Broadband Cable delivery be change up in delivery speed . for example ; Comcast Xfinity be go up to 15 + mbp . if you be experience a lack of speed , some website take longer to load and movie delivery problem , it may not be enough to `` reset '' you older modem . I be not a `` techy '' so when I experience slowness and could no longer completely watch my instant play movie , I wonder what the problem could be since my broadband have work fine a year ago . we also use wireless networking in we home and there be all kind of complaint , especially from my college student son . I think I must be like many out there ; I do not take the time to read the pamphlet deliver to I when I go online . when I do that , I realize it be the modem speed that be cause most all of my problem . the top-of-the-line recommendation for my service be the Motorola sb6121 3.0 cable modem ; and here at Amazon you can get the non-retail package deliver to you door for about $ 15 less than you can purchase it retail at Walmart . I feel like I just get rid of my 2003 auto for a Lambo . it be a great convenience .
