rtwn
driver supports PCIe wireless network devices
based on the Realtek RTL8188CE and RTL8192CE chipset.
The RTL8188CE 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 RTL8192CE 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 rtwn
driver can
operate in:
The rtwn
driver can be configured to use
Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA-PSK and
WPA2-PSK). WPA is the current 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 rtwn
driver can be configured at
runtime with ifconfig(8) or
on boot with
ifconfig.if(5).

rtwn
driver first appeared in
OpenBSD 5.8 and in NetBSD 8.0.
rtwn
driver was written by Stefan
Sperling ⟨stsp@openbsd.org⟩ for
OpenBSD and ported to NetBSD
by NONAKA Kimihiro ⟨nonaka@NetBSD.org⟩.
It was based on the urtwn(4)
driver written by Damien Bergamini
⟨damien.bergamini@free.fr⟩.
rtwn
driver 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.
