Hello My friends..!
sorry if my question seems illogical but I disable my mikrotik router wifi Accidentally and I don't have access to it physically to connect to ethernet, is there is a way to re access it in this way ..?

You will be able to access it physically, through an ethernet cable. If your computer does not have an ethernet port, you will need to find a cable transition from the port that is available for your computer to RJ45 to insert the cable.Of course, there is also an option via the Internet.

How were you connected to it before you turned off WiFi?

Is it accessible through VPN?
