    --> Try again and look into /var/log/messages and the wvdial and pppd man pages for more information.

    --> Auto Reconnect will be attempted in 40 seconds

    And my wvdial.conf looks like this:

    Init1 = AT + CGDCONT=1, "IP", "bredband.tre.se"

    Modem Type = USB Modem

    Phone = *99#

    Baud = 460800

    Pin = 7702

    This is the lsusb output: Code:

    Bus 001 Device 004: ID 0bdb:1902 Ericsson Business Mobile Networks BV F3507g v2 Mobile Broadband Module

    I've changed the wvdial.config several times with no success and if i change Init1 to: Code:

    Init1 = ATZ

    Init2 = AT + CGDCONT=1, "IP", "bredband.tre.se"

    i get an error saying ATZ Error Bad init string. The usb dongle is a Huawei E372 Mobile Broadband modem.
