In the classroom, all the Raspberries have to be connected to wlan network with SSID timohei. Click on the network icon at the top right corner to see available wlan networks. Click on timohei; you will be asked for a password that I'll provide in the class. The network icon will blink for a while as the connection is being made. When connected, test the connection by opening any web page with a web browser.
Check you Raspberry's IP address by opening a terminal window and typing at the prompt:
ip addr
