Hi there!
I have an Orbi standalone that I use as the router for my home. I am using the R510 satellites provided in my Lennar home. I have noticed that recently, some apps (like using Amazon) state that they have no internet. When I did this on my PC, it stated that the DNS could not be found. I tried connecting to the wifi SSID that is linked directly to the router and not the satellites, and it is much faster. What do I do?
