See 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 . Once you have the firmware image, you will need to place it in /lib/firmware. You will also very likely need the Wireless Tools in order to configure your card: . It is recommended that you compile this driver as a module (M) rather than built-in (Y). This driver requires firmware at device initialization time, and when built-in this typically happens before the filesystem is accessible (hence firmware will be unavailable and initialization will fail). If you do choose to build this driver into your kernel image, you can avoid this problem by including the firmware and a firmware loader in an initramfs. config IPW2100_MONITOR 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 IPW2100_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. config IPW2200 tristate "Intel PRO/Wireless 2200BG and 2915ABG Network Connection" depends on PCI && CFG80211 select WIRELESS_EXT select WEXT_PRIV select FW_LOADER select LIBIPW help A driver for the Intel PRO/Wireless 2200BG and 2915ABG Network Connection adapters.

This second interface will provide every received in radiotap format. This is useful for performing wireless network analysis while maintaining an active association. Example usage: % modprobe ipw2200 rtap_iface=1 % ifconfig rtap0 up % tethereal -i rtap0 If you do not specify 'rtap_iface=1' as a module parameter then the rtap interface will not be created and you will need to turn it on via sysfs: % echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface config IPW2200_QOS bool "Enable QoS support" depends on IPW2200 config IPW2200_DEBUG bool "Enable full debugging output in IPW2200 module." depends on IPW2200 help This option will enable low level debug tracing output for IPW2200. Note, normal debug code is already compiled in. This low level debug option enables debug on hot paths (e.g Tx, Rx, ISR) and will result in the kernel module being ~70 larger. Most users will typically not need this high verbosity debug information. If you are not sure, say N here. config LIBIPW tristate depends on PCI && CFG80211 select WIRELESS_EXT select CRYPTO select CRYPTO_MICHAEL_MIC select CRYPTO_LIB_ARC4 select CRC32 help This option enables the hardware independent IEEE 802.11 networking stack. This component is deprecated in favor of the mac80211 component. config LIBIPW_DEBUG bool "Full debugging output for the LIBIPW component" depends on LIBIPW help This option will enable debug tracing output for the libipw component. This will result in the kernel module being ~70k larger. You can control which debug output is sent to the kernel log by setting the value in /proc/net/ieee80211/debug_level For example: % echo 0x00000FFO > /proc/net/ieee80211/debug_level For a list of values you can assign to debug_level, you can look at the bit mask values in ieee80211.h If you are not trying to debug or develop the libipw component, you most likely want to say N here.
