IPwireless PCMCIA (Sentech Mywireless) *ubuntu linux howto

This page provides instructions on how to install the drivers for a Sentech MyWireless IPWireless pcmcia modem on Feisty Fawn. Currently there is two types of Mywireless IPWireless modems supplied in South Africa - PCMCIA (laptop) and USB/Ethernet (desktop).

The USB/Ethernet modems are supported out of the box using either PPPOE or the r0dent's ipw driver so i will not dwell on that here.

Now to the installation: Please ensure that you are within Sentech coverage, our if you have been using the Windows drivers then you should know your signal status already. The PCMCIA modem has two lights on it a red one that is always on and a full green or blinking green indicate good usable signal.


The installation involves building the experimental ipwireless_cs module and installing it. To do this you need the kernel headers, if you already have the kernel headers you can skip the next step.

Install kernel headers

sudo apt-get install linux-headers-$(uname -r)

Download the Driver

Please NOTE these drivers are still in the early stage of development and are not yet in the mainline kernel. They work nicely for me how ever YMMV.


You need to get :


This patch is also required to update the driver for the 2.6.20.x kernels


Extract and Patch :

 tar xjvf ipwireless_cs-2.6.19_2.6.18.tar.bz2
cd ipwireless_cs-2.6.19_2.6.18
patch -p 1 -i ../workq.patch

Compile the driver :


Install the driver :

 sudo make install

Test the driver

Insert your Mywireless IPwireless pcmcia card into the pcmcia slot, you should see the following in /var/log/syslog :

Configure dialer


Because i am using Kubuntu i used kppp to setup the connection, am sure you can use your favorite dialer to achieve the same thing.

The ipwireless_cs driver creates ttyIPWpx devices in /dev, since kppp does not list this device i created a link between /dev/ttyIPWp0 to /dev/modem0 as am already using /dev/modem for my 3G phone.

This is done using the udev system. Edit the /etc/udev/rules.d/60-symlinks.rules file and add this:

KERNEL=="ttyIPWp*",                     SYMLINK+="modem%n"

configure kppp

  • Start kppp -> configure

  • Configure -> Accounts -> New -> Manual setup -> Connection name = SENTECH -> Phone number -> Add -> *99# -> OK -> OK

  • Modems -> Device -> New -> Name = SENTECH -> Modem device = /dev/modem0

  • Modem -> Modem commands -> Initialization string 2: AT+CGDCONT=1,"PPP","sentech.co.za","username,password",0,0 -> OK

  • Select SENTECH connection and SENTECH modem and hit connect
  • Enter your username and password
  • With good coverage you should be connected in an instant

Command line PPP

These instructions are shamelessly stolen from the author of the usb IPWireless drivers page, They provided me with guide lines in setting up kppp about and am sure will help you setup any other dialer.

Create a ppp peers file /etc/ppp/peers/sentech :

lcp-echo-interval 60
lcp-echo-failure 3
connect "/usr/sbin/chat -v -f /etc/chatscripts/sentech"
mtu 1400
user "xxxxx"
maxfail 0
deflate 15

Create a chat script /etc/chatscripts/sentech :

SAY "Dialling sentech...\n"
""              \rAT
"OK-+++\c-OK"   ATH0
OK AT+CGDCONT=1,"PPP","sentech.co.za","username,password",0,0
OK ATD*99#
SAY "Waiting up to 30 seconds for connection ... "
SAY "Connected..."

Connect :

pppd call sentech
