Hello all,
Sorry if I'm writing to wron mailing list. From my uneducated point of view it
looks like problem in driver
but I may be wrong.
I'm having following problem. Wireless card of my laptop associates and
authenticates successfully with
access point. After some time of successful usage (5-10 minutes) AP sends
deauthentication with reason
code 2, which AFAIU is "Previous authentication no longer valid". Sometimes
reson code is different (I saw
3 and 23) but mostly it's 2. Then card reassociate and reauthenticates
succesfully and gets deauthentication
immediately. And then it runs like that in loop forever. Card is controlled by
wpa_supplicant and if I kill it (ifconfig
shows that interface is down after that) and then restart wpa_supplicant card
connects to AP successfully. Below
are technical details.
WPA configuration:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1
network={
scan_ssid=0
ssid=".........."
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP WEP104 WEP40
psk="............"
}
network={
ssid="any"
key_mgmt=NONE
priority=2
}
