NetworkManager 0.7

[Ted]

    *   I am writing you this email from windows because I can't connect
      to the internet using Ubuntu 8.10 and NetworkManager.
    * I am using  a Compaq nc8430 notebook with a Sierra Wireless
      USBConnect 881 3G interface which is connected to the AT&T
      wireless broadband network.
    * I was never given any password to use the wireless broadband
      connection.  Just plug and play in windows.
    * I have created a live disk of ubuntu 8.10 and booted to it. 
      Everything appears ok. 
    * When ubuntu boots, the led's on the wireless broadband interface
      show that it is ready to operate. 
    * I then drop down the NetworkManager from the system tray using the
      right mouse button and attempt to configure the connection. 
    * I click the wireless broadband tab and enter United States for the
      location.  Next screen I click the AT&T selection.  Then I click
      finish. 
    * When I click on the NetworkManager icon in system tray the
      connection appears on the list. 
    * I click on the radio button in front of that selection and the
      menu promptly closes.  The Icon has a small red triangle on the
      lower right corner.  I watch the interface led's and the active
      light flickers momentarily. 
    * Reopen the NetworkManager menu and the radio button is not selected.
    * I can't get online.


Please tell me what I'm doing wrong.  I want out of windows but ubuntu 
is useless to me unless I can get online.  My desktop uses ubuntu 8.04 
exclusively and it works great except that I still have to use dialup 
for internet connection.  I would like to use the wireless broadband for 
both installations.  Also, I'm trying to boot ubuntu 8.10 on this 
notebook from a USB drive I created from the live disk without success.  
But that's another story I'll deal with later.  Help, Please.

Ted
