wpa_supplicant fails to preauthenticate

[Ambedkar R]

 Hi,

Since you have configured with different security and SSID policy for two different AP's,you can't perform Pre-Authentication.

To perform Pre-Authentication following things are required,they are
1.AP should have the support for WPA2-Enterprise/CCMP
2.Client should support for Pre-Authentication.

Configure AP1 and AP2 with same SSID and Security Policy(WPA2-Enterprise desired)


Thanks
