RBR50 intermittent DNS lookup issues
I have RBR50 (Firmware V2.7.2.104), with one RBS50 satellite, connected to a CM1000v2 cable modem, Comcast ISP. Starting 3/14, I sporadically get DNS lookup errors. I've tried setting DNS servers t...
I am experiencing EXACTLY the same problems
RBR50, Firmware V2.7.2.104
ISP is Comcast
Problem started March 14, still here on March 17 - lose internet connection multiple times, generally 1 to 2 hour intervals
Same issue whether I allow ISP to pick DNS (75.75.75.75 / 75.75.76.76) of I manually select DNS - OpenDNS (208.67.222.222 / 208.67.220.220)
Problem extends across all devices - wired and wireless, Windows, Android)
Test Internet button seems to temporarily fix the problem.
Nor recent changes to firmware, ISP connection or the devices used.

Better yet - tell your customers that its a support issue and requires payment to fix despite it being something you insterted via firmware update or other.. oh wait - you already are doing this!

If you'll look around in this forum, several moderators have reached out offering to help. Perhaps you should do that.
Sure... but should I have done that prior to calling support? Is that the new standard... Hunt and peck around for their issues they introduce? Imagine all the old folks getting fleeced by them because of people who call in first..
I'm willing! I sent a private message.

Unsure FW but issues occurred around DST and FW upgrade

Same issues as I see many others have in the community. The Orbi network seems to be working and I have internet connectivity on some devices and not on others. For instance, my computer and Rokus work but cell phones say there is no connection to the internet. Sometimes just the Rokus will work and the computers will have the same no internet message as the cell phones. This makes no sense to me. I have rebooted the main and satellites several times.
A little more information:
IPv6 DNS entries appear to be not working correctly.
If I leave the configuration to "get automatically from ISP", then there is no entry in /tmp/resolv.conf (i.e., no override).
If I put in a DNS entry "use these DNS servers", then the entry in /tmp/resolv.conf is NOT what I entered - it is the value the router gets from my ISP.
I don't know if this is related to the overall DNS problems we've all been seeing.
PS - ROKUs may work (some apps at least) because they have hard-wired IP addresses for DNS servers in the public Internet (e.g., Google 8.8.8.8).
Laptops, phones, and pads typically take the DNS info from their DHCP response and use that; the Orbi always tells them to use the Orbi as the DNS server (192.168.1.1). That works fine until dnsmasq crashes and fails to restart, at which point the Orbi no longer does DNS caching relay or DHCP.
You CAN login and restart dnsmasq. You can setup a cron job to do that automatically, at least until the system reboots (it loses that state). You can also reboot, which will start dnsmasq again.
childre9, do you have Traffic Metering enable? If so, disabling that and a router reboot should fix it.
That appears to have worked. Phones and computers are online. Netgear should pay you for your help here, but I thank you.
