Questions with wep keys for WinXP

Hi, Jouni, Thank you very much for the help.
Now, if I turn both of broadcast_key, and individual key on, and have the
workaround set to 1, my Exp
setup works prefect.
I tried another way also. If I turn the individual key on, and default wep
key off. WinXP only receives
the unicast key after authentication succeeds. This is what I expected. But
WinXP client CAN NOT get
an ip address through DHCP. Since a DHCP request is a broadcast, I doubt if
something is wrong with the broadcast key.
So, if WinXP doesn't receive a broadcast key, will it use the only unicast
key to encrypt a DHCP request?
How will the hostAP handle this ?
Thanks for any point.

Please re-read the comment about the workaround.. It is needed _only_ if
you are not using individual keys. Enabling both broadcast and unicast
keys is enough to make WinXP Supplicant happy with the EAPOL-Key

There is a flag in key_index field of the EAPOL-Key telling whether the
key is broadcast (default key) or unicast (key mapping key).
