WAVELAN !!!WAVELAN NAME SYNOPSIS DESCRIPTION PARAMETERS WIRELESS EXTENSIONS PRIVATE IOCTL SPECIFIC NOTES AUTHOR SEE ALSO ---- !!NAME wavelan - AT !!SYNOPSIS __insmod wavelan_cs.o [[io=__''B,B..''__] [[ irq=__''I,I..''__] [[name=__''N,N..''__]__ !!DESCRIPTION ''wavelan'' is the low-level device driver for the NCR / AT''WaveLAN ISA__ and Digital (DEC) __!RoamAbout DS__ wireless ethernet adapter. This driver is available as a module or might be compiled in the kernel. This driver supports multiple cards in both forms (up to 4) and allocates the next available ethernet device (eth0..eth#) for each card found, unless a device name is explicitely specified (see below). This device name will be reported in the kernel log file with the MAC address, NWID and frequency used by the card. !!PARAMETERS This section apply to the module form (parameters passed on the insmod(8) command line). If the driver is included in the kernel, use the ''ether=IRQ,IO,NAME'' syntax on the kernel command line. __io__ Specify the list of base address where to search for wavelan cards (setting by dip switch on the card). If you don't specify any io address, the driver will scan 0x390 and 0x3E0 addresses, which might conflict with other hardware... __irq__ Set the list of irq that each wavelan card should use (the value is saved in permanent storage for future use). __name__ Set the list of name to be used for each wavelan cards device (name used by ifconfig(8)). !!WIRELESS EXTENSIONS Use iwconfig(8) to manipulate wireless extensions. __NWID (or domain)__ Set the network ID [[''0'' to ''FFFF''] or disable it [[''off'']. As the NWID is stored in the card Permanent Storage Area, it will be reuse at any further invocation of the driver. __Frequency __ For the 2.4GHz 2.00 Hardware, you are able to set the frequency by specifying one of the 10 defined channels (''2.412, 2.422, 2.425, 2.4305, 2.432, 2.442, 2.452, 2.460, 2.462'' or ''2.484'') or directly by its value. The frequency is changed immediately and permanentely. Frequency availability depend on the regulations... __Statistics spy__ Set a list of MAC addresses in the driver (up to 8) and get the last quality of link for each of those (see iwspy(8)). __/proc/net/wireless__ ''status'' is the status reported by the modem. ''Link quality'' reports the quality of the modulation on the air (direct sequence spread spectrum) [[max = 16]. ''Level'' and ''Noise'' refer to the signal level and noise level [[max = 64]. The ''crypt discarded packet'' and ''misc discarded packet'' counters are not implemented. !!PRIVATE IOCTL You may use iwpriv(8) to manipulate private ioctls. __Quality and Level threshold__ Enable you the define the quality and level threshold used by the modem (packet below that level are discarded). __Histogram__ This functionality allow to set a number of signal level intervals and to count the number of packets received in each of those defined intervals. This distribution might be used to calculate the mean value and standard deviation of the signal level. !!SPECIFIC NOTES This driver will fail to detect some __non NCR/ATT__ Wavelan cards. If it's your case, you must look in the source code on how to add your card to the detection routine. Some of the mentioned features are optional. You may enable to disable them by changing flags in the driver header and recompile. !!AUTHOR Bruce Janson - bruce@cs.usyd.edu.au Jean Tourrilhes - jt@hplb.hpl.hp.com (+ others - see source code for details) !!SEE ALSO wavelan_cs(4), ifconfig(8), insmod(8), iwconfig(8), iwspy(8), iwpriv(8) ----
