Failed to set encryption with wpa_supplicant v0.2.1

Hello all

I got some error messages during running wpa_supplicant.


Ioctl[PRISM2_IOCTL_HOSTAPD]: Invalid argument

Failed to set encryption.

Unknown algorithm 'TKIP'.

You may need to load kernel module to register that algorithm.

E.g., 'modprobe hostap_crypt_wep' for WEP.

Failed to set PTK to the driver.


Does anyone know how to solve this issue?
