RPI3 + Official WiFi dongle: can't get it to connect

[dangert]

I am having difficulties using the official RP wifi dongle with Rune (latest official image, RuneAudio_rpi2_rp3_0.4-beta_20160321_2GB.img). I don't have a problem with builtin WiFi, nor I had a problem with stock Raspbian and the dongle.

The device is displayed correctly under Network and is able to see my SSID, but nothing happens when I try to connect: it stays disconnected. The reason to use an external dongle is that I've read that the builtin one is not intended for streaming, but only for IoT tasks.

Is official dongle supported or I better try a different one?

Thank you, Frank. I didn't know it is necessary.

Is my statement about internal WiFi correct (low powered and not suitable for streaming)?

Thank you, Frank!

Blacklisting the builtin adapter didn't help. When disabled, the WiFi dongle wasn't detected at all.

Hi danger,

sorry it was my mistake.
The official usb wifi dongle uses the also a broadcom, so disabling it was for sure not a good idea.

Is there anything else I can do? With stock Raspbian the dongle was working.
