[Solved] ifconfig wlan0 scan does not show any results.

Hi,

I just now did a fresh install of FreeBSD.

Code:

$ uname -a
FreeBSD mybox.hsd1.ca.comcast.net. 8.2-RELEASE FreeBSD 8.2-RELEASE #0: Fri Feb 18 02:24:46 UTC 2011     root@almeida.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386

Code:

$ pciconf -lv
...
 vendor     = 'Broadcom Corporation'
    device     = 'Broadcom Corporation Dell Wireless 1390 WLAN Mini-PCI Card (BCM4311)'
    class      = network

I installed the bwn firmware from the ports net/bwn-firmware-kmod.

But when I try to scan for the available networks:

Code:

ifconfig wlan0 up scan

, but it just returns empty results. Does not show any available networks. I tried installing wpa_gui also but does not work. Below are the files and their contents that I think might be useful. Please let me know if any other information is needed.

Here is the /etc/rc.conf file:

Code:

$ cat /etc/rc.conf 

# -- sysinstall generated deltas -- # Thu Mar  3 06:55:32 2011
# Created: Thu Mar  3 06:55:32 2011
# Enable network daemons for user convenience.
# Please make all changes to this file, not to /etc/defaults/rc.conf.
# This file now contains just the overrides from /etc/defaults/rc.conf.
hostname="mybox.hsd1.ca.comcast.net."
ifconfig_nfe0="DHCP"
inetd_enable="NO"
ipv6_enable="YES"
keymap="us.iso"
moused_enable="YES"
saver="fire"
hald_enable="YES"
dbus_enable="YES"
gdm_enable="YES"
wlans_bwn0="wlan0"
ifconfig_wlan0="WPA DHCP"

Here is the /boot/loader.conf file:

Code:

$ cat /boot/loader.conf 
nvidia_load="YES"
if_bwn_load="YES"
bwn_u4_ucode_load="YES"
wlan_scan_ap_load="YES"
wlan_scan_sta_load="YES"
wlan_wep_load="YES"
wlan_ccmp_load="YES"
wlan_tkip_load="YES"

Here is the /etc/wpa_supplicant.conf

Code:

$ cat /etc/wpa_supplicant.conf 
network={
	ssid="Espresso"
	psk="************"
}

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel

How do I fix this and connect to a network?

Thank you.
