Unfortunately the reset switch on the cyberoam does not work as you would expect it to, i.e. it does not reset the router to factory defaults. Maybe it should be labelled “Do nothing” instead of reset.
In order to reset connect the router by serial cable to a computer. You will need to have a terminal program
You can download the old Hyperterm program as a trial from http://www.hilgraeve.com/hyperterminal/
or use Putty –
