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.
