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...
Same issue here -- the following has been happening for a few days now:
1) At least once every 24 hour period all of my 56+ devices (smart house) are no longer able to find internet -- note the wifi signal is fine and my LAN works great
2) Manually configuring a device with DNS works around the issue entirely, but practically I can't configure DNS for all of my smart devices
3) Resetting the RBR50 or even just pressing the "Test" button in the Internet Setup page in the Admin interface resolves the issue for another ~24 hours
I updated the firmware yesterday to V2.7.2.104, but no change in behavior. I would very much like to avoid a factory reset, so I am trying the NTP server change and disabling DST as suggested by others here.
I was abble to reproduce the problem with debug enabled. Log files have been set to the engineers.

thanks...that would be like the 'firmware' engineers.
Hi, all,
A long-term fix for devices that absolutely need access is to explicitly set them to use DNS other than through the router-as-relay. I.e., set the DNS on your laptop, phone, whatever to something other than 192.1.6.1.1 (as provided by the DHCP of the RBR50 router).
It is possible to set the RBR50 DHCP to provide that information, but not to ensure the configuration is persistent across reboots (it would be nice if that were a configuration option, though!)
Make that 192.168.1.1, below...
