4 series routers died 3 days after upgrade

RouterOS General

Hi all,

Last Wednesday I upgraded all routers to 4.2. Some were as old as 3.26. This is weird: 3 (of around 10) routerboard 433s died on Saturday (last night) - all around the same time. Due to to the position of the routerboards I haven’t fixed them all yet - but I did have that on one 411 which was also upgraded it had lost its wireless settings (just as if a new card had been installed).

Has this happened to other people?

thanks,

D

I don’t see any problems with a bunch of routers I upgraded to the new version. I always upgrade the bootloader too, before ROS update and after ROS update (if a new version is available).

I upload only the packages that are used.

I make sure the downloaded npk files are complete, not corrupted.

I login into the router some time after the upgrade to have a quick look around, I look at the logs too…


All fine since more than a couple of months even with the 4 beta version …

Good luck to all :wink:

Ahahahahaaa mate mate did you update the license BEFORE you restarted the routerBOARDs ? :slight_smile: if not - thats why they went offline - you have 72 hours to use the WInBox function UPDATE LICENSE to the new v4 license :slight_smile:

:frowning: Oh no… this is very sad.

What is the procedure to fix this problem - I know what I’ll be doing all day tomorrow…

thanks for the info

Hi NetworkPro,

I didn’t use Winbox (I’m remote and only have telnet/ssh access) - I wasn’t sure about the “update license” WinBox button thing.

Do you have a link to any docs on what to do to get a “dead” MT board working again (even if I have to get to the boards and reset them, etc).

thanks,

D

I havent seen what happens to a RouterBOARD in this situation. Maybe a cold reboot will wake them up for another 72 hours? If not - you will probably have to reinstall them … ask support@mikrotik.com of course.

Hi NetworkPro,

A cold reboot didn’t do anything so far (no contact with Winbox) - funny though one did appear to stay alive long enough for one guy to get an IP address via an ethernet cable but he couldn’t get in. I’ll pull one down and try to hard-reset it tomorrow and see what happens…
