[solved] How to stop correctly ppp0 sharing via hostapd?

Sup guys, I have one question. I'm using simple script to share internet from my 3G-modem:

#!/bin/bash
systemctl stop wicd
rfkill unblock all
systemctl start hostapd
systemctl start dnsmasq
ifconfig wlan0 192.168.0.1   # assign IP address to interface used by hostapd
sysctl net.ipv4.ip_forward=1 # enable IP forwarding
iptables -P FORWARD ACCEPT   # initialize iptables chains
iptables -P OUTPUT ACCEPT
iptables -P INPUT ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o ppp0 -j MASQUERADE # setup NAT

3G-modem connected with pppd (by "# pon 3g" command). But when I do "# poff" or suspend my netbook, connection gets off and after that I can't to up it again:

pppd[5814]: pppd 2.4.5 started by kostett, uid 0

pppd[5814]: Hangup (SIGHUP)
pppd[5814]: Modem hangup
pppd[5814]: Connection terminated.
pppd[5814]: Exit.

After reboot all works well.
So, what can I do to connect 3G-modem without reboot?

Re: [solved] How to stop correctly ppp0 sharing via hostapd?

I turned on my brains and wrote this:

[kostett@asus-sielab ~]$ cat /usr/local/bin/hostapd_endactions
#!/bin/bash

systemctl stop hostapd.service
sysctl net.ipv4.ip_forward=0
ifconfig wlan0 0.0.0.0
iptables -F
systemctl stop dnsmasq.service
systemctl start wicd.service

All works fine. Ave for me.
