I’ve got three RPis here running DietPi and Roon Bridge. Two of them work fine, and they are connected via Ethernet cabling. The third RPi uses WiFi, and it seems that after 24 hours or so, the WiFi connection disappears. I need to power cycle the RPi, and then it’s up and running again.
I say “after 24 hours or so” because I’ll be using the RPi one day (it drives my headphones in Roon), but when I come to use it again the next day, the RPi will have disappeared from Roon because the WiFi has gone (I can’t ping the RPi or PuTTY into it). So I have to power cycle the RPi to get it back again.
This behaviour has existed for at least the last few upgrades of DietPi (Roon shows I’m currently on Linux 4.9.27-v7+).
Is anyone else seeing this? It’s certainly not a showstopper, just a minor irritant, but I would like to get to the bottom of it. If no-one else is seeing it, I’ll try switching to the IQaudIO Roon Ready image (the RPi has an IQaudIO DAC+) to see if that makes a difference.
