I buy this cable modem because I do not want to waste money rent one anymore from my cable provider . this be a no-brainer to install . my son-in-law buy the same Motorola SB6121 DOCSIS 3.0 Cable Modem and be thoroughly satisfied . I have use this for approx . a month and I never have to reset it . I be always reset the rental modem . thank you Motorola for make another excellent product . I also like order this product from Amazon . com . it do not get any easier and delivery be great .
