Phone call clarity using Netgear C7100v Cable Modem
I have a C7100v cable modem (replaced by Netgear once already). I have to reboot the modem everyday to get clear phone calls. Callers can here me fine but I can't here them clearly as their voice breaks up. I've had Comcast replace the wires from the street pole to my house, the splitter and wire connecting the cable modem. I also recently had Comcast upgrade the firmware for my cable modem and have purchase new AT&T wireless phones. None of these measures have resolved the issue. I am ready to turn in my cable modem for a refund if I can't resolve this issue soon.

I had the same issue with mine....even sent the first one back thinking there was a defect. I had comcast senior techs at my house three times....everything checked out on their end. They then installed a separate voice only modem as an experiment, and calls were crystal clear with no breakup. I continue to use the separate oice modem, since I make calls for work on this phone, and can't afford the bad quality. My 7100V is now a very expensive wireless router. Netgear has been no help.
Thank you for your reply. Can you tell me what voice modem you use and how you have it installed with your C7100v?
I am now using an Arris TM822 for voice modem. Installation: Where main cable comes into house...at splitter...a separate branch goes to the voice modem., with phone line plugged into the back of the TM822. The main cable is now split 4 ways...1 bravch to voice modem...1 to 7100V...and 2 to tv boxes. Voice now completely separate from the 7100v....which is now like I said...an expensive wireless router. I haven't had a single problem with this configuration. Just disappointing that the 7100V can't do the job it's supposed to do.
