Hi,
does someone else has the same problems as we did after update to 3.12?
Two good running, complete different systems, in different environments 1000´s of kilometers from each other!
- RouterOs 3.11 on x86
- RouterOs 2.9.51 on x86
did the same (nothing!) after updating to 3.12.
No possibility to reach the sytem either by ethernet (different ports!) or wireless.
Not even by a connectet terminal.
After reboot you see the welkom screen with login but you can´t enter anything.
I hope there will be an answer soon!!
There is also a Post in RouterOs forum (v3.12 crashing on x86) !!
I had better read before
