    Need some help here. OS = Vista.

    Repeatedly I'm unable to connect to wireless networks at various locations (coffee shops, bookstores, etc.) offering free, unsecured wireless networks.

    Others I'm with are able to connect without a problem, and I have no problems connecting wireless at home. This only occurs when trying to connect to a network other than my home wireless.

    Any ideas?

    are you able to see their ssid being broadcast? do the networks show up when you "view available wireless connections"? tried disabling/reenabling your adapter?

    Yes, the networks are there. It'll even say "Connected," but the browser disagrees.

    Not sure about the ssid. Where would that be?

    And how do I adjust the adapter?

    Sorry, I'm a techno-neophyte.

    Thanks for the help.

    so it says connected, you just cant get anywhere.
    is the icon in the clock bar with the wireless beams?

    Which other networks can you connect to besides your home?
    What are the main differences with the ones you cant connect to?

    While you are on your home PC, go to your command prompt and type:
    ping www.yahoo.com [enter]
    ipconfig /all [enter]

    and paste it here

    Next time you are "connected" at Taco Johns, do the same thing, paste it to a text file and paste it here.

    Changes that may help to increase the compatibility of Vista with older networking devices:



    Disable the IP Helper service:

    1. Hold the Windows key and type R, enter "services.msc" (without the quotes) and press Enter
    2. Scroll down to the IP Helper service, right click on it and select Properties
    3. In the dropdown box that says "Automatic" or "Manual", set it to Disabled and then click on "Apply"
    4. Then click on "Stop" to stop the service from running in the current session
    5. Click OK to exit the dialog



    Disable IPv6:

    1. Hold the Windows key and type R, enter "ncpa.cpl" (without the quotes) and press Enter
    2. Right click on each network connection and select "Properties"
    3. Remove the checkmark from the box next to "Internet Protocol Version 6 (TCP/IPv6)
    4. Click OK to exit the dialog

    NOTE: You should do this for each network connection.



    Disable the DHCP Broadcast Flag:

    Link: http://support.microsoft.com/default.aspx/kb/928233
    1. Hold the Windows key and type R, enter regedit and press Enter.
    2. Locate and then click the following registry subkey:
    3. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
    4. In this registry path, click the (GUID) subkey to be updated.
    5. If the key DhcpConnForceBroadcastFlag does not exist, use the Edit menu, point to New, and then click DWORD (32-bit) Value. In the New Value #1 box, type DhcpConnForceBroadcastFlag, and then press ENTER. If the key exists, skip this step.
    6. Right-click DhcpConnForceBroadcastFlag, and then click Modify.
    7. In the Value data box, type 0, and then click OK.
    8. Close Registry Editor.
    NOTE: You should do this for each and every GUID subkey.
    NOTE2: (GUID) is a mnemonic for the individual subkeys, the actual text "GUID" does not appaer.




    The only program I'm aware of that currently relies on IPv6 is the new Windows Meeting Space. The first 2 changes will cause that program not to work - but will leave all of your normal (IPv4) connections unaffected. If it causes problems that you can't overcome, simply revert back to the original settings.

    Completed each of these steps, but it didn’t fix the problem.

    In the Networks and Sharing Center it shows that I’m connected to the network, but there’s a big ugly X between the network and the Internet.

    I’ve run all the available diagnostics. The only response that seems to get at the heart of the problem:

    "A problem with your network router or broadband modem might be preventing an Internet connection."

    Any ideas?

    Actually, the "away from home" configuration shows you are not getting an IP address from the wireless network. This is usually an encryption or MAC filtering issue.

    Have you removed all the stored network profiles and searched for new networks?
