C7000-100NAS randomly drops internet connection

Hello Rreckr 

When do you seem to have the most drop outs is it at a certain time of day?

i will no longer be dealing with the company and it's products. i've been out of a intenet connection for the last 3 days. in these 3 days i've had access to the web for 10 minutes only for it to go out again.

i've already sent for another modem/router from another company and will be taking this one back as i'm well within the return window.

i won't mention the abysmal CS.

lesson learned. don't deal with netgear.

Hello Rreckr

When you are having these issues can you copy the modems logs and post them here you can get the logs in the modems settings then click Advanced-Administration-Logs.

As mentioned in an earlier post - try a "hard reset" to re-establish the default settings and possibly correct some hidden fault that is affecting the operation.

The "hard reset" will also re-establish the MAC addresses for the Cable Modem (default on the nameplate), plus the MAC addresses for the LAN port and the INTERNET port.  The later are sequental (in last 2 numbers) to the default Cable Modem MAC address.  After the hard-reset, change the "default" login username and password for the Cable Modem (for security), and reset the Internet password(s) to those previoulsy used - this should allow all previously "attached devices" to connect.  Leave all other settings alone until you can determine if the problem is corrected.

Comcast has been on this for the last several weeks/months and can't find anything.  However, their smallest test time is 5 minutes increments.  But I may have stumbled on the issues.  These statistics are for direct connect cable - computer to Router.

This site tests more than just upload and download speed.  i tests for Latency/Ping

We use MagicJack.  When we connect to a call, we loose the incoming voice for anywhere from 6 to 30 seconds.  We just keep talking, though that is hard to do when it is an answering machine or robo menu.  The tests explain what is happening.  But I don't know where to go with this.  Can't get to the right people at Comcast or Netgear.

When I ran this test the numbers in the beginning of the test were all over.  It looked like an EKG and then it is steady.  Something is happening at the beginning of the connection not only on the phone, but also when we go to other websites.

From "www.techrepublic.com":

Users successfully establish a VPN connection, but the connection periodically drops

There are a number of places you can check to try to nail down this problem. First, verify that your computer did not go into standby mode, hibernate, and that a screen saver did not pop up. Standby and hibernation can interrupt your network connection when the VPN client expects a constant link to a VPN server. You may also have configured your machine to shut down a network adapter after a certain amount of time in order to save power.

If wireless is in use, you may have wandered to a location with a low (or no) wireless signal (not the case here), and the VPN might have dropped as a result. Further, you might have a bad network cable, problem with their router or Internet connection, or any number of other physical connection problems.

Other Comments: Can you determine if the "disconnect" was from the PC to the wireless router, or was it from the internet source (cable) to the Modem? This would confirm whether the disconnect is an ISP problem or a Cable Modem/Router problem. The Unit's internal software (version number, etc.), can only be changed by the Manufacturer or the ISP provider.  However, I suspect the the Customer Service person can only change the settings that are available to the end-user. You might have a setting that is not the best for a VPN connection - and this setting can be either on the Cable Modem/Router or the PC's WiFi Adpater.  You may need to review these settings and "experiment".  Again, before "experimenting", see if you can confirm where the disconnect occurs - at the modem or between the Router and PC. If you have a HardDrive connected to the Router and can access the HD but not the internet - then the problem is with the ISP and/or the Cable connection. 

I have the same issue, and had them send me a brand new replacement, wich took 2 months of hoops 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.
