How to use external wifi dongle

[Flavor]

I just received my CM3 DIY kit. But I am still a noob in this Pi thing, there are a lot of things that I don't understand.

- How do I use external wifi dongle? I have Mediatek wifi dongle, I don't know if it's compatible with CM3 or not.

To connect to WiFi, you can do something like this.

At least that will let you know if your WiFi dongle is working, because you will see your WiFi network.  If you need to supply a password, it can be tricky if you only have 1 USB port.  I have had it work to try to connect, when it asks for a password, unplug WiFi and plug in keyboard, type the password, then swap back, wait a moment, and then hit OK.  I've also had it fail sometimes.

There's another way to easily set up the WiFi using /boot/wpa_supplicant.conf which would look something like

Code:

network={
   ssid="«your_SSID»"
   psk="«your_PSK»"
   key_mgmt=WPA-PSK
}

But that won't easily tell you if your dongle is functioning (like the video method should).
