## Internet connection settings

The Internet connection settings which are relevant to you will depend on the type and supplier of your Internet connection. Your supplier will generally be able to advise you of the relevant settings if you encounter difficulties in finding them yourself.

If you connect to the Internet using a network or router, see the section called “Network settings” for instructions.

### Dial-up Internet connection

Below is a list of the information which you are likely to need:

- User name

- Password

- Dial-up telephone number

- Modem chipset name

You may also require the following information:

- Dial-out number

- Dialling type (tone or pulse)

- Authentication type

Dial-up modems are poorly supported in Ubuntu. This is because most dial-up modems are designed exclusively for Windows, and so cannot be used on other operating systems.

### Broadband Internet connection

Below is a list of common settings which you are likely to need:

- User name

- Password

- Dialling telephone number

- Connection type (usually PPPoE or PPPoA)

It is possible that you may also require the following technical information, which should be available from your Internet service provider:

Certain USB broadband modems are not supported by default by Ubuntu. If possible, use an Ethernet modem instead.

- IP address and subnet mask

- DNS server, gateway IP address or DHCP server

- VPI/VCI

- MTU

- Encapsulation type

- DHCP settings

### Proxy server settings

If you connect to the Internet through a proxy server, you will need to make a note of some details of the proxy server in order to allow Ubuntu to connect to the Internet.

1. Press Start → Control Panel.

   - If the Control Panel has a purple background, press Network and Internet Connections → Internet Options.

   - If the Control Panel has a white background, press Internet Options.

2. On the Connections tab, press LAN Settings....

3. If the Use a proxy server for your LAN option is ticked, this means that you are connecting to the Internet through a proxy server.

4. Press Advanced... and make a note of the contents of the boxes on the screen which appears. These are your proxy settings.
