Guest WiFi Internet Access Suddenly Stopped

[mocamaster]

Hey all, I have an AX88U Pro 3.0.0.6.102_32843 running as the main router with two AC68U in AiMesh mode (both on 3.0.0.4.386_51668). Today out of nowhere my guest networks internet access stopped working.

I deleted both and recreated them and no matter what I can't get internet access regardless if I toggle on/off "Access Intranet".

Has anyone run into this same issue? It started this evening and now I can't get my Guest Networks to access internet. I updated to 3.0.0.6.102_32843 for the AX88U and AC68U 3.0.0.4.386_51668 on December 8th and everything has been working fine until now.
Thank you for any insights.

Here is the funny part, while connected to the Guest WiFi network I am able to search Google and get results but I can't load any of the sites. So search results work on google but not loading the sites. DNS?

Resolved: Once I created the Guest Networks again in Guest Network Pro I noticed that there was no DNS specified. So the google app on my phone could query search results because I guess the Google app knows it's DNS 8.8.8.8. Once I entered a DNS for my Guest Networks they were able to get internet access again. I have no idea what triggered the change today to my guest networks but I am glad I solved it and I hope it helps someone else out there.

I wonder why 'connect to DNS server automatically' did not work... maybe a firmware defect.
