RTL8187L/RTL8187B USB IEEE 802.11b/g wireless network device
urtw* at uhub? port ?
urtw driver supports USB 802.11b/g
wireless adapters based on the Realtek RTL8187L and RTL8187B.
These are the modes the
urtw driver can
urtw 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 following adapters should work:
The following example scans for available networks:
# ifconfig urtw0 scan
The following hostname.if(5) example configures urtw0 to join network “mynwid”, using WPA key “mywpakey”, obtaining an IP address using DHCP:
nwid mynwid wpakey mywpakey inet autoconf
