Hi. I'm currently having problems with waay to thick walls and the resulting weak signal between the mesh points. I am really missing some technical information, on for example: Whether the mesh network is in a 'star' or 'chain' configuration, where exactly in the ?chain the signal (packet) loss lies, and in general, how well the connection between the points themselves is. Currently it's a cat-and-mouse game of repositioning the points until it works for some time.
I think the Google home app has improved it's capabilities in that regard with the latest update, but that's just not enough. The optimal solution imo would be a mesh-graph of the points with the lines in between showing the packet loss (effectively the speed reduction) in percent, and not some useless Great-Good-Weak rating, that's depending on the blessing of your internet provider and what speed you are paying for.
Mesh is using 802.11s.
Thick walls stopping you: What about wired backhaul? If ethernet cable is not an option; ethernet over coax (MoCA), or powerline?
