I learned a long time ago that it just is not worth the "rental" of their modem/router. We replaced 4 within three months. Most of them are refurbished junk and unreliable. It is best for you to go to Best Buy or wherever you purchase reliable electronics and get a good quality modem/router. Believe me, it has been the best move we ever made. The only problem now is Comcast internet has been having outages the past few days...
