After one day, when I came back, the system is disconnected. ifconfig says wlan0: flags=8c43<UP,BROADCAST,RUNNING,OACTIVE,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether c4:85:08:82:da:5c inet 192.168.1.110 netmask 0xffffff00 broadcast 192.168.1.255 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: IEEE 802.11 Wireless Ethernet MCS mode 11ng (autoselect) status: no carrier ssid "" channel 60 (5300 MHz 11a) country US authmode WPA1+WPA2/802.11i privacy ON deftxkey UNDEF powersavemode CAM powersavesleep 100 txpower 14 bmiss 10 mcastrate 6 mgmtrate 6 scanvalid 60 bgscan bgscanintvl 300 bgscanidle 250 roam:rssi 7 roam:rate 12 wme roaming MANUAL groups: wlan and in messages, I see Dec 22 19:28:40 pepsi kernel: [88:1f:a1:3e:9f:a9] new beacon on chan 60 (bss chan 60) "Overbreaker5G" rssi 9 Dec 22 19:28:40 pepsi kernel: [88:1f:a1:3e:9f:a9] caps 0x1511 bintval 100 erp 0x0 country [US 36-43,30 100-104,30 132-134,30 149-153,30] repeating over and over. > wpa_cli status Selected interface 'wlan0' wpa_state=SCANNING ip_address=192.168.1.110 address=c4:85:08:82:da:5c I tried the old workaround: ifconfig wlan0 mode auto wlan0: flags=8c43<UP,BROADCAST,RUNNING,OACTIVE,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether c4:85:08:82:da:5c inet 192.168.1.110 netmask 0xffffff00 broadcast 192.168.1.255 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: IEEE 802.11 Wireless Ethernet MCS (autoselect) status: no carrier ssid "" channel 60 (5300 MHz 11a) country US authmode WPA1+WPA2/802.11i privacy ON deftxkey UNDEF powersavemode CAM powersavesleep 100 txpower 14 bmiss 10 mcastrate 6 mgmtrate 6 scanvalid 60 bgscan bgscanintvl 300 bgscanidle 250 roam:rssi 7 roam:rate 12 wme roaming MANUAL groups: wlan But nothing changed. Then I tried "ifconfig wlan0 scan". I see this: Dec 22 19:30:27 pepsi kernel: wlan0: ieee80211_scanreq: flags 0x1b duration 0x7fffffff mindwell 0 maxdwell 0 nssid 0 Dec 22 19:30:27 pepsi kernel: wlan0: start_scan_locked: active scan already in progress Finally, I tried ifconfig wlan0 down; ifconfig wlan0 up, and it returns to normal: Dec 22 19:32:43 pepsi kernel: wlan0: ieee80211_cancel_scan: cancel active scan Dec 22 19:32:43 pepsi kernel: wlan0: scan_task: loop start; scandone=1 Dec 22 19:32:43 pepsi kernel: wlan0: scan_task: out Dec 22 19:32:43 pepsi kernel: wlan0: scan_task: done, [ticks 86384585, dwell min 20 scanend 2214685618] Dec 22 19:32:43 pepsi kernel: wlan0: ieee80211_cancel_scan: called; F_SCAN=0, vap=match, CANCEL=0 Dec 22 19:32:43 pepsi kernel: wlan0: ieee80211_scan_flush Dec 22 19:32:43 pepsi wpa_supplicant[412]: ioctl[SIOCS80211, op=26, val=0, arg_len=0]: Operation not supported Dec 22 19:32:43 pepsi wpa_supplicant[412]: ioctl[SIOCS80211, op=26, val=0, arg_len=0]: Operation not supported Dec 22 19:32:43 pepsi wpa_supplicant[412]: wlan0: CTRL-EVENT-TERMINATING Dec 22 19:32:43 pepsi dhclient[628]: connection closed Dec 22 19:32:43 pepsi dhclient[628]: exiting. ..... So it seems to stuck in the scan. I checked the older logs, and found that there was a firmware error.
