How do I enable monitor mode in 60 series?

Answer

Only the SU60 version supports monitor mode.

1. Load backports driver, such as below for SDIO option.

insmod compat/compat.ko
insmod net/wireless/cfg80211.ko
insmod net/mac80211/mac80211.ko
insmod drivers/net/wireless/laird/lrdmwl/lrdmwl.ko
insmod drivers/net/wireless/laird/lrdmwl/lrdmwl_sdio.ko

2. Setup interface type as monitor mode and bring it up.

iw dev wlaninterface add wlan1 type monitor
ifconfig wlan1 up

3. Use tcpdump to capture the packet as the command below.

tcpdump -i wlan1  -n -w wireless.cap
