I’ve done the test you suggested : using regular Rpi2 power supply.
the 24h auto-deconnect is still at work.
I wonder if I can change the Wlan power options without using the webinterface.
Hi Heiner,
Here after my config description:
USB dongle : TP-Link Archer T1U Nano Adaptateur USB Wi-Fi AC 450Mbps
Encryption protocol : WPA/WPA2 mixed
Power supply through HifiBerry DAC (65W)
and this is it for the setup.
