Hi Craig, it depends on your setup. Do you have Vodafone TV or SKY? And is your connection a Cable connection (ex-TelstraClear)?
For example, depending on your situation, you could get someone to install internal wiring in your house to link an Ethernet connection from your modem to required location on the 2nd floor. Unfortunately this is something you'll have to investigate with an electrician or specialist network installer as it isn't a service we're able to offer. would be great if you could give us a little more info to go on so we can give you better advice.
