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 <keycombo><keycap>Alt</keycap><keycap>Space</keycap></keycombo>. This will open up a pop-up called <application>Katapult</application>. Enter the word <userinput>konsole</userinput> and press <keycap>Enter</keycap>. You will notice that once <application>Konsole</application> opens, you will see something similar to <prompt>username@hostname:~$</prompt>. Here you will type <userinput>lspci</userinput> and press <keycap>Enter</keycap>. Locate your network hardware information, you will need this for the upcoming sections, especially for wireless cards.

No matter the connection you are using, the network settings will usually be configured the same. Most users are probably familiar with Windows networking and seeing terms such as <acronym>IP</acronym> address, gateway address, netmask address, and <acronym>DNS</acronym> addresses. They are still the same in Kubuntu however there are two extra settings that are common with Linux systems, network address and broadcast address however these extra settings are not necessary for basic home networking and connecting to the Internet.

# eth1 is setting its own address (static)
auto eth1
iface eth1 inet static

netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.0.255
gateway 192.168.1.1

A gateway address is also known as the default gateway. The gateway serves as an access point to another network and a majority of the times would be your service provider in order to gain access to the Internet. A gateway <acronym>IP</acronym> address looks the same as an <acronym>IP</acronym> address.

<acronym>DNS</acronym> (Domain Name System) translates domain names as well as computer hostnames to <acronym>IP</acronym> addresses. This is the system that will translate www.kubuntu.org into the websites actual <acronym>IP</acronym> address.

Establishing a connection

42.

Establishing a connection depends on various things. Are you connecting directly to the Internet utilizing a modem whether it be a <acronym>DSL</acronym> modem or a dial-up modem? Do you have broadband access and have a router or a system providing Internet sharing? Are you using Ethernet or wireless network connection? <acronym>DHCP</acronym> or static? These are just a few of the variables that need to be researched and understood prior to moving on and possibly causing more problems now or later on.
