    Am currently using WEP but would like to switch to WPA-PSK ... have read
    several articles which recommend AES over TKIP. In these articles WPA w/ AES
    is referred to as WPA2 which is a bit confusing to me ... is WPA1 just the
    TKIP standard?

    I checked the specs of my router and wireless adapter, both list support for
    WPA and AES support but doesn't specifically mention WPA2. Will I only
    benefit from installing the KB893357 patch if I have WPA2 hardware? Will it
    cause problems if the patch is applied to non-WPA2 hardware? Can the patch be

    You can find the answer to George Ou's blog "http://blogs.zdnet.com/Ou/?p=67"
    where he explains WPA and WPA2. I am sure you will find that article very

    Thanks for the blog link, it helped clarify the "standards" issue. I still
    need clarification on the MS patch (should I install it, can it cause
    problems and can it be uninstalled if needed?)

    You may remove KB893357 hotfix if it causes any problem (to be 100% sure
    create a restore point by yourselef before applying it, although windows does
    it automatically).
    You have to install it if you hardware support "simple" WPA. WPA2 mandates
    AES mode of encryption. You may find further information about Microsoft WPA2
    in another post of George in http://blogs.zdnet.com/Ou/?p=61.

    I'm confused by something you said in your last response, "You have to
    install it if you hardware support "simple" WPA. WPA2 mandates AES mode of
    encryption." It seems like you're saying that everyone who has WPA hardware
    "should" install this patch? What about someone whose hardware supports WPA

    PS: Appreciate all your assistance ... thanks!!

    I've seen no problems with a large variety of original generation
    802.11g cards and 802.11a cards -

    You really should move to at least WPA even if your hardware does not
    support WPA2 because WEP is truly so easy to break.

    Could you post a reply here with the exact brand and model hardware
    you are using - you might get advice from someone who has the
    identical equipment and is using it with the WPA2 update.

    Yes, the WPA2 patch *should* work with WPA1 hardware.
    However, as with any other patch, there is a risk.
    There always can be a marginal bug lurking in the driver of your WPA "1" netcard, if it is not
    specially tested with this patch.
    So, undertake the usual measures (backup... backup... ) before trying it.

    Good luck,

    My hardware is:
    Belkin F5D7230-4 router ... manual says supports WPA w/ TKIP or AES
    Belkin F5D7010 wireless NIC ... manual says supports WPA w/ TKIP or AES

    That's some good advice "(backup... backup... ) before trying it" when
    undertaking any OS patch ... thanks.

    Your router uses the Broadcom chipset just like Linksys, Microsoft and
    Buffalo. It will do TKIP fine, AES might be slow. The NIC depending on
    what hardware rev and firmware is either Broadcom or Ralink (for the
    3000 series I think). The card should do AES with either, but the
    processing power of your router is the key factor. In any case,
    installing the WPA2 patch should not impact your connectivity. I'd
    recommend installing the patch and useing TKIP for starters now (even
    if you don't apply the patch).

    It works here on a huge variety of WPA1 NICs from multiple vendors.

    Thank you for the recommendations, especially the detailed suggestions on
    which encryption mode to use and for including your reasoning. I'll switch to
    WPA immediately and then apply the patch.

    The WPA patch install and switch to WPA went fine ... I had no glitches and
    everything seems to be OK, except for 2 things:
    1) the update (KB893357) is not listed in Add/Remove Programs list ... I was
    led to believe it could be uninstalled so I assumed it would be listed here.
    2) Automatic Updates which appears to have stopped working ...

    Auto Updates had been working fine for months. The only recent change I've
    made to the system was yesterday when I installed the WPA patch, rebooted and
    about a half-hour later was notified (as I had it configured to do) that
    updates were available. Looked over the list of recommended updates and OK'd
    download ... Yellow shield in Notification Area said "downloading 0%" and
    went away.

    I can't see how this could be related to installing the WPA patch but that's
    the only change I've made. Perhaps Auto Updates just "failed" during that
    attempt but since then it has not retried the downloads even after I
    reconfigured it to "full" auto operation ... received no error msgs when
    changing settings, etc. Also, checked "services" list and it's automatically
    starting. Everything seems in order but it ignores the "time" it's set to
    perform the updates.

    Any ideas on these two issues?

    In add/remove programs, you need to check show updates. Does this
    expose the KB hotfixes.

    Can you open Internet Explorer, Tools menu, Windows Update and do a
    Custom update and download anything that was missed?

    Aha! Missed that little check-box at the top ... WPA patch is listed.

    Yes, I can go to Windows Update site but didn't download anything so I could
    continue monitoring the problem. And as usual in the
    weird-wonderful-world-of-Windows, while reading this and other posts Auto
    Updates sprang back to life and performed the downloads! Still not convinced
    that all is well since it's configured to check at 9am and despite my system
    being on all day it performed the check at 10:30pm !! I guess it's just a
    wait and see now ... any other suggestions?
    Guest, Jun 16, 2005
  18. I have two systems that seem to get delayed checks. But they do get
    the auto downloads. Could be the MS servers are busy or the local
    computer is busy...

    Thanks for the input ... I had Auto Updates configured to "notify only" but
    for the time being I'll leave it on "full auto" and just keep an eye on it.
    Thanks again, I really appreciate all the assistance you've given me!

    One more question about WPA.... If I configure my router for WPA-PSK w/ AES
    then my friend whose laptop supports TKIP (but not AES) won't be able to
    connect to my router, correct?
