Dizzle, I actually went through the entire transcript. I am no expert myself, but could not figure out what exactly is the problem that you are trying to solve. The model number of the modem could have been useful…the reason I say that is because some of the modems run their own dhcp server while others require you to use your own $15 D-link/linksys boxes. You go from providing information that is not really useful (e.g. cat5) to providing your own diagnosis (from LAN issues to network settings on your PC) and finally to the location of the support staff!!!! Really, what does the location of the support staff have anything to do with the problem you are trying to resolve?
I have had issues with Time Warner too… and I know the staff I had the misfortune to interact with are right here in our beautiful San Diego. For the loss of productivity they caused me, I really, really wish they lose their jobs.
