# iwn.4

`iwn` — Intel IEEE 802.11n 无线网络驱动

## 名称

`iwn`

## 概要

`要将此驱动编译进内核，请在你的内核配置文件中加入以下行：`

> device iwn device pci device wlan device firmware

`你还需要为设备选择固件。从以下选项中选择：`

> device iwn1000fw device iwn100fw device iwn105fw device iwn135fw device iwn2000fw device iwn2030fw device iwn4965fw device iwn5000fw device iwn5150fw device iwn6000fw device iwn6000g2afw device iwn6000g2bfw device iwn6050fw

`或者你可以使用`

> device iwnfw

`来包含全部。`

`或者，要在引导时以模块形式加载该驱动，请在 loader.conf(5) 中加入以下行：`

```sh
if_iwn_load="YES"
iwn1000fw_load="YES"
iwn100fw_load="YES"
iwn105fw_load="YES"
iwn135fw_load="YES"
iwn2000fw_load="YES"
iwn2030fw_load="YES"
iwn4965fw_load="YES"
iwn5000fw_load="YES"
iwn5150fw_load="YES"
iwn6000fw_load="YES"
iwn6000g2afw_load="YES"
iwn6000g2bfw_load="YES"
iwn6050fw_load="YES"
```

## 描述

`iwn` 驱动支持 `station` 和 `monitor` 模式操作。任何时候只能配置一个虚拟接口。有关配置此设备的更多信息，请参见 [ifconfig(8)](/man/man8/ifconfig.8.md)。

此驱动需要使用 `iwnfw` 模块构建的固件才能工作。

## 实例

加入现有 BSS 网络（即连接到接入点）：

```sh
# ifconfig wlan create wlandev iwn0 inet 192.168.0.20 e
    netmask 0xffffff00
```

加入网络名称为 `my_net` 的特定 BSS 网络：

```sh
# ifconfig wlan create wlandev iwn0 ssid my_net up
```

加入使用 64 位 WEP 加密的特定 BSS 网络：

```sh
# ifconfig wlan create wlandev iwn0 ssid my_net e
	wepmode on wepkey 0x1234567890 weptxkey 1 up
```

加入使用 128 位 WEP 加密的特定 BSS 网络：

```sh
# ifconfig wlan create wlandev iwn0 wlanmode adhoc ssid my_net e
    wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
```

## 诊断

* iwn%d: device timeout 驱动将重置硬件。这不应发生。
* iwn%d: firmware error 板载微控制器因某种原因崩溃。驱动将重置硬件。这不应发生。
* iwn%d: timeout waiting for firmware initialization to complete 板载微控制器未能及时初始化。这不应发生。
* iwn%d: could not load firmware image '%s' 驱动无法使用 [firmware(9)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man9/firmware.9.md) 子系统加载固件映像。请验证 [iwnfw(4)](/man/man4/iwnfw.4.md) 固件模块存在。
* iwn%d: could not load boot firmware 尝试将引导固件映像上传到板载微控制器失败。这不应发生。
* iwn%d: could not load microcode 尝试将微代码映像上传到板载微控制器失败。这不应发生。
* iwn%d: could not load main firmware 尝试将主固件映像上传到板载微控制器失败。这不应发生。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/iwn.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
