RBR50 DNS Issues
Have the Orbi RBR50 all on the latest firmware. Have reset the entire router and satellite units. DNS keeps locking up. All devices connect to the Orbi fine yet when accessing the internet it locks u...
I have an RBR20 and in the last few weeks have been having the exact same issue. I'm a professional IT person by trade, and have a lot of networking knowledge, including previously being employed as a network engineer for a large software company - so I know a lot about how to troubleshoot issues like this.
- I am on firmware version: V2.3.5.36
- I use CloudFlare DNS: 1.1.1.1 for default
- I have also tried using a variety of DNS providers, including my own ISP, Google, etc. Same problems.
- I am using Circle for the kids in the house.
- I have tried turning off and on circle through the Orbi settings, as suggested in this thread - seems to have no impact on the issue.
I have done a lot of investigation and determined, when this DNS resolution issue happens:
- DNS resoltuion through the entire home, on multiple devices stops working, using the forced resolver of the Orbi (192.168.1.1 on my network)
- Manual DNS resolution on devices like my laptop works fine. I.E I can do a NSLOOKUP or DIG (depending on OS) of domains normally.
- DIG @1.1.1.1 google.com -> resolves properly
- DIG @192.168.1.1 google.com -> hangs and eventually times out
- Pings and public internet access (over IP only) work fine. This is definitely just a DNS issue.
To resolve the issue, what works is either:
- Rebooting the Orbi RBR
- Logging into the Orbi admin page, clicking on "Internet", clicking "Test". It fixes it a bit faster, without a full reboot.
I'm pretty sure what is happening here is that the Orbi is running dnsmasq or something similar locally, and it just hangs for some reason. Hitting "Test", or rebooting the router obviously clears this issue.
The issue appears to happen randomly. There is no specific timing between incidents. Sometimes we will go a few days without the issue, sometimes we will have it happen multiple times in the same day.
It's really starting to frustrate me. Hopefully someone from Netgear or elsewhere knows how to fix it. I'm guessing at this point it's likely going to require a firmware fix :-(
netgear - Please help!
What is the Mfr and model# of the ISP modem the NG router is connected too?
Does using default DNS or letting the RBR auto detect and use DNS keep the DNS running for your devices. Try quad 9?
Has a factory reset and setup from scratch been performed since last FW update and use auto DNS?
Circle has been know to cause problems as well. Try a reset and setup from scratch with out any Armor or Circle.
If any of these fail to resolve anything, please file a support ticket here:
