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?

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!

Barb:
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?
