ODP: wpa_supplicant with hotspot 2.0 support and network manager on rtl8192fs wireless wifi

[Piotr Lobacz]

Ok i have found something. With older version of wpa_supplicant 2.6 and hostapd also 2.6 everything is working correctly. My mobile now gets connected with ap made like before. Can it be possible that newer version of wpa_supplicant/hostapd may not work correctly, with old kernel 4.4? Or maybe there is some new bug?

Temat: wpa_supplicant with hotspot 2.0 support and network manager on rtl8192fs wireless wifi

Hi all,
i have compiled wpa_supplicant 2.9 version together with network manager 1.22 on my px30 arm board. The hotspot is being made with nmcli command like this:

nmcli device wifi hotspot password 12345678 ssid softgent

and i can see that the hotspot has been put on using this command:

nmcli d show wlan0

GENERAL.DEVICE:                         wlan0

IP6.ROUTE[2]:                           dst = ff00::/8, nh = ::, mt = 256


but, if i try to connect thi this hotspot from my mobile i get an error:

So i see that the connection is being made and for some reason it fails, due to this EAPOL-Key timeout i think.
