Whats the difference between Road Runner cable service vs. ADSL?
The main difference is the bandwidth (techy stuff about how everyone is hooked up) is not shared with ADSL whereas with cable, it is. The end result is, with cable, as more people get the service, your speed gradually slows down according to the number of people on the service. As far as the real world differences, the only way to measure is to use a download bandwidth test on each service at the same time and measure the results. Road Runner has had some bandwidth problems, but so far, has been able to correct the problems and is about 3 times faster than ADSL!
