C7100 V | Voice Choppines, Quality issues
Used this device to switch over my phone service to Comcast from Vonage. I have always had Comcast cable internet (Blast+) and never had any quality issues with Vonage. Ever since the switch ove...

The firmware was released by comcast today you may want to do a reboot on the modem by unplugging the power and powering back on so the modem will download the new firmware.

I'm also facing similar issues and I was hoping that I can use QOS and prioritize my Vonage device.. but they don't have this feature enabled on this router.

Just to clarify, my issue isn't with Vonage, but with Comcast Voice. Vonage did not experience this issue on my old modem. Trying to find a solution fo rthe built in voice function of the C7100V.

I am having the exact problem with this Modem/Router and Comcast VOIP. Apparently there is a Firmware issue when the router tries to simultaneously connect multiple ethernet ports AND the phone jack. Unplug all cables but the phone line reset modem and see if the issue is resolved. If so, proves this theory.

I was ready to drop Comcast over this issue....when I discovered Comcast was not the problem..the problem is with the modem/router. Comcast checked all wiring, then installed a separate voice only modem, and shazam, everything was fine. The 7100v apparently has some conflict with voice and other operations. Netgear said they wanted to work with me on the problem...I provided all my contact informaiton, and never heard from them. I am stil lusing a separare voice only modem for calls....my 7100V is now a very expensive wireless router

I am running into the same issues. Comcast came 3 times and didn't find any issue on their side. Netgear support sent a replacement modem but it still has the same issue. If you reboot, voice quality is good for couple of hours and it again goes bad. Not sure what i do ? How i receive the dev firmware since issue seems to be with netgear unit. Can i still return it ? Really frustated.
