It's actually a c7000v2. But the upstream light won't stop blinking no matter what I do, and it's been like this for 4 days. I e tried resetting it in every way possible, even a factory reset. I've already talked to Xfinity and they say the signal os good, and the problem is with the hardware. It's less than 6 months old. The 1st screenshot is with it solid, and the second is flashing

STILL having the same problems, and all Netgear and Xfinity want to do is point fingers and pass me back and forth. I've been reading ALOT of threads in here about the ridiculous amount of problems with this c7000v2, and I can't figure out how they're still being allowed to still sell it. There should have already been a class action lawsuit filed no later than 2018. I bought it from Best Buy for $189.99 back in December, and already had to pay $17 to have Netgear replace it once. Now i'm about to insist on a full refund, because I haven't had a solid week yet without numerous issues that make my internet service nonexistent. I've had my upstream light flashing with only 4 locked channels for about 5 months now, and can't get support from either side no matter what I do. It will have a "UNICAST DSID PSN startup error" every time as soon as it boots up after saying "Honoring MDD; IP Provisioning Mode = IPv6" in the event logs. Now it only shows "honorMdd(4)" in the IP Provisioning Mode. There will be legal repercussions if nothing gets done about it by the end of the month. I'm sick of dealing with it, because i'm spending on average around 3 hours per day on the phone and in online chats with support from Xfinity and Netgear. All of my Power and SNR levels are within range, all 24 downstreams are locked, so I don't know what else to do but demand a refund and get as far away from Netgear products as I possibly can

If two different units have failed, then either this is a ISP line problem and the ISP needs to send someone out to check the signal at your place, or you have two faulty units. Have the ISP check the signal and line quality UP to the modem. Be sure there are no coax cable line splitters in the between the modem and ISP service box. Be sure your using good quality RG6 coax cable up to the modem.Disable IPv6 option on the modems web page. If anything find a stand alone mode and conenct a external router and see how that does, if it works better, the the problem is the C series modem. Good Luck.

I’m curious if you ever got this resolved. I’m running into the same issue where I’ve had xfinity out and the signal is good. My Netgear C7000.v2 will work for 30 minutes then lose the signal for 10-15 minutes having the upstream blink or internet light blink. I contacted NG multiple times this week confirming that my isp is set appropriately and that my hardware is the Most up to date. I have been on the phone with both Netgear and xfinity all week and just want this issue resolved. It seems to be a consistent issue with the modem. Any suggestions or advice on how you had this resolved would be appreciated/ were you able to get a refund ?

This problem was driving me crazy and I finally found that the isp cable going to my modem wasn't fully secure. I had to really press it into the the metal sheath and clamp it down so it would stay in place.

HiCan you please confirm that your issue is resolved like you said. I am having the same issue with my "like new" C7000v2. I did reconnect the cable in to the cable connector behind the modem several times. When I boot the modem router the upstream light is solid green for about 10-12 minutes and it starts steadily blinking again forever. According to the manual blinking green means "The unit is scanning for an upstream channel." (page 10) The wired and wireless connections both seem to work fine and upon checking the netgear genie GUI to the modem router for the "Upstream Bonded Channels" I see that 4 channels are locked and 4 are not.This seems like a common problem on these devices.

  Other than the blinking, is it causing an issue?

    Yep. Wifi says "connected without internet" and my Xbox won't connect to Xbox Live. Here's a screenshot from today
