When it is connected does your computer see it at all? What lights are showing on it, and which ones are flashing?
The computer recognizes it. The light on the back of the computer that shows internet connection lights up. On the front of the router, the Power, Wireless-B, and Ethernet lights are on, as is the Internet. That's when everything is plugged in as it usually is - the blue cord connected to the router connected to the back of the computer, and the grey cord hooked up to the modem connected to the router (the grey would be the ethernet cable). Now I have the ethernet cable plugged right into the computer. As for WPA/WEP, I haven't a clue.
