I'm having the exact same problem, Internet being painfully unstable and slow. Running Ubuntu 13.10 amd64 and driver r8169 on 1000Mb/s. Just switched from Windows 7, didn't have any problems there.

hit "This bug affects you!", because this bug remains one man bug, and never solved, developers not answer, latest linux kernel 3.14 rc6 have this problem, i never buy any realtek network device, search show this is long years problem and always the same

I have a very similar problem, which I believe may be related. I have the RTL8111/8168/8411. Since I upgraded to 13.10 I'm noticing a drop in network speed. Installing the Realtek driver didn't help, nor other helpfull tips as disabling IPv6. When testing raw network speed from my Ubuntu to my file server I see speeds between 1,1 and 1,5Mb/s.

Other computers reach easily 50-80Mb/s. (als on the same cable). I haven't tested a rollback to 12.04 to check the actual networkspeed with the old version, or tried a clean install. I may do this to check if all other sources for this issue can be excluded.

After spending 15 to 20 hours on this over the weekend, I'm stunned to report that in my case the problem was resolved by switching from CAT 5 to CAT 5e cables, a solution I dismissed as not worth trying when I first came across this suggestion from another 5 hours into my efforts. Here are my setup and symptoms. If anyone's interested in a particular log or report on my setup I'm willing to pass this along.

Bought a new Shuttle DS61 v. 1.1 with dual onboard RTL8111/8168/8411 PCI Express Gigabit Ethernet Controllers. Installed Ubuntu Gnome 14.04. The cables I replaced were only those between my desktop machine and desktop router (D-Link DIR 655), but I believe I'm running Cat 5e (or 6) from inside the wall to my Netgear internet router. (I'd been working with Ubuntu 12.04 on my laptop from this same location using the same cabling and routers for a wired connection for more than 6 months, without incident or problem.)

Didn't really notice any latency until I ran an update a day or two after my initial set up and noticed that the packages were lagging and some erroring out. But, merely inspecting the “edit connections” in Ubuntu, particularly the DHCP setting, resulted in a prompt completion of the update session, in the manner I've come to expect on my other Ubuntu based machines.

But, the problem persisted. My internet access was very slow, and at times reported no connection. Pinging addresses of other machines on my intranet showed the lan ports were working just fine for this purpose, just over 0.2 ms per attempt with no packet loss and no intermittent slowing. (I'm working on a website that's currently hosted internally and I had this automatically booting in a browser tab with another browser tab pointing to an external site throughout the many reboot attempts involved in working on this problem. The internal site typically came up promptly and seconds faster than the external site (which was google.com).) Pinging sites on the internet resulted in times of 1500 or greater and, on at least two test attempts, all packets were loss. This corresponded to my visual experience using my web based mail server. Lots of “still sending” instances and sporadic loss of connection.

I tried various fixes reported by others as resolving what seemed like the same or similar slow performance of the RTL 8111/8168 lan ports (e.g., changed the driver from r8169 to r8168, disabled IPv6, assigned static IP ports – I thought it was an internal network problem for a while – and a half dozen or more other suggestions I came across in my searches, and, for what it's worth, I'm still running the r8168 module under the “it ain't broke” theory). It was only after signing up for email on this bug report that I decided to switch the existing CAT 5 cables between these lanports and the Dlink. Plugging in the first of the 5e cables resulted in immediate resolution of the internet connection problem (I even noticed the activity lights on the lanport flickering more quickly on the one with the 5e than the one without). It's been up and running fabulously for about 48 hours so, with no small amount of trepidation, I'm calling my particular iteration of this problem s...

Further to #27 - So much for resolution. Browser speed is still terrific since switching to 5e cables, but I'd forgotten I'd disabled the HD Audio in the BIOS very early on in the hunt for a solution to the ethernet speed problem. A couple of hours ago I noticed no sound and re-enabled the HD Audio only to receive the same dismal ethernet speeds reported earlier. Disable the HD Audio in the BIOS, and ethernet performs like a champ. HD Audio was disabled through most of the adventures I had this past weekend so I still thing there's something to the 5e cabling. Sorry if this misled anyone.

my motherboard MSI H81M-P33, just update bios from version 1.0 to version 1.4, download from official http://www.msi.com/product/mb/H81MP33.html#/?div=BIOS, network work normal, but, i think test couple days and report there :-). ethernet driver standard r8169, also work with r8168 from realtek site.

unzip driver archive 7817v14.zip, copy to usb file E7817IMS.140 and update from bios through MFlash menu, choose "BIOS + ME".

update bios not help, bug remain, noticed total loss of the error that after updating the BIOS, change the driver, this only works the first time until shutdown computer, THIS IS MAGIC!!!!

Since I upgraded ubuntu 14.04 from kernel 3.11 to kernel 3.13, I have lost my ethernet connection.
Reading the various forum, it seems there is something wrong with the macros _devinit and _devexit . But I am no expert.

3.11 kernel used in ubuntu 13.10, tested - have bug

log show error:

For now have another network card tp-link, issue the same, this is not driver, kernel even not use r8169 (or r8168) - lsmod | grep r81 - none. Because connected through router (netgear jwnr2000v2), but from windows is work fine, linux not. Direct cable connection work perfect.

another one here.
made ubuntu forum post here asking others to test LAN speed:
http://ubuntuforums.org/showthread.php?t=2245203

killing lightgm resolves the problem and speed jumps to 12mb/s . But once back in GUI, problem returns.

Tested using Netcat and iperf, LAN speeds peek out at 1.2MB/s

Updating driver does not help.

if someone use router, try turnoff IGMP option, restart router, turnon IGMP option (needed), maybe is router bug, but is known problem "MTU black hole" when in network path someone turn off IGMP and packets are lost, this is why some sites open, some not

after router update, make router reset, confiture router and all work perfect, is router bug

Same bug for me on linux the speed is 10Mb/s except that on Windows 8 (dual boot) the speed of the link is 100Mb/s.

What I did :
1/ change the module for the realtek module -> no change
2/ try the ethtool -s speed -> cannot advertise
3/ change the ethernet cord between my laptop and the wall -> immediatly the speed switchs to 100Mb/s (with the actual module realtek, I didn't reverse) . I did that many time to see the result : with one cord : 10Mb/s ; with the other one : 100Mb/s
this behavior is strange as it seems to me that on same laptop on windows 8 the speed anyway is 100Mb/s

oups !
I made a mistake : the behaviour on Windows 8 is the same : with one cord there is an erratic speed (sometime 10 , sometime 100, most often 10) with the new one the speed is 100Mb/s.

Is the dirver r8169 bug still persisting? On the realtek site the solution is to run the script: 'autorun.sh' and switch to the r8168 driver.
