(1) Away from home - you want to connect with your home router and internet account? Or (2) In the home, in another room, you want to connect with your home router and internet account?
yes i want to use it away from home
The only way you could do that was to connect - over the internet - with your home system. And you'd already be connected to the internet - so? What's the reason for wanting to connect via your home account when you're away from home?
As das_stig mentioned, there is only two ways to connect to the internet when away from home:
1) Contact a cell provider, and get one of their USB dongles 2) Do what a lot of us do: Go into a place that offers wifi, and use their wifi. It might cost you $5 or so(depending on the place, but some require you to purchase something), but it's worth the price if you really need to go online away from home.
