Bug Description

Binary package hint: wvdial

This error is not limited to wvdial, network-manager cannot either connect with similar errors. Wvdial however seems to give better logging information, so I'll attach log with hopefully relevant information.

I have access to a Windows machine where the device works, so it is possible to connect with it.

I have a Huawei E160E from Finnish provider Saunalahti. All the AT commands seems to go through, but when trying to connect wvdial returns NO CARRIER, and tries to connect again, never succeeding.

I have tried using both /dev/ttyUSB0 and /dev/ttyUSB1 both giving the same errors.

The wvdial.conf has been received from http://linux.fi/index.php/Wvdial#Saunalahti in to which I've added some debugging AT commands.

[Dialer defaults]
Modem = /dev/ttyUSB0
Init1 = ATZ
Init2 = ATI
Init3 = AT+GMR
Init4 = AT+CSQ
Init5 = AT^SYSINFO
Init6 = AT+COPS?
Init7 = AT+CGREG?
Init8 = AT+CGDCONT=1,"IP","internet.saunalahti"

I was having a similar issue with a Huawei E1762. It seems the modem was getting confused when wvdial starts talking to it before it's finished registering.
-> using a script to wait until the device is registered before running wvdial solved it !

Your config does not contain:

Carrier Check = off

You probably need to add that line.
