I've been using hub one since 2017, setup unchanged for more than a year I think, but in the past few weeks started experiencing problems. Wifi analyzer on my phone used to show a 5G signal strength of at worst -66 dBm at my desk, at the moment the best I can get seems to be about -75, and it often drops lower than that.
I assume signal strength isn't under software control, and this means the hardware is failing?
(The only thing that has changed recently is an Echo Spot and a Kindle added to the house, I saw some threads about Amazon devices causing problems, but I still have an issue when the Echo is unplugged and the Kindle powered down.)
