please advice stable Linux driver for Realtek wifi chip 8812/8821au

I have wifi usb dongle Edimax ew-7811dac and try to run it under Linux with debian kernel 4.9

When I connecting to my router zyxel giga3 with wicd I have the following error – bad password. I am sure that the password is correct

May be the problem with linux driver and its patches which I took from LE repo
