Enable Networking On Trusty Server

Question

I've just done a clean install of Trusty Tahr on one computer and transferred the drive to my actual server (I'm using an old laptop for my server, as it wouldn't/couldn't install and kept dropping to initramfs). I've been having issues with connecting to my network, and I thought the problem was with the hardware, so I tried this:

lshm -c network

Which revealed this:

*-network DISABLED
   description: Ethernet interface
   product: AR8152 v1.1 Fast Ethernet
   vendor: Qualcomm Atheros
   physical id: 0
   bus info: pci@0000:03:00.0
   logical name: p5p1
   version: c1
   serial: 60:eb:69:94:c0:95
   capacity: 100Mbit/s
   width: 64 bits
   clock: 33MHz
   capabilities: (snipped for brevity)
   configuration: (snipped for brevity)
   resources: irq:17 memory:d3400000-d343ffff

How do I 'enable' this adapter?

Answer 1

Figured it out:

(I'm guessing that) since I installed the OS on a different computer than the one it is currently in, the system was configured to use that computers' hardware as the default for 'eth0' (and I can't wait to see what other issues this will cause...)

The solution I used is:

sudo vi /etc/network/interfaces

Delete this:

auto eth0
iface eth0 inet dhcp

And replace with this:

auto (logical name)

iface (logical name) inet dhcp

Next type:

sudo ifup -a

Verify the fix:

sudo lshw -c network

if it no longer says 'disabled' by *- network, then it should be working

Finally, test the fix (I needed to update anyway)

sudo apt-get update
sudo apt-get install (whatever packages you want)

If anyone can tell me how I can configure the logical hardware ID's to the defaults Ubuntu uses, I'd be ever grateful!

This is a solution I have found on this page. Download the file named "compat-wireless-2.6.tar.bz2". 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

Reboot. Test your ethernet connection which should work automatically after reboot. If not, run:

sudo modprobe atl1c

For the wireless to work too you can install additional packages by running:

sudo apt-get install bcmwl-kernel-source
echo wl | sudo tee -a /etc/modules

Use the NetworkManager applet from system tray to connect your wireless devices too.
