|
|
.Sh SYNOPSIS
|
|
.Cd "atu* at uhub? port ?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for wireless network adapters based around
|
|
the Atmel at76c503, at76c503a, at76c505, and at76c505a USB chipsets.
|
|
.Pp
|
|
Supported features include 802.11 and 802.3 frames, power management, BSS,
|
|
IBSS, ad-hoc, and host-based access point mode.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver encapsulates all IP and ARP traffic as 802.11 frames, however
|
|
it can receive either 802.11 or 802.3 frames.
|
|
Transmit speed is selectable between 1Mbps fixed, 2Mbps fixed, 2Mbps
|
|
with auto fallback, 5.5Mbps, 8Mbps, or 11Mbps depending on your hardware.
|
|
.Pp
|
|
Four different radio chipsets are used along with the device, each
|
|
requiring a different firmware.
|
|
.Pp
|
|
By default, the
|
|
.Nm
|
|
driver configures the card for BSS operation (aka infrastructure
|
|
mode).
|
|
This mode requires the use of an access point (base station).
|
|
.Pp
|
|
For more information on configuring this device, see
|
|
.Xr ifconfig 8 .
|
|
.Pp
|
|
The following devices are among those supported by the
|
|
.Nm
|
|
driver:
