I have microwave internet that comes through a Google Wifi Mesh point that acts as the main router. From there, it goes to an unmanaged switch, which connects to various devices. It also connects to another 3 mesh points (1 on far end of house, 1 in garage, and the third in the shop (which is connected via an ethernet to fiber media converter as the shop is several hundred feet away from the house).
The network works as it should, though a bit slow (not sure if there is a config issue or the microwave internet is just under performing by a lot) The problem is, all the devices, and the connection show as offline in Google Home on my android. Doesn't matter if a reset the devices, remove from power, whatever. It worked fine for a long time and then just went offline. I checked and I have the most up to date version of the app. Anything else I can try?
The only thing I can suggest is an attempt to force a firmware update, but depending on what version of hardware you have, that might not be easy to do. Unfortunately after several months of nothing, it fixed itself so I don't even have a solution to share with you except that I hope yours does the same, but faster! Good luck!
It looks like we've slowed down here. We'll be closing up the thread unless anyone else has any input or needs anything else. If so, just let me know and we can keep this open a bit longer.
