I would suggest starting with only one pairwise cipher configured. There
have been some problems with enabling both of them in some
configurations. It'll be easier to test this once the simplest case has
been known to work.

What clients are you using (operating system, wlan hardware, driver,
supplicant, version numbers)?

This is normally a sign of either incorrectly configured WPA
PSK/passphrase or an implementation error. Are you sure that the same
passphrase is configured in both the AP and client?


PS.

hostapd v0.5.1 has a bug that would break the next msg 3/4, so even if
you get through this msg 2/4, you should really upgrade to 0.5.2 in
order to be able to complete authentication successfully.
