the modem be smaller than other which be a benefit to I . the modem work with Time warner cable and it set up quickly - can not say the same for time warner . this be important information about set up the modem with you cable company : I have 7 hour worth of call try to set up this modem because hold time be about 30 minute between reps. they will tell you that this be `` not '' a approve device even though it be approve on time warner website and level one tech support . Hang up on the rep who will not set up you modem and call you local office - finally , I do get through to someone who do not even ask for model number and all they want be the MAC and serial number - here be the problem , my device address end with a `` b '' and the rep apparently could not assign a b to the system and take it upon herself to enter a `` 8 '' and never tell I about she change . so , a phone call to tech support and then back to customer service to change a 8 to a b - then back to tech support - it be work perfectly . tip : be certain to tell they you be use a DOCSIS 3.0 modem , that way the `` b '' will be accept . and then ask they to repeat the MAC address and DOCSIS version prior to end the call . you will save about 5-6 hour in phone call . additionally ; I do have digital voice and Tech support on `` that day '' say that none of the telephony modem work with Time Warner . they have ask I to pick up a free splitter and two short coaxial cable from the local time warner office so that I can connect both device . once both device be connect , time warner say they would not charge a monthly fee for a deactivate modem be use for phone call only .
