Wireless driver has disconnected in association with AP

    I can't connect wirelessly an Acer notebook with Vista Home Premium and a
    Broadcom 802.11g board to a Dlink DI-524 router. After many negative tests
    and changings of parameters I found the valuable MS news "Troubleshooting
    wireless problems with Vista" and was able to start wireless diagnostics.
    The report is:
    "Connection failed to WLAN autoconfig service because driver has
    disconnected in the association phase with access point" (I don't know if
    the text is exactly so because I'm translating)
    Moreover it says some tests have been performed, say:
    - wireless board: ok (I knew because a peer-to-peer connection with another
    PC is working)
    - WLAN autoconfig service: test failed (anyway I see this service is
    running)
    From command prompt I run "netsh wlan show all" giving "Interface -
    disconencted" and also Ipconfig says for the board "Status - disconnected".
    This matches with router's statistics saying it has received 0 packets.
    The hint for a solution is: check board settings with router's ones
    ostazioni della scheda concordino con quelle
    dell'access point (nel mio caso il router).
    Now in the config utility of my router I see only: SSID, channel number and
    security (I'm testing with no security just to avoid successive problems)
    and of course I enabled DHCP
    With respect to Broadcom board I see as many as 21 parameters ... I can't
    understand all those radio stuff, I don't find any help in Broadcom's and
    Acer's sites - I tried to change someone with no result.
    I updated Broadcom driver (bcmwl6.sys) and router fw, I removed and re-added
    the board, now I'm giving up:-(

    two things - do you have the latest firmware for the router?
    are you broadcasting the SSID?

    ok I downloaded the last fw of Dlink DI-524, namely version 2.06 of May,7
    2007
    About broadcasting - I'm somewhat puzzled about that, now I see these
    settings at router's side:
    Channel 6
    Security none (for now)
    Beacon interval 100 msec
    RTS threshold 2432
    Fragmentation 2346
    DTIM interval 3
    Wireless mode: mixed mode (alternative "G mode")
    TX rates Auto
    SSID broadcast Enable
    - and at Broadcom's side:
    Roaming decision - optimize distance (other values: predefined - optimize
    bandwidth)
    MAC address locally managed - not present
    PCLP BSS header (perhaps is it also called "Preamble type"?) - Auto (other
    value: long)
    AP compatibility mode - higher performance (other value: extended)
    IBSS 54g mode - 54g auto (other values: 54g enhanced - 802.11b only)
    IBSS 54g protection mode - auto (other value: disabled)
    IBSS WZC channel - 6
    Path - predefined (other value: USA)
    Priority and VLAN - disabled (other values: each enabled/disabled)
    Fragmentation threshold - 2346
    RTS threshold - 2347
    Roaming trend - moderate (other values: aggressive - conservative)
    Speed - best (other values: 12 values from 1 to 54
    VMM - auto (other values: enabled/disabled)
    --------- there are some other settings that I don't think are relevant
    It is possible that some settings don't match but I'm not so good at radio
    terms
    As for broadcasting, from the settings I think that the router is
    broadcasting the wireless network - Now if you think of the well known
    conflict problem with Vista (DhcpConnForceBcastFlag = 1) I have already
    tried to disable it without result

    on the router: change the channel to 1 or 11
    set it to G only mode

    are you using Windows to manage the wireless network or some
    proprietary vendor supplied utility?

    no change
    I'm using WLAN autoconfig service, since there is no proprietary vendor
    utility and the board is integrated in my Acer notebook. The Windows trace
    says: "Wlan autoconfig service is not running because the service status has
    been set to running by the user or the application " - Now actually I see
    the process is running and has been set to authomatically started - I don't
    understand at all...
    As for the broadcast question, I noticed that among the properties of my
    Wlan it appears "Radio frequency type: non broadcast"
    Now do you know about some trace utility showing at low level what is
    travelling on the wireless net? I understand this is a configuration
    problem, yet I'm not able to set the correct matching...

    do a factory reset on the router (which will wipe out all settings)
    - usually there is a reset button or hole on the back, use a paper
    clip while it is plugged in and wait for the lights to start
    flashing and then stop flashing, then unplug it and plug it in a few
    times. then go in and change the SSID to something like

    wireless123

    don't make ANY other changes.

    can you connect or not?

    IT WORKS !!!!!!!!!!!!!
    I was already giving up since it's a month I'm trying...
    now I had to invoke router's reset from a button in help text since hw reset
    seemed not to work... I can't see what parameters have changed, apparently
    only SSID default name (you won't ever guess it... "dlink"!)
    THANK YOU!!!!!!!!!

    Please go back and setup security. WPA2 if possible, otherwise WPA.

    (and I'm glad you are up and running).

    just a last suggestion - now I'm puzzled about the wireless connections to
    define, when I'm at home I'd like to connect to my encrypted Wlan and not to
    my neighbour's unprotected one (and viceversa), in the contrary when I'm out
    near some public access point I'd like to connect to it in protected mode
    but I don't know its SSID, and also I think a peer-to-peer connection would
    be useful. I'm trying to create all these connections but I don't know how
    to set the 3 parameters
    1) authomatically connect when network is in computer's field
    2) connect to a network with higher preference if available
    3) connect even if network is not broadcasting - I think this has to do with
    the broadcast parameter at router's side

    you should not have to define anything.

    go into the Network and Sharing Center, manage wireless networks,
    manage wireless networks, right click your neighbors network SSID
    and select REMOVE

    if you are at an airport or other public venue, Vista will discover
    the broadcasting SSID on it's own. when you connect, Vista should
    present a window where you would select PUBLIC.

    I would not recommend setting up an ad hoc peer to peer wireless
    connection unless you need one.
