This document provides information about configuring systems to connect to networks, the Internet, and other machines on a shared network.

Wired (<acronym>LAN</acronym>)

With <acronym>DHCP</acronym>, settings are automatically configured by the router. Wired network connections are selected as default when they are connected and available.

<acronym>DHCP</acronym> Connections

Most routers use <acronym>DHCP</acronym> to allocate <acronym>IP</acronym> addresses. To connect:

Click the <application>NetworkManager</application> icon in the System Tray.

Under <guilabel>Wired Network</guilabel>, select the name of the network to make a connection.

Static Connections

Instead of <acronym>DHCP</acronym>, a static connection can be configured.

Configure a static connection

<mousebutton>Click</mousebutton> the <guiicon>NetworkManager</guiicon> in the System Tray area and select <guimenuitem>Manage Connections...</guimenuitem>.

Click the <guilabel>Wired</guilabel> tab.

Select the desired connection if it is available and click the <guibutton>Edit...</guibutton> button. If the proper connection is not available, click the <guibutton>Add...</guibutton> button.

Choose <guilabel>Manual</guilabel> option in the <guilabel>Configure</guilabel> drop down under the <guilabel>IP Address</guilabel> tab.

Enter the details and click the <guibutton>OK</guibutton> button.

Click the <guibutton>OK</guibutton> in the main window.

Wireless

In some cases, the wireless network device may need a restricted driver in order to operate. The best way to check this is to open the application named <application>Jockey</application>. To open <application>Jockey</application>, go to <menuchoice><guimenu>Kickoff Application Launcher</guimenu><guisubmenu>Applications</guisubmenu><guisubmenu>System</guisubmenu><guimenuitem>Hardware Deivers</guimenuitem></menuchoice>. If the wireless network device requires a restricted driver, <application>Jockey</application> will provide that information and assist with selecting, installing and activating the proper driver. When this step is completed, wireless connections can be configured. The machine must be rebooted before the newly installed, restricted driver will make the wireless device work.

Connecting to a wireless network

Ensure that the wireless device is turned on. Most modern laptop computers have a physical switch for wireless.

If a connection has been made previouslyto the selected network, connect to that network by clicking on it in the <guilabel>Wireless</guilabel> tab. If no connection has been made to the desired network previously, continue with the following procedure:

Click the <guibutton>Add...</guibutton> button.

Enter the <acronym>SSID</acronym> of the new network. It can be entered manually if known. If not, press the <guibutton>Scan</guibutton> button to search for the network.

Enter any other information required for the connection, especially if the owner has established wireless security for the network.

If the machine has been connected to a wireless network previously, <phrase>Kubuntu</phrase> can automatically connect to the network where it is available. This selection option should be chosen when the initial connection to the network is being configured.

When both wired and wireless network connections are available, the wired connection will be used by default.

Mobile Broadband

<emphasis>Mobile Broadband</emphasis> means any high speed Internet connection that is provided by an external device such as a <acronym>3G</acronym><acronym>USB</acronym> stick or mobile phone with built-in <acronym>HSPA</acronym>, <acronym>UMTS</acronym>, or <acronym>GPRS</acronym> data connection. Some laptops have been offered recently with mobile broadband devices already installed.

Most Mobile Broadband devices should be recognized automatically when they are connected to the computer. If not, <phrase>Kubuntu</phrase> will display a prompt that the device requires configuration.

Configure Mobile Broadband device

Select the <guilabel>Mobile Broadband</guilabel> tab.

<mousebutton>Click</mousebutton> the <guibutton>Add...</guibutton> button.

The <guilabel>New Mobile Broadband Connection</guilabel> Wizard will be displayed. Enter the device and carrier information.

Virtual Private Networks (<acronym>VPN</acronym>)

There are three types of Virtual Private Networks (<acronym>VPN</acronym>) that are currently supported by <application>NetworkManager</application>. It is important to know the type of <acronym>VPN</acronym> network in order to connect to it.

Connecting to a VPN

Begin by installing <ulink url="apt:network-manager-openvpn">network-manager-openvpn</ulink>, <ulink url="apt:network-manager-pptp">network-manager-pptp</ulink>, or <ulink url="apt:network-manager-vpnc">network-manager-vpnc</ulink>, depending on the type of <acronym>VPN</acronym> network.

<mousebutton>Click</mousebutton> the <guiicon>NetworkManager</guiicon> in the System Tray area and select <guimenuitem>Manage Connections...</guimenuitem>

Select the <guilabel>DSL</guilabel> tab.

Configure the <acronym>VPN</acronym> connection.

DSL

Connecting to <acronym>DSL</acronym>

Click the <guilabel>DSL</guilabel> tab.

Click the <guilabel>Add...</guilabel> button.
