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")
authentication type. Only WEP encryption is currently supported.
Configuration and administration can be performed through the dladm(8)
or wificonfig(8) utilities.
