RPi 2 B - Wifi EDIMAX EW-7811UAC Tethering not working

I have RPi 2 B with wifi EDIMAX EW-7811UAC, but lan to wifi tethering not working. Wifi in klient mode working fine. is it possible at all for it to work?Please help.
Thank you.

I have to try?

How can i disable or inspect if the scanning is working or whatever.
Check /etc/connman.conf if you have BackgroundScanning = false in the [GENERAL] section

I dont have any error message. I can’t save password and wifi name every time is reset to default.
