Pretty sure the moderator stated before most of the problem is that your using a old phone modem which isn't capable of Premier Tier upgrade. Best thing is, since the modem is Cox equipment, they should be able to provide a upgrade for free. We can't help you though if you don't respond to your own threads.

Also, if your waiting minutes for a connection, then something else is wrong other then the internet IMO. What are you waiting for exactly? The browser to open? For the home page to come up? To download something?
