I've just shifted house and have been trying to access the internet via my flatmate's Telecom wireless router (Thomson).  

I run XP Pro and my friend runs Vista.

My laptop connects no problem at all and that's as far as it goes - no internet, no email. I've replicated the settings from my friend's laptop to no avail.

I'd really appreciate some pointers as it must be a setting (or lack of a setting) on my laptop that is not allowing the internet connection.  Probably something really simple!

Advice/suggestions would be much appreciated.
