hi everyone;
I am facing aproblem in RB133c and i reset it by the jumbers on the board. Now i can't access it and i don't knew its MAC address neither its serial numbr or the IP address plz i am looking for a help, any one can help me.

Connect directly your pc nic to the ether of the rb133c and use winbox to access via mac address, this can be done using the button with three dots on the right side of the address box.
Another method is to connect via serial port 8n1,
Default user is allways admin, and no password.

hope this help.

I connected it directly through my ethernet NIC but nothing happen. Sometimes i try to connect to the RB133c through the old IP i assigned to it before resetting -which is 192.168.1.250_ it gives me ""could not connect to 192.168.1.250(port 80) -no response""

Try to use the neighbor viewer, this little program will show you the mac address of the rb.
