Boss' laptop not working with her home Tiscali router

[MarcLister]

What up, clever chaps. My boss has a Dell laptop that she uses at home to dial-in to her work computer so she can work from home. She's been having trouble getting the wireless (I think the wireless) to work with the Tiscali router she and her husband have got.

Her husband is fairly decent with IT but he's not been able to solve the issue and she's asked me to look into it. I'm going to ring Dell on Monday morning to see if they've got any ideas or have heard of other Dell laptop users experiencing the same things with Tiscali.

I was wondering if anyone here has had the same problem or has had to fix it for someone else and knows what I could do to get things working again.

I've got her husband to check the network connections and proxy settings and they're OK so without ringing Dell or getting new information I'm at a loss. Any help or suggestions would be most useful.
