Yes I can add a wireless router, but I prefer to solve the wired connection problem first, because I want to see if this is an isolated issue or is 7 prone to this kind of thing. This is a customers computer, and I anticipate the possibility that I will encounter this again. I want to try to figure out why I am only given the choice of a ppoe type of connection that needs a username and password. Roadrunner and FIOS provide always on connections. If anyone has any knowledge on the subject, I would be grateful, but please no newbie suggestions like "have you tried a different ethernet cable?", etc.
