# rtwnfw(4)

Firmware Module for Realtek Wireless driver

## NAME

**rtwnfw** – Firmware Module for Realtek Wireless driver

## SYNOPSIS

To compile this module into the kernel, place the following line in your kernel configuration file:

**device rtwnfw**

This will include all firmware images inside the kernel. If you want to pick only the firmware image for your network adapter choose one of the following:

**device rtwn-rtl8188eefw** **device rtwn-rtl8188eufw** **device rtwn-rtl8192cfwE\_B** **device rtwn-rtl8192cfwE** **device rtwn-rtl8192cfwT** **device rtwn-rtl8192cfwU** **device rtwn-rtl8192eufw** **device rtwn-rtl8812aufw** **device rtwn-rtl8821aufw**

Alternatively, to load all firmware images as a module at boot time, place the following line in [loader.conf(5)](/loader.conf/5.md):

```
rtwn-rtl8188eefw_load="YES"
rtwn-rtl8188eufw_load="YES"
rtwn-rtl8192cfwE_B_load="YES"
rtwn-rtl8192cfwE_load="YES"
rtwn-rtl8192cfwT_load="YES"
rtwn-rtl8192cfwU_load="YES"
rtwn-rtl8192eufw_load="YES"
rtwn-rtl8812aufw_load="YES"
rtwn-rtl8821aufw_load="YES"
```

## DESCRIPTION

rtwn-rtl8192cfwE and rtl8192cfwE\_B modules provide access to firmware sets for the Realtek RTL8188CE chip based PCIe adapters. rtwn-rtl8188ee module provides access to firmware sets for the Realtek RTL8188EE chip based PCIe adapters. Other modules provide access to firmware sets for the Realtek RTL8188CUS, RTL8188CE-VAU, RTL8188EUS, RTL8188RU, RTL8192CU, RTL8192EU, RTL8812AU and RTL8821AU chip based USB WiFi adapters. They may be statically linked into the kernel, or loaded as a modules.

For the loaded firmware to be enabled for use the license at */usr/share/doc/legal/realtek.LICENSE* must be agreed to by adding the following line to [loader.conf(5)](/loader.conf/5.md):

```
legal.realtek.license_ack=1
```
