Sony VAIO & Vista wireless connection problems

Discussion in 'Windows Vista Networking' started by Pheasant Plucker®, Feb 13, 2008.

  1. Hi there,

    I use a 3Com 3CWRDR100A-72 router that has worked faultlessly with many
    devices in my house;

    W2K laptop
    XP Tablet PC x 2
    iPAQ 2210 & Socket CF Wi-Fi card
    iPAQ 4700
    XBOX 360
    Nevo SL
    Momento Digital picture frame x 2
    20+ visiting laptops etc. etc.

    You get the idea ;^)

    I use MAC Address filtering for security.

    However I have a brand new Sony VGN-FZ21Z that will not connect wirelessly
    to it...well sometimes it has but most of the time it doesn't,

    I have the router set to broadcast SSID and the FZ21Z sees it OK.

    With no encryption the FZ21Z will not automatically connect after coming out
    of standby or being shut down.

    Using WPA it has managed to connect probably 2 times out of 20 but mostly it
    fails - the log reporting a timeout error.

    I have a Sony VAIO VGN-N38Z sat next to it that is fine even when the SSID
    is not broadcasting.

    This is driving me help my sanity and my hair can some kind soul
    offer some help/advice/tips please?

  3. Thanks for the reply Robert,

    When I removed WPA the Vista laptop started to behave itself and has been
    connected ever never done this first time round...

    As soon as I turn WPA on I get the issues.

    Will unbinding IPV6 have any bearing on this do you think?

    I will give it a go when I get some spare time and report back.

    Timeout exchanging secondary keys by any chance? My new Toshiba has a
    very similar problem when running Vista with WPA-PSK at home. About 1%
    of the time it connects the rest it sees perfect signal does the
    initial key exchange and then bombs out with a timeout waiting for
    server (exactly the same model as yours). The portable has Intel
    3945ABG WiFi chipset with driver at present (others have
    tried different drivers to no avail).

    It seems to be much worse if it has suspended due to inactivity since
    power up. I have tried disabling the power down WiFi to save power
    option but that didn't seem to make any difference.
    I am inclined to blame MS Vista and 3Com about equally for this one
    since at present I cannot find anything obviously useful on either of
    their respective knowledgebase sites. Although I intend to try out one
    WPA related hotfix (see below). And I can find lots of people
    complaining of this or very similar timeout problems when using WPA
    with Vista on various platforms and in combination with various

    It seems crazy to have to deliberately downgrade security to WEP just
    so that new hardware using Vista can connect to an existing WPA
    network. I think the problem I have may be described obliquely in the
    following MSKB:

    I have yet to obtain this hotfix and apply it. The other one that
    seems to cause trouble a bit later on after you get the encryption
    sorted out is a DHCP in Vista SNAFU. Details on that one at:

    I expect that there are some others cunningly hidden on the MSKB site
    in such a way that using the obvious keywords for the problem will not
    find the right solution :(

  5. Hi
    The statement connected means that the Wireless card sees the source signal.
    If it does not work, in most cases it a result of Not obtaining a valid IP
    from the Wireless source (an IP of is not a valid working
    Make sure that all the Wireless card parameters match the Wireless source.
    My Wireless does not work -
