.Sh NAME
.Nm rtwn
.Nd Realtek RTL8188CE PCIe IEEE 802.11b/g/n wireless network device
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device rtwn"
.Cd "device rtwnfw"
.Cd "device wlan"
.Cd "device firmware"
.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_rtwn_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 :
.Bd -literal -offset indent
legal.realtek.license_ack=1
rtwn-rtl8192cfwU_load="YES"
rtwn-rtl8192cfwU_B_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver supports PCIe wireless network devices based on the Realtek
RTL8188CE chipset.
.Pp
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.
.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.
.It monitor mode
In this mode the driver is able to receive packets without
associating with an access point.
This disables the internal receive filter and enables the card to
capture packets from networks which it wouldn't normally have access to,
or to scan for access points.
.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 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.
.Pp
The
.Nm
driver can be configured at runtime with
.Xr ifconfig 8 .
.Sh FILES
The driver needs at least version 1.0 of the following firmware files,
which are loaded when an interface is brought up:
.Pp
.Bl -tag -width Ds -offset indent -compact
.It Pa /boot/kernel/rtwn-rtl8192cfwU.ko
.It Pa /boot/kernel/rtwn-rtl8192cfwU_B.ko
.El
.Sh EXAMPLES
Join an existing BSS network (i.e., connect to an access point):
.Bd -literal -offset indent
ifconfig wlan create wlandev rtwn0 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 rtwn0 ssid my_net up"
.Pp
Join a specific BSS network with 64-bit WEP encryption:
.Bd -literal -offset indent
ifconfig wlan create wlandev rtwn0 ssid my_net \e
wepmode on wepkey 0x1234567890 weptxkey 1 up
.Ed
.Sh DIAGNOSTICS
.Bl -diag
.It "could not read firmware %s"
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.

.Sh HISTORY
The
.Nm
driver first appeared in
.Ox 5.8 .
.Sh AUTHORS
The
.Nm
driver was written by
.An -nosplit
.An Stefan Sperling Aq Mt stsp@openbsd.org
and ported by
.An Kevin Lo Aq Mt kevlo@freebsd.org .
It was based on the
.Xr urtwn 4
driver written by
.An Damien Bergamini Aq Mt damien.bergamini@free.fr .
.Sh CAVEATS
The
.Nm
driver does not support any of the 802.11n capabilities offered by the
adapters.
Additional work is required in
.Xr ieee80211 9
before those features can be supported.

.Sh NAME
.Nm rtwnfw
.Nd "Firmware Module for Realtek Wireless driver"
.Sh SYNOPSIS
To compile this module into the kernel,
place the following line in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device rtwnfw"
.Ed
.Pp
This will include three firmware images inside the kernel.
If you want to pick only the firmware image for your network adapter choose one
of the following:
.Bd -ragged -offset indent
.Cd "device rtwn-rtl8192cfwU"
.Cd "device rtwn-rtl8192cfwU_B"
.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
rtwn-rtl8192cfwU_load="YES"
rtwn-rtl8192cfwU_B_load="YES"
.Ed
.Sh DESCRIPTION
This module provides access to firmware sets for the
Realtek RTL8188CE chip based PCIe adapters.
It may be
statically linked into the kernel, or loaded as a module.
.Pp
For the loaded firmware to be enabled for use the license at
.Pa /usr/share/doc/legal/realtek.LICENSE
must be agreed to by adding the following line to
.Xr loader.conf 5 :
.Pp
.Dl "legal.realtek.license_ack=1"
