wow.
thanks pal. you just saved me.
I just edited the file /etc/NetworkManager/nm-system-settings.confand turned managed (ifupdown) into 'true' and it got working again.
thanks again.

No problem - I have received SO much help from these forums, it's nice to give a little something back if/when I can.

Also, you should change the title of this post to include [SOLVED] now that you have found your solution.

Cheers!

i checked out the link for the bug u gave, but my /etc/network/interfaces looks very different from what is given there, except for the first two lines; so hw do i fix it?

**YWELLC** · February 28th, 2009

Post the output of:

Code:

cat /etc/network/interfaces

and

Code:

cat /etc/NetworkManager/nm-system-settings.conf

Sorry about the comment to changing the post to solved in my last post, I didn't realize it wasn't the OP who got it fixed.

Try this:

Code:

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

Change

Managed=false

to

Manged=true

Then open up the NM applet via System>Preferences>Network Configuration

and if there is anything listed there other than "ipupdown", (for me this is Wired Connection 1) click edit, and check off "Connect Automatically" and "System Setting" then reboot the system.

Hopefully that will resolve this minor annoyance.

I am afraid this didnt work for me. My network connection stopped working when i changed Managed=false to Managed=true; and there are absolutely no connections listed in the NM applet, not even the ipupdown u mentioned.
