Getting DNS_PROBE_POSSIBLE error on R8000
In about the last month and a half, I have started noticing two things: * pings spike every 5 minutes, from about 8-9ms, to over 1000ms, for 5-10 seconds (this messes up Remote Desktop) * DNS_PR...
Final Solution
- Rolled back the router firmware from .76 to .68 and everything works perfectly again. Upgrade to .76 and everything fails again. Back to .68, everything good again. One post this chain mentioned that it had been fixed in a beta version but never made the final released version. Come on Netgear! Get this solved so I can get back to current firmware.
- Old version (working) = V1.0.4.68_10.1.75
- New version (not working) = 1.0.4.76_10.1.82
Scenario
I browse to a website, a valid functioning and available website, and I get the "Hmmm…can't reach this page" in MS-Edge browser, similar kind of thing in chrome. It says "DNS_PROBE_FINISHED_NXDOMAIN".
Evidence
- Error Message
- F12 Browser Dev tools shows no "request" or "response". Clearly a DNS issue of some sort.
- The odd thing is that it could be a site I just went to and is theorically cached.
- Also, I just keep hitting refresh and eventually the URL loads successfully.
- The refresh workaround is only good on "whole page" situations. When a page loads and then does client side calls to get REST api data it just fails and I can't make it retry so SPA apps are a real problem. Oddly, keep trying and eventually it might get through. F5 refresh, click SPA button to retrieve data #FAIL, F5 refresh, click button again, might work.

Work Log

- Get DNS IP dynamically
- Set DNS manually to OpenDNS server addresses
- Set DNS manually to Google 8.8.8.8 and 8.8.8.4 addresses
- No love
- For some time now, perhaps 6 months, I've been receiving the above error on many simple browse attempts on many different sites.
- Tried changing my DNS settings, no success
- Tried turning off VPN on my router
- Tried turning off DynDNS on my router
- Tried resetting my router
- Browsed (between errors) and found the rollback solution.
I have the same problem with the Nighthawk X6 R8000. Firmware was recently upgraded to V1.0.4.76_10.1.82 and immediately got DNS_PROBE_FINISHED_NXDOMAIN errors in Google Chrome on multiple computers connected to the same network.
- I downgraded the firmware to V1.0.4.68_10.1.75 which appears to be working.
Yes this works, unfortunetly it will leave your router open to a huge security risk
