I was in the middle of chaging my EAP network and i accidentally saved
IP:192.168.89.3
Gateway: 192.168.88.1
The EAP is on a very high roof, there is some way to temporary allow this to work so i can log in and change it?
If connecting from same L2 network(switched ethernet) and you did not disable the functionality, then you could connect using Winbox via MAC.
If you still have access to some other device which is in the same L2 segment where the EAP’s interface is connected, you can add 192.168.89.x with the same mask like the EAP has to the interface through which the EAP is available, and you can add an action=src-nat rule to that device so that you could connect to the EAP through it:
/ip firewall nat add action=src-nat dst-address=192.168.89.3 to-addresseses=192.168.89.x
Or, if that device is a Mikrotik one, you are not afraid of command line, and you haven’t disabled mac-telnet, you can mac-telnet from that device to the EAP.
For future, make yourself acquainted with Safe Mode.
