Welcome to the forums raiden2332!

It seems you are connected via wireless. So is the problem only with the Ethernet port as your thread title suggests? Some description of the problem is always good.

If it is indeed just the Ethernet, please tell us what all you have tried so far to fix it.

Have you checked the cable? Tried replacing it with a different, working one?

On software front, initially you may try this -

1) Install 'ethtool' -

sudo apt-get install ethtool

2) Try forcing 100 Mbps/full-duplex mode using ethtool -

sudo ethtool -s eth0 speed 100 duplex full autoneg off

This change will be temporary, will be lost at next boot, so try the connection without rebooting after running the above command.

If it doesn't help, please post the details of the problem and whatever you have tried so far, along with the output of -

sudo ethtool eth0

While posting the outputs, please use 'Code' tags. It preserves the output's formatting and makes the post cleaner, compact and more readable. To see a quick 'HowTo' with screenshots, please follow the "Use Code Tags" link in my signature.

thanks for the answers in the german forum there is the solution

Thanks for sharing the solution! Please mark the thread as [SOLVED] (using "Thread Tools" link above the top post) to make the thread more helpful to others. Thanks!

Hello, thank You!.
I had recently the same problem using Asrock J1900-ITX board and Trusty.
It WAS perfect until some recent update, around a day or a few days ago.

Using gigabil lan I know my file sharing DID run at cca 100MB/s (not megabit, real file transfer in megabytes).
I noticed today (8/7/14), that vnc connect is very poor, pausing.. But no link down or any other signs.
At first I did fight with pstate powertop and so,.. Well at last I came here, and the solution worked perfectly.
I woud bet that new kernel is suspect:
Linux xxxx 3.13.0-30-generic #55-Ubuntu SMP Fri Jul 4 21:40:53 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Just a note - do not try that steps using VNC or so at a distant machine, as it breaks the link after modprobe -r
And do not panic when nothing changes after service restart command, my machine started normal link only past real reboot.

btw, before applying this solution, IPerf results was cca 57kilobites, up to 100kbit/s, instead of cca 940 that is normal.
I think some internet-only users would think their internet provider went poor, instead of real reason of damaged drivers.

it works like a charms
Thank you

The dkms 8.038 changelog lists "Use module aliases for PCI IDs supported by r8168 instead of blacklisting r8169. (Closes: #739394)".

Instead of:

echo "blacklist r8169" | sudo tee -a /etc/modprobe.d/blacklist-r8169.conf

You might want to:

echo "# map the specific PCI IDs instead of blacklisting the whole r8169 module" | sudo tee -a /etc/modprobe.d/r8168-dkms.conf
echo -e "alias\tpci:v00001186d00004300sv00001186sd00004B10bc*sc*i*\tr8168" | sudo tee -a /etc/modprobe.d/r8168-dkms.conf
echo -e "alias\tpci:v000010ECd00008168sv*sd*bc*sc*i*\t\t\tr8168" | sudo tee -a /etc/modprobe.d/r8168-dkms.conf

And for the users of Ubuntu without network manager, instead of: "sudo service network-manager restart" you can use

ifconfig p5p1 down;ifconfig p5p1 up

.

wget http://ftp.de.debian.org/debian/pool...8.00-1_all.deb

This returned a 404 error Not Found.

DOes this solution need an update?

thanks for the answers in the german forum there is the solution

sudo apt-get install linux-headers-generic build-essential dkms
wget http://ftp.de.debian.org/debian/pool/main/r/r8168/r8168-dkms_8.038.00-1_all.deb
sudo dpkg -i r8168*.deb
echo "blacklist r8169" | sudo tee -a /etc/modprobe.d/blacklist-r8169.conf
sudo modprobe -rfv r8169
sudo modprobe -v r8168
sudo service network-manager restart

The ftp-link is down. I changed it and used this instead:

sudo apt-get install linux-headers-generic build-essential dkms
wget http://launchpadlibrarian.net/173890469/r8168-dkms_8.038.00-1_all.deb
sudo dpkg -i r8168*.deb
echo "blacklist r8169" | sudo tee -a /etc/modprobe.d/blacklist-r8169.conf
sudo modprobe -rfv r8169
sudo modprobe -v r8168
sudo service network-manager restart

For some reason the four last lines didn't execute so I ran them again separately.

Then I got a wired connection in the network manager but internet didn't work.
Then I did what MariusMatutiae suggestes in this thread, now everything works!

Check the version of xxx.deb and change it if necessary
