+
+Intel wireless LAN adapters are engineered, manufactured, tested, and
+quality checked to ensure that they meet all necessary local and
+governmental regulatory agency requirements for the regions that they
+are designated and/or marked to ship into. Since wireless LANs are
+generally unlicensed devices that share spectrum with radars,
+satellites, and other licensed and unlicensed devices, it is sometimes
+necessary to dynamically detect, avoid, and limit usage to avoid
+interference with these devices. In many instances Intel is required to
+provide test data to prove regional and local compliance to regional and
+governmental regulations before certification or approval to use the
+product is granted. Intel's wireless LAN's EEPROM, firmware, and
+software driver are designed to carefully control parameters that affect
+radio operation and to ensure electromagnetic compliance (EMC). These
+parameters include, without limitation, RF power, spectrum usage,
+channel scanning, and human exposure.
+
+For these reasons Intel cannot permit any manipulation by third parties
+of the software provided in binary format with the wireless WLAN
+adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
+patches, utilities, or code with the Intel wireless LAN adapters that
+have been manipulated by an unauthorized party (i.e., patches,
+utilities, or code (including open source code modifications) which have
+not been validated by Intel), (i) you will be solely responsible for
+ensuring the regulatory compliance of the products, (ii) Intel will bear
+no liability, under any theory of liability for any issues associated
+with the modified products, including without limitation, claims under
+the warranty and/or issues arising from regulatory non-compliance, and
+(iii) Intel will not provide or be required to assist in providing
+support to any third parties for such modified products.
+
+Note: Many regulatory agencies consider Wireless LAN adapters to be
+modules, and accordingly, condition system-level regulatory approval
+upon receipt and review of test data documenting that the antennas and
+system configuration do not cause the EMC and radio operation to be
+non-compliant.
+
+The drivers available for download from SourceForge are provided as a
+part of a development project. Conformance to local regulatory
+requirements is the responsibility of the individual developer. As
+such, if you are interested in deploying or shipping a driver as part of
+solution intended to be used for purposes other than development, please
+obtain a tested driver from Intel Customer Support at:

+
+
+1. Introduction
+===============
+
+The following sections attempt to provide a brief introduction to using
+the Intel(R) PRO/Wireless 2915ABG Driver for Linux.
+
+This document is not meant to be a comprehensive manual on
+understanding or using wireless technologies, but should be sufficient
+to get you moving without wires on Linux.
+
+For information on building and installing the driver, see the INSTALL
+file.
+
+
+1.1. Overview of Features
+-------------------------
+The current release (1.1.2) supports the following features:
+
++ BSS mode (Infrastructure, Managed)
++ IBSS mode (Ad-Hoc)
++ WEP (OPEN and SHARED KEY mode)
++ 802.1x EAP via wpa_supplicant and xsupplicant
++ Wireless Extension support
++ Full B and G rate support (2200 and 2915)
++ Full A rate support (2915 only)
++ Transmit power control
++ S state support (ACPI suspend/resume)
+
+The following features are currently enabled, but not officially
+supported:
+
++ WPA
++ long/short preamble support
++ Monitor mode (aka RFMon)
+
+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.
+
+
+
+1.2. Command Line Parameters
+----------------------------
+
+Like many modules used in the Linux kernel, the Intel(R) PRO/Wireless
+2915ABG Driver for Linux allows configuration options to be provided
+as module parameters. The most common way to specify a module parameter
+is via the command line.
+
+The general form is::
+
+ % modprobe ipw2200 parameter=value
+
+Where the supported parameter are:
+
+ associate
+ Set to 0 to disable the auto scan-and-associate functionality of the
+ driver. If disabled, the driver will not attempt to scan
+ for and associate to a network until it has been configured with
+ one or more properties for the target network, for example configuring
+ the network SSID. Default is 0 (do not auto-associate)
+
+ Example: % modprobe ipw2200 associate=0
+
+ auto_create
+ Set to 0 to disable the auto creation of an Ad-Hoc network
+ matching the channel and network name parameters provided.
+ Default is 1.
+
+ channel
+ channel number for association. The normal method for setting
+ the channel would be to use the standard wireless tools
+ (i.e. `iwconfig eth1 channel 10`), but it is useful sometimes
+ to set this while debugging. Channel 0 means 'ANY'
+
+ debug
+ If using a debug build, this is used to control the amount of debug
+ info is logged. See the 'dvals' and 'load' script for more info on
+ how to use this (the dvals and load scripts are provided as part
+ of the ipw2200 development snapshot releases available from the
+ SourceForge project at http://ipw2200.sf.net)
+
+ led
+ Can be used to turn on experimental LED code.
+ 0 = Off, 1 = On. Default is 1.
+
+ mode
+ Can be used to set the default mode of the adapter.
+ 0 = Managed, 1 = Ad-Hoc, 2 = Monitor
+
+
+1.3. Wireless Extension Private Methods
+---------------------------------------
+
+As an interface designed to handle generic hardware, there are certain
+capabilities not exposed through the normal Wireless Tool interface. As
+such, a provision is provided for a driver to declare custom, or
+private, methods. The Intel(R) PRO/Wireless 2915ABG Driver for Linux
+defines several of these to configure various settings.
+
+The general form of using the private wireless methods is::
+
+ % iwpriv $IFNAME method parameters
+
+Where $IFNAME is the interface name the device is registered with
+(typically eth1, customized via one of the various network interface
+name managers, such as ifrename)
+
+The supported private methods are:
+
+ get_mode
+ Can be used to report out which IEEE mode the driver is
+ configured to support. Example:
+
+ % iwpriv eth1 get_mode
+ eth1 get_mode:802.11bg (6)
+
+ set_mode
+ Can be used to configure which IEEE mode the driver will
+ support.
+
+ Usage::
+
+ % iwpriv eth1 set_mode {mode}
+
+ Where {mode} is a number in the range 1-7:
+
+ == =====================
+ 1 802.11a (2915 only)
+ 2 802.11b
+ 3 802.11ab (2915 only)
+ 4 802.11g
+ 5 802.11ag (2915 only)
+ 6 802.11bg
+ 7 802.11abg (2915 only)
+ == =====================
+
+ get_preamble
+ Can be used to report configuration of preamble length.
+
+ set_preamble
+ Can be used to set the configuration of preamble length:
+
+ Usage::
+
+ % iwpriv eth1 set_preamble {mode}
+
+ Where {mode} is one of:
+
+ == ========================================
+ 1 Long preamble only
+ 0 Auto (long or short based on connection)
+ == ========================================
+
+
+1.4. Sysfs Helper Files
+-----------------------
+
+The Linux kernel provides a pseudo file system that can be used to
+access various components of the operating system. The Intel(R)
+PRO/Wireless 2915ABG Driver for Linux exposes several configuration
+parameters through this mechanism.
+
+An entry in the sysfs can support reading and/or writing. You can
+typically query the contents of a sysfs entry through the use of cat,
+and can set the contents via echo. For example::
+
+ % cat /sys/bus/pci/drivers/ipw2200/debug_level
+
+Will report the current debug level of the driver's logging subsystem
+(only available if CONFIG_IPW2200_DEBUG was configured when the driver
+was built).
+
+You can set the debug level via::
+
+ % echo $VALUE > /sys/bus/pci/drivers/ipw2200/debug_level
+
+Where $VALUE would be a number in the case of this sysfs entry. The
+input to sysfs files does not have to be a number. For example, the
+firmware loader used by hotplug utilizes sysfs entries for transferring
+the firmware image from user space into the driver.
+
+The Intel(R) PRO/Wireless 2915ABG Driver for Linux exposes sysfs entries
+at two levels -- driver level, which apply to all instances of the driver
+(in the event that there are more than one device installed) and device
+level, which applies only to the single specific instance.
+
+
+1.4.1 Driver Level Sysfs Helper Files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For the driver level files, look in /sys/bus/pci/drivers/ipw2200/
+
+ debug_level
+ This controls the same global as the 'debug' module parameter
+
+
+
+1.4.2 Device Level Sysfs Helper Files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For the device level files, look in::
+
+ /sys/bus/pci/drivers/ipw2200/{PCI-ID}/
+
+For example:::
+
+ /sys/bus/pci/drivers/ipw2200/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/drivers/ipw2200:
+
+ 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
+
+ ucode
+ read-only access to the ucode version number
+
+ led
+ read -
+
+ == =================
+ 0 LED code disabled
+ 1 LED code enabled
+ == =================
+
+ write -
+
+ == ================
+ 0 Disable LED code
+ 1 Enable LED code
+ == ================
+
+
+ .. note::
+
+ The LED code has been reported to hang some systems when
+ running ifconfig and is therefore disabled by default.
+
+
+1.5. Supported channels
+-----------------------
+
+Upon loading the Intel(R) PRO/Wireless 2915ABG Driver for Linux, a
+message stating the detected geography code and the number of 802.11
+channels supported by the card will be displayed in the log.
+
+The geography code corresponds to a regulatory domain as shown in the
+table below.
+
+ +------+----------------------------+--------------------+
+ | | | Supported channels |
+ | Code | Geography +----------+---------+
+ | | | 802.11bg | 802.11a |
+ +======+============================+==========+=========+
+ | --- | Restricted | 11 | 0 |
+ +------+----------------------------+----------+---------+
+ | ZZF | Custom US/Canada | 11 | 8 |
+ +------+----------------------------+----------+---------+
+ | ZZD | Rest of World | 13 | 0 |
+ +------+----------------------------+----------+---------+
+ | ZZA | Custom USA & Europe & High | 11 | 13 |
+ +------+----------------------------+----------+---------+
+ | ZZB | Custom NA & Europe | 11 | 13 |
+ +------+----------------------------+----------+---------+
+ | ZZC | Custom Japan | 11 | 4 |
+ +------+----------------------------+----------+---------+
+ | ZZM | Custom | 11 | 0 |
+ +------+----------------------------+----------+---------+
+ | ZZE | Europe | 13 | 19 |
+ +------+----------------------------+----------+---------+
+ | ZZJ | Custom Japan | 14 | 4 |
+ +------+----------------------------+----------+---------+
+ | ZZR | Rest of World | 14 | 0 |
+ +------+----------------------------+----------+---------+
+ | ZZH | High Band | 13 | 4 |
+ +------+----------------------------+----------+---------+
+ | ZZG | Custom Europe | 13 | 4 |
+ +------+----------------------------+----------+---------+
+ | ZZK | Europe | 13 | 24 |
+ +------+----------------------------+----------+---------+
+ | ZZL | Europe | 11 | 13 |
+ +------+----------------------------+----------+---------+
+
+2. Ad-Hoc Networking
+=====================
+
+When using a device in an Ad-Hoc network, it is useful to understand the
+sequence and requirements for the driver to be able to create, join, or
+merge networks.
+
+The following attempts to provide enough information so that you can
+have a consistent experience while using the driver as a member of an
+Ad-Hoc network.
+
+2.1. Joining an Ad-Hoc Network
+------------------------------
+
+The easiest way to get onto an Ad-Hoc network is to join one that
+already exists.
+
+2.2. Creating an Ad-Hoc Network
+-------------------------------
+
+An Ad-Hoc networks is created using the syntax of the Wireless tool.
+
+For Example:
+iwconfig eth1 mode ad-hoc essid testing channel 2
+
+2.3. Merging Ad-Hoc Networks
+----------------------------
+
+
+3. Interaction with Wireless Tools
+==================================
+
+3.1 iwconfig mode
+-----------------
+
+When configuring the mode of the adapter, all run-time configured parameters
+are reset to the value used when the module was loaded. This includes
+channels, rates, ESSID, etc.
+
+3.2 iwconfig sens
+-----------------
+
+The 'iwconfig ethX sens XX' command will not set the signal sensitivity
+threshold, as described in iwconfig documentation, but rather the number
+of consecutive missed beacons that will trigger handover, i.e. roaming
+to another access point. At the same time, it will set the disassociation
+threshold to 3 times the given value.
+
+
+4. About the Version Numbers
+=============================
+
+Due to the nature of open source development projects, there are
+frequently changes being incorporated that have not gone through
+a complete validation process. These changes are incorporated into
+development snapshot releases.
+
+Releases are numbered with a three level scheme:
+
+ major.minor.development
+
+Any version where the 'development' portion is 0 (for example
+1.0.0, 1.1.0, etc.) indicates a stable version that will be made
+available for kernel inclusion.
+
+Any version where the 'development' portion is not a 0 (for
+example 1.0.1, 1.1.5, etc.) indicates a development version that is
+being made available for testing and cutting edge users. The stability
+and functionality of the development releases are not know. We make
+efforts to try and keep all snapshots reasonably stable, but due to the
+frequency of their release, and the desire to get those releases
+available as quickly as possible, unknown anomalies should be expected.
+
+The major version number will be incremented when significant changes
+are made to the driver. Currently, there are no major changes planned.
+
+5. Firmware installation
+========================
+
+The driver requires a firmware image, download it and extract the
+files under /lib/firmware (or wherever your hotplug's firmware.agent
+will look for firmware files)
+
+The firmware can be downloaded from the following URL:
+
+ http://ipw2200.sf.net/
+

-% echo $VALUE > /sys/bus/pci/drivers/ipw2200/debug_level
-
-Where $VALUE would be a number in the case of this sysfs entry. The
-input to sysfs files does not have to be a number. For example, the
-firmware loader used by hotplug utilizes sysfs entries for transferring
-the firmware image from user space into the driver.
-
-The Intel(R) PRO/Wireless 2915ABG Driver for Linux exposes sysfs entries
-at two levels -- driver level, which apply to all instances of the driver
-(in the event that there are more than one device installed) and device
-level, which applies only to the single specific instance.
-
-
-1.4.1 Driver Level Sysfs Helper Files
------------------------------------------------
-
-For the driver level files, look in /sys/bus/pci/drivers/ipw2200/
-
- debug_level
-
- This controls the same global as the 'debug' module parameter
-
-
-
-1.4.2 Device Level Sysfs Helper Files
------------------------------------------------
-
-For the device level files, look in
-
- /sys/bus/pci/drivers/ipw2200/{PCI-ID}/
-
-For example:
- /sys/bus/pci/drivers/ipw2200/0000:02:01.0
-
-For the device level files, see /sys/bus/pci/drivers/ipw2200:
-
- 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
-
- ucode
- read-only access to the ucode version number
-
- led
- read -
- 0 = LED code disabled
- 1 = LED code enabled
- write -
- 0 = Disable LED code
- 1 = Enable LED code
-
- NOTE: The LED code has been reported to hang some systems when
- running ifconfig and is therefore disabled by default.
-
-
-1.5. Supported channels
------------------------------------------------
-
-Upon loading the Intel(R) PRO/Wireless 2915ABG Driver for Linux, a
-message stating the detected geography code and the number of 802.11
-channels supported by the card will be displayed in the log.
-
-The geography code corresponds to a regulatory domain as shown in the
-table below.
-
- Supported channels
-Code Geography 802.11bg 802.11a
-
---- Restricted 11 0
-ZZF Custom US/Canada 11 8
-ZZD Rest of World 13 0
-ZZA Custom USA & Europe & High 11 13
-ZZB Custom NA & Europe 11 13
-ZZC Custom Japan 11 4
-ZZM Custom 11 0
-ZZE Europe 13 19
-ZZJ Custom Japan 14 4
-ZZR Rest of World 14 0
-ZZH High Band 13 4
-ZZG Custom Europe 13 4
-ZZK Europe 13 24
-ZZL Europe 11 13

-2. Ad-Hoc Networking
------------------------------------------------
-
-When using a device in an Ad-Hoc network, it is useful to understand the
-sequence and requirements for the driver to be able to create, join, or
-merge networks.
-
-The following attempts to provide enough information so that you can
-have a consistent experience while using the driver as a member of an
-Ad-Hoc network.
-
-2.1. Joining an Ad-Hoc Network
------------------------------------------------
-
-The easiest way to get onto an Ad-Hoc network is to join one that
-already exists.
-
-2.2. Creating an Ad-Hoc Network
------------------------------------------------
-
-An Ad-Hoc networks is created using the syntax of the Wireless tool.
-
-For Example:
-iwconfig eth1 mode ad-hoc essid testing channel 2
-
-2.3. Merging Ad-Hoc Networks
------------------------------------------------
-
-
-3. Interaction with Wireless Tools
------------------------------------------------
-
-3.1 iwconfig mode
------------------------------------------------
-
-When configuring the mode of the adapter, all run-time configured parameters
-are reset to the value used when the module was loaded. This includes
-channels, rates, ESSID, etc.
-
-3.2 iwconfig sens
------------------------------------------------
-
-The 'iwconfig ethX sens XX' command will not set the signal sensitivity
-threshold, as described in iwconfig documentation, but rather the number
-of consecutive missed beacons that will trigger handover, i.e. roaming
-to another access point. At the same time, it will set the disassociation
-threshold to 3 times the given value.
-
-
-4. About the Version Numbers
------------------------------------------------
-
-Due to the nature of open source development projects, there are
-frequently changes being incorporated that have not gone through
-a complete validation process. These changes are incorporated into
-development snapshot releases.
-
-Releases are numbered with a three level scheme:
-
- major.minor.development
-
-Any version where the 'development' portion is 0 (for example
-1.0.0, 1.1.0, etc.) indicates a stable version that will be made
-available for kernel inclusion.
-
-Any version where the 'development' portion is not a 0 (for
-example 1.0.1, 1.1.5, etc.) indicates a development version that is
-being made available for testing and cutting edge users. The stability
-and functionality of the development releases are not know. We make
-efforts to try and keep all snapshots reasonably stable, but due to the
-frequency of their release, and the desire to get those releases
-available as quickly as possible, unknown anomalies should be expected.
-
-The major version number will be incremented when significant changes
-are made to the driver. Currently, there are no major changes planned.
-
-5. Firmware installation
-----------------------------------------------
-
-The driver requires a firmware image, download it and extract the
-files under /lib/firmware (or wherever your hotplug's firmware.agent
-will look for firmware files)
-
-The firmware can be downloaded from the following URL:
-
- http://ipw2200.sf.net/
-
-
