Conexant/Intersil PrismGT SoftMAC USB IEEE 802.11b/g
wireless network device
upgt* at uhub? port ?
upgt driver supports the USB 2.0
Conexant/Intersil PrismGT series wireless adapters based on the GW3887
These are the modes the
upgt driver can
upgt driver can be configured to use
Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA1 and WPA2).
WPA2 is the current encryption standard for wireless networks. It is
strongly recommended that neither WEP nor WPA1 are used as the sole
mechanism to secure wireless communication, due to serious weaknesses. WPA1
is disabled by default and may be enabled using the option
wpa1,wpa2". For standard WPA networks which use
pre-shared keys (PSK), keys are configured using the
wpakey" option. WPA-Enterprise networks
require use of the wpa_supplicant package. The
driver relies on the software 802.11 stack for both encryption and
decryption of data frames.
The driver needs a firmware file which is loaded when an interface is brought up:
A prepackaged version of the firmware can be installed using fw_update(8).
The following adapters should work:
The following example scans for available networks:
# ifconfig upgt0 scan
The following hostname.if(5) example configures upgt0 to join network “mynwid”, using WPA key “mywpakey”, obtaining an IP address using DHCP:
join mynwid wpakey mywpakey inet autoconf
upgt driver first appeared in
upgt driver was written by
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.
This driver does not support powersave mode.
