Connecting to Internet

Introduction

Once Ubuntu is installed and running, one of the first things you may want to do is to get an Internet connection up. This may help you with installing software and getting help.

This task is usually very simple, however it requires a minimum of involvement on your part. Of course, you will need to have suscribed to an [http://en.wikipedia.org/wiki/Internet_service_provider Internet Service Provider], and that your Internet connection be installed and functional.

There are several ways to connect to Internet, depending on what type of connection you have, you could have broadband (i.e. ADSL), dialup (i.e. a 56 kbit/s modem) or acces to Internet directly via your Local Area Network for instance.

Go to the following section corresponding to your type of connection.

Broadband

If you have an ADSL or cable modem there are several possibilities, depending on the type of modem.

Ethernet Modem (pppoe)

If your modem connects to your PC with an ethernet network cable you probably want to setup a pppoe conection. However, nowadays many modems also integrate a router, in this case you should follow the instructions provided by the manufacturer, you may find extra help in the Local Area Network section below (if you configure the device via a web interface, it is probably has an integrated router).

In order to setup a pppoe connection, please see [:ADSLPPPoE].

USB modem (UNDER CONSTRUCTION)

This is probably the the most demanding type of modem to set up, USB is far from the ideal medium for network access. If you have a modem that can connect both via USB and ethernet it will be best to use the ethernet connection.

(You may find help for installing a USB modem [http://ubuntuforums.org/showthread.php?p=189972#post189972 here], [http://forum.eagle-usb.org/ here], and [http://eciadsl.flashtux.org/ here].)

Dialup

If you have a dialup connection, a 56 kbit/s or slower modem, you should refer to the [:DialupModemHowto].

Local Area Network

If you cannect to the internet via a Local Area Network (ethernet or wireless for example), the configuration depends entirely on your network.

Configuration information should be provided by your network administrator.

If you connect via a router on a home network, you should read the router's documentation.

You may have to configure the interface through which you conect to use DHCP (dynamic configuration, usualy the default) or specify an IP address, default gateway and DNS server.
