PX50 in router mode...

Whenever we lose and then restore mains power, our master PX50 invariably stays in Red (offline) mode and does not reconnect to the fibre broadband and boot to Green. We have to power-cycle the master PX50 to get the system back up.

Why does this happen and can anything be done to get the master px50 to boot to green? Even if internet connectivity is down, 'surely' the px50 should boot up to a point where the WiFi etc. is running?

The current situation is inconvenient and annoying when we're at home - it's actually a major issue if we're away because the broadband will recover but with the Decos down, we don't have any control or access to our security and general IOT monitoring.
