XP SP2 WZC flakey?

    I have noticed that the Wireless Zero Configuration software in XP SP2 seems quite
    unstable with my WMP54-G Linksys wireless card. In particular, if the wireless connection
    gets disrupted for any reason (say I reset the WRT54-G wireless router), the WZC
    software gets confused about the connection. I have the WZC set up to autoconnect
    to a WPA-SPK encrypted network. What happpens is that the display of available
    wireless networks and the icon at the bottom of the screen get decoupled from
    the connection status. For instance, I can be connected (and the popup status
    shown by moving the cursor over the WZC icon shows this is the case) but
    in the available wireless networks window I have the status shown as disconnected
    and the Connect button appears rather than the Disconnect button. Furthermore,
    the WZC icon at the bottom of the screen shows the wireless connectioon as
    disconnected (with a red X). I have to reboot to resync the connection status
    throughout the WZC software. Is anyone else seeing these sorts of problems?
    ps I must admit I am very impressed by how MacOS X handles the same situation.
    Not only does the Airport software for their Airport Extreme card flawlessly handle
    a reset of the wireless router (properly showing the reconnected status) but I
    can even switch the channel used on the router,. MacOS X will follow the
    channel change on the connected network without interruption. Neat.

    same problems

    I've had the same problems with the WMP54G PCI adapter. Problems as in frequent dropped connections. I'm not sure that it's WZC though b/c the problem seemed worse if you try using the Linksys WLAN utility. The frequent drops are so annoying and time-wasting that I may go back to running a 50 foot patch cable until we can afford to run CAT5 wiring.

    When using WZC with WPA-PSK, you should always enable SSID broadcast. Also there may be other access points or routers are in your area. The Linksys WLAn utility should be removed from your PC since it interferes with WZC. If you use a sniffer like Netstumber you can, see if there are any othe wireless networks in your area and what channel they are on and change your channel.

    Turned off WWCS and Enable network access control usingIEEE.


    I turned the next WinXP options off in my laptops (with WPC54G PCI card).

    - Use windows to configre my Wireless network settings
    - Enable network access control using IEEE 802.1X

    Since then no Wireless network drops encountered anymore. It seems that in the first place the Windows authentication (which is turned on by default) is the main reason for the wireless connections to drop.
    After I disabled the settings on one laptop the drops decreased. But still the wireless part of the router got stuck and the router needed a re-boot.
    After I turned off these settings on the second (I have only two wireless PC's in my small network and 3 wired PC's) laptop the router did not need to be re-booted anymore.
    However, the wireless connection on the secondfloor was still unreliable. Fluctuating between 8Mbps and 0. When 0 was reached the PC upstairs was not able to determine anymore if the network returned.
    A few days I changed the beacon timer into 50ms and the fragmentation and RTS treshold to 2304 (found these values in the Whirlpool forum (AU) and since then (now for 3 days) the network connection is steady on floor two on 24-34Mbps with a signal strength and quality of between 40-50%.
    And what is more important: did not here any complaints anymore frmo my daughter in three days. (used to be as much complaints as wireless connection drops!)
    For long as it takes I am a happy user......;-\

    Re: Turned off WWCS and Enable network access control usingI

    The 802.1X is disabled by default.

    But anyway, my network is stable now for a while and the signal strength of the wireless part is good. WZC, IEEE authentication and the option to have windows configure your wireless network settings are turned off/disabled.
    All is working very well. That's all I want to say.
