Is the network manager in Oneiric different from Natty? How can I get the old one back ? Or is it the problem with some packages ? I used to connect to internet using my mobile broadband device using one click. Now I've to remove, replug, restart atleast 10 times to connect it.
Since you've asked, I'm using Natty and Oneiric with the same /home partition with the same username. So, it's a fresh install of Oneiric not an upgrade. The same problem appeared with the live cd and while installing Oneiric.
Also, even after I enable mobile broadband ( below enable networking, wireless) , when I click on the mobile connection and it tries to connect, it displays as 'not enabled'.
