Title:
  Huawei broadband modem fails to connect in 12.04 Alpha (Precise)

Status in “network-manager” package in Ubuntu:
  New

Bug description:
  System information
  ===============
  Distribution: 12.04 Alpha
  Kernel: 3.2.0-2-generic #5-Ubuntu SMP
  Status: Vanilla installation
  Package: 0.9.1.90 (via NetworManager --version)

  Problem Description
  ================
  The Huawei USB Broadband dongle which works perfectly in 10.10 fails to work in 12.04 Alpha.
  Although the problem was reported under bug #840082 and resolved via a 0.9.0-ubuntu3, it creeps back into 12.04 Alpha.
  The system is able to detect the dongle, it reports logging into home network
  However, trying to establish internet connection will result in failed connection.

  Work around
  ==========
  * this was accidentally found while trying to study the problem.
  1. Find the pid of NetworkManager (ps -aef | grep -i networkmanager)
  2. kill -9 <PID>; NetworkManager --no-daemon
  3. try to connect to internet, for my case it works. No guarantee though.

  Next Step
  ========
  will be doing a complete upgrade of all packages (apt-get upgrade -y) and test it again.
