Wifi on RPI3B+ Hifiberry Digi+ : Can't connect to my SSID


I have one RPI 3B+ with Hifiberry Digi+ board with Volumio.

  • one standard USB dongle for Wifi.

In the Network configuration, I see the list of SSIDs, I see mine but impossible to connect. It never works.
Ifconfig show wlan0 but it never gets any IP because it doesn’t succeed to connect. I tried to connect to other SSID and problem is the same.

Any idea?

Is your USB dongle in this list (wireless-adapter-compatibility-list-t2150.html) ?

If you have a RPi 3B+ you don’t need a dongle for Wifi. It is part of the 3B+. Have you tried it without the dongle?
