Comcast/Xfinity was onsite 3 separate visits to check the Brand new cable connection to my home. Comcast just completed a 1 million dollar project to have cable ran to my rural neighborhood.  This persistence from Netgear to blame Comcast cost me $40 for home service visit. The replacement modem from Comcast until I reconnect the Netgear has worked flawlessly!!  

I just received the replacement from Netgear and will work on reinstalling by end of day hopefully the THIRD modem works??

        Modem issue still exist! Netgear and Comcast fighting it out who's fault it is.

        But this modem gateway will not work!!

        Comcast installed their own modem weeks ago and it works perfectly.

        I reinstalled the C7100V and it crashes within 15 minutes!!
