How to access Mikrotik router

Hello, all

i remove the default configuration after i can’t access it again with MAC also,
So pls, tell me how to do. pls

I am not sure if this would be a simple thing to do and I am afraid that you have to go to an expert and spend some money in order to get rid of the problem.

Few things you can try:

Look at the bottom of your RB, you should see its MAC. type the MAC manually in winbox and try to connect.
Clear the config using the reset button, follow this: http://wiki.mikrotik.com/wiki/Manual:Password_reset

What is the model of Routerboard ?

Set off the firewal on your pc and try again
