One more clue: I think this has to do with the order in which the OpenWRT wifi script does things: hostapd -P /var/run/wifi-phy0.pid -B /var/run/hostapd-phy0.conf hostapd_ctrl=/var/run/hostapd-phy0/wlan0 ifconfig wlan0 ifconfig wlan0 down ifconfig wlan0 hw ether 1c:af:f7:49:50:56 up ifconfig wlan0 0.0.0.0 ifconfig wlan0 ifconfig br-lan ifconfig wlan0 0.0.0.0 ifconfig wlan0 hw ether 1c:af:f7:49:50:56 up iw dev wlan0 set txpower fixed 2000 i.e. if I restart hostapd by hand the interface comes up: |[ 791.570000] br-lan: port 2(wlan0) entered disabled state |14: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc mq master br-lan state DOWN | link/ether 1c:af:f7:49:50:56 brd ff:ff:ff:ff:ff:ff |14: wlan0: <BROADCAST,MULTICAST> mtu 1500 master br-lan state DOWN | link/ether 1c:af:f7:49:50:56 |14: wlan0: <BROADCAST,MULTICAST> mtu 1500 master br-lan state DOWN | link/ether 1c:af:f7:49:50:56 |14: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc mq master br-lan state DOWN | link/ether 1c:af:f7:49:50:56 brd ff:ff:ff:ff:ff:ff |14: wlan0: <BROADCAST,MULTICAST> mtu 1500 master br-lan state DOWN | link/ether 1c:af:f7:49:50:56 |14: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq master br-lan state DOWN | link/ether 1c:af:f7:49:50:56 brd ff:ff:ff:ff:ff:ff |14: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 master br-lan state DOWN | link/ether 1c:af:f7:49:50:56 |[ 792.130000] br-lan: port 2(wlan0) entered forwarding state |[ 792.140000] br-lan: port 2(wlan0) entered forwarding state |14: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br-lan state DORMANT | link/ether 1c:af:f7:49:50:56 |14: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br-lan state DORMANT | link/ether 1c:af:f7:49:50:56 |14: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br-lan state DORMANT | link/ether 1c:af:f7:49:50:56 |14: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master br-lan state DORMANT | link/ether 1c:af:f7:49:50:56 brd ff:ff:ff:ff:ff:ff |14: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br-lan state UP | link/ether 1c:af:f7:49:50:56 |14: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master br-lan state UP | link/ether 1c:af:f7:49:50:56 brd ff:ff:ff:ff:ff:ff Then I do ifconfig wlan0 down |4: wlan0: <BROA[ 829.620000] br-lan: port 2(wlan0) entered disabled state |DCAST,MULTICAST> mtu 1500 qdisc mq master br-lan state DOWN | link/ether 1c:af:f7:49:50:56 brd ff:ff:ff:ff:ff:ff |14: wlan0: <BROADCAST,MULTICAST> mtu 1500 master br-lan state DOWN | link/ether 1c:af:f7:49:50:56 |14: wlan0: <BROADCAST,MULTICAST> mtu 1500 master br-lan state DOWN | link/ether 1c:af:f7:49:50:56 Followed by ifconfig wlan0 up |14: wlan0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq master br-lan state UP | link/ether 1c:af:f7:49:50:56 brd ff:ff:ff:ff:ff:ff |14: wlan0: <BROADCAST,MULTICAST,UP> mtu 1500 master br-lan state UP | link/ether 1c:af:f7:49:50:56 |14: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 master br-lan state DOWN | link/ether 1c:af:f7:49:50:56 |14: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq master br-lan state DOWN | link/ether 1c:af:f7:49:50:56 brd ff:ff:ff:ff:ff:ff And it stays down with NO-CARRIER.
