urtwndriver supports USB 2.0 wireless network devices based on Realtek RTL8188CUS, RTL8188CE-VAU, RTL8188RU and RTL8192CU chipsets.
The RTL8188CUS is a highly integrated 802.11n adapter that combines a MAC, a 1T1R capable baseband and an RF in a single chip. It operates in the 2GHz spectrum only. The RTL8188RU is a high-power variant of the RTL8188CUS. The RTL8188CE-VAU is a PCI Express Mini Card adapter that attaches to the USB interface.
The RTL8192CU is a highly integrated multiple-in, multiple-out (MIMO) 802.11n adapter that combines a MAC, a 2T2R capable baseband and an RF in a single chip. It operates in the 2GHz spectrum only.
These are the modes the
urtwn driver can
urtwn 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.
A prepackaged version of the firmware, designed to be used with pkg_add(1), can be found at:
dhcp NONE NONE NONE nwkey 0x1deadbeef1 chan 11
Configure urtwn0 to join network “my_net” using WPA with passphrase “my_passphrase”:
# ifconfig urtwn0 nwid my_net wpakey my_passphrase
Join an existing BSS network, “my_net”:
# ifconfig urtwn0 192.168.1.1 netmask 0xffffff00 nwid my_net
urtwndriver first appeared in OpenBSD 4.9.

urtwndriver does not support any of the 802.11n capabilities offered by the adapters. Additional work is required in ieee80211(9) before those features can be supported.
