WiFi start script problems

23 Mar 2014

      Hello,

I've got some problems with my WiFi start script:

1. From time to time it just «looses» the connection, so I have to manually reconnect it with `/etc/rc.d/wifi restart`;
2. From time to time it doesn't reconnect on my laptop wake-up after suspend;
2. dhcpcd processes aren't properly killed, so after the days of using (and dozens of wifi restarts) I see lots of running processes with `ps ax | grep dhcpcd`.

My /etc/rc.d/wifi script is the following:

#!/bin/sh
#
# /etc/rc.d/wifi: start/stop wireless network
#

case $1 in
    start)
        # loopback
        /sbin/ip addr add 127.0.0.1/8 dev lo broadcast + scope host
        /sbin/ip link set lo up
        # wireless
        /sbin/ip link set wlan0 up
        /usr/sbin/wpa_supplicant -B -iwlan0 -c/etc/wpa.conf
        /sbin/dhcpcd -t 30 -h $HOSTNAME wlan0
        ;;
    stop)
        /sbin/dhcpcd -x
        rm -f /var/run/dhcpcd-wlan0.pid
        /sbin/ip link set lo down
        /sbin/ip addr del 127.0.0.1/8 dev lo
        /sbin/ip link set wlan0 down
        /usr/bin/killall -q /usr/sbin/wpa_supplicant
	rm -f /var/run/wpa_supplicant/wlan0
        ;;
    restart)
        $0 stop
        $0 start
        ;;
    *)
        echo "usage: $0 [start|stop|restart]"
        ;;
esac

Thanks!
