After installing 11.04 alpha2, I cannot access to internet.
I use wireless lan. In network connection dialog, it seems to work well.
But I cannot access any webpages from webbrowser. Even if I use direct ip address -So it is not dns problem.
I cannot download newer version from update-manager. It doesn't work either.

What should I check?
Can I rollback the update? I'm so frustrated and regret.

  • Might sneak in under can I rollback the update. Probably not. As to the networking stuff not working, I would lean towards a driver issue as natty networkmanager et al works for me. – RobotHumans Feb 5 '11 at 7:09

Unlike Windows Ubuntu doesn't create system restore points to 'rollback' to.

You would have to reinstall 10.10 from scratch but you can back up your data in your /home directory and start over.

Natty is only an Alpha release and not recommended for a production install - you'd be better off to install it onto a USB stick and run a live version to test and report bugs.

  • Thank you. I just reinstalled 10.10. I'm not gonna taste alpha version again! T.T – Benjamin Feb 5 '11 at 8:55
  • I recommend you install to usb as detailed on Jono Bacon's blog jonobacon.org/2010/11/30/… – Mark Rooney Feb 5 '11 at 9:52
