Ubuntu Ethernet Install

November 20, 2009

sudo ifconfig will give certain into on the ethernet card including an address which is needful.

I could not succeed in getting my Ubuntu machine to connect to the Westell Verizon DSL modem via Ethernet.

One link suggests that I use synaptic manager to install wicd, a GUI network manager, which will DELETE network-manager-gnome and network-manager, so I need to make a careful note of what wicd will DELETE in case I want to reinstall it later.

Wicd is a general-purpose network configuration server which aims
to provide a simple but flexible interface for connecting to networks.
Its features include:
wide variety of settings.
* ability to connect to (and maintain profiles for) both wired and
wireless networks;
* support for many encryption schemes, including WEP, WPA, WPA2 and
custom schemes;
* wireless-tools compatibility;
* tray icon showing network activity and signal strength;
* lack of GNOME dependencies (although it does require GTK+), making it
easy to use in Xfce, Fluxbox, Openbox, Enlightenment, etc.

TODAY I purchased a ethernet card and stuck it in an empty slot. It claims to have a linux driver, but there are no instructions on how to install it. There is already an ethernet card in the Gateway, and I can tell that there are circumstances where it connects to the router, but still no internet.

These are some links that discuss wicd, just for reference but nothing dramatically helpful or encouraging.

There IS ONE sentence in the above link which is encouraging:
Configuration of Wicd is extremely simple, and automatic for wired clients..

I already have Belkin wireless working, and I could live with that, but it BUGS me that I cannot get ethernet DSL working. Yet, I dont want to do something that will lose my Belkin wifi connection. I was relieved to see that I could REMOVE my Belkin from the USB, play around with Wire and USB configurations (which didnt work) and yet plug the Belkin back in and get my internet connection back.

Since I am a little nervous about what this WICD install will do to my pure Ubuntu Gateway, I have decided to try it out first on my old Compaq Presario Wubi Unbuntu install under windows. If THAT gets trashed, it is relatively easy to reinstall and reconfigure the WUBI. Also, the Compaq does have an ethernet card, so Wubi should be able to connect to DSL through that. I will do that WICD install on the Wubi machine right now. I note that WICD in synaptic manager says WIRED AND WIRELESS NETWORK MANAGER.

I marked it for install, and it mentions that it will install python-urwid and remove network-manager and network-manager-gnome. I am hoping that after the install I will still have wifi connection.

It is now prompting me to choose USERS to add to the netdev group, and there is only one, BRYAN, so I check that, and then click FORWARD. The install finished and I still have wifi connection. So far, so good!

I went to system and looked for network manager, and it says it cannot be found because, obviously, those gnome packages were removed. BUT, when I drop down APPLICATIONS, I now see a new option for Wicd Network manager, and it is lit up to indicate that it senses the Belkin wifi. This is a good sign.

When I click on it, the GUI manager comes up and shows ALL the various wifi channels available in my building (all of which are protected) in addition to my own channel.

I checked off the box on my network to say ALWAYS connect to this and exited the GUI. Then I re-entered the GUI, and to my dismay saw that I lost my connection, and that it needs me to re-enter my WEP key. It offers a confusing array of options which I do not fully understand. But the one which finally accepted my WEP and reconnected me was WEP (HEX 0-9/A-F). I also notice that there is a tab where I can define a wired connection to Eth0. The PREFERENCES tab shows me TWO interfaces, wland0 which is WIRELESS, and eth0 which is WIRED. There are two boxes which I check off to 1.) Always show wired interface and 2.) automatically switch to wired interface whenever available. I am working with desktops but obviously, this would be a convenience for anyone with an Ubuntu laptop.

NOW, I shall reboot, and see if I automatically go back into my wireless connection. If THAT works ok, then I shall connect the cable to the Ethernet, and see if it connects automatically.

It is rebooting now. I suddenly realize the tremendous advantabe of having a test Wubi install on one machine, to try things out before you do them on the pure Ubuntu machine (which would take a LOT more work to reinstall).

FIRST, I let the Wubi machine boot into Windows, to see if I still have my wifi connnection in Windows.

YES, wifi still works in the Windows boot.

NOW, I am booting into Wubi Ubuntu. YES, I have my wifi connection. NOW, to plug the cable from the Westell router into the Ethernet card, and see if it automatically switches. The network icon at the upper right of the desktop “launch pad” says “connecting to wired network.” And the the Firefox broswer works.

Next, to UNPLUG the ethernet cable, plug in the Belkin, and see if it automatically senses and switches or if it FREEZES.


The only problem is that when I clicked on the browser, the machine froze. SO, I have unplugged the Belkin USB WIFI adaptor and am booting JUST with the wired ethernet connection.

I first boot into Windows. Obviously the WIFI is not connected. I click on Start => Control Panel => Network, and enable the LAN local area connection. And yes, the browser works on the wired ethernet under windows.

Next to boot into Ubuntu.

Yes, it senses the wired connection, and Firefox works. Next I unplug the ethernet, and it says NOT CONNECTED on the internet icon. Now to plug in the belkin and see if it switches and works, or freezes.

The WCID install went ok on my Gateway, but unfortunately, it cannot recognize the ethernet card on that machine.

Here is the WCID support forum and what looks like an ICQ channel chat.

#wicd on freenode

is a client that works for me under Windows. Join #wicd

I installed ircii in synaptic manager, but it gives no clue as to how to launch it, so then I installed Konversation which is a full gui irc client, and it comes right up, and automatically puts you in a Kubuntu channel.
