Ubuntu – Mobile broadband slow to be detected

11.04broadbandconnectionnetwork-manager

— UPDATE 2: a step further. I was able to solve the GSM modem enable failed: (32) SIM PIN required loop specifying the PIN in Network manager > Edit connections… > Mobile broadband > Edit > Mobile broadband > PIN.

Original question

I'm facing a pretty annoying issue with a multimode GPRS/EDGE/UMTS/HSDPA USB internet key I use for internet access, product ONDA WCDMA Technologies MSM. OS is Ubuntu Natty 11.04 64-bit.

The application asking me to enter the PIN starts only after some minutes the key is plugged in; time varies from immediately to 5 minutes and more. I try to trigger the recognition killing Network Manager applet nm-applet and restarting it, but I'm not sure it helps. I also see there is an utility called /usr/bin/modem-manager but I'm not able to run it (provided it could be useful, as man modem-manager gives nothing).

I'd like the key to be detected as soon as I plug it in, do you have any hint? I hate to say so but on Windows it takes only few seconds and the dongle is recognized (using product manufacturer dial in software).

Thanks

A maintainer of NetworkManager explained the problem using these words:

There are certain modems for which the firmware simply doesn't respond to serial setup packets sent on certain interfaces, which cause the kernel to wait for a while before timing out.

Just in case you are experiencing a similar issue I sincerely suggest you to report it on NM mailing list, they won't miss to help. I got a patch and now the device is recognized in less than 60 seconds.

And bonus, the fix will be submitted to the mainstream kernel for everyone's benefit.

Ubuntu – Ubuntu 13.04 recognizes usb mobile broadband modem as ethernet connection

Yes! This is one of the problems I have been facing and here is a possible solution. Looking at your lsusb output, I find the following:

Bus 002 Device 004: ID 19d2:1405 ZTE WCDMA Technologies MSM

This indicates that the Vendor ID is 0x19d2 and the Product ID is 0x1405. I would advise you the following steps:

(1) Create a bash script as follows. This bash script is to be run, everytime you would like to use your mobile modem CDMA connection. Let us suppose that the name of the bash script is `myModem.sh. Do this by typing:

sudo nano ~/myModem.sh

Type in the following lines here:

#!/bin/bash
sudo /sbin/modprobe usbserial vendor=0x19d2 product=0x1405

Save your script and exit from nano. Type:

sudo chmod +x ~/myModem.sh

(2) Run the following commands:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install wvdial 
sudo apt-get install usb-modeswitch usb-modeswitch-data

(4) Type the following:

sudo nano /etc/udev/rules.d/90-zte.rules

and type in the following line (it is a single line and no carriage returns please):

SUBSYSTEM=="block",SUBSYSTEM=="scsi",ATTRS{model}=="USB Storage 1405",ACTION=="add",RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x1405"

Save the file and exit from nano.

(5) Now run your bash script from your home directory:

sudo ~/myModem.sh

(6) Now we have to configure wvdial.

sudo wvdialconf /etc/wvdial.conf

This will detect the modem and create a configuration file.

(7) Edit the configuration file to adjust the setting according to your country/service provider. Especially change the dialing phone number, username and password. Do this by typing

sudo nano /etc/wvdial.conf

Remove the semicolons before the phone, username and password. The semicolons tell wvdial that these lines are commented. Save your file and exit from nano.

(8) Now create your connection. Make sure you check the Connect Automatically option.

I hope this will set your modem working.
