Well I have a working GRUB and now and fighting with my wireless connection.
I installed the correct drivers and the one /etc/rc.d/wlan that comes with the system is not working.
If in terminal i make:
ifconfig wlan0 up
wpa_supplicant -B -D nl80122,wext -i wlan0 -c myconfigfile
dhcpcd wlan0
The connection works fine.
If i put that in a init file in /etc/rc.d/wlan1 with the following:

#!/bin/sh
case $1 in
  start)
    /sbin/ifconfig wlan0 up
    /sbin/wpa_supplicant -B -D nl10822,wext -i wlan0 -c myconfigfile
    /sbin/dhcpcd wlan0
  ;;
  stop)
    /sbin/ifconfig wlan0 down
    ;;
  restart)
    $0 stop
    $0 stop
    ;;
  *)
    echo "usage $0 [start|stop|restart]"
    ;;
esac

I put the file on the /etc/rc.con but at start up is not working.
The other file in rc.conf related with nets is net

Any hint?

Thanks!
