I had to call them repeatedly but eventually they said that there was 20% packet loss! They wound up resetting their router, also the tech came out and put me on a shorter length cable. Not sure if attenuation is a factor, but I was on about a 50' cable prior to that and after all of this, I don't have the problem anymore, so I am not sure of the fix in this case. I do know it had nothing to do with the OS. I have had zero problems with dhcp on any fedora Marc
