RB532A - Loosing interfaces after upgrade to 3.14 and FW2.17

RouterOS General
1

Hello.

I don’t know if someone expirience that problem. I’ve recently upgraded some of RB532A and after upgrade some (about 50%) of systems show only one ethernet insteed of 3.

[admin@XXX] > interface ethernet print 
Flags: X - disabled, R - running, S - slave 
 #    NAME                                   MTU   MAC-ADDRESS       ARP       
 0 R  ether1                                 1500  00:0C:42:0A:70:65 enabled   
[admin@XXX] > system routerboard print 
       routerboard: yes
             model: "532A"
     serial-number: "12A201D728D2"
  current-firmware: "2.17"
  upgrade-firmware: "2.17"

I don’t know how to solve the problem permamently. But I’ve experimented on one of thous routerboards. And I see that when I downgrade system (2.9.51), downgrade firmware (2.12), and upgrade system bac to (3.14) is OK.

So does someone had the same problem? Maybe i’m doing somethig wrong?

Gr8 :frowning:

So correct me if I’m wrong. Only way to bring back interfaces is to downgrade, or wait for new version of RouterOS/firmware?

Or maybe someone knows other less invasive than downgrade or faster than waiting ways?

only downgrade firmware not OS - you can find it on routerboard.com
