Can’t access some sites with Orbi

I spent time on the phone with Orbi support the first time I started realizing the new router was the problem. Support had me login via web browser and rebuild the network and that worked temporarily. Now it’s constant resets and occasionally rebuilding of the network via the Orbi app. I should clarify that this is not limited to solely google.com. I should also clarify I have just enough knowledge of this area to get myself in trouble. I do not even know what DNS is. I have no advanced or custom settings on my network. Not even using a guest network. If returning this was an option, I would at this point but, too late for that and I’d feel guilty selling this expensive router for someone else to have problems. I do appreciate your trying to help though man.
