Error DNS_PROBE_FINISHED_NXDOMAIN after update to V1.0.1.70_1.0.44 of firmware

Hi all,

Ever since I have updated my AC1750 R6400 router every other site I try to open gives a DNS_PROBE_FINISHED_NXDOMAIN error. If I refresh (F5), the website in question usually opens. It's a bit annoying. Of course I have no proof it's the update, but I had not updated the firmware for two years and had had no problems, and from the day I performed the firmware update the issue arose. So that seems a bit suspicious.

 

What I have tried: restarting my modem and restarting the router, a flushdns, switching browsers, but to no avail.

Could it be that something went wrong with the firmware update? When I performed the update, I did switch the router off when the network still wasn't up after twenty minutes. After switching it on again, the router seemed to function alright - except for this issue.

 

Any tips for how to troubleshoot or solve this?

Cheers,

sandokanfirst

  • Whenever I run into an issue after a firmware update, one of the first steps i try is a factory reset with a new install (not using a backup configuration)

    have you tried this?

    • Unfortunately, after a factory reset the issue persists. It's fickle. Sometimes websites load immediately, but the next I get either a DNS_PROBE_FINISHED_NXDOMAIN or 
      ERR_NAME_NOT_RESOLVED. Is there anything else I can do?

    • No, I haven't done that yet. I always dread the moment I have to reconfigure the router by hand, but I think you're right that is the wise thing to do. I will try that, thanks, plemans !
