ppp internet not only after restart

I have configured my network to get internet from HUAWEI E3131 usb modem at start. So I have prepared special wvdial.conf and interfaces files: **wvdial.conf:** root@debian:/home/s# cat /etc/wvdial.conf [Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 Modem Type = Analog Modem Baud = 9600 New PPPD = yes Modem = /dev/ttyUSB0 ISDN = 0 [Dialer orange] Phone = *99# Username =; Password =; root@debian:/home/s# **interfaces:** root@debian:/home/s# cat /etc/network/interfaces auto lo iface lo inet loopback auto ppp0 allow-hotplug ppp0 iface ppp0 inet wvdial provider orange root@debian:/home/s# Unfortunately with this configuration the internet connection works only after restarting my debian 8. So when I turn on the pc it doesn't work but when I then restart it, it gets to work. How to make internet start at turning the pc on? It should be wvdial because I share the ppp internet connection. **edit** There is no dual boot, no Windows installation in the system.
