Atmel at76c50x 802.11B wireless
network interfaces
SYNOPSIS
atu* at uhub? port ?
DESCRIPTION
The
atu driver provides support for wireless network adapters
based around the Atmel at76c503, at76c503a, at76c505, and at76c505a USB
chipsets.
Supported features include 802.11 and 802.3 frames, power management, BSS, IBSS,
ad-hoc, and host-based access point mode.
The
atu 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.
Four different radio chipsets are used along with the device, each requiring a
different firmware.
By default, the
atu driver configures the card for BSS
operation (aka infrastructure mode). This mode requires the use of an access
point (base station).
For more information on configuring this device, see
ifconfig(8).
