.SH NAME
atu \- Atmel AT76C50x USB IEEE 802.11b Wireless Device Driver
.SH DESCRIPTION
.sp
.LP
The \fBatu 802.11b\fR wireless driver is a multi-threaded, loadable, clonable,
GLDv3-based STREAMS driver supporting the Atmel AT76C50x chipset-based wireless
devices.
.SS "Configuration"
.sp
.LP
The \fBatu\fR driver performs auto-negotiation to determine the data rate and
mode. Supported 802.11b data rates are 1, 2, 5.5, and 11 Mbits/sec.
.sp
.LP
The \fBatu\fR driver supports only BSS networks (also known as \fBap\fR or
\fBinfrastructure\fR networks).
.sp
.LP
\fBopen\fR (or \fBopen-system\fR) and \fBshared key\fR authentication modes are
supported. Encryption types WEP40 and WEP104 are supported.
