    I bought this motorola sb 6121 as a replacement for a broken motorola router. Item was in stock at local best buy bought online picked up with in an hour .Out of the box very easy install,they are very similar i think in my experience anyway.contacted service provider and connected in minutes.Very pleased with my replacement .there are many options on routers but this fit the bill.I can connect in my garage that is detached so it works for me.pleased with my router so far,if it last as long as my old one i will buy another one.No problems so far with this router.My older one would loose connection about every three days and have to repair my connection.

    Got this modem after our modem rentel fee went up to ten dollars a month. Contacted comcast after getting home to get the modem activated and after about a 10 minute call, was able to browse the web. Well worth the investment as this will pay for its self in about less than a year.
