Nighthawk C7000v2 Freezing

Wanted to know if anyone else who purchased this cable modem router has had the issue of the unit just freezing up and it not working.

Purchased this in 2023. Had it activated with Spectrum and the issues began. Was on with tech support both Spectrum and Netgear for a straight week. Decided to go back to my old Spectrum supplied modem with my Nighthawk WiFi...

Last week, since I still had the unit as a paperweight, decided to try it again. 

Same thing happened and after a day put it back in the box.

Since I no longer have support, has anyone had the same issue and/or has something been off with these units that someone has figured out?

I have looked at the community blogs and seems that some people did hard resets, firmware updates to correct the issue but I have also done the same only my results have not made the unit viable.

    Hey Furrye.. Worked with the ISP all day yesterday.. even left it overnight to see if a push of firmware happens and the unit would not communicate with ISP.. Lots of errors and I think the unit itself is defunct so it's going into the recycle bin.... Thought the netgear hardware would be better than the others but I was wrong...

    Thanks for all you time and help....

      Man that’s disappointing to hear, I’m having the exact thing happen with mine right now. 
      I thought it was my network being compromised or something more nefarious at first so I factory reset and changed the network name and passwords, etc.


      It’s been an all day thing unable to get work done because of it and the dumb nighthawk app just says UPDATE firmware and wont connect and cable status keeps dropping randomly.

       

      Spectrum is typically the nightmare culprit but using my old 2014 router worked when I plugged it in so I guess Netgear lost loyalty with me and have to replace mine too.

        Yes... so I took it to Best Buys and got the credit for a trade. Called NG and went over it with them on how I purchased the unit, and it was never used. Which is the truth as I was just so busy. When I called, it wasn't to get tech support but to ask what the issues were as I/we are not the only ones and there were a few others that had the similar problem.Most people turned their in and received replacements. Was on the phone with them for around 45 minutes going over the issues. He finally was kind enough to send me a 10% off any of the Wifi 7 units.. not combo like I wanted.. and just got it last week.  The W7 can handle my speed at my house.. I have 500gb service and the unit is working stellar.......

      Looks like there is no signal on the modem side. There should be some signal on the first range of channels. Nothing is locked in. 

      I recommend getting the ISP to send a tech to have a look at this.

      Can you get a top portion of the channels on the downlink channels 1 thru 20 on the cable connections page?

       

      Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.

    Hey Guru.. 

     I would have to have it activated again and get that info.. Pain in the ass but will see if I can do it... Will also clear whatever the event logs etc before the activation.

     

    Thanks.

      Don't clear anything, just get it online and say 5 minutes after it's online take a capture of those two items

    Thanks for replying.. I can..

     I can access it, change the wireless and all the settings... give iti an hour.. if that.. and it freezes.

    I then have to reboot  and wait for it to connect to the ISP and then .. it goes out...

    This time, I could only take 2 days of the constant outage before I reverted back to the original modem

     

    v1.03.01.0 is the firmware

    Let me know your thoughts

    Can you access the modems web page at all when this happens? 

    Both ethernet and wireless connections fail if this happens? 

     

    What Firmware version is currently loaded?

    Please post a copy and paste of the modems connection status and event log page.
