I use RPI2, latest Volumio 2 ( up to date) , with wifi dongle (power-management OFF). I have two of these. Both have manually set IP in the router (static in volumio does not work with radio as it seems).
Both occasionally drops the connection and becomes unreachable or more often with the running volumio circle for quite some time (sometimes several minutes). In the former case “F5” does not work but it will sometimes just come back after a while, else the is only one way to solve it - restarting by unplugging the AC. In the latte case using “F5” sometimes works but most often it is just to wait - the system so to say “lagg”.
My router says they are online.
It seems to me that this only occur when I have not used Volumio for a while - but I have checked that the WIFI-powermanagement is off. Maybe it is a feature that suspend Volumio if not used? If that is the case is there any way to turn that feature off?
One solution could of course be to ping the volumio every X minutes. I have not tried that.
Does anyone have the same problem? Any solution?
