I have one thing to ask; did you first hook up your camera wired, directly to the router, first? This will make the wireless set up much easier. Once you have the camera hard wired to the router, you will get it's IP address.
Once you know the info above, you can follow the procedures in your equipment manual to set it up wirellessly. You also need to know your "house system" IP address. Type "what is my IP address" into your computer brouser. This will show your home IP.
You will need this; ie 282.122.2.75 (I chose these numbers randomly) to give you the idea. When you forward the port, you will need the home IP 282.122.2.75 followed by the port number you assign, ie. 282.122.2.75:93 , where 93 is the port number. 93 is only the example I use, you can select your own number. Contact Bill at X-10 to help you with the port forwarding. He has helped me. He is very good at what he does.
