Hi Robert, Do you see your router's listing for a WiFi connection, if you are trying a wireless connection. Have you used the right password? Is the password entered right "Upper and or Lower case letters".
What do you get if you connect direct to the router with a nic cable?
Is this a Windows machine? What do you see when you enter 192.168.1.1 in your web broswer?
What about under your networks listing. In Windows, this would be, click Start, Computer, the the Network entry on the left column.
