Cam has an Arris Wi-Fi router hardwired into his computer, but he can't modify the settings. Leo says he should be able to. He should call the cable company and ask them for the password to access the router. Or, instead of using their router, ask them what third party routers they will support and he can buy his own. He'll want a DOCSIS III.
Check out this app: Snoop Snitch in the Google Play store. It will tell him how secure his router is.
