    I have just bought a new laptop running vista home basic. I came home and it connected straight to my home network, no problems. When I go to work, I can connect to the network, but cannot connect to the internet. Our computer tech spent 4 hours trying to connect me, and then told me I had a faulty wireless adapter (clearly not the case becuase I can connect to my network, and my neighbour's). I tired using a usb wireless adapter but same problem exisits. I have the correct wep kep typed in, and my mac address for both the internal and usb adapter have been enabled. The novelty has now worn off not being able to do anywork at my job. Is there anything that can be suggested?

    Are you using hex WEP keys or the passphrase option at work? Some different brands of hardware and drivers translate the passphrases differently.

    I'd also note that WEP is not very secure, maybe your work should consider upgrading to real encryption. :)

    I use a hex wep key at work. I don't have any say in the encryption they use, but I would say I have little faith in the computer tech. So maybe a new tech and a new encryption could help.

    Assuming you now have a profile of your work network stored, delete it. Make sure you have the correct hex key and try again.

    Done that 25 times. It's all set up perfectly. I should mention that I was able to browse the internet for one day, but it stopped after that and now there is only local connection to the network and no internet.

    If "it's all set up perfectly" I don't see how we can help make it any better.

    OTOH, since you appear to still be having a problem please show for an attempted connection ...

    Start, Run, CMD, OK to open a command prompt:
    (For Vista type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    Do you only have one technician where you work? Wireless connectivity might require more than a simple WEP key such as certificate or PEAP authentication.

    The details above are taken whilst connected to a different wireless network (same computer). I have no trouble connecting anywhere else, but work.
    Yes, we only have one tech. I had a laptop connected to the network until last week, when the hard drive failed, so I bought a new laptop and used the exact same settings, but now can only connect locally. I have treid a usb adapter which I was assured would solve the problem.

    You're not going to resolve this without talking to someone who administers the network where you work. I can guarantee that there's more to the process of authenticating wirelessly than simply entering a WEP key. You already know there's nothing wrong with the laptop or the wireless adapter. That only leaves one other option, and you're not going to be able to troubleshoot anything on the work-side of the network without the proper rights, physical access, and overall training.

    Perhaps the tech is new or hasn't been trained on the wireless network infrastructure. There must be someone he reports to or maybe another IT consultant you can bring in to resolve the issue.

    No. The tech set up the network. It is a simple network with only 4 computers and one printer connected to it. I have access to all the equipment, and have connected 2 other computers with no trouble. I have connected this computer to other networks with no trouble. There seems to be some issue between this particular computer and the network. This is the only system using Vista and I hoped someone could give me some useful advice about known issues or that someone may have had a similar problem which they managed to solve.

    Then turn off encryption and see if it works.
    Post the make and model info for all the networking equipment.
    Where are you sitting in relation to the location of the wireless access point / wireless router?

    I'm at home at the moment (hence my internet connection), but will post all hardware info when I return to work. I sit about 2 metres away from all the equipment. Apparently there are no problems when I'm connected by cable (according to tech fella, but I haven't checked this for myself).

    Thanks for the microsoft link. I had already found that, but didn't know which subkey corresponds to the network adapter that is connected to the network. Can you help me out with that?

    "2.Locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
    In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network." I have four different subkeys listed there.

    Change the settings on all of them.

    Here's my "cookbook" for fixing Vista with some network equipment.

    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.
