Hello, I've build the driver for ARM6 (RasberryPi B) using kernel version 4.4.8. The driver builds and I can install with modprobe -v 8732bu. A wlan0 interface is created after the driver loads. I want to use the wlan0 in STATION mode and when I run wpa_supplicant I get the follow message in /var/log/messages

The output shows 'start assoc' but the association it ever completes and consequently the wlan0 interface is never brought up. Is there anything that I can do to overcome this problem? i.e. is there a driver parameter that I can set when 'modprobe-ing' the driver?

Thanks

Common problems and solutions for rtl8723bu:

  1. Check/change antenna
  2. Very bad signal with AP (don't look on signal strength in most case it's a lie)
