# networking.7

`networking` — 连接到网络的快速入门指南

## 名称

`networking`, `wifi`

## 描述

在以下示例中，假设我们通过 [ix(4)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man4/ix.4.md) 驱动程序找到的第一个接口连接以太网，并通过 [iwlwifi(4)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man4/iwlwifi.4.md) 驱动程序找到的第一个接口连接 Wi-Fi，不过你的硬件会有所不同。

## 实例

```sh
# dhclient ix0
```

```sh
# dhclient ue0
```

```sh
% sysctl net.wlan.devices
```

```sh
# sysrc wlans_iwlwifi0="wlan0"
```

```sh
# sysrc ifconfig_wlan0="WPA SYNCDHCP"
```

```sh
# cd /etc/
# wpa_passphrase "myssid" "mypassphrase" >> wpa_supplicant.conf
```

```sh
# service netif restart
```

```sh
% ifconfig wlan0 scan
```

```sh
# service netif stop
```

**实例 1：使用 DHCP 连接到以太网** 在第一个 Intel 10Gb 以太网接口上请求 DHCP 租约：

**实例 2：通过 USB tethering 连接到蜂窝网络** 在第一个 USB tethering 接口上请求 DHCP 租约：

**实例 3：连接到 Wi-Fi 网络** 识别你的 Wi-Fi 硬件：使用第一个 Intel Wi-Fi 适配器创建 **wlan0** 接口：将该接口设置为通过 wpa\_supplicant(8) 请求 DHCP 租约：输入 Wi-Fi 网络的详细信息：重启网络接口守护进程：

**实例 4：扫描 Wi-Fi 网络**

**实例 5：飞行模式**

## 参见

[bsdconfig(8)](/man/man8/bsdconfig.8.md), dhclient(8), [ifconfig(8)](/man/man8/ifconfig.8.md), wpa\_passphrase(8)

FreeBSD Handbook 的 Advanced Networking 章节。

## 注意事项

`SSID` 或 `passphrase` 中的 shell 特殊字符需要为 wpa\_passphrase(8) 进行转义，通常使用 `e`，详情请参阅你所使用 shell 的手册页。

停止网络接口服务也会停止内部网络。

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/man7/networking.7.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.
