unplug fon first
i found it easy to open up a cmd window
type : ping -t 192.168.1.1 it should say something about cant find host device
cant remember word for word,
then open up putty , set it for 192.168.1.1 telnet and port 9000
then plug in your fon
hit ok on putty when you see the cmd window start getting a reply from 192.168.1.1
