Intermittent DNS lookup failures on RBR850
Intermittent DNS lookup failures RBR850 I've been using the Orbi RBR850 for several months now and I'm constantly having issues with DNS that I've NEVER experienced with any other router I've ever u...
Not sure, you can enable log capture and debug them yourself and see. router IP\debug.htm
Best I can tell (from reviewing posts here), this is soundly an issue with the dnsmasq implementation on the router. It's either a buggy version and / or a bad config. NG could fix this in less than a day if they spent some time on it....
Well the good news is that it looks like I can fix this myself.
I got telnet access and was able to check out NG's dnsmasq implementation which is pretty lack luster and has tons of room for improvement.
The configuration file for dnsmasq is complete commented out, they are relying on flags on the daemon launch entirely.
Here's what they are:
dnsmasq -h -n -c 0 -N -i br* -r /tmp/resolv.conf -u root
-h, --no-hosts Do NOT load /etc/hosts file.
-n, --no-poll Do NOT poll /etc/resolv.conf file, reload only on SIGHUP.
-c, --cache-size=<integer> Specify the size of the cache in entries (defaults to 150).
-N, --no-negcache Do NOT cache failed search results.
-i, --interface=<interface> Specify interface(s) to listen on.
-r, --resolv-file=<path> Specify path to resolv.conf (defaults to /etc/resolv.conf).
-u, --user=<username> Change to this user after startup. (defaults to nobody).I'm going to tinker with these values and see if I can better optmize this. If I fix it I'll share my solution.
Pretty sure not running cache is bad.....
