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.
