Don't know about others, but I notice the Smart Clock will reboot by itself once a day, if not being used to stream content.
After identifying the 5GHz WiFi / MAC address issue, it's happiest connected via 2.4G WiFi but still restarts and connects itself back up to its configured 2.4G WiFi channel.
Reboots only seem to happen when it appears as idle.
Today I noticed what looked like the initial registration process being completed without manual intervention, which leads me to believe a Firmware update may have taken place.
Firmware version displays as 1.52.250291
If a new firmware was in fact applied, does anybody have one of these that could take a look at what version is running on yours?
