RTL8111/RTL8168 Network Connection Fix

[praseodym]

Try it with:

sudo make
sudo cp src/r8168.ko /lib/modules/$(uname -r)/kernel/drivers/net/
sudo depmod -a
sudo modprobe -v r8168

Installed 3.1.2 kernel and connection is stable with 8169 driver. One problem does however remain using the 8169 driver, can't get gigabit working, only 100 mbps.

I'm trying to fix this 8169/8168 issue on my system, which was running fine until the 11.10 upgrade. I followed ratcheer's post (thanks) from a few days ago and verified via lspci that r8168 is in use by the network interfaces after rebooting.

I use a static IP on eth0. After rebooting, Ubuntu says eth0 has an established connection (and the info appears correct), but I cannot ping google.com, my gateway, or other machines on my network.

If I switch to DHCP I can then ping google.com, but still cannot ping local machines or my gateway.

Thanks for any help. I rely on this machine for Samba shares and this is really becoming a problem. I added a few bits of info below, let me know if you need something else. Thanks.

My laptop can now go to sleep and wake up without losing the network connection.

That thread seems only to address people using the 3.x Debian kernel. I got this problem on Ubuntu 11.04, which uses the 2.6.x kernel. So even though I read through it in some detail, I came away doubting whether any of the information there would actually help me.

BUT I have good news! For those of us still using the 2.4.x or 2.6.x kernels, Realtec just released a driver update. Version 8.027.00 installed successfully on my system, and I finally have a network connection again.

Thanks, ladasky.

The old r8168 has been working fine, for me. I wonder if I should gamble on the new one? I would hope that if the new one gave problems, I could just reinstall the older one, but you never know.

Driver version 027 does also compile against kernel 3.0.x (Oneiric), but still not with kernel 3.2 (Precise)

The new module version works, too. Thanks, again.

Actually, kernel 3.2 should work with the standard supplied driver, r8169. At least, it works for me on Arch Linux with the newer kernels.

I find that the r8169 driver in the 3.2 kernel (Ubuntu 12.04 alpha 1+) works once the connection is established which can take anywhere from 10 seconds to 5 minutes to occur. A fast boot is somewhat meaningless if it takes several more minutes to connect.
