How does it compare to cable modems?
Cable has some inherent drawbacks. First, the cable network is shared, which means as the number of cable users increases the speed on each individual°s line decreases. Second, a shared network is less secure than a dedicated service like DSL, as neighboring cable customer can more easily intercept data or hack into another user’s computer. Third, the upstream speed on a cable modems generally no higher than 256 Kbps.
