View Full Version : [ubuntu] Configuring an Internet Connection

July 23rd, 2008, 03:54 AM
So recently Windows crashed on my HP notebook and Im using a CD that I previously installed Ubuntu on. Im in the demo mode, so I havent actually created a partition on the hard drive and installed the OS on it. Im trying to connect to the wireless network we have running but the card (Broadcom B43) doesnt work with Ubuntu. The solution (http://penkin.wordpress.com/2008/03/28/ubuntu-804-broadcom-wireless/) Ive found requires me to access the internet, which Im assuming is through a wired connection. I have the laptop directly wired to the internet but I dont know how to configure it. Anybody have any clue how to get me where I want to go with this

Open a terminal, type ifconfig. That should give you a list of network interfaces. Figure out which one is your wired connection, then type sudo ifup interface_name.

If that doesn't work, tell us the output.

Note that the wireless solution you linked to will probably require you to actually install Ubuntu first.

If eth0 is the designation of your card, and say your router is giving your PC an IP address of then try:

sudo ifconfig eth0 netmask up

then maybe, restart the network

sudo /etc/init.d/networking restart

The Networking and Wireless forum has a nice howto stickied on manually setting up a network.
