5.24 since some time without problems so far.

Others (RB433AH, RB450, RB750G) work perfectly normal with v5.25 and Firmware 3.02.
Did you find any solution?
Thanks.
Hello,On my router board I solve my problems with this configs

So to recap:Hello,
problem lies in fact that this RB751U has exhausted it's hardware capabilities.
RAM capacity on this router simply ain't enough for this task. If you would
replace this unit with one that has 64MB ram or more, that would solve this
problem. If router has bellow 10MB of free ram on average replacement with more
powerful unit should be considered.

I made it clear that the issue occurs to 10 offices and I only managed to get 2 supout files, since when the problem occurs the router crashes and autoreboots.Are you sure you have only the default config the boards ship with? If yes, email again to support and clarify this point. It might be a misunderstanding. Torrents are known resource abusers, make sure to limit the number of connections in your torrent client. This will solve many problems.
After upgrade, my Router no "bip" when power on and can not connect via Winbox. I try to hold reset button but nothing happen.problem with nv2 freezing was in 5.21 5.22 5.23 5.24,
if fw 3.02 is cause - what about some new fixed version?
btw is there any way how to downgrade to 2.14 without downgrading routeros to older version?
Here You go (Use WinBox) :
1. http://download2.mikrotik.com/routeros/ ... e-5.22.npk
2. Copy and paste it on "Files"
3. Go to /system/package then click "Downgrade" then it will reboot, or you must reboot after that (/system/reboot)
4. Check Your Version it's must be 5.22.
5. Then go to /system/routerboard, you will notice that "Current Firmware: 3.02" and "Upgrade Firmware: 2.41"
6. If Current firm are high version than Upgrade firm then you can click "Upgrade" and make sure it done.
7. Then reboot your router from /system/reboot
8. After reboot, check /system/routerboard you'll see all firmware version now 2.41.
9. Done.
