Prior to buying this Motorola Surfboard modem , I owned the same Motorola Surfboard but it was a 2.0 - I had owned that one about 4 years and it was very reliable . Within the past 6 months , I noticed that I kept losing my internet connection and when I went to troubleshoot , there was always a modem connectivity issue . I called my cable provider ( Comcast ) and they checked and told me that my old Motorola was at " end of life " . The Comcast technician recommended this newer 3.0 Surfboard model and assured me my connectivity issues would cease and that my connection speed would be much faster . I was a bit skeptical but I decided to take a chance at ordered this model . It was a little pricier than I thought but so far, the technician proved to be absolutely spot on . My computer connects so much faster than it did the the older model and I have not " dropped " a connection since buying this unit . It was super easy to hook up and I just made a call to Comcast to ascertain that everything was good to go - very simple . I hope to get at least 4 years of service from it like I did the prior model - it is much smarter to buy this Motorola surfboard rather than renting from the cable company - this will pay for itself in about a year so the purchase price will be worth it in the long run .
