dnsmasq failure
I was running V2.5.1.16 and have been for 6+ months no issue. The other night the internet went down and I logged into the Orbi via web and verified the provider issue. While there I noticed the up...
based on same thread and update from reddit;
i upgraded again to 2.6.2.104. Within 4 hours I had two more DNS outages. Same as before, DNS lookups to orbi router timing out. Log into router via telnet, reload the config (I'm not sure if dnsmasq was dead, just started documenting pid after last outage) and it started working again. On the 3rd outage I turned DST off (Advanced->administration->NTP->uncheck DST). I reloaded dnsmasq again (no reboots) and so far I've been good for 4 hours. Hopefully this fixes the issue. 1 hour off doesn't matter too much to me.
DNS servers from the ISP are not the issue so setting the router DNS servers to specific ones doesnt help. I would need the ability to change the DHCP DNS server given out so it is not the router/orbi which is causing internet outages when dnsmasq fails to respond to DNS queries.
I'm having this same issue. I'm on the latest firmware (2.7.2.104), and the issue started last week. Every few hours DNS stops working, so I telnet in and see something like this at the bottom of /tmp/dnsmasq.log:
Mar 24 18:12:23 dnsmasq[30353]: overflow: 1 log entries lost
I run "/etc/init.d/dnsmasq restart" and that fixes it, but it's obviously a pain to do that repeatedly. I'm debating adding that command to the crontab so that it auto restarts every hour or so.
I forget when I upgraded to the current firmware, but it definitely wasn't last week as I was out of town when the issues started occuring.
