Ethernet is not working after upgrading to 14.04

**rahbz** · August 4th, 2014

Hi,
I have been using dual boot system with 13.10 for a long time, which used to work perfectly fine. Recently I have upgraded it to 14.04. After the upgrade ethernet stopped working (not even detecting).
I have installed latest driver from Realtek manually, even that doesnt seem to work.
Also ethernet is working in windows.

Change the driver via:

Code:

sudo apt-get install --reinstall linux-headers-$(uname -r) linux-headers-generic build-essential dkms
wget http://media.cdn.ubuntu-de.org/forum/attachments/45/14/3005217-r8168-dkms-8.038.00.tar.gz
sudo tar xvf 3005217-r8168-dkms-8.038.00.tar.gz -C /usr/src
sudo dkms add -m r8168-dkms -v 8.038.00
sudo dkms build -m r8168-dkms -v 8.038.00
sudo dkms install -m r8168-dkms -v 8.038.00
sudo depmod -a
sudo update-initramfs -u 
echo "blacklist r8169" | sudo tee -a /etc/modprobe.d/blacklist.conf

Reboot and check:

Code:

locate r8169.ko | grep lib
lspci -nnk | grep -iA2 net
lsmod

The new module is named r8168

Driver still in use is r8169
Since I have added r8169 in blacklist.conf, why did it loaded?

**varunendra** · August 5th, 2014

Before (and if required, After -) installing the suggested driver, may I recommend to try -

Code:

sudo mii-tool -F 100baseTx-FD eth0

Or, in case of error -

Code:

sudo ethtool -s eth0 speed 100 duplex full autoneg off

Not sure if 'ethtool' is installed by default or not on 13.10, but on 14.04, it seems it is.

Recommendation based on this thread.

EDIT:
Apparently I am 12 minutes late. You already tried the proprietary driver. However, both the native and proprietary drivers loading simultaneously doesn't look right. Please show us the blacklist file where you blacklisted the native driver.

**rahbz** · August 5th, 2014

Thanks varunendra, on running the first command ethernet started working.

By doing all this, there is a problem now in windows. I have tried reinstalling driver in windows.
I think adding the r8169 in the blacklist is causing the problem.
Once I remove that line from blacklist.conf , ethernet is working in windows.
