[Nottingham] Wireless Broadband

[Sarah Swindell]

Hi,
My neighbour, two terraced houses away, has offered to share her Broadband 
connection with me.
I'm planning to buy a wireless router but don't know if it'll work as she 
uses WinXP (I'm working on getting her to consider linux). I use Mepis and 
Ubuntu.
Any idea if I will have problems if the connection is shared over linux and 
another OS?
Can anyone recommend a router which will reach next door but one but not 
share it's signal with the whole of Sneinton?
Thanks in advance,
Sarah
