Connecting to the Arduino YUN (WiFi)

This guide will help you through the process of connecting to the arduino Yun using WFi.

We are firstly connecting the Arduino Yun using an USB cable from a computer to power up the board. When power is connected, a¬†green “on” LED should light up. The linux part of the Arduino will now boot, so leave it for 1 minute or so. When the booting is done two¬†additional LEDs (red and white) will come on. Now you should be able to connect with the board through wifi.

On the PC (assuming Windows) you should now see a network with a name similar to “Arduino Yun-90A2DAF519F8”. This is the name of a network created by the Yun. The last 12 characters are the MAC address of the Yun, so the network name will be unique. Connect to it and then afterwards open up your standard browser and enter the default IP-address (192.168.240.1) of the Yun. This will take you to a webpage similar to this.

For an Arduino YUN with standard configuration the default username is “root” and default password is “arduino”. On the this webside you will only need to fill in the password. Doing so will take you to the following site.

Here you can see the network information. On to you can click “Configure” if you are going to change the settings of the Yun, however, make sure you know what you are doing since you can make the Yununresponsive if you make wrong connections. In that case you will need to reset the network config by holding the “WLAN reset button” for five seconds – see “Resetting the Arduino YUN“.
