Hooking up your Raspberry Pi
It's very easy to properly set up a Raspberry Pi. If you can build a Lego set, you can build your Raspberry Pi computer. The following steps will help you in this:
- Place your SD card into the SD card slot on the underside of the Raspberry Pi.
- Connect the HDMI or RCA cable to the respective connector on the Raspberry Pi, and plug the other end into your monitor.
- Plug the Ethernet cable into the Ethernet jack (not applicable to Model A and A+) on the Raspberry Pi and the other end into your router or switch.
- Connect the USB mouse and keyboard to the two USB ports available on the Raspberry Pi. If you are using Model A, connect a USB hub to your Raspberry Pi and the mouse and keyboard to the hub.
- Plug the power supply's Micro USB connector into the Micro USB port on the Raspberry Pi to turn it on.
- A red LED, by the USB ports, will light up to indicate that the power is turned on.
- On your screen, a square rainbow image will appear for a brief moment, followed by some quick moving text or a graphic loading screen.
Congratulations! You have successfully booted up your Raspberry Pi!
Connecting to a Wi-Fi access point
The Raspberry Pi and Raspbian can easily connect to the Internet via Ethernet, but when using a USB wireless device, you can also connect to a Wi-Fi network. Raspbian includes a graphical utility to make connecting to a Wi-Fi access point easy. Go through the following steps:
- Boot up your Raspberry Pi.
- At the login screen, enter your username and password (default is
pi
andraspberry
, respectively). - In the command prompt, type
startx
to launch the desktop environment. - Using your mouse, double-click on the WiFi Config icon that is on the desktop.
- The Wi-Fi configuration tool will appear shortly.
- Click on Scan to scan for available wireless networks around you.
- Double-click on the one you wish to connect to.
- If it is a secured network, you will be asked for a password.
- Enter the password and click on Add.
- The Status: Disconnected message should now change to Status: Completed.
- You are now connected to your wireless network.
Note
wpa_gui saves your connection information. If you logout or reboot your Raspberry Pi, it will automatically try to connect to a previously added access point.
If you do not see wlan0 appear in the wpa_gui, or if your Raspberry Pi is unstable, you might need to use a powered USB hub. You should connect your device to a powered hub, and then connect the hub to the Raspberry Pi. This will ensure that the correct amount of power is received.
