Orange Livebox

I am interested to know if anyone has had the same problem as I am encountering with my Livebox, I have a desktop working on Vista which works perfectly with the Livebox but I have bought a laptop which is working on Windows 7 and although it shows that connections are available with the livebox I cannot get it to connect. I have taken it to a friends house who uses a Neufbox and it connected straightaway. Would be grateful for any feedback or suggestions.

Thanks for that will repost as suggested.

Can't tell you why this might be happening but both my son and grandson connected their Windows 7 laptops to my Livebox with no problem. But I am running Windows 7 on my desktop so maybe there's a problem twixt Vista and 7? Might be an idea to repost this on Computer Corner, the home of SFN's resident computer gurus!
