RBR50 DNS issue

[lp1406]

My Orbi RBR50 router + 2 satellites have been rock-solid for years, until very recently when the Orbi "guest" network has become unstable because of DNS issues arising on Orbi's "Guest" network. 

My computer reports: "Your computer is trying to use a DNS server that is incorrect or doesn’t exist."  Re-syncing all the routers has not solved the problem. 

I've temporarily mitigated this issue by logging onto the Orbi primary network which does not [yet?] seem to be experiencing the same issue. 

I have read numerous posts of others experiencing the same issue over several months, but none appear to address my circumstances. 

Software version V2.7.3.22

Parental Controls OFF

Have you tried changing the DNS server? 

Are you using IPv6? There's also a dns server for ipv6 you can change. 

You can try googles 

ipv4: 8.8.8.8 or 8.8.4.4

IPv6

• 2001:4860:4860::8888.
• 2001:4860:4860::8844.

Netgear has set up a community forum specifically for the Orbi AC products. Most of the people who watch that forum are more likely to have experience with Orbi and know how to work it better than those of us who follow this router forum. Might be more likely to find someone who has a solution if the question is posted there:
