No Wired Internet Connection in 8.10

[Conrad Theart]

Binary package hint: network-manager

I have a Dell Latitude D630 laptop running Ubuntu 8.10. When I was running 8.04 I had no problem connecting to the internet via my work's ADSL line. I just plugged it in and that was it. My laptop has a internal 3G card and since 8.10 it is a dream to connect via 3G, but not with ADSL. When I plug it in the network manager starts doing it's thing, and then says it is connected to "auto eth0" but I can not ping the router, Google, or anything. I've tried to get help in forums and in #ubuntu, but couldn't get it sorted out. I've also filled a bug report before, but I might have not done it properly. It also seems like I'm not the only one having this problem.

If you need any information or reports, please ask. I would really like this being sorted out as it has been going on since installing Ibex at the end of October 2008.

My interfaces file:

auto lo
iface lo inet loopback

Here are some outputs that I hope will help:

Thanks for the input provided, please check this bug from debian

http://groups.google.com/group/linux.debian.bugs.dist/browse_thread/thread/d3264d8910ce742e?pli=1

and try the workaround in there:

configure
 eth0 via /etc/network/interfaces and set

[ifupdown]
managed=true

thanks

[Conrad Theart (conradtheart-deactivatedaccount)]

That thread make me really appreciate proper forums! Everything is so messed up there, or is it just me?

I don't have a eth0 in my interfaces file. I tried to check the manages=false to true in /etc/NetworkManager/nm-system-settings.conf and add "auto eth0; iface eth0 inet loopback to my interfaces file, but nothing.

Am I missing something?

[Conrad Theart (conradtheart-deactivatedaccount)]

Just want to make sure this is still seen and not resolved. Thanks.

[Brian Murray (brian-murray)]

Your interfaces file should have:

auto eth0
iface eth0 inet

There should not be the word loopback there. In the event you are still having problems with this please add the full contents of the /etc/network/interfaces file as an attachment. Thanks in advance!

[Conrad Theart (conradtheart-deactivatedaccount)]

Hi Brian,

I did what you said both with and without the first 2 lines in my interfaces file and also with and without changing managed=false to true in my nm-system-settings.conf file, but still nothing. When my interfaces is like it is now (file attached) and managed set to false it says device is unmanaged when I click on my network app.

[Conrad Theart (conradtheart-deactivatedaccount)]

Any info for me? I don't quite understand why this is marked as incomplete?

[nhasian (nhasian)]

please post the output of:

ok according to the triage at the channel and:

and

I 'm marking this as dupe from bug #274069

[Conrad Theart (conradtheart-deactivatedaccount)]

Hi guys. What was the workaround you told me to do at the channel that solved my problem? I want to help someone else to do this.

Thanks.

[Andres Mujica (andres.mujica)]

@Crown, i hope is not too late
