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 urtwn"
|
|
.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_urtwn_load="YES"
|
|
.Ed
|
|
.Pp
|
|
In both cases, place the following line in
|
|
.Xr loader.conf 5
|
|
to acknowledge the firmware license (see below):

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports USB 2.0 wireless network devices based on Realtek
|
|
RTL8188CUS, RTL8188CE-VAU, RTL8188EUS, RTL8188RU and RTL8192CU chipsets.
|
|
.Pp
|
|
The RTL8188CUS and RTL8188EUS are highly integrated 802.11n adapters that
|
|
combine a MAC, a 1T1R capable baseband and an RF in a single chip.
|
|
They operate in the 2GHz spectrum only.
|
|
The RTL8188RU is a high-power variant of the RTL8188CUS.
|
|
The RTL8188CE-VAU is a PCI Express Mini Card adapter that attaches
|
|
to the USB interface.
|
|
.Pp
|
|
The RTL8192CU 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
|
|
This driver requires the firmware built with the
|
|
.Nm urtwnfw
|
|
module to work.
|
|
For the loaded firmware to be enabled for use the license at
|
|
.Pa /usr/share/doc/legal/realtek.LICENSE
|
|
must be agreed by adding the following line to
|
|
.Xr loader.conf 5 :
|
|
.Pp
|
|
.Dl "legal.realtek.license_ack=1"
|

.Sh EXAMPLES
|
|
Join an existing BSS network (i.e., connect to an access point):
|
|
.Bd -literal -offset indent
|
|
ifconfig wlan create wlandev urtwn0 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 urtwn0 ssid my_net up"
|
|
.Pp
|
|
Join a specific BSS network with 64-bit WEP encryption:
|
|
.Bd -literal -offset indent
|
|
ifconfig wlan create wlandev urtwn0 ssid my_net \e
|
|
wepmode on wepkey 0x1234567890 weptxkey 1 up

|
.Ed
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "urtwn%d: error %d, 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 "urtwn%d: 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.
