Ubuntu – Configuring Huawei E3276 modem

modemnetworkingusb-modemusb-modeswitchwvdial

I'm having trouble with my mobile broadband modem (Huawei E3276) on Ubuntu 14.04.

lsusb output:

Bus 002 Device 024: ID 12d1:1506 Huawei Technologies Co., Ltd. E398 LTE/UMTS/GSM Modem/Networkcard

When I plugged the modem in, the following appeared in /var/log/usb_modeswitch.log:

I don't understand from the log whether everything is OK or there is something wrong with the config. Anyway, the modem doesn't show up in Unity's network menu.

I found somewhere instructions to try wvdial. I edited /etc/wvdial.conf as follows:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0
Modem Type = Analog Modem
Baud = 9600
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
; Phone = <Target Phone Number>
; Password = <Your Password>
; Username = <Your Login Name>

[Dialer tele2]
Modem = /dev/ttyUSB0
Phone = *99#
Username =;
Password =;
Init1 = ATZ
Init2 = AT+CPIN=1689
Init3 = AT+CGDCONT=1,"IP","4g.tele2.ee"
Auto DNS = on

And vwdial output was as follows:

$ wvdial tele2
--> WvDial: Internet dialer version 1.61
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: AT+CPIN=1689
AT+CPIN=1689
OK
--> Sending: AT+CGDCONT=1,"IP","4g.tele2.ee"
AT+CGDCONT=1,"IP","4g.tele2.ee"
OK
--> Modem initialized.
--> Sending: ATDT*99#
--> Waiting for carrier.
ATDT*99#
CONNECT
--> Carrier detected.  Waiting for prompt.
--> Connected, but carrier signal lost!  Retrying...
--> Sending: ATDT*99#
--> Waiting for carrier.
--> Timed out while dialing.  Trying again.
--> Sending: ATDT*99#
--> Waiting for carrier.
--> Timed out while dialing.  Trying again.
--> Sending: ATDT*99#
--> Waiting for carrier.

So it appears that vwdial can use the modem, but doesn't connect to the network. Any suggestions on what might be wrong?

Edit: here's what ModemManager and NetworkManager report in syslog when I plug the device in:

Best Answer

I got my Huawei E3276 running on (K)Ubuntu 14.04.3 (and 14.04) by creating the following file:

# custom udev rules for UMTS modems
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="14fe", RUN+="/usr/sbin/usb_modeswitch -v 12d1 -p 14fe -M '55534243123456780000000000000011062000000100000000000000000000'"
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1506", RUN+="/bin/bash -c 'modprobe option && echo 12d1 1506 > /sys/bus/usb-serial/drivers/option1/new_id

I saved this as /lib/udev/rules.d/70-usb-modeswitch.rules.
