Hi James, Thanks for the clarification around DEL_INTERFACE/CQM, that's reassuring and makes sense! On the MAC address, yes - /sys/class/ieee80211/phy0/macaddress reports all zeros. Would you expect the wl driver to set this? n.b. I note that '[iwd]# station wlan0 show' and '# iw wlan0 link' both successfully report the MAC address for the access point.
