NAME

       ath - Atheros AR52xx 802.11b/g wireless NIC driver

DESCRIPTION

       The  ath  802.11b/g   wireless	NIC  driver  is  a  multi-threaded, loadable, clonable, GLDv3-based STREAMS driver for the Atheros  AR52xx
       (AR5210/5211/5212)  chipset-based  wireless NIC.

       The ath driver functions include controller initialization, wireless 802.11b/g infrastructure network connection, WEP, frame  transmit  and
       receive, and promiscuous and multi-cast	support.

DRIVER CONFIGURATION

       The  ath driver performs auto-negotiation to determine the data rates and mode. Supported 802.11b data rates (Mbits/sec.) are 1, 2, 5.5 and
       11. Supported 802.11g data rates (Mbits/sec.) are 1, 2, 5.5, 11, 6, 9, 12, 18, 24, 36, 48 and 54.

	The ath driver supports only BSS networks (also known  as "ap" or "infrastructure" networks) and the "open" (or "opensystem")  authentica-
       tion  type.  Only   WEP	encryption  is	currently supported. Configuration and administration can be performed	through  the  dladm(1M) or
       wificonfig(1M) utilities.
