11.10 wired network problem

[jaybutts]

I had this same problem and found out this is ongoing. I started to make a fix script for this in thread: http://ubuntuforums.org/showthread.php?t=1947993

Further to my posting of #36, I should say that each time I update the kernel, I have to run the commands again.

There's no problem doing this, but I am hoping that this issue will be resolved with Ubuntu 12.04.

But in case it isn't, I'll set up my commands as a script.

On my system, the standard r8169 driver is working in 12.04 (3.2 Linux kernel).

I have had this problem for months if not years with varying degrees of annoyance. Sometimes i was able to fix after spending hours messing about, but this would fail after a new kernal upgrade.

I have been messing around this morning, and decided to re-install Ubuntu to the latest version, and lo and behold it appears to be sorted. I installed my updates after the re-install and the wired connection is still all good, using the r8169 driver. This is great news!!

Thanks to all those people who contributed to this thread hopefully it went some way to the eventual fix.

If anyone has an explanation as to how this was fixed please post.

Hi, first we do not know if you have the right ethernet card for this procedure, as the previous post stated please post the results of this command to determine if it might help.

lspci -nnk | grep -iA2 net

It looks like you have two install programs running at the same time and you can only have one, you need to close software center while you are working with the terminal and vice versa.

When you enter a command with sudo in front of it you need to enter your user password, and it will not show the password as you type it for security reasons so when you are done hit enter and the command should run and it may not show anything on the screen many commands do not.

Unblacklist the driver, you can use a very basic method. Just open the blacklist.conf file in super-user mode:

gksu gedit /etc/modprobe.d/blacklist.conf

and add the hash (#) mark in the beginning of any line which you want to enable. So in your case, after opening that file with above command, look for the line that says blacklist r8169 (it would most probably be in the last) and add the '#' mark in its beginning. So now it should look like this:

# blacklist r8169

Only do this if that driver is in the blacklist file, if not post the results of the command before you do anything please.
Save and Exit.

Then

sudo modprobe r8169

and your connection should work hopefully.
Thank you

I have a simular issue. I'm not sure what happened. Ubuntu had worked well for me the last 6 months.

lspci -nnk | grep -iA2 net

Could someone 'please' help with similar issue. 10.04 with onboard LAN. Emachines W3650 with (I think) the RTL8100c onboard LAN. Further details at this thread:

Mine might be semi-related, I can connect and everything goes pretty smoothly i just get PAINFULLY slow speeds. There's my wireless card, anyone know what's up?

my situration is kind of weird. One ubuntu boot (webserver) completely no LAN card responce, however this boot...On the same box, I get a LAN card signal.

What I probably should do, is download to this boot (image)? Then move the solution on page one to the webserver image since I have no internet connection at all with the webserver.

I've had problems similar to those described here with my Asus Sabertooth motherboard and its "Realtek RTL8111/8168B PCI Express Gigabit Ethernet controller"

When I have seen problems with an intermittent network connection, it's very easy to watch what's happening by opening a terminal and typing:

ping example.com

One can thus see how it loses its connection and reestablishes it, repeatedly.

The simple solution that I discovered was using the Linux driver which is provided by Realtek, itself here. I use the latest one listed (intended for kernel 2.6.x). You simply download it and run autorun.sh as the superuser, and everything is smooth sailing from then on out.

In the last day or two, I received the kernel update from 3.0.0-12 to 3.0.0-17 and it seems to me that it may have caused me to need to reinstall this Realtek network driver.
