This is very odd.. 2) is completely invalid configuration because
shared key auth requires a pre-configured WEP key and WinXP will deauth
if "the key is provided to me automatically" is selected, but IEEE
802.1X is not used.

Which client card and driver version are you using on this laptop?

WinXP/driver is doing something wrong if 2) works with static WEP key
configuration in the AP.. Is the client disconnecting after about five
seconds or is the connection working fine after this? It looks like the
driver does not configure the client card properly for shared key
authentication when using static WEP configuration.
