  400.   IMPORTANT INFORMATION BEFORE USING THIS DRIVER
  41-----------------------------------------------
  42
  43Important Notice FOR ALL USERS OR DISTRIBUTORS!!!! 
  44
  45Intel wireless LAN adapters are engineered, manufactured, tested, and
  46quality checked to ensure that they meet all necessary local and
  47governmental regulatory agency requirements for the regions that they
  48are designated and/or marked to ship into. Since wireless LANs are
  49generally unlicensed devices that share spectrum with radars,
  50satellites, and other licensed and unlicensed devices, it is sometimes
  51necessary to dynamically detect, avoid, and limit usage to avoid
  52interference with these devices. In many instances Intel is required to
  53provide test data to prove regional and local compliance to regional and
  54governmental regulations before certification or approval to use the
  55product is granted. Intel's wireless LAN's EEPROM, firmware, and
  56software driver are designed to carefully control parameters that affect
  57radio operation and to ensure electromagnetic compliance (EMC). These
  58parameters include, without limitation, RF power, spectrum usage,
  59channel scanning, and human exposure. 
  60
  61For these reasons Intel cannot permit any manipulation by third parties
  62of the software provided in binary format with the wireless WLAN
  63adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
  64patches, utilities, or code with the Intel wireless LAN adapters that
  65have been manipulated by an unauthorized party (i.e., patches,
  66utilities, or code (including open source code modifications) which have
  67not been validated by Intel), (i) you will be solely responsible for
  68ensuring the regulatory compliance of the products, (ii) Intel will bear
  69no liability, under any theory of liability for any issues associated
  70with the modified products, including without limitation, claims under
  71the warranty and/or issues arising from regulatory non-compliance, and
  72(iii) Intel will not provide or be required to assist in providing
  73support to any third parties for such modified products.  
  74
  75Note: Many regulatory agencies consider Wireless LAN adapters to be
  76modules, and accordingly, condition system-level regulatory approval
  77upon receipt and review of test data documenting that the antennas and
  78system configuration do not cause the EMC and radio operation to be
  79non-compliant.
  80
  81The drivers available for download from SourceForge are provided as a 
  82part of a development project.  Conformance to local regulatory 
  83requirements is the responsibility of the individual developer.  As 
  84such, if you are interested in deploying or shipping a driver as part of 
  85solution intended to be used for purposes other than development, please 
  86obtain a tested driver from Intel Customer Support at:

  911.   Introduction
  92-----------------------------------------------
  93The following sections attempt to provide a brief introduction to using 
  94the Intel(R) PRO/Wireless 2915ABG Driver for Linux.
  95
  96This document is not meant to be a comprehensive manual on 
  97understanding or using wireless technologies, but should be sufficient 
  98to get you moving without wires on Linux.
  99
 100For information on building and installing the driver, see the INSTALL
 101file.
 102
 103
 1041.1. Overview of Features
 105-----------------------------------------------
 106The current release (1.1.2) supports the following features:
 107
 108+ BSS mode (Infrastructure, Managed)
 109+ IBSS mode (Ad-Hoc)
 110+ WEP (OPEN and SHARED KEY mode)
 111+ 802.1x EAP via wpa_supplicant and xsupplicant
 112+ Wireless Extension support 
 113+ Full B and G rate support (2200 and 2915)
 114+ Full A rate support (2915 only)
 115+ Transmit power control
 116+ S state support (ACPI suspend/resume)
 117
 118The following features are currently enabled, but not officially
 119supported:
 120
 121+ WPA
 122+ long/short preamble support
 123+ Monitor mode (aka RFMon)
 124
 125The distinction between officially supported and enabled is a reflection 
 126on the amount of validation and interoperability testing that has been
 127performed on a given feature. 
 128

 130
 1311.2. Command Line Parameters
 132-----------------------------------------------
 133
 134Like many modules used in the Linux kernel, the Intel(R) PRO/Wireless
 1352915ABG Driver for Linux allows configuration options to be provided 
 136as module parameters.  The most common way to specify a module parameter 
 137is via the command line.  
 138
 139The general form is:
 140
 141% modprobe ipw2200 parameter=value
 142
 143Where the supported parameter are:
 144
 145  associate
 146        Set to 0 to disable the auto scan-and-associate functionality of the
 147        driver.  If disabled, the driver will not attempt to scan 
 148        for and associate to a network until it has been configured with 
 149        one or more properties for the target network, for example configuring 
 150        the network SSID.  Default is 0 (do not auto-associate)
 151        
 152        Example: % modprobe ipw2200 associate=0
