N73 as GSM modem

with 2 comments

Information below is a summary from here, here and here.

lsusb gives me:

Bus 002 Device 003: ID 0421:0486 Nokia Mobile Phones

so then I run

sudo modprobe usbserial vendor=0x0421 product=0x0486
sudo wvdialconf
sudo gedit /etc/wvdial.conf

and each time I want to connect I run wvdial. The result is:

WvDial<*1>: WvDial: Internet dialer version 1.56
WvModem<*1>: Cannot get information for serial port.
WvDial<*1>: Initializing modem.

The pap and chap warnings can be avoided if i run sudo wvdial instead.

The problem is that after this, I still don’t seem to have connectivity, and I don’t know what else to try…

  1. To connect to Vodafone Italia, my /etc/wvdial.conf file looks like this:
    [Dialer Defaults]
    Modem = /dev/ttyACM0
    Baud = 460800
    Init1 = ATZ
    Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
    Init3 = AT+CGDCONT=,,""
    New PPPD = yes
    ISDN = 0
    Modem Type = USB Modem
    Phone = *99#

    Username = ”
    Password = ”

  2. you can do the same through gnome-ppp. press detect to find the modem, add init3 as above (init1 is invisible, probably because it’s always ATZ, and init2 is already as above), then add the phone number…
    i found that it didn’t work with an empty username and password, but i added none none and it worked…
