RSU(4)		       FreeBSD Kernel Interfaces Manual			RSU(4)

NAME
     rsu -- Realtek RTL8188SU/RTL8192SU	USB IEEE 802.11b/g/n wireless network
     device

SYNOPSIS
     To	compile	this driver into the kernel, place the following lines in your
     kernel configuration file:

	   device ehci
	   device uhci
	   device ohci
	   device usb
	   device rsu
	   device wlan

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   if_rsu_load="YES"

     After you have read the license in	/usr/share/doc/legal/realtek you will
     want to add the following lines to	loader.conf(5):

	   legal.realtek.license_ack=1
	   rsu-rtl8712fw_load="YES"

DESCRIPTION
     The rsu driver supports USB 2.0 wireless network devices based on Realtek
     RTL8188SU,	RTL8191SU and RTL8192SU	chipsets.

     The RTL8188SU 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 RTL8191SU is a	highly integrated multiple-in, single-out (MISO)
     802.11n adapter that combines a MAC, a 1T2R capable baseband and an RF in
     a single chip.  It	operates in the	2GHz spectrum only.

     The RTL8192SU 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 rsu driver	can operate in:

     BSS mode	    Also known as infrastructure mode, this is used when asso-
		    ciating with an access point, through which	all traffic
		    passes.  This mode is the default.

     The rsu 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 communica-
     tion, due to serious weaknesses in	it.

     The rsu driver can	be configured at runtime with ifconfig(8).

FILES
     The driver	needs at least version 1.2 of the following firmware file,
     which is loaded when an interface is attached:

	   /boot/kernel/rsu-rtl8712fw.ko

HARDWARE
     The rsu driver provices support for Realtek RTL8188SU/RTL8192SU USB IEEE
     802.11b/g/n wireless network adapters, including:

	   ASUS	USB-N10
	   Belkin F7D1101 v1
	   D-Link DWA-131 A1
	   EDUP	EP-MS150N(W)
	   Hercules HWGUn-54
	   Hercules HWNUm-300
	   Planex GW-USNano
	   Sitecom WL-349 v1
	   Sitecom WL-353
	   Sweex LW154
	   TRENDnet TEW-648UB
	   TRENDnet TEW-649UB

EXAMPLES
     Join an existing BSS network (i.e., connect to an access point):

	   ifconfig wlan create	wlandev	rsu0 inet 192.168.0.20 \
	       netmask 0xffffff00

     Join a specific BSS network with network name ``my_net'':

	   ifconfig wlan create	wlandev	rsu0 ssid my_net up

     Join a specific BSS network with 64-bit WEP encryption:

	   ifconfig wlan create	wlandev	rsu0 ssid my_net \
		   wepmode on wepkey 0x1234567890 weptxkey 1 up

DIAGNOSTICS
     %s: failed	load firmware of file rsu-rtl8712fw  For some reason, the
     driver was	unable to read the microcode file from the filesystem.	The
     file might	be missing or corrupted.

     device timeout  A frame dispatched	to the hardware	for transmission did
     not complete in time.  The	driver will reset the hardware.	 This should
     not happen.

HISTORY
     The rsu driver first appeared in OpenBSD 4.9 and FreeBSD 10.0.

AUTHORS
     The rsu driver was	written	by Damien Bergamini <damien@openbsd.org> and
     ported by Rui Paulo <rpaulo@freebsd.org>.

CAVEATS
     The rsu driver does not support any of the	802.11n	capabilities offered
     by	the adapters.

FreeBSD	10.1			  May 3, 2014			  FreeBSD 10.1
