What wlan cards and drivers (including version) are you using in the AP
and client? Can you please send debug log from wpa_supplicant for the
failed case?

Group key handshake is the first user of the just configured pairwise
keys and failure here could indicate that either the client or the AP
has not configured TKIP keys properly at this point. Are you saying that
the data connection works fine with RSN?
