Im having serious issues with MT on routerboards.
I updated a RB 112 if im not mistaken to v3 works fine for while then locked me out.
I discovered it actually just became extremely slow.
So eventually i went on site and downgraded to 2.9.45.
All working untill i enabled NTP client. Now unusable again.
Other Boards Connect then d/c the whole time on v3 & one just dissappeared.
This happenned to all routerboards i updated.
O & winbox doesnt work, have to ssh in & get following error.
could not connect to console, try rebooting the router
Connection to 192.168.12.9 closed.
Also just managed to get in via winbox for short period of time on rb112 only to see it actually didnt even enable the NTP Client.
Then dreaded “Router Disconnected” again.
Looking back this topic is VERY ambiguous!
Also turns out it was simply the weak boards back then, don’t have issues like this anymore…
