    Question Network manager is broken (?)

    Hi all,

    after seeing this behaviour http://ubuntuforums.org/showthread.php?t=1041683
    I've figured out what's wrong.

    When I first login to Ubuntu with my profile the Network Manager applet says it's trying to connect to my own wireless (I can see it let left-clicking on the icon, the dot is on my own wireless).
    But when I run iwconfig from the terminal I see that the network it's trying to connect is another:

    eg:
    Code:
    lo        no wireless extensions.
    
    eth0      no wireless extensions.
    
    wmaster0  no wireless extensions.
    
    wlan0     IEEE 802.11abgn  ESSID:"<another network not encrypted>"  
              Mode:Managed  Frequency:2.462 GHz  Access Point: Not-Associated   
              Bit Rate:54 Mb/s   Tx-Power=15 dBm   
              Retry min limit:7   RTS thr:off   Fragment thr=2352 B   
              Power Management:off
              Link Quality=70/100  Signal level:-64 dBm  Noise level=-92 dBm
              Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
              Tx excessive retries:0  Invalid misc:0   Missed beacon:0
    
    pan0      no wireless extensions.
    And it doesn't connect.
    Then when I force it to connect to my own wireless:
    Code:
    sudo iwconfig wlan0 essid "<my WPA+WPA2 wireless>"
    I'm able to successfully connect and if I execute iwconfig
    Code:
    lo        no wireless extensions.
    
    eth0      no wireless extensions.
    
    wmaster0  no wireless extensions.
    
    wlan0     IEEE 802.11abgn  ESSID:"<my WPA+WPA2 wireless>"  
              Mode:Managed  Frequency:2.442 GHz  Access Point: 00:1D:68:08:D2:4D   
              Bit Rate=54 Mb/s   Tx-Power=15 dBm   
              Retry min limit:7   RTS thr:off   Fragment thr=2352 B   
              Power Management:off
              Link Quality=100/100  Signal level:-40 dBm  Noise level=-93 dBm
              Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
              Tx excessive retries:0  Invalid misc:0   Missed beacon:0
    
    pan0      no wireless extensions.
    It connects.

    Am I the only one experiencing this behaviour?
    What is the config file to edit to make Network Manager work?

    Thanks in advance,
    Cheers,
