It seems to be there but doesn't appear in ifconfig. It's an HP laptop.

Code:

Code:

ifconfig wlan0 create wlandev rtwn\_pci0
# add wlan interface to /etc/rc.conf
echo ' wlans_rtwn\_pci0="wlan0" ' | grep -xFv -f /etc/rc.conf >> /etc/rc.conf     
echo ' ifconfig_wlan0="WPA DHCP" ' | grep -xFv -f /etc/rc.conf >> /etc/rc.conf

For wifi you need to create /etc/wpa_supplicant.conf file also.

Rich (BB code):

ifconfig wlan0 create wlandev rtwn\_pci0
echo ' wlans_rtwn\_pci0="wlan0" ' | grep -xFv -f /etc/rc.conf >> /etc/rc.conf
echo ' ifconfig_wlan0="WPA DHCP" ' | grep -xFv -f /etc/rc.conf >> /etc/rc.conf

"rtwn_pci0" is not correct, it must be "rtwn0".

wlandev rc.conf configuration (besides direct file edit) can be done much easier with sysrc(8):

Code:

# sysrc wlans_rtwn0="wlan0"
# sysrc ifconfig_wlan0="WPA DHCP"
