Hi,
I have upgraded all our MT 433,600 to 3.25 about week ago.
Because it is about 290 devices I have used perl telnet to command
them to download new os from my ftp and synchrionised to reboot at one time.
On ftp I had only routeros-****3.25.npk common package build on jun/15/2009 10:07:37.
After rebooting 4 of 293 didn’t load some modules like wireless or dhcp and
I had toupgrade manually again and load backup.
I have also set in scheduler to reboot with interval 3days - ant it was dramatic decision.
Yesterday I saw a horror All my Dude was RED.
About 40 devices lose their settings excluding some settings like System Name, Ip addresses.
They have 3.10 or 3.18 before. Some have losed only their gateways or had very old ip address
which was used 3 months ago. I thought 3.25 it is stable.
I am writing it to warn other admins.
warn about what exactly? this is not normal and doesn’t happen. maybe you did something wrong, quite possible that your script didn’t transfer the complete package, maybe transfer was broken. this kind of thing shouldn’t be done without care, you need to do planning and use appropriate methods.
As I wrote.
Upgrade - can happend bad upgrade - OK..
But :
Every 3days mikrotik reboots at 2.30 am. What should I do wrong ?
/system reboot
Its normally loses settings. - Something is wrong and I want to see if
other mt users have the same problem with 3.25.
if it’s exactly at that time, you should check configuration if it’s not scheduled to do so, of if you have any hardware/electricity issues.
if it loses config on reboot, this is completely abnormal and you should inspect hardware. it is so on all devices or only on some? compare them and see what’s different.
I’m sorry for pure english.
I set in schedule of every mt to restart at 2.30 every 3days.
After upgrading to 3.25 devices started to lose configuration
on this planned reboots.
I sent supout.rif to support
Hello!
I am sorry to inform you Normis, but I can confirm what ema told you! The RouterBoards with ROS 3.25 are - sometimes - losing configurations after reboots, or power failures.
I upgraded 5 RBs when ROS3.25 was released> RB133C (previous ROS: 3.13), RB532(previous ROS: 3.24), RB333(previous ROS: 3.15) and two RB600s (both were running ROS3.22)
The first three (133C, 532 and 333) lost their wireless cards configurations immediately after the 3.25 upgrade’s reboot cycle. They were reset to their defaults, grayed out, and with default names (wlan1,… etc.) The 532 was acting as a small router for a company and it lost its pppoe client settings too. The pppoe-out1 interface simply vanished!
The RB600s are doing just fine. As I stopped the upgrade for other RBs, I can not say whether other RB600s are experiencing the same problems, or not. Maybe I was just lucky with these two… 
I have never experienced a behavior like this with previous ROS releases! Every RB with ROS 3.24 is running fine, and never lost any settings!
I had the same problem with another ROS version. When I just included the system.npk package then rebooted, no other package got upgraded. But when i FTP’d every .npk file of the new system; then rebooted, all the old packages got upgraded and all my settings were in-tact (as far as I could tell). So I think if you just match current packages with newer ones when you FTP, I think that might work.
Let me know if this helps,
i have too this problem over 100 cpe ten have lost config

We have had the same issue on two of our routers as well. 1 411AH and an X86 router. It happened a day after upgrading to 3.25.
On the 411AH it disabled the discovery protocol on all the interfaces and the IP address detached itself from the interface it was assigned to. Good thing that it was accessible through the serial port.
On the X86 router, we lost our user-manager configuration.
We have a total of 6 routers that we upgraded to 3.25. All of these routers are brand new and not in service as of yet. We are going to create supouts on these routers and downgrade to 3.22 and wait for more feed back.
I just did an upgrade from 3.24 to 3.25 using my above mentioned post and everything went flawless. I even added a second drive and was able to copy the user-manager settings from the main drive to the second drive. It’s not enough to just copy system.npk over. You have to copy every single .npk package over that you want upgraded. The packages that are not copied over will not show up because all packages have to be the same version (except dude).
Hope this makes sense,
This is exactly what we did and after 24 hours the user-manager settings got wiped and went to default and on the RB411AH, the IP address got disconnected from the interface as well as all discovery interfaces getting turned off.
I had this problem
After upgrade wireless and ppp set to default settings.
wireless was disabled, ppp client was removed
Strange… I’m using x86 if that helps (probably not though). All the settings should just be stored as settings, read in each time router boots up I’d think, unless a package specifically resets certain settings when it installs. Maybe a difference btw x86 and routerboard packages?
Mine was a routerboard 133
i have other 433 and 133, and 411 that have lost configuration, please resolve this issue, in two days we have go to twentytree customers and two ap for reconfigure hardware
this problem occur over reboot or only over upgrade ? I not know if is better downgrade OS or if i can left 3.25.
I kown only that is better NOT INSTALL 3.25 and i think that 3.25 MUST BE REMOVED to download area

I have also mensioned problem with 3.25 verison, I have upgraded about 50 routers to newest version (3.25), the upgrade was successful, but what happened after that was a disaster. After storms with power failures about 5 RouterBoards have their wireless configuration in default and alse their simple queue was corrupted ! During another week about next 5 routers were in the same situatian and it was very disgusting to go to each one and configure it !
Please fix the problem and REMOVE version from stable release list !!!
Thank you for your help and let everyone consider this post like a warning agains upgrading to 3.25.

Same with me, upgrade went fine but after hard power cycle lost wireless and ppp config
i found this problem also but this is what i found
i upgraded from 3.17 to 3.25
upgraded over 30 boards then rebooted them
no problems at all with 3.25
but 2 days later i did
/system routerboard upgrade
/system reboot
then out of the 30 boards 25 lost configeration
after this i went to my boards and looked to see what was the problem and for some reason it didnt see ether1 all my settings that were set on ether1 were unknow
after system reset config all was fine
so i think its a small bug that need to get fixed up as i would not like to do a system reset on 290 routerboards
Please, anyone who is able to reproduce the problem or at least send us support output file from the previous version, which was upgraded to 3.25 (which packages were used for upgrade ?) and configuration was lost.
Typical AP/station/anything is not enough, we need the exact configuration, which was used on router before.
Send support output file or export file (rsc) to support@mikrotik.com
Thank you for the cooperation.
xezen it would be nice to have some precise information about this problem in form of:
what routerboard type,
what RouterBOOT version before upgrade
what Routeros version before upgrade
what corresponding version after upgrade
