bug of installing 'realtek' and 'intel_iwn' as files rather then as a 'LICENSE' file in their directories. Also add obsolete entries for the older names and names that existed in head for a period of time. Suggested by: jmg X-MFC-With: r289391 MFC after: 3 weeks Sponsored by: EMC / Isilon Storage Division

.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device ehci"
|
|
.Cd "device uhci"

.Cd "device usb"
|
|
.Cd "device rsu"
|
|
.Cd "device wlan"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a module at boot time,
|
|
place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_rsu_load="YES"
|
|
.Ed
|
|
.Pp
|
|
After you have read the license in
|
|
.Pa /usr/share/doc/legal/realtek.LICENSE
|
|
you will want to add the following lines to
|
|
.Xr loader.conf 5 :

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports USB 2.0 wireless network devices based on Realtek
|
|
RTL8188SU, RTL8191SU and RTL8192SU chipsets.
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
These are the modes the
|
|
.Nm
|
|
driver can operate in:
|
|
.Bl -tag -width "IBSS-masterXX"
|
|
.It BSS mode
|
|
Also known as
|
|
.Em infrastructure
|
|
mode, this is used when associating with an access point, through
|
|
which all traffic passes.
|
|
This mode is the default.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver can be configured at runtime with
|
|
.Xr ifconfig 8 .
|
|
.Sh FILES
|
|
The driver needs at least version 1.2 of the following firmware file,
|
|
which is loaded when an interface is attached:

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

.Sh EXAMPLES
|
|
Join an existing BSS network (i.e., connect to an access point):
|
|
.Bd -literal -offset indent
|
|
ifconfig wlan create wlandev rsu0 inet 192.168.0.20 \e
|
|
netmask 0xffffff00
|
|
.Ed
|
|
.Pp
|
|
Join a specific BSS network with network name
|
|
.Dq Li my_net :
|
|
.Pp
|
|
.Dl "ifconfig wlan create wlandev rsu0 ssid my_net up"
|
|
.Pp
|
|
Join a specific BSS network with 64-bit WEP encryption:
|
|
.Bd -literal -offset indent
|
|
ifconfig wlan create wlandev rsu0 ssid my_net \e
|
|
wepmode on wepkey 0x1234567890 weptxkey 1 up
|
|
.Ed
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "%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.
|
|
.It "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.
