First you need to determine if the problem is with the wireless network adapter in the computer or with the wireless router.  Do you have any other computers on the network that have also lost their connection?  If you go to a free wireless hot spot, can you connect there?  If you post a reply, please include the model of your computer, model of the wireless card, and version of Windows.

Without the ability to test the network card on another network or test the router with another computer, it is going to be very difficult to decide which device is causing the problem.  Does the wireless adapter show up in Device Manager?  In Network Connections, is the wireless connection icon present?

In network connections there are 2 icons.  One is "1394 Connection Net Adapter", the other is "Local Area Connection Broadcom 440x 10/100 Integrated Controller".  Both say enabled.  How do I get to device manager? 

It looks like your ethernet adapter (Broadcom Integrated Controller) is properly install, but if there is no wireless connection listed there, then it looks like the wireless adapter is not installed or is imporperly configured.  To get into Device Manager, go to Start > Control Panel > Perfomance and Maintenance > System, click on the Hardware tab, then on the Device Manager button.   Expand the list by clicking on the + sign next to network adapters.   See if your wireless network adapter is listed or shows as a problem device.  If it is not listed or is showing as a problem device, then you need to install the drivers for the wireless network adapter.

I appreciate your help.  I feel like I'm finally getting somewhere with this.  The wireless-G notebook adapter is listed under device manager and when I click on it , it says the device is working properly.
