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...
Yeah, mine get worse as time goes on. It isn't wireless coverage or signal overlap as I'm a Network Engineer by trade and know how to scan and scope interference issues.
As a good test or temp fix, if you want to see if you're having the same problems as I am (which is likely), when you have wireless related issues: FIRST, disconnect from your 5Ghz network either by disabling/re-enabling wireless or connect to your 2.4Ghz network THEN switch back to 5. Either way, when you disconnect and reconnect from your 5Ghz network, it will (or mine does) connect and work fine for a period of time (10-15 min). Some longer than others. On occassion, I just have to power cycle the C7000 altogether.
I went ahead and took an AeroHive AP which is enterprise class and placed it on a different frequency as the Netgear using the netgear as a local router and the AeroHive as an isolated extension but different network and BAM, the AeroHive works flawlessly as a wireless router while the Netgear (which is in the same room) continues to flake out wirelessly and sometimes as a modem.
It just can't seem to handle any kind of small error correction. Instead, it flakes out for all clients on the 5Ghz network without correcting whatever issue it's having until it reinitiates that connection either by disconnecting the client or restarting the C7000. Pretty bad bug IMO.
SupaPig It is still happening with this account--- I have wired most of the main computers on Ethernet GB backbone so there are only a few that will use the 5Ghz along with customers will use the 2.4Ghz. Looking at the logs it is doing just like you were talking about. I have been working with Netgear support for approx. 2+ years on my home base system (started out with R700 than R7500 and now R7800) due to many issues with code and hardware. The current one that I am now using R7800 has been more stable but it has it issues that we are still working with. If this account were tasking the 5Ghz they would be complaining more. Since for the most part they are not noticing the errors due to them not using their laptops, etc. on a ongoing basics. They are using them between patients they are working on for updating info about what they are doing with each patient. This does not let Netgear off the hook to fix the code.
I'm having the same issues as everyone else. Only had this modem/router for 1 week and it is complete crap. Internet is constantly going down and affects both wired and wireless devices. Often have to reboot the router. Has anyone found a resolution? Or a better replacement? I'm on TWC
Hello bcmorrison
Are you able to go into the logs of the C7000 when it drops internet to see what errors are happening?

I am not a computer engineer, but my son is. My ISP is small and says they don't have the ability to upgrade firmware. Netgear promised to send me a replacement with upgraded firmware (to .23 release, from .15) but what they sent me STILL has the old firmware, still has problems with intermittent wifi dropping of signals. I have spent HOURS today, trying to trouble shoot--hours on the phone with Netgear who now says their "new" modem-router does not come with suport! Netgear wanted me to pay $49, after they'd kept me on hold. They promised again to send a new modem-router, this time with the updated firmware, but the promised email, detailing their agreement never came. I am at my wit's end. If I'm to throw out this $200 piece of equipment, what IS a reliable modem AND router, or modem router? I just don't have the expertise and patience to keep dealing with this kind on NON-customer support!
At this time (for you), there may be only one fix for this problem (other than a different brand of equipment) - the C7000 needs to be "reset" in order to return to proper functionality. This can be easily done each night (or early morning) by using a $5 electrical timer that disconnects power to the C7000 each day from 10 minutes to an hour - what ever is most convenient for setting the timer's "ON" operation. Shutting OFF and then powering up the unit with restore it's functionality until the Cable Supplier's signal again causes the C7000 to malfunction. If the malfunction occurs when your needing internet service, then logon to the C7000 and reset the Modem from your PC. On "restart", the problem should be resolved. The updated C7000 software requires the Cable company to install, since the revised software must be compatible for their system. The problem you are experiencing will be resolved once the Cable company upgrades their service. This is a good example/reason for using separate modem and router units. In the case of the C7000 modem/router, it is likely that the modem section is at fault - or the combination of this particular modem and the Cable company's system.
Thank you for the reply. Actually tried the reset and several other approaches. Seems kind of senseless to have to do a power interupt in order to get a device working correctly IMO. This particular C7000 was the problem. Since repalcing this device on my network over a year ago, service has been flawless.
I can also attest that using a electirical timer to power off the router once per day works.
This is considered a COLD REBOOT because you are removing power from the unit.
It is finally what I had to do and things seem to be fine most of the time.
There are still occasions when I need to do a manual REBOOT.
For a manual REBOOT you want to login to the router and do a "REBOOT" not a reset.
This is considered a WARM REBOOT because power is never actually removed from the unit.
A reset would reset the modem to factory defaults which may not be what you want.
My router has the .23 firmware but I have not removed the timer yet. This will be something I will try one day.
In my opinion having to do a frequent reset (of any kind) is not a viable solution and is most certainly a horrible user experience.
