I went home during lunch and I was able to get an automatic IP address, but it did not give me a gateway. I guess that is where the router would come into place?
When I connect mine to the router, it assigns a dynamic IP address for my Laptop, since my router default IP address is 192.168.1.1, usually the Laptop will be assigned an address something like:
192.168.1.120 or something for the Laptop's IP address
The Gateway address will be 192.168.1.1 since the router is the Gateway out to the broader internet. Now I don't actually have the router connected to the internet, so I don't get internet access from my Laptop when running the lighting tests.
Now I did have to log-into my Router and access the security setting to allow the Router to pass Multi-cast traffic (*Note not all Router will pass Multi-cast traffic) to get mine to work.
Another thing to check, you don't happen to have two NICs in your PC do you?
If you do, you will need to dis-able one of them and just use one of the NICs
