I'm upgrading to wireless broadband soon because i'm getting a laptop. I'll be using a livebox, do I really need to buy a wireless adaptor for my home computer, which at the moment isn't wireless enabled. Thanks. Heather.
Depends if you want to use it wirelessly. If you don't you can continue to connect by ethernet cable.
That is the very best set up, in my opinion. A laptop for portability - use it in the garden, and a hard wired desktop for the added security when online banking and so on.
