Ok my service provider in Hawaii is TIME WARNER. We have cable service (road runner) and it comes with a free surfboard modem. Latley I noticed the local stores selling cable modems etc and was curious...... Are they any advantages to owning your own cable modem? Are all cable modems the same ? Do you get better speeds or connections by buying a certain brand? Basiclly should if i buy a cable modem is it any better then sticking with the free one?
