- 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(1M) utility.
