Does WPA and WPA2 wireless encryption work on Vista?

    I have Vista Home Premium with SP1 and all the updates installed. I
    have a MSI PC60G wireless adapter, with the latest driver, and it is
    unable to connect to my Linksys WRT54GL router with WPA or WPA2. I
    know that the router is working fine, because I can use an XP laptop
    to connect to the router using WPA or WPA2. But with the Vista
    machine, it always shows a "The wireless network security key is not
    correct" when I use the diagnose option to see why it doesn't connect
    using WPA/AES or WPA/TKIP or WPA2/AES or WPA2/TKIP. Vista can tell
    that the network is there, as it shows the network name with 5 green
    bars in the wireless connection window. It can also tell when I have
    changed the security settings on the router, as it will say "The
    settings saved on this computer for the network do not match the
    requirements of the network." But it just won't connect to the router
    using WPA or WPA2 for some reason. If I configure the router with
    WEP, then Vista connects fine, but I want to use WPA or WPA2.

    Can someone please confirm that wireless connections using WPA and
    WPA2 are working in Vista? If so, then it must be a problem with the
    PC60G wireless adapter. The PC60G uses a Ralink RT2561 chip, and I
    have the latest driver installed for that. I even tried the latest
    MSI driver, which is older than the latest Ralink driver, and that
    still did not work. MSI says that the PC60G supports both Vista and
    WPA2, but something is not working here.

    They both work with Vista.
    1. Update your router's firmware at the Manufacturer's website, so it is
    fully vista compatible
    2. Get the latest Drivers for your Network Adaptor.

    We use WPA-PSK/TKIP with XP, Vista and Linux.

    The router works with XP and WPA/WPA2 (I tested that), so it should
    work with Vista, since the router wouldn't know what OS the clients
    are running. I also saw someone saying they are using Vista with WPA2
    and a WRT54GL. But I can try upgrading to the latest firmware later.
    Yes, I tried that and they still don't work.

    Some routers can not handle the newer Vista features - upgrade the
    firmware on the router

    What firewall software, if any, are you using on this Vista PC? I've
    encountered a firewall software that blocks wireless SSIDs if not told
    to trust it.

    The Windows Firewall. But WEP works on the computer. WPA and WPA2 do
    not work.

    Well, I tried it one more time tonight, and it worked. Bizarre. Hmm,
    yesterday I had been uninstalling and re-installing different versions
    of the wireless adapter drivers, and something must have gotten
    corrupted, because after all that, WEP wouldn't work anymore. So I
    did a System Restore. That must have also fixed WPA2, because it is
    working now.

    Vista is a @$%#%$# of a system if you want to get WPA security working on your wireless system

    It took me many hours of stuffing around, nothing on the micrcosoft site (that I found) tells you what you need to do.

    To get it to work you must set it up manually, with the following settings.

    You must manually set the:
    Security Type to WPA-Personal
    Encryption Type to TKIP

    Unless Vista is set to these setting it will not work, and gives just you vague messages to essentially say it cannot fix it.

    TP-Link WA601G router was set to WPA-PSK/WPA2-PSK
    with automatic Version selection and automatic Encryption selection

    sounds more like your router or wireless adapter/driver is the
    problem here. for most people, this works transparently.

  14. Hi
    The operating system (Vista or other) get the cues about Wireless from the
    Hardware Drivers (al most all of them are provided by the original
    Some of the Automatic thingies in some Routers Routers, or and, Wireless
    Cards utilities are Not Standard.
    So if the Router and the card are Not matching pair of the same
    manufacturer it might not work Auto., and needs manual configuration.
    In your case it seems that your hardware can do WPA and Not WPA2.
