will not fault TWC or the modem in this review , but TWC in my area be unable to accept this modem for support . I have instead order the Motorola SBG6580 DOCSIS 3.0 Wireless Cable Modem from Amazon , which TWC can accept . just put this out there for those in a similar situation . I intend to use the 6580 with a Cisco Linksys e4200 and will review that setup later .
