I have the DNS servers set in the pc itself. These are for OpenDNS. Yours should probably be the Rogers DNS address. Can you run that command and see what is currently set in the pc. Normally the modem or router supplies the DNS server address to the pc, laptop, gaming device, etc, etc. It can be set in the modem, or in the end device. If that DNS entry is left empty in the modem or router, the modem or router will use the ISP default DNS server.
