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 as KevinDubs
RBR50, Firmware V2.7.2.104
ISP is Comcast
Problem started March 14, still here on March 16 - 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 (8.8.8.8 / 8.8.4.4)
Problem extends across all devices - wired and wireless, Windows, Android, iOS, and Echo units)
Must reboot the modem to regain internet services'
Nor recent changes to firmware, ISP connection or the devices used.
What is going on, and how do we fix it?
Others in that reddit thread methioned checing your NTP settings to ensure they are correct.
What is the Mfr and model# of your modem you use?
If this problem just appeared long after a FW update, seems like this maybe a timing issue with the recent DST time change. No idea why that would effect DNS or Orbi though.

- I did a factory reset last night to resolve per others have suggested on the reddit thread. It's ok so far but it's only been 8 hours. Will report back if I encounter the issue again.

I'm using the latest firmware - V2.7.2.104. Did not reinstall, just did the factory reset with the physical reset button in the back of the units. I reset both the router and satellite and had to set everything up again.
