security keys or MAC filtering is being used. These features are found in the router's setup pages and are used to keep Internet hitchhikers away.
My fiance got a new laptop for Christmas. Her family owns/runs a business probably 100 yards from her house. The business has a T1 internet connection and it is set up to be a wireless network. My (soon-to-be) father-in-law bought some sort of amplifier to increase the signal at their house. He also bought a router. He can get online with his laptop, but we can't get online with my fiance's new laptop.
When we click on the network icon in the bottom tray, it shows that we have "excellent" signal and we are "connected". But internet Explorer still can't load a page from any site. What else do we need to do to connect to the internet with this wireless connection?
