Re: Blinking upstream light
Other than the blinking, is it causing an issue?

Re: Blinking upstream light
You've got a few errors but nothing crazy.
Any splitters, attenuators, or amplifiers in line?

Re: Blinking upstream light
t3/t4 errors tend to be line issues.
So you know its either:
1. The isp's line
2. The cabling
3. The modem
You can always try a different modem and see if it works. If it has the same issues, then its the cable running to the modem or the isp's lines.

Re: Blinking upstream light
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.

Re: Blinking upstream light
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.

Be sure to power OFF the modem for 1 minute them back ON.
Try a different modem to see if the problem continues or not.

Re: Blinking upstream light
Hi
Can 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.

Re: Blinking upstream light
Hi,
I already talked to the ISP 2 days ago and asked them to check my connection and the agent said everything is normal. My modem is connected directly to the ISP cable; there are no splitters of any sort in between. I powered off and after several hours powered on several times in the past week and the same issue.

Re: Blinking upstream light
@milhan the ISP's first response is always "our line is fine".
I'd recommend starting your own thread and posting your cable connetions page and logs. That gives us a snap shot of your line info. I'd recommend starting your own so your info doesn't get confused with the OP's
