Ubuntu 12.04 and RTL 8211CL not working

**varunendra** · October 30th, 2013

The major difference is the kernel and respectively the driver version.

Also, this may be significant -

The lshw shows it is on a PCI bus -

It also shows it is "bridged", but what is it bridged to? Does this motherboard have two onboard interfaces?

Please check -

Code:

lspci -nnk | grep -iA3 net

Does it show the ethernet interface?

And I would strongly recommend to try a Live CD of 12.04.3 as it uses kernel 3.8, and hopefully, a much better driver.

Alternatively, you may choose to upgrade the current installation to the latest kernel, along with latest supported hardware enablement stack. But trying 12.04.3 in live mode is a much safer option.

Hi varunendra,

I try what you said and nothing...

sudo lspci -nnk | grep -iA3 net

Code:

00:07.0 Bridge [0680]: NVIDIA Corporation MCP61 Ethernet [10de:03ef] (rev a2)
    Subsystem: ASRock Incorporation 939NF6G-VSTA Board [1849:03ef]
    Kernel driver in use: forcedeth
    Kernel modules: forcedeth

About live CD, I tested both versions 32b and 64b for 12.04.3 in live mode, and network problem didnt change.

I bought this machine a month ago and I can't use it yet. Also there is another issue with power, it do not shutdown or restart by it self, I have to press the buttons for both actions.

About motherbiard as far as I know it only has one interface.

Anyway thanks again for your time and advice.

Apparently, you added the "it only has one interface" part one day later, which now makes me even more confused.

Its PCI bus address (0680) is strange for me and the mode "Bridged" is mysterious. The driver "forcedeth" is not very uncommon though, so you shouldn't be out of luck yet.

Unfortunately, as late as I am replying to this (and that too after being reminded by PM..), I may get even busier for next few days. So I'm not sure when (and if) I'd be able to dig up and post something meaningful, I'm not very good with ethernet issues anyway.

I don't have any experience with such 'bridged' interface, and am absolutely clueless at this point. Sooo.. I'm posting this just as a BUMP, and a CALL FOR HELP !! Anyone reading this post, please jump in if you have any ideas to share with us.

Please check the module parameters:

Code:

echo "options forcedeth msi=0 msix=0" | sudo tee -a /etc/modprobe.d/forcedeth.conf

Reboot and reset the BIOS to default. Check the outputs again

Hi praseodym, thanks for reply!!!..

Well I was a bit busy this days, but finally I did try your advice..., the first thing is that forcedeth.conf wasnt created yet, I run your command and did a BIOS reset...

Not connection yet... now, what are the outputs that I need to recheck???

Many thanks in advance.

Lets have a look at

Code:

lsmod
ifconfig -a
cat /etc/resolv.conf
cat /etc/network/interfaces
route -n
dmesg | egrep 'eth|force'
cat /var/lib/NetworkManager/NetworkManager.state
cat /etc/NetworkManager/NetworkManager.conf
