Wireless connects, but no internet access

I have a new installation on a new Dell laptop (i7 8GB RAM). I find my network and successfully connect to it, but then when I open a browser, it acts like I don't have an internet connection. Please help.

I always find with network issues you want to try pinging in one order or the other:

ping localhost

    ping 127.0.0.1

ping you local gateway (normally 192.168.0.1)

    ping 192.168.X.X

ping an IP external to your local netowrk (Google public DNS)

    ping 8.8.8.8

ping a domain to see if you can resolve a domain

    ping google.com

depending on which of these work it will help you track down the problem, if you can't ping your router your network isn't up as advised, if you can ping further then you know you're looking in the wrong place.
