WPA-PSK under WinXP Pro SP1 -- does it work?

[Hans Salvisberg]

Hi all,

I'm trying to upgrade from WEP to WPA-PSK, using a Level One WBR-3403TX
Wireless Router and two XP computers with Cisco Aironet 340 PCI Adapters
(with the last firmware/drivers dated Noverber 03). One of the computers has
WinXP Pro SP2, and it works like a charm.

On the other computer I had to remove SP2 again, because it would hang
during shutdown. So I installed Microsoft's 826942 WPA Rollup Patch, and I
can actually select WPA-PSK and TKIP, but on the Authentication tab of
Wireless Network Properties the checkbox

Enable IEEE 802.1x authentication for this network

is checked and grayed, so I cannot uncheck it.

This seems to be a bug in 826942: with SP2, the checkbox is grayed, too, but
it is checked for WPA only, and unchecked if you select WPA-PSK. With
SP1+826942 it remains checked in both cases!

The result is that the SP1 computer sees the AP, but it won't connect to it,
because it can't authenticate. (I did enter the WPA key, of course.)

Has anyone seen this before? Any ideas on how to make it work?

Hans

Hi again,

The result is that the SP1 computer sees the AP, but it won't connect to
it, because it can't authenticate.

I kept on searching for answers after posting my query, and I finally found
the secret clue in an earlier posting to this group

by Mike Fulstow:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EAPOL\Parameters\General\Global]
"AuthMode"=dword:00000002

The symptoms aren't exactly the same as mine, but it helped anyway.

Thanks, Mike!
