Hi
I tried to setup my routerboard 411/411R in bridge mode,
but accidentally I had disable Ethernet interface by Winbox, and now I cannot enter in my router (winbox doesn’t find nothingh and I cannot ping it by ethernet interface!!)
How can I reset my router?
Time to pull out the good old console cable.
Can you please tell me if is it cross cable? (female-female)
and the connection from Hyper Terminal is ok?
thanks a lot
hi …you can connect to router by hyperterminal…or securecrt… i’ve experienced the same problem
it’s not cross cable… see this https://specialcomp.com/beagleboard/null_modem.jpg
if your pc doesn’t support db9 ports you can use db9-to-usb convertor…
ok!
can you please tell me the correct command by Hyperterminal for reactivate ethernet interface?
Thank you very much
just click on interfase , then right click on your mouse and there is a enable command, thats all..
but from Hyper Terminal can I use a mouse? are you sure?
from Hyper Terminal I think need to use command line, is it correct? and if need to use command line wich is the correct command?
Thank you
i forgot about it . 
.. do this:
interface enable
if dont remember what is the name of the interface just type :
interface print
thanks a lot!
in Hyper Terminal the configuration is:
serial
port comxx
baud rate 9600
data bits 8
parity none
stop bits 1
no dts/dsr
no rts/cts
no xon/xoff
is it correct?
thank you
Baud rate should be 115200
115.000 bauds and is ok 
the correct command I think is interface enable ether
but after I need save the new configuration or I can reboot and the new configuration is automatic saved?
thanks a lot
Yes, any changes you make to the router are instantly saved and active unless you are entering a config in safe mode. If safe mode is enabled, if you are logged out improperly from the router, it will revert the config back to what it was before you entered safe mode.
thanks a lot for your kindness
now RB works again
