Has the modem been activated?
First of all forget the cd
There should be a little reset button on the rear of the router press and hold that for 30 seconds and release. turn off modem router and pc. Switch on modem and allow to settle turn on router and allow to settle turn on pc . Do you have a new connection now? If so good good
If all working open web browser and type in 192.168.1.1 and enter the router pages open and request user and password admin admin.
Set up a wireless key selecting WPA2 personal as your type and TKIP/AES and use a password.
Goto admin section and change router password.
In your first post you say virgin router I take it you mean modem and you were not supplied with the netgear router as well as a modem?
If none of this works and you feel upto it we could try a custom firmware on one of the routers
