Conexant/Intersil PrismGT SoftMAC USB IEEE 802.11b/g
wireless network device
upgt* at uhub? port ?
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:
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 networks. 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).
The driver needs a firmware file which is loaded when an interface is brought up:
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:
The following adapters should work:
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
arp(4), ifmedia(4), intro(4), netintro(4), usb(4), ifconfig.if(5), ifconfig(8)
The upgt
driver first appeared in
OpenBSD 4.3. It was ported to
NetBSD by FUKAUMI Naoki and first appeared in
NetBSD 6.0.
The upgt
driver was written by
Marcus Glocker
<mglocker@openbsd.org>.
The hardware specification was reverse engineered by the people at http://lekernel.net/prism54/.
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.
