Can connecting another computer to my network influence the connections of the other computers?

Rick R: Can connecting another computer to my network influence the connections of the other computers?
I had two computers both connected to a wireless router. Yesterday I connected a third computer to the network and, although the connection goes through for this new computer, one of the original computers now says “Limited or no connectivity” and cannot connect to the Internet. Is it possible that the new computer is using up too much bandwidth and is therefore preventing the other computer from accessing the Internet?

Sounds like you have an IP address conflict, I would check the addresses on the computers to make sure these are no duplicates host IPs.
