Introduction to networking in Kubuntu

Networking in Kubuntu has gotten much easier for everyone. The days of configuring your settings via the command line are almost gone completely. A majority of users will never have to use the command line when configuring their network settings in order to share files between PCs or to gain access to the Internet. There are those select few who might be utilizing hardware that is not Linux certified as of yet. For those, there might be the possibility of making changes via the command line.

KNetworkManager makes connecting and managing your connections a snap. Whether you are using a wired (Ethernet) connection or a wireless connection, KNetworkManager can monitor for connects and disconnects, locates wireless access points, and manages your wireless encryption (see the section called “KNetworkManager”).

Some users will want to do more than surf the Internet or read Email such as sharing files between a Windows PC or a Mac. Setting up Kubuntu on a Windows network is a very simple task and at most will only require very minor command line usage.

Determining your network hardware

If you are having issues connecting to your network or the Internet, the first thing you need to do is locate the model of the network device you are using. To do so, unfortunately you will have to use the command line at this time. To get to the command line in Kubuntu, press Alt-F2. This will open up a pop-up called KRunner. Enter the word konsole and press Enter. You will notice that once Konsole opens, you will see something similar to username@hostname:~$. Here you will type lspci and press Enter. Locate your network hardware information, you will need this for the upcoming sections, especially for wireless cards.
