Thanks for the information - BT don't seem to go to this level on their website. I prefer to know how I'm actually going to set something up before buying. It's amazing the range of different requirements that people have. I choose not to use wi-fi because I simply don't trust it and prefer not to have extra microwaves/radiation or whatever floating around the house. It's bad enough with mobile phones and microwave ovens (which I almost never use).
