RPi3b with HiFiberry DAC+ Pro works fine with ethernet, but although it finds the wifi easily and logs on fine, it drops wifi quickly and has to be restarted. It seems like a common problem but I have seen no definitive fix. What's the fix? It's incredibly frustrating.

HiFiBerry team Some users reported that fixing the WLAN router to a channel fixes this. Can you try this? Alternatively an external USB WLAN stick usually works without problems.

Vijay I have the same problem (I always use fixed channels on WLAN routers after a local area scan). I will try a WiFi dongle tomorrow. This is unfortunate given the pi3 has built-in wifi. Is this a problem specific to Volumio or is the DAC+ Pro interfering with the wifi?

HiFiBerry team Hi,
what WLAN channel do you use. There are interferences on some channels. Check out this post:

Vijay Thanks for the response. I was using 11. I switched to 9 based on your link, applied on router, restarted Volumio, but still not connected. I am getting some auth errors and I have double checked my ssid and pwd. I have my router set to use WPA2-PSK [AES]. Below is my interfaces file content. Any other tips would be helpful.
auto wlan0
iface lo inet loopback
iface eth0 inet dhcp
iface wlan0 inet dhcp
wpa-ssid ***
wpa-psk ***
iface default inet dhcp

Vijay On another reboot of Volumio, I do not see the auth errors.I have tried rebooting the router as well. The behavior seems rather inconsistent. I do consistently get this error message though - ERROR: netdev:wlan0 already exists.
