wifiClient scan & router channel

I have set the wifi-router to use channel 14 , then scan to find the ssid but the command result is ERROR. So, I have changed channel to channel1 and I can found target ssid.
I want to know that the router channel it affect to ‘wifi client scan’ or not? or it was about the wifi driver in wp7605 module??

and is it have any way to check ieee80211 channel?
