Hi Bruce, Blue knows what he is talking about and I understand your frustration with the router. I installed the same router for my brother about 3 months ago and had some problems as well. My main problem was me trying to hard I think. I tried to do everything that the CD told me to do, but before using the CD. If you just put the CD in the computer that was working on the Internet and follow the instructions exactly, it should work unless it is broken.
Another thing is that there are ports marked on the back in very small hard to read spots. Internet is WAN and WAN is Internet, it stand for Wide Area Network, which the Internet truely is. I have also seen some routers that use port 1 as WAN alternative, so it may be best to connect your computer to port 4 just to be on safe side.
When I did this, I had a hard time getting the Internet even though it gave me an IP. The only way I was able to resolve it was to completely turn off all power to all machines for about a minute. If you have noticed, network cards in computers remain lit with the power switch off. This is so they can be wakened by remote access, this power sometimes maintains an address even though windows might think it is wiped. If you completely unplug everything for about a minute. It will truely give you a new IP when setup correctly. Just my 2 cents worth.
