When I boot from Ubuntu 9.04 liveCD, I can use my wireless internet. I have no idea how this tool is called, but it is in the upper right corner, lets me choose among detected wireless networks, enter key, etc.

When I use apt-get in terminal (being in LiveCD) it's all OK, internet connection works and aptitude downloads everything it needs.

Is there a way to keep using this connection even after chrooting into somewhere else?

I need to chroot to my "real" Ubuntu install in order to fix it (got messed up). So I do chroot /media/disk and from there on I have no internet connection in terminal. So if I use apt-get install ubuntu-desktop, apt-get complains about not being able to resolve ubuntu http repository urls or something like that. Exactly as if I boot into real, messed up Ubuntu install I want to fix, because it has no working internet either.

Just added a detailed chroot tutorial here. One thing you should do is copy your /etc/resolv.conf file over before doing the chroot. That may be all you need to fix this.

(I was confused by the comment until I noticed quack started the community wiki question I linked to.) –  dubiousjim Feb 20 '10 at 17:11
    
(and i found it odd that there was suddenly another chroot question until i realized... it was posted by the author of one of the questions that prompted ... my CW chroot question! ha!) –  quack quixote Feb 20 '10 at 17:17

Copying /etc/resolv.conf did the trick! –  Sejanus Feb 23 '10 at 11:12
