--/aVve/J9H4Wl5yVO Content-Type: text/plain; charset=us-ascii Content-Disposition: inline I'm having trouble using the lagg driver with wpa_supplicant. When I boot with this standard configuration, my wifi works fine: > # Normal config. > wlans_iwn0="wlan0" > ifconfig_wlan0="WPA DHCP" > ifconfig_em0="DHCP" But when I boot with a lagg configuration, wpa_supplicant can't connect. > # Lagg config. > ifconfig_em0="up" > ifconfig_iwn0="ether 3c:97:0e:46:70:ca" > wlans_iwn0="wlan0" > ifconfig_wlan0="WPA" > cloned_interfaces="lagg0" > ifconfig_lagg0="laggproto failover laggport em0 laggport wlan0 DHCP" The system spends a full 5 minutes during boot trying to send DHCP requests before finally giving up. After boot, ifconfig shows that wlan0 has the right ssid, but the status is 'no carrier': > wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 > ether 3c:97:0e:46:70:ca > nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> > media: IEEE 802.11 Wireless Ethernet autoselect (autoselect) > status: no carrier > ssid neural_network channel 1 (2412 MHz 11g ht/40+) > regdomain FCC country US authmode WPA1+WPA2/802.11i privacy ON > deftxkey UNDEF txpower 30 bmiss 10 scanvalid 60 protmode CTS > ampdulimit 8k -amsdutx amsdurx shortgi -stbc wme roaming MANUAL > groups: wlan If I then manually kill wpa_supplicant and restart it with the same command, it works fine. > /usr/sbin/wpa_supplicant -s -B -i wlan0 -c /etc/wpa_supplicant.conf -D bsd -P /var/run/wpa_supplicant/wlan0.pid > wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 > ether 3c:97:0e:46:70:ca > nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> > media: IEEE 802.11 Wireless Ethernet MCS mode 11ng > status: associated > ssid neural_network channel 1 (2412 MHz 11g ht/40+) bssid c4:04:15:90:f5:fd > regdomain FCC country US authmode WPA2/802.11i privacy ON > deftxkey UNDEF AES-CCM 2:128-bit txpower 30 bmiss 10 scanvalid 60 > protmode CTS ampdulimit 64k ampdudensity 8 -amsdutx amsdurx shortgi > -stbc wme roaming MANUAL > groups: wlan /var/log/messages shows: > Jul 28 15:22:09 mako kernel: wlan0: link state changed to DOWN > Jul 28 15:22:09 mako kernel: lagg0: link state changed to DOWN > Jul 28 15:22:09 mako kernel: wlan0: link state changed to UP > Jul 28 15:22:09 mako kernel: lagg0: link state changed to UP > Jul 28 15:22:09 mako kernel: wlan0: link state changed to DOWN > Jul 28 15:22:09 mako kernel: lagg0: link state changed to DOWN > Jul 28 15:22:09 mako kernel: wlan0: link state changed to UP > Jul 28 15:22:09 mako kernel: lagg0: link state changed to UP > Jul 28 15:22:09 mako kernel: wlan0: link state changed to DOWN > Jul 28 15:22:09 mako kernel: lagg0: link state changed to DOWN > Jul 28 15:22:09 mako kernel: wlan0: link state changed to UP > Jul 28 15:22:09 mako kernel: lagg0: link state changed to UP > Jul 28 15:22:09 mako kernel: wlan0: link state changed to DOWN > Jul 28 15:22:09 mako kernel: lagg0: link state changed to DOWN > [snip] > Jul 28 15:22:23 mako wpa_supplicant[329]: wlan0: CTRL-EVENT-SSID-REENABLED id=2 ssid="neural_network" > Jul 28 15:22:23 mako wpa_supplicant[329]: wlan0: Trying to associate with c4:04:15:90:f5:fd (SSID='neural_network' freq=2412 MHz) > Jul 28 15:22:23 mako kernel: wlan0: link state changed to UP > Jul 28 15:22:23 mako kernel: lagg0: link state changed to UP > Jul 28 15:22:23 mako wpa_supplicant[329]: wlan0: Associated with c4:04:15:90:f5:fd > Jul 28 15:22:23 mako dhclient[533]: send_packet: No buffer space available > Jul 28 15:22:27 mako dhclient[533]: send_packet: No buffer space available > Jul 28 15:22:27 mako kernel: wlan0: link state changed to DOWN > Jul 28 15:22:27 mako kernel: lagg0: link state changed to DOWN > Jul 28 15:22:27 mako wpa_supplicant[329]: wlan0: CTRL-EVENT-DISCONNECTED bssid=c4:04:15:90:f5:fd reason=0 > Jul 28 15:22:27 mako wpa_supplicant[329]: wlan0: CTRL-EVENT-SSID-TEMP-DISABLED id=2 ssid="neural_network" auth_failures=7 duration=90 reason=CONN_FAILED > Jul 28 15:22:28 mako login: ROOT LOGIN (root) ON ttyv0 > Jul 28 15:22:31 mako dhclient[533]: send_packet: Network is down > Jul 28 15:23:06 mako last message repeated 4 times This is my hardware: > iwn0@pci0:3:0:0: class=0x028000 card=0x13118086 chip=0x00858086 rev=0x34 hdr=0x00 > vendor = 'Intel Corporation' > device = 'Centrino Advanced-N 6205 [Taylor Peak]' > class = network I know I had this working at one point on 10.2-RELEASE, but recently I've tried both 11.0-BETA2 and 12-CURRENT and get this behavior.
