Network is not working nicely with RTL-8110SC/8169SC

Question

Well, I've got a wired network on my Ubuntu 11.10 fresh installation. I can download files and surf the Internet. The problem is that sometimes it takes a long time to load websites and sometimes it gives up trying. I also unsuccessfully tried to connect to an FTP server using Filezilla. The same wired network does work fine in a dual-boot installation of Windows 7.

How can I configure my network appropriately.

SOME INFO:

please have a look at this question and add some details of your hardware and some logs to your question. http://askubuntu.com/questions/14008/i-have-a-hardware-detection-problem-what-logs-do-i-need-to-look-into — fossfreedom, Oct 27 '11 at 14:00
Could tell if your wired connection "auto configured" or if you manually set it up? — lpanebr, Oct 27 '11 at 13:56
It was auto configured. As I said, it does work, but not as well as it is supposed to. — Paulo Lieuthier, Oct 27 '11 at 14:20

Maybe the kernel driver r8169 kernel is not good enough. Try compiling the ralink drivers:

Make a backup of your driver first. To find where the driver is:
```
find /lib/modules/$(uname -r) -name r8169.ko
```
copy the driver somewhere in your home directory.
Download the drivers here (select US1 server as the other two don't work)

Prepare the system for compiling:

sudo apt-get install build-essential linux-headers-$(uname -r) linux-source

Check whether the built-in driver, r8169.ko, is loaded.
```
lsmod | grep r8169
```
If it is installed, please remove it.
```
sudo modprobe -r r8169
```

compile the driver:

tar jxvf r8169-6.015.00.tar.bz2 # unpack this on th desktop
sudo mv r8169-6.015.00 /usr/src # move the drive directory from desktop to /usr/src
sudo -i

navigate to /usr/src/r8169-6.015.00 and run

make clean modules          
make install
depmod -a
modprobe r8169

drop privileges:

exit

You can check whether the driver is loaded by using these commands:
```
lsmod | grep r8169      
ifconfig -a
```
Reboot and check again that the driver is loaded. If it isn't, You might want to add r8169 to the list of modules which are loaded on startup. Edit this file:
```
sudo nano /etc/modules
```
add the line
```
r8169
```
save, exit, and reboot

If something goes wrong or you want to revert this procedure, just restore the file that you backed up in the first step to its original location.

I'm curious if you resolved this as i am having what i think is the same issue... network works fine for a moment, then will not respond at all for several minutes. active connections seem to be ok since i downloaded source code for several hours without fail, but new connections seem to be the problem and only sometimes.

UPDATE: disabling ipv6 didnt work for me. My solution for now was to install a spare Netgear 10/100 NIC in my motherboard until someone else fixes the realtek driver.

I have not tried hhlp's answer, but I needed this thing running ASAP so for now the spare card works great!

i have an integreated Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06) – Jason Nov 06 '11 at 14:05
i tried hhlp's instructions and it worked. I can't bump up his answer though... I had to download a different driver for my different adapter of course. – Jason Nov 11 '11 at 23:51

Try to disable IPv6 if you are not using it.
