new network adapter

ok so i need a new network adapter for my pc as i dont have a hard connection to the internet.

i have a decent broadband connection so need a wireless adapter that makes the most of it, so im thinking of ignoring any usb adapters and want to get a dedicated network card.

i was looking at some asus models as they seem decent at a reasonable price, but do you guys have any recommendations or any bad experiences or anything like that?

again price isnt much of an issue but i want something that will last. at the moment ive got a 20mb broadband connection.

so any thoughts?

i live in the UK by the way.

Basically anything with a 54mbits or higher transfer rate will do.

I'm more worried with how much interference you have between your router and receiver.
