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
uninstalled?

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
helpful.

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.

Tani:
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
w/AES?

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.
