INTRODUCTION
This document describes how to set up and connect to the Internet using a Sprint
Wireless Modem on the Linux platform using open source software packages.
Please note that this document is provided to guide current Linux users to be able to use
Sprint Wireless Modems on any graphical Linux distribution, however, the setup instructions
in this document has been tested with Ubuntu Linux 6.10. For setup on other Linux
distributions, you should still be able to follow the instructions after you download and
install the necessary software packages outlined below. Instructions in this document are
only meant to guide the user and its information may change at any time.
REQUIREMENTS
Before you can connect to the Sprint Wireless Broadband network, you will need the
following:
•
Wireless modem that has been activated on a Windows machine. The modem should
be associated with an account with Sprint.
•
Linux installation such as Ubuntu Linux 6.10, Knoppix live CD, OpenSuSe 10.1 or
later, or Fedora Core/Redhat Linux 6 or later.
•
Linux installation should be running Kernel 2.6.x.x or later.
•
KPPP Modem Dialing software application.
KNOWN LIMITATIONS
•
System/User can not monitor card status, ie, software does not show information
about signal strengths, network service type, and connectivity status. The only
network indication available is by wireless card LED that shows whether the card is in
a Sprint coverage area (Solid ) or transmitting data (flashing).
•
Card updates (PRL, firmware and activation) features are not available. This can be
done on a Windows machine at least for the activation of the device.
•
Maximum connection speed is limited by the current generic usbserial driver to
approximately less than 500kbps.
•
Driver loading is done on the command line (can be automated by adding the
commands to a startup script that is run at boot time).

SETTING UP YOUR SYSTEM
1. This setup assumes that you have installed the usbserial driver distributed on your
Linux CD according to the instructions in the driver installation readme file. Ubuntu
has this setup by default.
2. Open an xterm window unload the usbserial driver by entering (you will be required
to enter the root password after entering this command):
“sudo modprobe –r usbserial”
After unloading the USB driver you should be returned to the command prompt.
3. On the terminal, load the driver to match your card Vendor ID and product ID.
Please lookup the proper product ID in Table 1.
“sudo modprobe usbserial vendor=[vendorID] product=[prodID]”
Where prodID is the proper product ID that corresponds to your modem card in
Table 1. Although it is not necessary to verify the result of running the command
above, but if you want to be sure that the driver is now associated with your card.
Plug in your card to the computer and make sure you have power then run the
following on the command-line:
“sudo dmesg|grep –i ttyUSB”
You should see something like:
usb 5-1: generic converter now attached to ttyUSB0
usb 5-1: generic converter now attached to ttyUSB1
Now the driver has been loaded and validated you need to setup the dialer.

With the EVDO device installed in another terminal window you can also confirm you have setup the
correct the vendor and product ID's by issuing the “lsusb” command.
4. Make sure you have a working connection to the internet. It is recommended that
you have an Ethernet connection in order to download the necessary packages for
this setup. You can verify your computer’s connection to the internet using one or
both of the following commands, separately:
“ifconfig”: You should see eth0 interface for a wired Ethernet interface
connection with an acquired IP address, or you use the command:
“ping” “the name of your favorite web site without quotes”
INSTALLING PPP PACKAGES
5. Download a few packages: Please note that the instructions in this section describe
the procedure for installing the necessary software packages on Ubuntu Linux 6.10.

CONNECTING USING YOUR WIRELESS CONNECTION
In this section, you will start a ppp connection to the network.
1. If KPPP is not launched, start KPPP from the Application/Internet menu.
2. In the KPPP window, select the connection you have set up according to the
instructions above. We suggested naming the connection as “EVDO Connection” for
simplicity. This connection name should be shown in the “Connect to” drop down list
of KPPP. Enter “user” as the Login ID and “user” as the Password as shown in Figure
11 below. On EVDO cards, any Login ID and Password will work since they are not
required by the card but the fields have to be filled in with values to prevent KPPP
from reporting an error.

SETTING UP PPP USING WVDIAL
Now that we have shown you how to setup a connection using KPPP below is another
method for those who are more comfortable with Command Line Interface (CLI). You will
still need to perform steps 2-3 so that your device can be recognized by the OS. This also
assumes you have already downloaded wvdial (pronounced Weave Dial) and installed on
your current Linux distribution. This is available by default in Ubuntu. After that you will
need to run the following steps.
Open a terminal window and type the following:
“sudo wvdialconf”
This file is typically located in /etc/ppp/peers/
This will scan for available modems and create a basic configuration file called wvdial.conf.
After running the command above you will need to modify the “/etc/wvdial.conf” file using your
favorite text editor. I chose “sudo gedit wvdial.conf”
Below is a sample wvdial.conf file:
[Dialer Defaults]
Modem = /dev/ttyUSB0
Baud = 460800
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0
&C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = USB Modem
Phone = #777
Username = ‘’
Password = ‘’
Carrier Check = no
Stupid Mode = yes
Notes: You don't need a username or password to initiate
the ppp link.
Also, you need to disable the carrier check and enable
"Stupid Mode", which makes wvdial skip any detection and
just launch pppd.

- 21 -
To dial out simply type “wvdial” or “sudo wvdial” depending on your distribution version.
You will need to keep this window open during your connection and you can disconnect by
simply hitting “CTRL-C”. Below is a sample.
# wvdial
--> WvDial: Internet dialer version 1.56
--> Initializing modem.
--> Sending: ATZ

USING DATA DEVICES WITH AUTO-INSTALL CD
Working with devices that have multiple functions can sometimes be tricky and requires a
few extra steps. For devices that support internal memory that is often seen as a CD drive
users can often install automatically for Windows systems. This is not the case for Linux.
When the device is inserted, the auto-install CDROM will be mounted and will open up a file
browser window as shown in Figure 17 using Ubuntu Live CD. Auto-install is specific to
certain multifunction devices such as the Novatel U727 and Sierra 597 modems. In order to
be able to use the modem to establish communication, you should right-click on the CDROM
drive, as highlighted in the Figure below and select “Eject” from the context menu to
unmount and eject.
Figure 17. Auto-Install CDROM of the Sprint modem is mounted and launches file browser
automatically.
On distributions that do not have the capability to mount CDROM automatically, the
command line interface (also known as the Linux Shell) can be used to eject the auto-install
CDROM using the following command:
sudo eject /dev/cdrom
NOTE:
CDROM device special file is allocated dynamically. It could be /dev/sr0, or /dev/sr1 …etc.
Yours may vary. For my test I used /cdrom.
© 2008, Sprint. All rights reserved.
- 23 -
Assuming that “cdrom” is the device special file associated with the auto-install CDROM that
needs to be ejected. Once ejected the device should change to Modem and Storage mode.
USING DEVICES WITH MICRO SD STORAGE CAPABILITY
As mentioned above multifunction devices often require several steps to get access to the
modem or mass storage. In the example below using a U727 once you eject the CD the
device will change to modem and storage mode. If the micro SD storage card is inserted in
the SD slot of the modem, file browser will launch automatically to show the SD card drive
as show in Figure 18 below. In addition, the SD card drive will be shown as an icon on the
desktop as shown in Figure 19.
Figure 18. The micro SD card mounted automatically as a usbdisk drive on Ubuntu Linux.

- 24 -
Figure 19. The SD drive icon is shown on Ubuntu desktop.
On certain Linux distributions that do not have the capability to mount CDROM
automatically, the command line interface (also known as the Linux Shell) can be used to
mount the micro SD card on the system using the following command:
sudo mount /dev/sdb0 /media/disk
Assuming that /media/disk is an empty directory available for mounting, and that sdb0 is
the device special file associated with the micro SD storage card.
Once the device has switched to Modem and Storage mode you should now be able to
configure the device to be recognized by the Linux OS as was mentioned in the “Setting up
your system” steps 1-3 above. Once the device is recognized by the device you should be
able to connect with KPPP.

WORKING WITH MULTIFUNCTIONAL DEVICES
Many devices now support multiple modes of operation such as CD, Mass Storage and
Modem mode. If you are using one of these types of devices you may want to follow the
steps below to make sure you have your configuration setup correctly.

Device changes to mass storage mode and browser opens to my MicroSD drive
Type “sudo dmesg|grep –i ttyUSB”to confirm the driver is loaded
Launch KPPP
Connect
Sierra
Sierra TRU-Install devices require a kernel patch to work correctly. In order for TRU-install
devices to be recongnized you must be running kernel 2.6.24 or above.
You can check your kernel version by using the following command “uname –r”. This can
also be validated by checking in the source directory by performing a “ls /usr/src”.
To download the latest kernel you can vist the http://www.kernel.org/
If your kernel is not updated to the correct version after a eject of the CD the Sierra TRUinstall devices will indicate a product ID=0FFF when you type “lsusb”
NOTE: Applying a kernel upgrade can be very risky if you do not know what you are doing
or try and apply the wrong patch update. Please consult you distribution for the proper
methond of upgrading the kernel to the latest version.

TROUBLESHOOTING
Dropped connection:
In the event that the connection is lost due to any reason, a manual reconnect is required.
You can configure your Connection to automatically redial on disconnect.
DNS issues
For DNS-related issues, please verify entries in /etc/resolv.conf file. Please refer to your
Linux distribution’s user manual for more information about fixing this problem.
Startup scripts
Currently everytime the Laptop/PC reboots steps #2-3 need to be re-entered. If you follow
the steps below you should be able to overcome this issue.
After successfully configuring the system, you may enter the following commands in
/etc/rc.local file as root:
1. Open the file for editing, I used vi editor for simplicity in opening as root user:
“sudo vi /etc/rc.local”
or
“sudo gedit /etc/rc.local” if using Ubuntu
2. Using your editor of choice , enter the following lines . Insert the lines before exit 0,
if it pre-exists in the file:
“/sbin/modprobe –r usbserial”
“/sbin/modprobe usbserial vendor=0x1410 product=0xABCD”
Where 0xABCD is your modem’s product ID that was determined using Table 1.
3. Save the file and exit editing.
4. Enter “ls –al /etc/rc.local” and check execute permissions. If the file does not have
execute permissions (the “x” in each group shown below) similar to the following:
“-rwxr-xr-x 1 root root 390 2007-02-15 11:12 /etc/rc.local”
then enter the following command to make the rc.local file executable:
“sudo chmod a+x /etc/rc.local”
5. Reboot your machine.
You do not have to enter any configuration commands any more in the future since
/etc/rc.local will be run at the end of each multi-user runlevel (i.e., think of it as system
reboot).
