wireless to wireless modem?

No, you can't connect via ADSL.

You need to connect the Virgin router (there's no such thing as a wireless modem) to the Netgear via Ethernet to one of the Netgear's Ethernet ports.

But in addition, you MUST switch off the Netgear's DHCP server. While you are in the Netgear's settings: set the WiFi SSID to the SAME SSID as the Virgin box, set WPA security with a long random password and give the Netgear a new IP address so that you can "talk to it" in the future.
