How to connect to the internet from Ubuntu

Guys,

I somehow want to start using Linux and I have choosen and installed Ubuntu. But I'm facing some problems when trying to get my Ubuntu installation connect to the internet.

For example, the website from Ubuntu says, (https://help.ubuntu.com/7.04/internet/C/connect-to-internet.html)



1.

Open System → Administration → Networking.
2.

Select the connection you wish to use, then click Properties.
3.

Ensure Enable this connection is turned on.
4.

If your ISP or network administrator has given you an IP address, set Configuration to Static IP address, then enter the address in the IP address field and click OK. Otherwise, set Configuration to DHCP and click OK.
5.

To activate or deactivate network connections, select your connection, then click Activate/Deactivate.


There is nothing like Network (as mentioned in step 1), but Network Tools??

According to the URL you posted, the documentation you are looking at is for version 7.04. The current version of Ubuntu is 8.10. The documentation for networking on that version is here.

Even here (https://help.ubuntu.com/8.10/internet/C/connect.html), it says,

This section shows you how to connect to the Internet and home networks. You will also find troubleshooting guides within the sections.

Lastly, this section also provides a guide to Internet applications.
[Important]

Network Manager is used in many sections of this guide - you can find it:

1.

In System → Administration → Network
2.

In the Notification Area. Its icon resembles two computer screens on top of each other, or a wireless signal indicator if you are connected to a wireless network.

Choose the method you wish to use to connect to the Internet:

1.

Wireless, see the section called “Connect to a wireless network”
2.

ADSL USB modems, see the section called “USB ADSL Modems”
3.

ADSL PPPoE, see the section called “PPPoE Modems”
4.

Dial up modems, see Chapter 5, Modems

Wired ethernet connections should work without configuration, if not then see the section called “Tools to help with network connection problems”.

But I do not see the Network in the path System - Administrator....

That is really strange. You are looking at the menu System in the top right of the screen, then the sub-menu Administration, right? There should be an item named "Network" in that menu.

What kind of network connection do you have? A dialup modem, or an ADSL modem connected via an Ethernet cable? Or wireless? You might want to ask your question on http://ubuntuforums.org/

I'm not able to see the Network, but just the Network Tools. What could be the actual problem?

Woah! A little patience, please. You could answer Jesper's questions to give us a better idea as to what you are trying to accomplish.
Click on System -> About Ubuntu. What does it say there?

It says,

Ubuntu - Linux for Human Beings

Thanks you for your interest in Ubuntu 8.10 - the Intrepid ibex - released in October 2008...

It looks strange and I can see the reason why not many are showing interest in Linux distros!

A quick googling and I found step-by-step instructions for installing ubuntu on your hardware.
It appears that earlier versions had trouble with the wireless driver. Are you trying to configure a wireless or wired network?

Do you mean something might have gone wrong during installation? I do not beleive it!

Finally I gave up my Ubuntu installation and formatted the entire system to reboot my Windows Vista! It's a pity that I was not able to have a dual boot with Ubuntu alongside Vista and do what all I have been doing on my Windows partition.

This is really strange, I have never seen a Linux installation not configure a wired NIC (wireless, yes). Or wait a minute. A while ago my daughter got a fresh-off-the-line ASUS motherboard with a very new wired NIC and neither Fedora nor Ubuntu would recognize it and we had to install an old NIC card in her rig to get it on the network. So I guess it is possible.

Now that you are back on Vista, go into Device Manager have it give you the specs (manufacturer, model, etc) for the NIC and google for Linux help with that NIC.

Also, its a little late now, but did you try opening a terminal and running "sudo ifconfig"? That would at least tell you which NICs it found, if any.

I've heard about a problem in the current version of the Linux kernel used in Ubuntu 8.10 (kernel 2.6.27-11): some wired network adapters don't work anymore because of a bug in the kernel. It has already been fixed and is planned for update 2.6.27-13 (I don't know when it will be available). Note that this does not happen with all network adapters, just a very few specific models.

But even if the problem is that particular bug, then it's strange that you don't see the Network item in the menu.

I've never had luck with getting Linux running on my machine. Earlier I had a Desktop PC and was a total fiasco when trying to get Fedora core 5 running and hooking it up to the internet. Now, the same happened when trying to get Ubuntu on my Lenovo R61.

If you want linux to work NOW, try using VMWare Player and download a pre-installed virtual appliance.
If you want to dual-boot, you've got to be really patient. We haven't scratched the surface as far as network troubleshooting is concerned.
And if you want to get angry, get angry at the hardware manufacturers who don't produce Linux drivers or publish specifications so drivers can be implemented easily. Linux, much like this here ranch, is maintained in large part by volunteers.

I'm using Xubuntu, which is very similar, but not the same as ubuntu.

There you will allways have the Network-applet shown as Icon in the menubar. It's symbolized by two screens, one behind the other. This should show up if an eth-chip is detected (and not switched off in bios), if a wifi is detected, or if a modem is detected. 3 chances.

On the page linux-on-laptops http://www.linux-on-laptops.com/ibm.html I find two different chips for the lenovo R61:
03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN Network Connection (rev 61)
and
03:00.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01)

The command for linux is:


The command to start the network-manager-applet on xubuntu (8.04) is nm-applet , maybe it is the same for ubuntu.
