This is the third video in our 2013 five-part series Get Started With Pi for Raspberry Pi 2.
The Raspberry Pi has a 10/100 Mbps Ethernet port built in so it’s easy to wire your Pi to your router with an Ethernet cable. The LED lights should begin to flicker when you boot up the Pi.
Make sure your router is configured for DHCP (Dynamic Host Configuration Protocol) so that the Pi will automatically be assigned an IP address on your network.
In the video we use the Wi-Pi USB to connect the Pi to a wireless network. If you’re running Raspbian (as we are in this series) then this is truly a plug and play accessory. Wi-Pi uses the latest 802.11n wireless technology and can support data rates of up to 150 Mbps.
Updating and Upgrading
In this video series we installed the Raspbian Operating System on the Pi from the NOOBS pre-installed on the SD card. Any OS will be updated with constant improvements to performance, security, or the addition of new features. To be sure you’re running the most recent version of the OS, you should periodically run the following two commands on a regular basis – especially if you’re about to attach a new accessory to your Raspberry Pi.
sudo apt-get update
This command downloads the latest version of the OS to your Pi – it may take a while, depending on your network speed.
sudo apt-get upgrade
This command installs the upgraded code (that you just downloaded above) on to your Pi. After you press enter, it will calculate how much space will be required for the new version. It will say something like. . .
After this operation, xxxMB of additional disk space will be used.
