29.Sh NAME
30.Nm rtwnfw
31.Nd "Firmware Module for Realtek Wireless driver"
32.Sh SYNOPSIS
33To compile this module into the kernel,
34place the following line in your
35kernel configuration file:
36.Bd -ragged -offset indent
37.Cd "device rtwnfw"
38.Ed
39.Pp
40This will include all firmware images inside the kernel.
41If you want to pick only the firmware image for your network adapter choose one
42of the following:
43.Bd -ragged -offset indent
44.Cd "device rtwn-rtl8188eufw"
45.Cd "device rtwn-rtl8192cfwE_B"
46.Cd "device rtwn-rtl8192cfwE"
47.Cd "device rtwn-rtl8192cfwT"
48.Cd "device rtwn-rtl8192cfwU"
49.Cd "device rtwn-rtl8192eufw"
50.Cd "device rtwn-rtl8812aufw"
51.Cd "device rtwn-rtl8821aufw"
52.Ed
53.Pp
54Alternatively, to load all firmware images as a
55module at boot time, place the following line in
56.Xr loader.conf 5 :
57.Bd -literal -offset indent
58rtwn-rtl8188eufw_load="YES"
59rtwn-rtl8192cfwE_B_load="YES"

71RTL8188CE-VAU, RTL8188EUS, RTL8188RU, RTL8192CU, RTL8192EU, RTL8812AU and
72RTL8821AU chip based USB WiFi adapters.
73They may be
74statically linked into the kernel, or loaded as a modules.
75.Pp
76For the loaded firmware to be enabled for use the license at
77.Pa /usr/share/doc/legal/realtek.LICENSE
78must be agreed to by adding the following line to
