I just ordered a Bellsouth DSL. I did so on the internet. Rather than pay $100 to have it "professionally" installed Bellsouth indicated that I could do so myself. I know nothing about where or how to install a DSL modem. I opted for the usb hookup rather than the port which looked like something my machine does not have. I have a Dell 4400. I would greatly appreciate any advise anyone could give...........Thanks
