This driver is obsolete: it was removed from the kernel in version 2.6.35.
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.
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...
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.
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.
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.
