HI,
I have a RB 750G
I don't understand, i put 4.5 version
an now it's impossible to connect with winbox

what'is the solution

I just tried 4.5 on a 750G and have had no problems. WinBox works just fine.

I assume your other means of connecting work fine. Is this so?

Have you double-checked that you can 1) ping the 750G in question (that is, it is reachable on your network by the host on which you wish to run WinBox); and 2) you have winbox enabled in "/ip services"; and 3) there are no filter/firewall rules blocking you?

Aaron out.

hi
thanks for your message

1 ) I made several reset with reset button
2) normally after a reset, I should have the original configuration mikrotik
3) original configuration is : 1 port : wan client dhcp, 2-5 server dhcp (192.168.88.1)

so, on any ports, I do not get ip address

4) if I put a fixed IP address on my pc, ping said : hostname : Unavailable
Response Msg : Request timed out
But, when I'm connected to the port, the LED lights

sorry for my english
