Which BSP are you using?

Which board are you using?

Do you mean all the things back to normal if not select "IEEE 802.11 for Host AP(Prism2/2.5/3 and WEP/TKIP/CCMP)" in menuconfig?

[youyong]

1、BSP version is 4.1.15-2.0.1+

2、board is iMX6DL sabresd

3、if not select "IEEE 802.11 for Host AP(Prism2/2.5/3 and WEP/TKIP/CCMP" ,it is ok,but can not support "iwlist wlan0 scan"
