Unable to connect to internet through Mobile Broadband usb EVDO after an update to 11.10

[Abhijith Madhav]

I am unable to connect to internet through my usb EVDO device after an
upgradation of my operating system(ubuntu-11.04 to ubuntu-11.10) and
hence the network manager(0.8.4 to 0.9.1.90) shipped with it.

I can connect to the internet by using 'wvdial' from the command-line.

I am attaching the logs as specified in
http://live.gnome.org/NetworkManager/Debugging. Some other required
details are as below.

1) The release of Ubuntu I am using
kempa@kempa-Notebook-PC:~$ lsb_release -rd
Description: Ubuntu 11.10
Release: 11.10

2) The version of the package I am using
kempa@kempa-Notebook-PC:~$ apt-cache policy network-manager
network-manager:
  Installed: 0.9.1.90-0ubuntu4
  Candidate: 0.9.1.90-0ubuntu4
  Version table:

The model number on my mobile-broadband modem is "EVDO AC8700 800M"

@Abhijith: Has there been any improvement in Ubuntu 12.04?
