Pi keeps stalling

[JustCurious]

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.

Have you been in touch with IQaudIO ?

Have you been in touch with IQaudIO ?

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

[RaTTuS]

staling how ?
does dmesg say anything

[JustCurious]

staling how ?

Ping times out and ssh/telnet get no response. (t.i. wirelessly)

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
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 004: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]

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.

Thanks MrEngman! That works!

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)

[thaddeussmith]

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.
