I have installed the latest volumio on old rpi mod.b. I have a wifi usb stick. When i configure wifi for about 5 minites it work well, after lost the connection and it doesn’t reconnect. The system report a message in the settimg menù:
Command failed :Sudo /bin/Systemctl restart wireless.service. Job for wireless.service failed because the control process exited with error code. See systemctl status.wireless.service amd journalact-xe for details.
Could someone help me ?
