Unless you are crosscompiling and you - know what you are doing. - - - Depending on what rt2x00 components will be built, - some kernel configuration options are mandatory. - It does however not matter if these options are compiled - into the kernel or compiled as module. - - Kernel config option Required for component - ------------------------------------------------------------------ - # CONFIG_NET_RADIO all - # CONFIG_MAC80211 all - # CONFIG_WLAN_80211 all - # CONFIG_PCI rt2400pci, rt2500pci, rt61pci - # CONFIG_USB rt2500usb, rt73usb - # CONFIG_HOTPLUG rt61pci, rt73usb - # CONFIG_FW_LOADER rt61pci, rt73usb - # CONFIG_CRC_ITU_T rt61pci, rt73usb - # CONFIG_DEBUG_FS rt2x00 (optional, only for debug) - # CONFIG_RFKILL rt2400pci, rt2500pci, rt61pci (optional, - only for button support) - -=================== - 1.2: GCC -========= - - - For building the rt2x00 components the same gcc version is required - as was used to build your target kernel. - -=================== - 1.3: make -========= - - - The program 'make' needs to be installed on the system. There are no - further special requirements for this program. - -=============================================================================== - 2: Hardware -======================================= - -=================== - 2.1: Chipsets -========= - - Support for each Ralink wireless chipset has been split into separate drivers. - - # rt2400pci - - chipset: rt2400 - - supports: rt2460 - - bus type: PCI/PCMCIA/miniPCI - # rt2500pci - - chipset: rt2500 - - supports: rt2560 - - bus type: PCI/PCMCIA/miniPCI - # rt2500usb - - chipset: rt2570 - - supports: rt2570 - - bus type: USB - # rt61pci - - chipset: rt61 (or rt2600) - - supports: rt2561, rt2561s, rt2661 - - bus type: PCI/PCMCIA/miniPCI - # rt73usb - - chipset: rt73 - - supports: rt2571(w), rt2573, rt2671 - - bus type: USB - -=================== - 2.2: RF button -========= - - On some occasions the Ralink chipset has been built into a laptop. - If that is the case, there usually is a hardware button that controls the - radio of the wireless interface. - If you have such a hardware device, make sure you enable hardware button - support for your device in the configuration before building the rt2x00 - components. - Note: This feature requires the enabling of the rfkill driver in the kernel. - -=============================================================================== - 3: Module building & Installation -======================================= - -=================== - 3.1: Introduction -========= - - The following steps in this chapter concerning module building and - installation need to be performed for each kernel. This means that - after each kernel upgrade the modules need to be rebuild and - reinstalled in order to make them work with the new kernel. - -=================== - 3.2: Configure -========= - - Before starting to build the rt2x00 components it is recommended to look into - the 'config' file first. In this file you can configure which components of - rt2x00 should be built. And even more importantly, you can configure with - what options the components will be built. - To build all the rt2x00 drivers (with debug capabilities enabled) no changes - in the configuration file are required. For most users this would be - sufficient to start working with rt2x00. - -=================== - 3.3: Build -========= - - To build all rt2x00 components which were enabled in the configuration file - simply run (root privileges not required): - - # $ make - - All modules (.ko files) will be created in the current directory. - -=================== - 3.4: Installation -========= - - All rt2x00 modules can be installed by doing (with root privileges): - - # $ make install - - With this command all rt2x00 modules (including rfkill and d80211) will be - created in a newly created folder named 'rt2x00' inside the kernel modules - directory (usually '/lib/modules/$(uname -r)/'). - - -============================================================================== - 4: Firmware -======================================= - -=================== - 4.1: Firmware files -========= - - rt61pci and rt73usb require firmware to be available while loading the module. - The following firmware files are available for each driver: - - # rt61pci - - rt2561.bin - - rt2561s.bin - - rt2661.bin - - # rt73usb - - rt73.bin - -=================== - 4.2: Firmware installation -========= - - The latest firmware files are available in a separate .zip archive and can be - downloaded from the support page on the Ralink website at - http://www.ralinktech.com. - Note that by a high level of logic, Ralink has named their firmware for rt73 - chipsets "rt71W" with a comment that it is for the rt2571W and rt2671 devices. - For rt61pci 3 seperate firmware files are available, which one is used depends - on which RT chip is on the device. Usually it is best to install all files. - To install the firmware the firmware files need to be manually copied to the - systems firmware folder (usually '/lib/firmware/') the exact folder depends - on the distribution. When in doubt consult the distributions documentation. - -=================== - 4.3: Firmware requirements -========= - - To load firmware when the module is loaded the hotplug daemon should be - running. Make sure you either enable hotplugging manually before loading the - module, or make sure hotplugging is enabled during the system boot process. - - -============================================================================== - 5: Module loading -======================================= - -=================== - 5.1: Module load order -========= - - When the modules have been properly installed by following the installation - instructions from the previous section, the module handlers (i.e. modprobe) - will automaticly resolve all module dependencies when loading the device - specific driver. - - When loading the modules manually with insmod, you should load them in the - following order: - - # eeprom_93cx6.ko (optional, only required for pci devices) - # rt2x00lib.ko - # rt2x00pci.ko (optional, only required for pci devices) - # rt2x00usb.ko (optional, only required for usb devices) - # rt2400pci.ko (optional, only required for rt2400 support) - # rt2500pci.ko (optional, only required for rt2500 support) - # rt2500usb.ko (optional, only required for rt2570 support) - # rt61pci.ko (optional, only required for rt61 support) - # rt73usb.ko (optional, only required for rt73 support) - -=================== - 5.2: Module load options -========= - - None. - - -============================================================================== - 6: Interfaces -======================================= - -=================== - 6.1: Wireless interfaces -========= - - After loading the modules two interfaces will now be visible in ifconfig and - iwconfig, namely wmaster0 and wlan0. The first device is the so called master - device which is can be used by some userspace tools, but normally can be - ignored by the user. The second interface wlan0 is the client interface which - the user can configure. - With rt2x00 it is possible to run multiple client interfaces with - only a single device. 1 client interface can run in adhoc, managed or master - mode while a second interface can run in monitor mode at the same time. - More client interfaces can be added by issuing the following command - (with root privileges): - - # $ echo -n <name> > /sys/class/ieee80211/<dev>/add_iface - - where the variable <name> is the name of the client interface that should be - added (i.e. wlan1), and <dev> is the physical device where the new client - interface should be attached to (i.e. phy0). - -=================== - 6.2: Input interface -========= - - When the rfkill driver is being used a new input device with the name of the - device specific module where the button belongs to will have been created. - Whenever the user presses the hardware button the rfkill driver will - automatically make sure the hardware radio is being disabled or enabled - accordingly. When the user has opened the input device the radio will - not be automatically controlled, but instead the input device will - report all button events (KEY_RFKILL) to userspace where the user - could have setup script to do all the work that has to be executed. - This means that while the input device is opened, the user is responsible - for the correct behaviour. - - -============================================================================== - 7: Interface configuration -======================================= - -=================== - 7.1: Minimal configuration -========= - - - After loading the modules the interface should be configured to start - an association or work in monitor mode. The following steps are required - for a minimal configuration to associate with a non-encrypted access point. - - - Before bringing the client interface up, the working mode should be set: - - # $ iwconfig wlan0 mode managed - - - Configuration parts like essid and channel can be set before or after the - client interface has been brought up. - - - It is usually a good idea to set the essid: - - # $ iwconfig wlan0 essid myessid - - - In some situations the device also requires the channel to be manually set: - - # $ iwconfig wlan0 channel mychannel - - - To bring the client interface up: - - # $ ifconfig wlan0 up - - - After the client interface has been brought up, scanning can be performed - to check if the desired AP is being detected. - - # $ iwlist wlan0 scan - - - To start an association attempt, the AP address should be set: - - # $ iwconfig wlan0 ap mybssid - -=================== - 7.2: Configuration tools -========= - - To configure the interface several tools are possible, the most basic tools - are the wireless-tools that provide the iwconfig, iwpriv and iwlist commands. - For WPA connections the wireless-tools are not sufficient, to configure the - interface for WPA wireless network wpa_supplicant is required. - For master mode functionality it is possible to only use the wireless-tools, - but it is recommended to use hostapd instead. This tool offers the best - functionality. - For all configuration tools (wireless-tools, wpa_supplicant and hostapd) are - manuals and howto's present in the manpages or on the internet. It is adviced - to have at least read the manpages before using the tools for a better - understanding on configuring the interface. - - -============================================================================== - 8: Distribution specific notes -======================================= - -=================== - 8.1: Debian & derivatives -========= - - In some instances installing the rt2x00 drivers on debian will result - in the problem that the files are being copied into the wrong folder, - which results in the fact that the driver cannot be loaded. - Installing the drivers should be done manually in this case, - please refer to the distributions documentation regarding the proper - location of the kernel modules. - -=================== - 8.2: Fedora -========= - - Although rt2x00 contains many backward compatibility fixes to ensure - that all rt2x00 components will be able to compile and run on all - systems that meet the minimal requirements, this does not work in all - situations when the Fedora kernels are being used. - The problem lies in the fact that Fedora (like most other distributions) - heavily patch their kernel for better stability and more features. - Unlike the other distributions however, Fedora does not pay attention to - compatibility for external kernel drivers. This means that compiling rt2x00 - while using a Fedora kernel will result in compile errors regarding unknown - fields in structures or problems with function arguments. - For rt2x00 it is impossible to make all checks to support all Fedora kernel - releases. This means that when rt2x00 compilation is failing while using a - Fedora kernel we cannot give support for the compilation steps. - We recommend the user to complain to the Fedora developers when this problem - occurs. - If the user has managed to compile rt2x00 for a Fedora kernel we will - give support for possible problems while working with rt2x00. So the only - part we do not support is the building of rt2x00. - Please note that when you have edited the rt2x00 code to make it compile, - it is advised to state those changes in bugreports while reporting other - problems with rt2x00. - -=================== - 8.3: Gentoo -========= - - rt2x00 can also be found in portage, both the beta releases and the cvs tree. - Because rt2x00 is still experimental these ebuild are still masked, this means - that before you can emerge them they first have to be unmasked. - Gentoo provides various instructions on how this can be done on their website. - -=================== - 8.4: Mandriva -========= - - In some instances installing the rt2x00 drivers on Mandriva will result - in the problem that the files are being copied into the wrong folder, - which results in the fact that the driver cannot be loaded. - Installing the drivers should be done manually in this case, - please refer to the distributions documentation regarding the proper - location of the kernel modules. - - -============================================================================== - 9: Problems & Troubleshooting -======================================= - -=================== - 9.1: Debug information -========= - - When reporting problems make sure the driver has been compiled with debug - enabled. - If you have done so, the debug output can be found in the output - of 'dmesg' and also in /var/log/messages and /var/log/syslog. - -=================== - 9.2: Debugfs -========= - - rt2x00 provides several debugfs entries which can be used to help - provide more information about the interface. - To see the rt2x00 debugfs entries, debugfs should first be mounted, - to do this you should issue the following command: - - # $ mount -t debugfs none /debug - - Where /debug is the directy on which the debugfs entries should appear, - make sure this directory exists when mounting debugfs. - With the debugfs folder, the rt2x00 folder with the rt2x00 debugfs entries - will be created. Within the rt2x00 folder, each physical device will be - represented by a folder named after the interface which belongs to this - device. Within the folder the following files can be found: - - # register - - This file contains the register contents of the interface. - # eeprom - - This file contains the eeprom contents of the interface. - -=================== - 9.3: Bug reporting -========= - - When reporting a bug or problem with the rt2x00 module, - make sure you report the following information: - # How to reproduce - # RT2x00 debug output, usually found in /var/log/messages - # Module version - # Wireless card chipset, model and manufacturer - # Kernel version (i.e. 2.6.17) - # Hardware architecture (i.e. x86, AMD64, Sparc) - # rt2x00 code changes done by the user - # Anything else you may think will help us resolve the issue - - -============================================================================== - 10: Problems & Workarounds -======================================= - -=================== - 10.1: udev interface naming -========= - - In some cases when loading the rt2x00 drivers the interface names are - different from the names used in this README. This is usually caused by the - udev handler who has set some rules regarding the interface. These rules - are usually set up by the distribution and have been created especially for - for the legacy driver and their strange behavior. - To change the rules udev applies to your interface you should edit the udev - rules stored in /etc/udev/rules.d/ (exact location might be different - depending on distribution). - When editing this file, search for the line that contains something like this: - - # ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", - # SYSFS{address}=="<mac address>", NAME="<interface>" - (line has been wrapped due to max line length limit) - - Where <mac address> is the hardware address of your wireless networkcard, - and <interface> is the interface name the interface takes as soon as the - rt2x00 modules are loaded. - This line should be changed to look like: - - # ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", - # SYSFS{address}=="<mac address>", SYSFS{type}=="801", - # NAME="wmaster0" - # ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", - # SYSFS{address}=="<mac address>", NAME="wlan0" - (the 2 lines have been wrapped due to max line length limit) - - Where <mac address> is the hardware address of your wireless networkcard, - and thus should be the same as on the original line. - -=================== - 10.2: BUG - ifdown & ifup radio failure -========= - - It is a known issue (and BUG) that the driver will fail to correctly resume - its radio operations after the interface has been brought down and up again. - It is still unknown what the cause for this issue could be, besides the fact - that for some reason the device's registers have been incorrectly initialized. - This issue also has impact on the device status after a suspend/resume - operation. There is no known workaround for this yet. - - -============================================================================== - 11: TODO list -======================================= - See http://rt2x00.serialmonkey.com/wiki/index.php/Rt2x00_beta - -============================================================================== - 12: Contact us -======================================= - - - Website - # http://rt2x00.serialmonkey.com/ - # http://rt2x00.serialmonkey.com/wiki/index.php/Rt2x00_beta - - - Forums: - # http://rt2x00.serialmonkey.com/phpBB2/ - - - Mailing list: - # general: rt2400-general@lists.sourceforge.net - # developers: rt2400-devel@lists.sourceforge.net - - - Sourceforge: - # http://sourceforge.net/projects/rt2400 - |
