wpa_supplicant returns "no WPA/RSN IE" error, Fritz!WLAN usb
Hi.
after getting my Fritz!WLAN USB stick recognized by my system, i am having difficulties getting the connection to work properly.
The access point (which is not mine and hence i have no control over) uses WPA2 encryption with a preshared key. hence wpa_supplicant is configured for RSN.
i run wpa_supplicant as root. the result is an endlessly looping attempt to connect to the AP. It detects the access point, but then states that "skip - no WPA/RSN IE" and "no suitable access point detected". I have tried using wireless extensions, ndis (windows driver) and native driver. The native driver I use is provided by the manufacturer, AVM, so I guess it actually should support WPA2. The network functions without further problems under windows, so i guess i have a configuration error somewhere.
The config is:
Code:
#
# wpa_supplicant configuration file
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=root
# IEEE 802.1x eapol. wpa_supplicant was compiled for 2, some AP
# however seem to simply drop eapol2 frames for some reason...
# set to 2 if AP supports it
eapol_version=2
ap_scan=1
fast_reauth=1
network={
disabled=0 # network can be used
ssid="Hive"
scan_ssid=1 # do scan ssid (when ssid broadcast is not
# support or multiple ssid's exist)
priority=1 # desired network
mode=0 # managed
proto=RSN # WPA2 IEEE 802.1i
# key_mgmt=WPA-PSK #only needed for WPA IEEE 802.1i/D3.0
auth_alg=SHARED # WPA2 requires shared algorithm
psk="asecretpassphrase"
}
network={
scan_ssid=1
priority=0
psk="asecretpassphrase"
}
In detail, the wext reads as follows when running wpa_supplicant:

This appears to be a common problem, i.e. I have found many threads reporting this or similar errors (some with WPA, other with WPA2). However none ever reaches a conclusion...
Did anyone have the same problem before? How did you solve it?
Thanks |
