After looking through the posts in the fourm and writing my question, I glanced down and saw that the answer was sitting 5 posts below mine.
Last week I was playing around with my wireless connection, trying to get something new to work (always results in problems) and I can no longer get my wired (ethernet) connection to work. The wireless works fine (from same router). When I plug the ethernet into the computer, the system connects to it, but I can't access it with any internet program (explorer, firefox, etc.). I've tried pluging my computer into other tried and true connections with no luck. I'm not sure what specifications would be usefull, so let me know and I'd love to provide what I can. Thanks.
