How to Set up a Network in Ubuntu

Last Updated: October 8, 2020

Configuring networks such as a Digital Subscriber Line (DSL) or Asynchronous Digital Subscriber Line (ADSL) primarily used for accessing the internet can be a hassle, especially when you aren't using the same operating system as what the directions were originally written for. This article is a starting point for configuring DSL using Ubuntu Linux.

Steps

1
Open Network Connections to set up network settings in Ubuntu. Go to “System”, “Preferences” and chose “Network Connections."
2
Under the “Wired” tab, click on “Auto eth0” and select “Edit."

3
Click on “IPV4 Settings” tab. Chose the “Automatic (DHCP)” option if your network has a DHCP server. The DHCP Server has automatically assigned the IP address to your system. Click "Apply."
- You also chose the “Manual” option from the Method drop-down list and assign the IP address, netmask and gateway manually. You'll also have to assign the DNS Server address. Click "Apply."
4
Check the IP address settings. Go to “Applications” “Accessories” and chose “Terminal."
5
Type the following command into terminal: “sudo ifconfig” without quotes.
6
Get your new addresses. The Ifconfig command will show the inet address, broadcast address and mask address.

There is no 'option'. You can type in the command and press Enter on your keyboard, and it will run the command.

Warnings

If you are inexperienced with computers, don't do anything that you are not told to do. You can do more harm than good by not following directions provided by technical support, and it could mean that you have to spend more time setting things up for DSL because your box may need to be reset.
