LAN doesn't work under Ubuntu 8.10 on Atom Mainboard


Hi,

Can anyone offer any help please I'm having the same problems with Ubuntu 8.10 installed on a D945GCLF mainboard.

Tried the following but 'eth0' doesn't appear at all now:-
http://ubuntuforums.org/showpost.php...10&postcount=6

LAN was working okay prior to installing updates after a fresh install however once rebooted LAN is disconnected.

Am a complete newbie to Linux therefore would appreciate a step by step guide on how to get back up and running again.

Thank you.

Check the output of lspci, lsmod and ifconfig. lspci will show if your Ethernet NIC if being detected on boot. lsmod lists all modules that are loaded. It's a long list, so see if you can find any sign of the Ethernet driver, whatever it is.

If the card is listed in lspci, but you don't find the module, you can try "modprobe driver_name", using whatever driver it should be. You'll have to figure that out.

Then check ifconfig again.

Was there a kernel upgrade in this Ubuntu upgrade?

Open a terminal and type: lspci and post the results here. Type ifconfig and post those results also.

Hi Nexus, Thank you for your reply. Here's what was obtained from lspci and ifconfig:-

lspci:-

00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01)
01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)



ifconfig:-

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:6 errors:0 dropped:0 overruns:0 frame:0
TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:376 (376.0 B) TX bytes:376 (376.0 B)

Think that the Ethernet controller is being detected upon booting up however it's no longer working since fresh-install. Tried this twice now as well. Same problem on both occasions. Understand that there is a driver issue and that another driver can be used however that's where I've got stuck (providing barking up the right tree). Any suggestions would be appreciated.

As suggested by pentode can you do lsmod and check for any reference to your Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E.

Cannot find anything here referring to LAN or Ethernet. Recall reading on a command that was entered earlier that the LAN reported as being disabled however cannot remember what the command was.

Was there a kernel upgrade in this Ubuntu upgrade?
Hi Pentode,

Am not 100% certain whether a kernel upgrade was included. How can I go about checking what kernel is installed please? (in newbie terms).

Thank you.

Check System--> Preferences--> Network Configuration, to see if you can activate your lan port.

When authorising updates, it pays to have a look through the proposed updates before applying. To check what kernel you are running now type: uname -r

Hi, Good point. I'd taken the updates for granted as I understand that they're from Canonical however am new to all of this therefore shouldn't assume that the source for the updates is legitimate. Shall report back here what kernel is running.

Looks like a possible bug in Ubuntu update?:

https://bugs.launchpad.net/ubuntu/+s...ux/+bug/326891

This Ubuntu upgrade seems to be breaking a few things.

Just checked, it's running:-
2.6.27-11-generic

Fresh install required / recommended?

Thank you.

Thank you for that. Sounds like this could be down to a bug. Understand that there were problems with previous releases of Ubuntu. Guess the fixes that are posted on various sites (which haven't worked very successfully / at all unfortunately) are referring to pre-8.01 releases. The fix was possibly included in the installed version however the updates have broken the fix?

Think that a fresh install is required unless this is not absolutely necessary and either you or Nexus can give any other suggestions (downgrading the kernel?).

Edit:

Since posting the above I've read over the link that Pentode has kindly provided and now understand that there's a v2 release of the same kernel that should fix LAN issues. Could you please advise how to go about installing the new kernel?

Thank you again.
