Comment 6 for bug 299274

I'm also a T400 owner, with the danish provider Sonofon.

Same story, configured wvdial manually. I usually use vpn (cisco and others) via networkmanager. I'm not capable to set vpn up with the connection enabled with wvdial.

My wvdial.conf:

[Dialer Defaults]
New PPPD = yes
Stupid Mode = 1
Modem Type = USB Modem

#[Dialer PIN]
#Init1 = AT+CPIN=

[Dialer signal]
Modem = /dev/ttyUSB10
Init1 = AT+CSQ
Init2 = AT+COPS?

[Dialer gps]
Modem = /dev/ttyUSB2
Init1 = AT*E2GPSCTL=1,2,1
Init2 = AT*E2GPSNPD

[Dialer on]
Modem = /dev/ttyUSB10
Init1 = AT+CFUN=1

[Dialer off]
Modem = /dev/ttyUSB10
Init1 = AT+CFUN=4

[Dialer connect]
Modem = /dev/ttyUSB4
Init1 = AT
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT +CGDCONT=1, "IP", "internet"
