Hello, I have another problem where the bwn is fully recognized and wlan0 is created but the interface doesn't scan at all: # netstat -nil Name Mtu Network Address Ipkts Ierrs Idrop Opkts Oerrs Coll bwn0 2290 <Link#1> 00:26:5e:64:be:75 0 0 0 0 0 0 # ifconfig wlan0 wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 00:26:5e:64:be:75 media: IEEE 802.11 Wireless Ethernet autoselect (autoselect) status: no carrier ssid "" channel 1 (2412 MHz 11b) country US authmode OPEN privacy OFF txpower 30 bmiss 7 scanvalid 60 bgscan bgscanintvl 300 bgscanidle 250 roam:rssi 7 roam:rate 1 wme bintval 0 # kldstat Id Refs Address Size Name 1 4 0xffffffff80100000 90b9a8 kernel 2 1 0xffffffff80c22000 28a9a bwn_v4_ucode.ko doing "ifconfig wlan0 list scan" ends up immediately without further output.
