SOLVED. Network problem when dual boot with Windows 8
« on: September 12, 2013, 02:26:40 pm »
On a new machine I have installed Windows 8 and Ubuntu 12.04 but only Windows is connecting to the network.  Ubuntu only shows 'localhost' 127.0.0.1.

I don't know quite what further information you may need.

Has anyone any ideas please?

is this a wired or wireleess connection ?

What do you mean by "network" ? .. a local network, or the internet via your router ?

What exactly only shows "localhost 127.0.0.1" ?

Open a terminal and post the output from:
Code: [Select]
ifconfig
WARNING: You are logged into reality as 'root'

logging in as 'insane' is the only safe option.

Thank you for your reply Mark.

It is a wired network, connected to a router for the internet.

Localhost is shown by 'System Setting/Network'.

ifconfig returns:

lo        Link encap:Local Loopback 
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host

Can you attach the output of:
Code: [Select]
lspci | grep net

Hmm, it doesn't appear to be detecting ANY network adapters.....

Can you make chemicalfan's command read:
Code: [Select]
lspci -vnn | grep -i net
please.

And also send the output from:
Code: [Select]
sudo lshw -C network

Sorry, I always keep the syntax vague and return more than I need... laziness with learning all the switches  :-[

Oddly I actually WANTED more this time .. the "-vnn" will also return the [IDvendor:IDproduct] ID strings, which will hopefully help identify the network adapters

I only threw "-i" into the grep to make "net" case insensitive. :)

Second answer:

02:00.0 Ethernet controller [0200]: Atheros Communications Inc. AR8161 Gigabit Ethernet Controller [1969:1091] (rev 10)

Third answer:

*-network  UNCLAIMED             
       description: Ethernet interface
       product: AR8161 Gigabit Ethernet
       vendor: Atheros Communications Inc.
       Physical id: 0
       version: 10
       width: 64 bits
       clock: 33MHz
       capabilities: pm pciexpress msi msix vpd bus_master cap_list
       configuration: latency=0
       resources: memory:febc000-febfffff ioport:ec00 size=128

I am sorry to take so long with this, but not having the internet on that machine I am having to copy everything the hard way and my eyesight is poor.

The Windows 8 on the same machine does connect to the network/internet.

Thank you again for your help.

OK, this driver (alx) was not included in 12.04 by default, but you can download and install the (backported) package manually.

Can you post the output from running:
Code: [Select]
uname -a
in a terminal ?

Then I'll post a link to the package you need to download and instructions how to install it.

On the Ubuntu computer create a folder on the desktop called network-drivers

on another PC download this file:
http://launchpadlibrarian.net/111339115/linux-backports-modules-cw-3.4-3.2.0-29-generic-pae_3.2.0-29.14_i386.deb

and copy it do the  network-drivers folder you created on the Ubuntu desktop

Now open a terminal and run:
Code: [Select]
cd ~/Desktop/network-drivers
then
Code: [Select]
sudo dpkg -i *.deb

Or just double-click the file to install.

If networking doesn't automatically start working, run:
Code: [Select]
sudo modprobe alx

Once you've done that and you have a working internet connection, it would be a good idea to also run:
Code: [Select]
sudo apt-get install linux-backports-modules-cw-3.4-generic-pae
BEFORE running any updates .. as without that package, a kernel update will break your network again (requiring a different driver).

Once you have both of those installed .. feel free to delete the stuff from your desktop.

Thank you again for your reply.

There's the good news and the bad news.

The good news is that I am sending this from the new machine so the network/internet is all up and running.

The bad news is that your last line of code:

sudo apt-get install linux-backports-modules-cw-3.4-generic-pae

is generating an error:

Couldn't find any package by regex....

OK, do a full system update then reboot .. when you reboot, networking MAY be broken, if it is, post the output from:
Code: [Select]
uname -a
again.

And I'll tell you what to do so it never breaks again :)
