Connection/disconnection problems with wpa_supplicant and hostapd when using WPA2 encryption
Mon Jan 23 03:39:20 PST 2012
I am currently doing some tests with wpa_supplicant and hostapd and I
am facing a quite strange connection/disconnection problem when using
When the WiFi client (using wpa_supplicant) tries to associate to the
AP (managed by hostapd) is several times disconnected from the network
before finally receiving an IP address and finally being able to
Apparently, the client is 1st correctly associated (message ?State:
ASSOCIATING -> ASSOCIATED? visible in the wpa_supplicant log) but the
client is soon after disconnected due to authentication problem with
the following error message:
WPA: drop TX EAPOL in non-IEEE 802.1X mode (type=1 len=0)
Authentication with 00:0e:8e:3b:05:6d timed out.
BSSID 00:0e:8e:3b:05:6d blacklist count incremented to 2
No keys have been configured - skip key clearing
State: ASSOCIATED -> DISCONNECTED.
After this the client restarts the association/authentication
procedure and after a few tries the authentication succeed. The SSID
of the base was well broadcasted during the above described test.
Up to now, I have never seen this problem when connecting without
I can connect without problem with Windows PC with WPA2 enabled, so I
would suspect that the AP is correctly configured.
Would anyone know the reason for this ?connection/disconnection? problem?
Would this be a known issue or is it related to incorrect
configuration of hostapd or wpa_supplicant (relevant part of the
config files are given below)?
Thanks in advance for any help.
Wpa_supplicant config file:
Hostapd config file related to WPA2:
##### WPA/IEEE 802.11i configuration
wpa=2 #for WPA2 encryption
