Seems to have a bug, I have same problem. Fresh install edited Network Manager then tryed to connect to the new dsl and did Not connect, then restarted and ifupdown (eth0) replaced auto (eth0) and removed my dsl connection. Then went to use pppoeconf under console.
I thought it was the beta RC i was using.,yet am currently on the Final 9.10. ugly and needs to be patched!

I have the same problem. I use Static IP Broadband connection. this is a bug I think. It should be reported to the UBUNTU Bug report center( I don't know how to do it.)

[SawyerLX]

yeah, connecting via
"sudo pppoeconf"

Funny I told somewone this is probably the best OS i have seen.
Until this problem made me realize I had to text someone the next day to give the above command,
Otherwise,
it is extremely smooth and no other problems.

This is essential bug fix:

Network applet configures wired ethernet name to grab the ethernet card caller right.
and thatlss be the fix...I;m an idiot, but you get the jist.

maybe version 9.10.?

NetworkManager is the best way for end-users to configure their network I think these problems are happening with people who configured their networks using the command line using some cut-and-paste fiddling with pppoeconf or stuff in /etc.

To have NetworkManager manage all interfaces without editing ifupdown/interfaces files, this should work.

Check /etc/network/interfaces.

Press alt+F2 and paste in:

gksudo gedit /etc/network/interfaces

Remove everything but

auto lo
iface lo inet loopback

Then Check /etc/NetworkManager/nm-system-settings.conf
Press alt+F2 and paste in:

gksudo gedit /etc/NetworkManager/nm-system-settings.conf

set

 [ifupdown]
managed=false

Restart computer or NetworkManager service.
From now on, only configure the network using the NetworkManager applet in the notification area (aka system tray).

If this doesn't work, post here again.

this is working excellent . the problem has been solved. Actually I do the change etc/network/interface file manually due to my internt connection problem.

ALAS!!! Problem solved. The reason I messed around with CLI is that at home I used DSL (pppoe) and at work I'm on ethernet. I gets a bit tricky for me to define both. I try defining DSL thru NM 2nite.

Edit: Sorry, I forgot to say thanks. I'm in such a hurry to navigate Karmic...

You know I already have it at managed=false, but
I did fresh install, used "pppoeconf" then two updates before I tried to work on NM by changing the file to see if nm-applet would get rid of ifupdown(eth0) problem.

i changed managed=true to see what happens.
while waiting for continually/any updates, If NOTHING for Network Manager is fixed I am going to change conf file back and wait for updates.
