UK provider of home internet 'hotzone'?

[1lit]

I live in London. Anybody know of a way of being able to connect to the internet from anywhere around my apartment? Would be great if I could move my laptop anywhere without cables and still be online. How would it all be setup/likely cost?

Thanks.

you need a wireless ADSL router / modem (around £120 for a router?) and a reciever card for your laptop (£40)

just did a quick google search : http://www.dsl-warehouse.co.uk/ - not sure how good they are...
