As I see this commit is connected with WEP keys only, but yes - it's =20
already included in my driver version.

Sadly not. Same thing with sw and hw crypto.

AP wireless security tab

	Security Mode:	 	WPA Pre-shared key=09
  	WPA Algorithms: 	TKIP (only tkip available)
  	WPA Shared Key:	 	*******
  	Group Key Renewal:      3600 seconds

So there is no option to disable group rekeying.. I can only change it'=
s =20
time - 3600 s is default, and maximum value, 600 is minimum.

wpa_supplicant.conf:

ctrl_interface=3D/var/run/wpa_supplicant
ctrl_interface_group=3Dadm

ap_scan=3D1
#fast_reauth=3D1
#eapol_version=3D1



network=3D{

	priority=3D60
	psk=3D0000000_made_wtih_wpa_passphrase_and_my_SSID_0000000000
}

With uncommented proto, group and pairwase effect is still the same - n=
o =20
connection.
