    I am running Windows XP Professional SP2 and using a Linksys WRV54G wireless
    router.

    I configured my laptop to this router and selected the Disabled feature for
    SSID broadcast but can still see my network in the View Available Networks
    window. I reset my router, shut down all my devices and brought the network
    up again. Same thing. Am I seeing my network because I configured the router
    using my laptop. Linksys says I shouldn't see it.

    If anyone knows exactly what I should or should not be seeing in the list of
    available networks, I could use the help.

    Here's a copy of my exchange with Linksys Support:

    I tried what you suggested, but my network SSID could still be seen in the
    list. Next, I reset my WRV54G and re-configured it. I powered down my
    devices and restarted everything, but my SSID still appears in View
    Available Wireless Connections. I can't seem to disable SSID Broadcast. Do
    you have any idea why this is happening?

    Thanks so much!

    Dear Valued Linksys Customer,



    Thank you for contacting Linksys Customer Support.

    Good day. After applying the settings on the router, it would help if you
    would power cycle the devices so that it would refresh it to apply the
    settings on the router. Once the SSID broadcast has been disabled, it should
    not show up when you browse for the available wireless networks.



    Sincerely,

    I configured my router to disable SSID broadcast. However, when I go to
    Start> Connect To> Show All Connections, and then right-click on the
    Wireless Network Connection icon, and then select View Available Wireless
    Connections, I can still see my network listed in the Choose A Wireless
    Network list.

    Should my network still be visible in the list on my main computer? Is there
    any way to test that my network is indeed invisible to other computers?

    I am running Windows XP Professional SP2

    Yes, you are probably seeing the SSID because you configured and connected
    from this machine. Frankly, most of us who are networking professionals
    consider disabling the SSID to be bad advice and pointless. You should use
    encryption (preferably WPA) to secure your network. Disabling the SSID
    provides no significant security benefit and often causes connection
    problems and interruptions.

  3. Hello mszablocky,

    Are you using WPA2 by any chance? If so, the WPA2 update can make hidden
    SSIDs (network names) available in the Choose a Wireless Network dialog box.
    For more details, see the following link.

    The Wi-Fi Protected Access 2 (WPA2)/Wireless Provisioning Services
    Information Element (WPS IE) update for Windows XP with Service Pack 2 is
    available

    Thanks for taking the time to help me out, all. I tend to agree with GTS's
    call, however. Since my laptop is my only computer (networked to a couple of
    peripherals) I think it probably has to show up. I didn't realize that
    disabling SSID broadcast made so little difference in security.

    And no, Eric, WPA/WPA2 is not involved at all. I use 128 bit WEP because my
    print server does not support WPA.

    Thanks for a nice first experience on this newsgroup!
