NAME
wavelan - AT&T GIS WaveLAN ISA device driver 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&T / Lucent 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 explicitly 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 fur- ther invocation of the driver. Frequency & channels 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 permanently. Frequency availability depends 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 spec- trum) [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 makes it possible 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&T/Lucent Wavelan cards. If this happens for you, 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. SEE ALSO

NAME
iwspy - Get wireless statistics from specific nodes SYNOPSIS
iwspy [interface] iwspy interface [+] DNSNAME | IPADDR | HWADDR [...] iwspy interface off iwspy interface setthr low high iwspy interface getthr DESCRIPTION
Iwspy is used to set a list of addresses to monitor in a wireless network interface and to read back quality of link information for each of those. This information is the same as the one available in /proc/net/wireless : quality of the link, signal strength and noise level. This information is updated each time a new packet is received, so each address of the list adds some overhead in the driver. Note that this functionality works only for nodes part of the current wireless cell, you can not monitor Access Points you are not associ- ated with (you can use Scanning for that) and nodes in other cells. In Managed mode, in most case packets are relayed by the Access Point, in this case you will get the signal strength of the Access Point. For those reasons this functionality is mostly useful in Ad-Hoc and Mas- ter mode. PARAMETERS
You may set any number of addresses up to 8. DNSNAME | IPADDR Set an IP address, or in some cases a DNS name (using the name resolver). As the hardware works with hardware addresses, iwspy will translate this IP address through ARP. In some case, this address might not be in the ARP cache and iwspy will fail. In those case, ping(8) this name/address and retry. HWADDR Set a hardware (MAC) address (this address is not translated & checked like the IP one). The address must contain a colon (:) to be recognised as a hardware address. + Add the new set of addresses at the end of the current list instead of replacing it. The address list is unique for each device, so each user should use this option to avoid conflicts. off Remove the current list of addresses and disable the spy functionality setthr Set the low and high signal strength threshold for the iwspy event (for drivers that support it). Every time the signal strength for any of the address monitored with iwspy goes lower than the low threshold or goes higher than the high threshold, a Wireless Event will be generated. This can be used to monitor link outages without having to run iwspy periodically. getthr Retrieve the current low and high signal strength threshold for the iwspy event. FILES
