VPN Router

I currently have a cisco wireless router connected to our cable modem. My wife needs to connect to her work via a cisco vpn router. Since I do not have access to this router, I do not want to connected it directly to the cable modem and then to our wireless router.

I've setup up a second wireless router just for her VPN sessions:
Modem > Cisco Wireless router > Cisco VPN router > her laptop.

My issues is that the VPN router is not connected to the internet.

Any assistance with this setup would be great. Thanks!
(please note I am an extreme nub when it comes to networking)
