well, I like the Runon format there. Very nice.
First, what OS are you using? What browser?
Under IE there is an option to use AUTO detect settings. You will need to turn that off. If you are using XP, do a repair on the active connection. Should be under the right click menu from My network places.
aside from that, are you getting an IP from the router? can you ping the router? can you ping and external site?
