Wired ethernet not getting detected

[pytheas22]

No, just typing
Code:

sudo ifconfig eth0 up

didn't worked with the Network Manager applet - I still had to type
Code:

sudo dhclient eth0

to get the wired connection.

Thanks for that information. To create a script that will run those two commands automatically whenever your computer boots, type these commands:

sudo -s
gedit /etc/init.d/eth0-up.sh

A file will open. Paste these lines into it:

#!/bin/bash

ifconfig eth0 up
dhclient eth0

Then save and close the file, and finish by typing:

chmod +x eth0-up.sh
update-rc.d eth0-up.sh defaults

Now the commands that you need to get the ethernet working should be run automatically each time your computer boots. Let me know if you have trouble.

Hello,

Yesterday I installed Ubuntu on my Acer Aspire 4820TG and that completed without errors. Then I was checking my wireless, and it did not find any. I have looked in this thread, and that helped a little.

Like I said, I don't have wireless-connection, and therefor I need to install my wireless driver offline. I have placed b43-fwcutter in the right map, and in "Admin -> Synaptic Package Manager -> Settings -> Repositories" I have checked the "Restricted copyright" on the bottom og that site.

Then I can go into "Hardware Drivers" and there I find one driver: "Broadcom STA wireles driver". Thats probably the one I have to install. When I click "Activate" I got an error:

Failed to fetch cdrom:[Ubuntu 10.04.1 LTS_Lucid 
Lynx_ - Release amd64  (20100816)]/pool/main/p/
patch/patch_2.6-2ubuntu1_amd64.deb File not found.

How can I fix this?

Thanks for answers!

[pytheas22]

NetGeir: the driver you need should be on the Ubuntu installation CD (assuming you used a CD to install). You first need to enable your CD as a software repository, then try installing the driver again by clicking "Activate" in Hardware Drivers. If you have trouble, please let me know.

Thanks to all,
With this Forum i resolved my Ethernet problem with "Etheros Communications AR8152 v1.1 Ethernet(rev c1)" in Ubuntu
With the help a mobile broadband connection we got all the dependencies by following this process.

Thanks a lot again.

Your ethernet hardware seems to be quite new and doesn't have a driver built into Ubuntu as of yet. However, there's a driver included in the compat-wireless stack that you can use (I have no idea why they included an ethernet driver in compat-wireless, but according to these emails, someone did).

To download, compile and install the driver, first go to http://linuxwireless.org/download/compat-wireless-2.6 and download the file named "compat-wireless-2.6.tar.bz2" (you can't download it in the terminal because of anti-hotlinking). Save it to your desktop. Then run these commands:

sudo apt-get update
sudo apt-get install build-essential
cd ~/Desktop
tar -xjvf compat-wireless-2.6.tar.bz2
cd compat-wireless*
scripts/driver-select atl1c
make
sudo make install

Then reboot. Hopefully your ethernet will work automatically after reboot; if not, run:

sudo modprobe atl1c

to insert the driver. Let me know how it goes.

We can probably make your wireless work too, if you're interested.

HI all

[NetGeir]

pytheas22: That's what I did, maybe I didn't explane it god enought. And when I do that, I get the error like i sayd:

Failed to fetch cdrom:[Ubuntu 10.04.1 LTS_Lucid 
Lynx_ - Release amd64  (20100816)]/pool/main/p/
patch/patch_2.6-2ubuntu1_amd64.deb File not found.

The installations CD is in, but the files can't be found.

If you want me to check some code in terminal, just let me know.

[pytheas22]

NetGeir: ah, I understand now. That is a bit strange. If you open up your CD to browse the files, can you navigate to the folder ...pool/main/p/patch/? Do you see a file there named patch_2.6-2ubuntu1_amd64.deb and if so can you install it by double-clicking?

If that works, try also going to ...pool/main/g and installing the gcc package, and ...pool/main/m and installing make. Then, go to ...pool/restricted/b and look for packages whose names begin with "bcmwl" and install them.

If this all works, it will get the wireless driver installed for you automatically. If it fails, however, let me know and we'll see about installing it a different way. In that case, it would be helpful to know the output of:

uname -a
lshw -C Network
lspci -nn

[NetGeir]

Hi again,

patch_2.6-2ubuntu1_amd64.deb was finish without errors:


I find every file in the folders exept the "make".

When I try to install the gcc package it say that it could not install booth of the files. I guess thats because Ubuntu is looking for the second file on the internet, and not in the folder the other file are in:



Here is the output of the code:

[pytheas22]

NetGeir: can you find the packages 'fakeroot' or 'dkms' on your CD as well? They should be there, I think. If you install them, you should then be able to install 'gcc' without it having to download packages from the Internet.

If this doesn't work, let me know and we can try to get the driver installed another way, but it will be tricky.

[NetGeir]

Fakeroot and dkms has been installed, but when I try to install gcc, I get the same error. It will not install the second file from the folder, but it will try to install it from the network:



I will try anything to get the network, 'cause I really like Ubuntu. Thank you for helping me.

[pytheas22]

NetGeir: I'm not sure why that's happening when you try to install gcc, but let's try a different strategy. I compiled an ethernet driver that should work on your system, using the source code from http://partner.atheros.com/Drivers.aspx. To install it, first download the file http://burnthesorbonne.com/files/AR81.tar.gz and transfer it to your Ubuntu computer. Save it on the desktop there. Then run these commands (if this doesn't work as expected, please post all output so I can see what might have gone wrong):

cd ~/Desktop
tar -xzvf AR81.tar.gz
cd AR81
sudo cp src/atl1e.ko /lib/modules/2.6.32-24-generic/kernel/drivers/net/atl1e/
sudo insmod /lib/modules/2.6.32-24-generic/kernel/drivers/net/atl1e/atl1e.ko
sudo ifconfig eth0 up

At this point, your ethernet should work and you should be able to connect if you plug it in. If you get this far, you should then be able to get the wireless to work by running:

sudo apt-get update
sudo apt-get install bcmwl-kernel-source bcmwl-modaliases

It will be able to download the files it needs from the Internet, since wacky things seem to be happening with the CD.

Let me know how this goes. If the ethernet doesn't work, please post the output of all of the commands from the first set above, along with:

dmesg | grep -e atl -e eth
lshw -C Network
lsmod | grep atl
