Part 2. Connecting To WiFi

Once your Yun reboots with the updated OpenWRT, you can configure its WiFi settings. Make sure you're still connected to the Yun's WiFi and visit 192.168.240.1 again. In the top right corner you'll see a "Configure" button:

The following page allows you to change your Arduino's name (this will change the name of its default WiFi network too), change the password, and change the Yun's timezone.

WIRELESS PARAMETERS is the section we're most concerned with. This is where you can find the wireless network you want your Yun to automatically connect to on boot. Carefully enter the network's password and click "Configure & Restart".

NOTE: Once the Yun is connected to a wireless network, you can obtain its IP address by entering 192.168.240.1 in your browser address bar or by entering arduino.local, but you must be connected to the same wireless network. This will allow you to SSH into the Linux part of the Yun. We are not going to do that in this tutorial, but you can read more on it here: https://www.arduino.cc/en/Tutorial/LinuxCLI

If you ever need to change the Yun's WiFi settings but don't have access to the wireless network it automatically connects to, you can press the WiFi reset button. You need to hold the button for somewhere between 5-30 seconds and no longer or it will be reset to factory settings.
