R6050 DNS drops every 1-2 hours

Hi all,

 

This issue has been happening for a few weeks.

Every 1-2 hours I get the "This site can't be reached" message due to DNS issues.
It also causes similar issues on all other network devices (both connected via LAN and wireless). 

The temporary fix is easy, I just click the "Apply" button in the "Internet Setup" tab in the genie, and a few seconds later everything works again.

I've tried:

  • Rebooting the router and modem
  • Factory resetting the router
  • Changing the DNS address to Google's DNS servers
  • Turning off all anti-virus and firewall programs

 

Possibly useful info:

  • The issue rarely occurs overnight (but it does happen every once in a while) as I'm able to use all my devices for around an hour when I wake up.
  • I was away for 3 days and when I remotely checked my smart thermostat a few times it was working. 
  • I'm using the most recent firmware version: V1.0.1.26_1.0.1
  • I'm using a Netgear cable modem CM700

Any help would be greatly appreciated. Thanks!

    Are you using ipv6? 

    If not, enable it. 

    If so, make sure to change the IPv6 dns server as well. 

     

    what speeds do you pay for? The R6050 is a pretty anemic 10/100mbps router. its not gigabit capable and even its wifi is pretty slow. Depending on what you pay for, an upgrade might make a significant difference.

      This is important.

       

      DFO says they have the CM700 modem. That has Gigabit Ethernet output.

       

      With Internet speeds faster than 100 Mbps increasingly common, especialy on cable services. I would not be surprised if the modem was delivering more than that to the router, possibly wasting a lot of the bandwith that DFO is paying for.

      plemans michaelkenward Thanks!

      Apparently, the R6050 doesn't have the option to switch to IPV6 (I looked & researched it)

      Additionally, my internet speed is 100/10mbps.

      Any other suggestions?

        That is on the edge of your router's capability. Take off the usual traffic processing overheads and your router is a  bit slower than your Internet speed.

         

        Take in the possibility that your ISP delivers a bit more than 100 Mbps, many do, and you may lose abut 10 per cent.

         

        You can test that by running a speedtest out of the modem.

         

        Then there is the local traffic on your own network. You could increase the speed there siginficantly.

         

        My advice would be to buy a new router, one that also meets your other needs.
