Please enable some debugging by changing logger_stdout_level to 0 and
debug to 2. Then start hostapd into foreground, direct debug output
to a file, and send results of the client trying to associate with the

What firmware version are you using? You can get this with either
'hostapd_diag wlan0' or 'ethtool -i wlan0'; or just look at kernel log
