NAME
     upgt -- Conexant/Intersil PrismGT SoftMAC USB IEEE 802.11b/g wireless network device

SYNOPSIS
     upgt* at uhub? port ?

DESCRIPTION
     The upgt driver supports the USB 2.0 Conexant/Intersil PrismGT series wireless adapters
     based on the GW3887 chipset.

     These are the modes the upgt driver can operate in:

     BSS mode	    Also known as infrastructure mode, this is used when associating with an
		    access point, through which all traffic passes.  This mode is the default.

     monitor mode   In this mode the driver is able to receive packets without associating with
		    an access point.  This disables the internal receive filter and enables the
		    card to capture packets from networks which it wouldn't normally have access
		    to, or to scan for access points.

     The upgt driver can be configured to use Wired Equivalent Privacy (WEP) or Wi-Fi Protected
     Access (WPA-PSK and WPA2-PSK).  WPA is the de facto encryption standard for wireless net-
     works.  It is strongly recommended that WEP not be used as the sole mechanism to secure
     wireless communication, due to serious weaknesses in it.  The upgt driver relies on the
     software 802.11 stack for both encryption and decryption of data frames.

     The upgt driver can be configured at runtime with ifconfig(8) or on boot with
     ifconfig.if(5).

FILES
     The driver needs a firmware file which is loaded when an interface is brought up:

	   /libdata/firmware/upgt/upgt-gw3887

     Currently these firmware files can not be included in NetBSD base system.	Please download
     these files and put them into the above firmware directory.

     A tar archive file that includes upgt-gw3887 firmware can be found at:

	http://www.nazgul.ch/upgt/upgt-firmware-1.1.tar.gz

HARDWARE
     The following adapters should work:

	   Belkin F5D7050 (version 1000)
	   Cohiba Proto Board
	   D-Link DWL-G120 Cohiba
	   D-Link DWL-G122 rev A2
	   FSC Connect2Air E-5400 USB D1700
	   Gigaset USB Adapter 54
	   Inventel UR045G
	   IOGear GWU513
	   Linksys WUSB54AG
	   Linksys WUSB54G ver 2
	   Medion MD40900
	   Philips CPWUA054
	   SMC EZ ConnectG SMC2862W-G
	   Sagem XG703A
	   Spinnaker DUT
	   Spinnaker Proto Board
	   Thomson SpeedTouch 121g
	   Willcom / Sharp WS003SH/WS004SH smart phone internal wireless LAN

EXAMPLES
     The following ifconfig.if(5) example configures upgt0 to join whatever network is available
     on boot, using WEP key ``0x1deadbeef1'', channel 11, obtaining an IP address using
     dhcpcd(8):

	   ssid 'my network' nwkey 0x1deadbeef1 chan 11
	   dhcp

     Join an existing BSS network, ``my_net'':

	   # ifconfig upgt0 192.168.1.1 netmask 0xffffff00 nwid my_net

HISTORY
     The upgt driver first appeared in OpenBSD 4.3.  It was ported to NetBSD by FUKAUMI Naoki and
     first appeared in NetBSD 6.0.

AUTHORS
     The upgt driver was written by Marcus Glocker <mglocker@openbsd.org>.

     The hardware specification was reverse engineered by the people at http://www.prism54.org/.

BUGS
     The upgt driver just supports the USB 2.0 devices (GW3887 chipset) but not the USB 1.0
     devices containing the NET2280, ISL3880, and ISL3886 chipsets.  Some further efforts would
     be necessary to add USB 1.0 support to the driver.
