New laptop - problems with Linksys

Been using Linksys for my home wireless for quite some time now with no problems for 2 laptops and 1 x desktop. Just got a new laptop (newer version of a current one) and for some reason while it recognises the Linksys and when I click on "find LAN" it says connection successful but it won't allow me to access any URL?

Any advice appreiciated.

Thanks
Roy

Firewall?

Check also the security settings on the linksys, it might be doing MAC address filtering.

Many thanks for the advice, hopefully I can now get it sorted.
