Pi keeps stalling

I use the RPi with Volumio and the Pi-DAC from IQaudIO. The RPi keeps stalling after a certain amount of time. Always when not operated (running though), and within between 10 minutes and 3 days.

Yes. My DAC board will be examined by IQaudIO. But what are you aiming at exactly?

What WiFi dongle are you using?
Have you disabled power management for it?
Post the output from a lsusb command.

Lsusb:
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I don't know how to disable power management of the WiFi dongle.
As for dmesg, I don't know what it means but I suspect it reports about the initialisation phase of the operating system.
It looks like Volumio (or the WiFi dongle) goes to sleep and I can wake it up by initiating a connection and waiting a while.

You can disable power management for thr EW-7811Un by making file /etc/modprobe.d/8192cu.conf.
Use command
Code: Select all
sudo nano /etc/modprobe.d/8192cu.conf
to edit the file and add the lines, well only second line is really needed.
Code: Select all
# Disable power management
options 8192cu rtw_power_mgnt=0 rtw_enusbss=0
Save the file and terminate the editor using keys Cntl-x, y, enter.
This will turn off power management and stop the EW-7811Un disconnecting from the USB bus.

What would be the proper syntax to create the same file/settings for this device?
Bus 001 Device 004: ID 0846:9041 NetGear, Inc. WNA1000M 802.11bgn [Realtek RTL8188CUS]
I'm having the exact same symptoms, but different device. Running Volumio 1.41 (raspyfi)

After re-reading the thread, I just realized that I'm dumb and the existing syntax should also work for my Netgear adapter. I was getting hung up on manufacturer names and assuming there was a difference.
