Connecting to the internet is a two step process. First you need to connect to your wireless network (basically radio waves) and authentication to the wireless router. Once that is complete, you then need an IP address and a "gateway" (that's the router part of the wireless router) to get to the internet.
You'll need to first verify connection to the wireless network. You can do this by opening "Network and Sharing Center". You can then check for 'active networks' and clicking on the name of your network (should be on the right of the panel). This will then show status. Report back with signal quality, speed, whether IPv4 or IPv6 shows as "Internet" or "No network access".
Finally, click on Windows Start, type characters RUN and press Enter. In the box where it says "Open:" type CMD
When that window opens, type IPCONFIG /ALL and let us know those results.
