0. Introduction
------------ ----- ----- ---- --- -- -
This document provides a brief overview of the features supported by the
IPW2100 driver project. The main project website, where the latest
development version of the driver can be found, is:
http://ipw2100.sourceforge.net
There you can find the not only the latest releases, but also information about
potential fixes and patches, as well as links to the development mailing list
for the driver project.
===========================
1. Release 1.1.0 Current Supported Features
---------------------------
- Managed (BSS) and Ad-Hoc (IBSS)
- WEP (shared key and open)
- Wireless Tools support
- 802.1x (tested with XSupplicant 1.0.1)
Enabled (but not supported) features:
- Monitor/RFMon mode
- WPA/WPA2
The distinction between officially supported and enabled is a reflection
on the amount of validation and interoperability testing that has been
performed on a given feature.
===========================
2. Command Line Parameters
---------------------------
If the driver is built as a module, the following optional parameters are used
by entering them on the command line with the modprobe command using this
syntax:
modprobe ipw2100 [<option>=<VAL1><,VAL2>...]
For example, to disable the radio on driver loading, enter:
modprobe ipw2100 disable=1
The ipw2100 driver supports the following module parameters:
Name Value Example:
debug 0x0-0xffffffff debug=1024
mode 0,1,2 mode=1 /* AdHoc */
channel int channel=3 /* Only valid in AdHoc or Monitor */
associate boolean associate=0 /* Do NOT auto associate */
disable boolean disable=1 /* Do not power the HW */
===========================
3. Sysfs Helper Files
---------------------------
There are several ways to control the behavior of the driver. Many of the
general capabilities are exposed through the Wireless Tools (iwconfig). There
are a few capabilities that are exposed through entries in the Linux Sysfs.
----- Driver Level ------
For the driver level files, look in /sys/bus/pci/drivers/ipw2100/
debug_level
This controls the same global as the 'debug' module parameter. For
information on the various debugging levels available, run the 'dvals'
script found in the driver source directory.
NOTE: 'debug_level' is only enabled if CONFIG_IPW2100_DEBUG is turn
on.
----- Device Level ------
For the device level files look in
/sys/bus/pci/drivers/ipw2100/{PCI-ID}/
For example:
/sys/bus/pci/drivers/ipw2100/0000:02:01.0
For the device level files, see /sys/bus/pci/drivers/ipw2100:
rf_kill
read -
0 = RF kill not enabled (radio on)
1 = SW based RF kill active (radio off)
2 = HW based RF kill active (radio off)
3 = Both HW and SW RF kill active (radio off)
write -
0 = If SW based RF kill active, turn the radio back on
1 = If radio is on, activate SW based RF kill
NOTE: If you enable the SW based RF kill and then toggle the HW
based RF kill from ON -> OFF -> ON, the radio will NOT come back on
===========================
4. Radio Kill Switch
---------------------------
Most laptops provide the ability for the user to physically disable the radio.
Some vendors have implemented this as a physical switch that requires no
software to turn the radio off and on. On other laptops, however, the switch
is controlled through a button being pressed and a software driver then making
calls to turn the radio off and on. This is referred to as a "software based
RF kill switch"
See the Sysfs helper file 'rf_kill' for determining the state of the RF switch
on your system.
===========================
5. Dynamic Firmware
---------------------------
As the firmware is licensed under a restricted use license, it can not be
included within the kernel sources. To enable the IPW2100 you will need a
firmware image to load into the wireless NIC's processors.
You can obtain these images from <http://ipw2100.sf.net/firmware.php>.
See INSTALL for instructions on installing the firmware.
===========================
6. Power Management
---------------------------
The IPW2100 supports the configuration of the Power Save Protocol
through a private wireless extension interface. The IPW2100 supports
the following different modes:
off No power management. Radio is always on.
on Automatic power management
1-5 Different levels of power management. The higher the
number the greater the power savings, but with an impact to
packet latencies.
Power management works by powering down the radio after a certain
interval of time has passed where no packets are passed through the
radio. Once powered down, the radio remains in that state for a given
period of time. For higher power savings, the interval between last
packet processed to sleep is shorter and the sleep period is longer.
When the radio is asleep, the access point sending data to the station
must buffer packets at the AP until the station wakes up and requests
any buffered packets. If you have an AP that does not correctly support
the PSP protocol you may experience packet loss or very poor performance
while power management is enabled. If this is the case, you will need
to try and find a firmware update for your AP, or disable power
management (via `iwconfig eth1 power off`)
To configure the power level on the IPW2100 you use a combination of
iwconfig and iwpriv. iwconfig is used to turn power management on, off,
and set it to auto.
iwconfig eth1 power off Disables radio power down
iwconfig eth1 power on Enables radio power management to
last set level (defaults to AUTO)
iwpriv eth1 set_power 0 Sets power level to AUTO and enables
power management if not previously
enabled.
iwpriv eth1 set_power 1-5 Set the power level as specified,
enabling power management if not
previously enabled.
You can view the current power level setting via:
iwpriv eth1 get_power
It will return the current period or timeout that is configured as a string
in the form of xxxx/yyyy (z) where xxxx is the timeout interval (amount of
time after packet processing), yyyy is the period to sleep (amount of time to
wait before powering the radio and querying the access point for buffered
packets), and z is the 'power level'. If power management is turned off the
xxxx/yyyy will be replaced with 'off' -- the level reported will be the active
level if `iwconfig eth1 power on` is invoked.
===========================
7. Support
---------------------------
For general development information and support,
go to:
http://ipw2100.sf.net/
The ipw2100 1.1.0 driver and firmware can be downloaded from:
http://support.intel.com
For installation support on the ipw2100 1.1.0 driver on Linux kernels
2.6.8 or greater, email support is available from:
http://supportmail.intel.com

---help---
A driver for the Intel PRO/Wireless 2100 Network
Connection 802.11b wireless network adapter.
See <file:Documentation/networking/README.ipw2100> for information on
the capabilities currently enabled in this driver and for tips
for debugging issues and problems.
In order to use this driver, you will need a firmware image for it.
You can obtain the firmware from
<http://ipw2100.sf.net/>. Once you have the firmware image, you
will need to place it in /etc/firmware.
You will also very likely need the Wireless Tools in order to
configure your card:
<http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
If you want to compile the driver as a module ( = code which can be
inserted in and remvoed from the running kernel whenever you want),
say M here and read <file:Documentation/modules.txt>. The module
will be called ipw2100.ko.
config IPW2100_PROMISC
bool "Enable promiscuous mode"
depends on IPW2100
---help---
Enables promiscuous/monitor mode support for the ipw2100 driver.
With this feature compiled into the driver, you can switch to
promiscuous mode via the Wireless Tool's Monitor mode. While in this
mode, no packets can be sent.
config IPW_DEBUG
bool "Enable full debugging output in IPW2100 module."
depends on IPW2100
---help---
This option will enable debug tracing output for the IPW2100.
This will result in the kernel module being ~60k larger. You can
control which debug output is sent to the kernel log by setting the
value in
/sys/bus/pci/drivers/ipw2100/debug_level
This entry will only exist if this option is enabled.
If you are not trying to debug or develop the IPW2100 driver, you
most likely want to say N here.
