IMPORTANT INFORMATION BEFORE USING THIS DRIVER +================================================= + +Important Notice FOR ALL USERS OR DISTRIBUTORS!!!! + +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: + +https://www.intel.com/support/wireless/sb/CS-006408.htm + +1. 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. + + +2. Release git-1.1.5 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. + + +3. 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 Meaning +========= ============== ============ ============================== +debug 0x0-0xffffffff debug=1024 Debug level set to 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 +========= ============== ============ ============================== + + +4. 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 + + +5. 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. + + +6. 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. + + +7. 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. + + +8.

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/ + + +6.

My web page for the development of ray_cs is at +http://web.ralinktech.com/ralink/Home/Support/Linux.html +and I can be emailed at corey@world.std.com + +The kernel driver is based on ray_cs-1.62.tgz + +The driver at my web page is intended to be used as an add on to +David Hinds pcmcia package. All the command line parameters are +available when compiled as a module. When built into the kernel, only +the essid= string parameter is available via the kernel command line. +This will change after the method of sorting out parameters for all +the PCMCIA drivers is agreed upon. If you must have a built in driver +with nondefault parameters, they can be edited in +/usr/src/linux/drivers/net/pcmcia/ray_cs.c. Searching for module_param +will find them all. + +Information on card services is available at: + + http://pcmcia-cs.sourceforge.net/ + + +Card services user programs are still required for PCMCIA devices. +pcmcia-cs-3.1.1 or greater is required for the kernel version of +the driver. + +Currently, ray_cs is not part of David Hinds card services package, +so the following magic is required. + +At the end of the /etc/pcmcia/config.opts file, add the line: +source ./ray_cs.opts +This will make card services read the ray_cs.opts file +when starting. Create the file /etc/pcmcia/ray_cs.opts containing the +following:: + + #### start of /etc/pcmcia/ray_cs.opts ################### + # Configuration options for Raylink Wireless LAN PCMCIA card + device "ray_cs" + class "network" module "misc/ray_cs" + + card "RayLink PC Card WLAN Adapter" + manfid 0x01a6, 0x0000 + bind "ray_cs" + + module "misc/ray_cs" opts "" + #### end of /etc/pcmcia/ray_cs.opts ##################### + + +To join an existing network with +different parameters, contact the network administrator for the +configuration information, and edit /etc/pcmcia/ray_cs.opts. +Add the parameters below between the empty quotes. + +Parameters for ray_cs driver which may be specified in ray_cs.opts: + +=============== =============== ============================================= +bc integer 0 = normal mode (802.11 timing), + 1 = slow down inter frame timing to allow + operation with older breezecom access + points. + +beacon_period integer beacon period in Kilo-microseconds, + + legal values = must be integer multiple + of hop dwell + + default = 256 + +country integer 1 = USA (default), + 2 = Europe, + 3 = Japan, + 4 = Korea, + 5 = Spain, + 6 = France, + 7 = Israel, + 8 = Australia + +essid string ESS ID - network name to join + + string with maximum length of 32 chars + default value = "ADHOC_ESSID" + +hop_dwell integer hop dwell time in Kilo-microseconds + + legal values = 16,32,64,128(default),256 + +irq_mask integer linux standard 16 bit value 1bit/IRQ + + lsb is IRQ 0, bit 1 is IRQ 1 etc. + Used to restrict choice of IRQ's to use. + Recommended method for controlling + interrupts is in /etc/pcmcia/config.opts + +net_type integer 0 (default) = adhoc network, + 1 = infrastructure + +phy_addr string string containing new MAC address in + hex, must start with x eg + x00008f123456 + +psm integer 0 = continuously active, + 1 = power save mode (not useful yet) + +pc_debug integer (0-5) larger values for more verbose + logging.

This is only +useful for debugging 802.11 lowlevel protocols that are not visible to +linux. If you want to watch ftp xfers, or do similar things, you +don't need to use sniffer mode. Also, some packet types are never +sent up by the card, so you will never see them (ack, rts, cts, probe +etc.) There is a simple program (showcap) included in the ray_cs +package which parses the 802.11 headers. + +Known Problems and missing features + + Does not work with non x86 + + Does not work with SMP + + Support for defragmenting frames is not yet debugged, and in + fact is known to not work. I have never encountered a net set + up to fragment, but still, it should be fixed. + + The ioctl support is incomplete. The hardware address cannot be set + using ifconfig yet. If a different hardware address is needed, it may + be set using the phy_addr parameter in ray_cs.opts. This requires + a card insertion to take effect. |
