rtwn — Realtek
RTL8188CE/RTL8188EE/RTL8192CE/RTL8723AE PCIe IEEE 802.11b/g/n wireless
rtwn* at pci? port ?
rtwn driver supports PCIe wireless
network devices based on the Realtek RTL8188CE, RTL8188EE, RTL8192CE and
The RTL8188CE, RTL8188EE and RTL8723AE are highly integrated 802.11n adapters that combine a MAC, a 1T1R capable baseband and an RF in a single chip. The RTL8723AE also includes a Bluetooth 2.1/3.0/4.0 controller.
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.
These devices operate in the 2GHz spectrum only.
These are the modes the
rtwn driver can
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 driver needs at least version 1.0 of the following firmware files, which are loaded when an interface is brought up:
A prepackaged version of the firmware can be installed using fw_update(1).
The following example scans for available networks:
# ifconfig rtwn0 scan
The following hostname.if(5) example configures rtwn0 to join network “mynwid”, using WPA key “mywpakey”, obtaining an IP address using DHCP:
nwid mynwid wpakey mywpakey dhcp
rtwn driver first appeared in
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.
This driver does not support powersave mode.
