Hi Philips Series 1 - 320gb Seagate Turbonet card - V3 1.6.2 Image - Sky tv source

I have got around again to install my tivo ++++ fingers crossed. Upon the setup guide it says line unavailable. I guess this is a firewall issue... The ethernet is plugged into a switch and this plugged into a router. I am on Slingshot. Any ideas on this as I am out of them.
