Recommandation

Use var to store your interface name :

ifce="wlan0"

# Autodetect
ifce="$(iwconfig 2>/dev/null|egrep -o wlan..?|head -n1)"

Change channel

channel=6

iwconfig $ifce channel $channel

Put in monitor mode

iwconfig $ifce mode monitor

Best way to start : airmon-ng

ifconfig $ifce down
systemctl stop NetworkManager
killall wpa_supplicant
killall -KILL wpa_supplicant
airmon-ng check kill
sleep 1
