I just upgraded to RouterOS 2.9.43 and Winbox immediately stopped working. It loads and looks OK, but most of the windows (for example IP → Hotspot → Active) contain no data. If I open a terminal from within Winbox I get an empty terminal window.
However, if I change to using TCP/IP to connect to the router it works.
Has there been some change in 2.9.43 that stops MAC access to Winbox working?
mac is very unstable connection as tcp/ip take care of packet retransmissions end everything (ethernet), and if you use this in secure mode, then even more unstable it becomes.
it is advised to use mac-winbox only if there is no other choice left and you have to connect to device (like there is no IP address present)
