C7000-100NAS randomly drops internet connection
Hello, My C7000-100NAS modem seems to randomly drop it's Comcast connection. This happen on 2.4 ghz, 5 ghz, and wired connections. There is no pattern, however the dropped connection usually last...
I have the same issue, and had them send me a brand new replacement, wich took 2 months of hoops and bull**bleep** to get, only to have the brand new device do the same. I didn't find this page until now, and they told me they had never had issues with this modem/router connecting or having t3 t4 t5 t6 errors and blammed it on my isp. I had the isp out 4 times checking my lines, and spectrum couldn't explain why it was happening. The artemis they gave me works and doesn't time out. So A) why would they claim not knowing about issues with this product since it has had issues dating back to 2016 with this exact problem, and why am I still trying to use it. We ALL should be reimbursed the $198.00 that we spent on this device, as it clearly does not work. They will be calling me back tomorrow, and I will let them know I have found this page and see what they say. I doubt I will see any money from this, sad cause I have used netgear products for well over 8 years. DONT BUY THIS DEVICE!
Certainly a frustrating problem. I had the same for several months, and needed to reboot to regain the connection and "contract speed" with the ISP. One reliable fix was to reboot the cable-modem. I decided that the issue was with the "modem" part of the C7000, and the fact that the ISP provider is in charge of updating the software (it does need to be compatible with the ISP's hardware). The current firmware version is v1.1.29, and this version works fine. I suspect that the cable feed gets corrupted from time to time as well - another source of connection issues. So, a reboot does help to restore the cable connection, identify the subscriber and establish the permitted speed, functionality, etc. I have 14 devices connected, 3 hardwire, 11 wi-fi; and use NeGear Genie to "control access" to the system. The combined "cable-modem" device sounds great, but separate units may be easier to troubleshoot and update (router in particular). However, in the past and using a separate modem unit, I did have problems with the ISP provider's firmware updates - and they did have to return to the a prior version for all endusers on the system. In conclusion - it's probably the modem part of the device (ISP and connection reliability, maybe the firmware version, etc.); and the only solution appears to be a reboot (automate with a timer) or get separate units to better isolate and solve the problem.
