Connect to WiFi Using Terminal in Arch Linux and Other Distros
|
||||
======
|
||||
This quick guide explains the steps you need to set up and connect to WiFi using a terminal in Arch Linux and other distros.
|
||||
|
||||
This guide is ideal for those scenarios where you are stuck with a terminal without any GUI, and no other wired internet connectivity is available. These steps help you to manually detect the wireless card, and device and connect to the WiFi hotspot with password authentication via terminal.
|
||||
|
||||
This guide uses [iwd][1] (Net Wireless Daemon) to connect to WiFi via a terminal.
|
||||
|
||||
### Connect to WiFi Using Terminal in Arch Linux and Other Distros
|
||||
|
||||
#### 1. Setup iwd
|
||||
|
||||
The `iwd` package comes with three main modules:
|
||||
|
||||
**iwctl** : The wireless client**iwd**: The Daemon**iwmon** : Monitoring tool
|
||||
|
||||
On the terminal type –
|
||||
|
||||
```
|
||||
iwctl
|
||||
```
|
||||
|
||||
![iwctl Prompt][2]
|
||||
|
||||
If you get a command not found, then you need to download the package from [here][3].
|
||||
|
||||
So get help from any other system/laptop with an internet connection to download and install the package via mounting the USB.
|
||||
|
||||
Alternatively, if you have a USB dongle with the internet, then plugin that into your system. And install via the below commands.
|
||||
|
||||
The USB dongle should work out of the box in Arch and most Linux systems today to connect to the internet.
|
||||
|
||||
**Arch**
|
||||
|
||||
```
|
||||
pacman -S iwd
|
||||
```
|
||||
|
||||
**Debian, Ubuntu, and other similar distributions**
|
||||
|
||||
```
|
||||
sudo apt-get install iwd
|
||||
```
|
||||
|
||||
**Fedora**
|
||||
|
||||
```
|
||||
sudo dnf install iwd
|
||||
```
|
||||
|
||||
If you get an `iwctl` prompt (like below), then proceed to the next step.
|
||||
|
||||
#### 2. Configure
|
||||
|
||||
Run the below command to get your system’s **wireless device name**.
|
||||
|
||||
```
|
||||
device list
|
||||
```
|
||||
|
||||
![iwctl – device list][4]
|
||||
|
||||
To **get the list of WiFi networks**, run the below command. Replace `wlan0` with your device name on the below command and all the following commands.
|
||||
|
||||
```
|
||||
station wlan0 get-networks
|
||||
```
|
||||
|
||||
![iwctl – available networks][5]
|
||||
|
||||
The command gives you the list of available WiFi network with security type and signal strength.
|
||||
|
||||
#### Connect
|
||||
|
||||
To **connect to the WiFi networ**k, run the below command with the WiFi access point name from the above “get-networks” command.
|
||||
|
||||
```
|
||||
station wlan0 connect
|
||||
```
|
||||
|
||||
Enter your WiFi password when prompted.
|
||||
|
||||
![connect to WiFi using iwctl][6]
|
||||
|
||||
If all, goes well you should be connected to the internet.
|
||||
|
||||
### Usage Guides
|
||||
|
||||
* You can check the connection using a simple ping command as follows. The ping replies successful packet transfers for a stable connection.
|
||||
|
||||
```
|
||||
ping -c 3 google.com
|
||||
```
|
||||
|
||||
* You can also check the status of the connection using the below command.
|
||||
|
||||
```
|
||||
station wlan0 show
|
||||
```
|
||||
|
||||
* The iwd keeps the configuration file at `/var/lib/iwd` as a `.psk` file with your access point name.
|
||||
|
||||
* This file contains a hash file that is generated using the password and SSID of your WiFi network.
|
||||
|
||||
* Press `CTRL+D` to leave from the `iwctl` prompt.
|
||||
|
||||
### Wrapping Up
|
||||
|
||||
I hope this guide helps you to connect to the internet via the terminal. This helps when you have no other way to connect to WiFi. For example, if you are installing Arch Linux in a stand-alone system (not a VM), you need to connect to the internet to download packages via a terminal using `pacman`.

在 Arch Linux 和其他发行版中使用终端连接到 WiFi
|
||||
======
|
||||
本快速指南介绍了在 Arch Linux 和其他发行版中使用终端设置和连接 WiFi 所需的步骤。
|
||||
|
||||
本指南非常适合没有 GUI 只有终端且没有其他有线互联网连接可用的情况。这些步骤可帮助你手动检测无线网卡和设备，并通过终端密码验证连接到 WiFi 热点。
|
||||
|
||||
本指南使用 [iwd][1] (Net Wireless Daemon) 通过终端连接到 WiFi。
|
||||
|
||||
### 在 Arch Linux 和其他发行版中使用终端连接到 WiFi
|
||||
|
||||
#### 1. 设置 iwd
|
||||
|
||||
`iwd` 包有三个主要模块：
|
||||
|
||||
**iwctl**：无线客户端，**iwd**：守护进程，**iwmon**：监控工具
|
||||
|
||||
在终端中输入：
|
||||
|
||||
```
|
||||
iwctl
|
||||
```
|
||||
|
||||
![iwctl 提示符][2]
|
||||
|
||||
如果找不到命令，那么需要从[此处][3]下载安装包。
|
||||
|
||||
从任何其他具有 Internet 连接的系统/笔记本电脑获取帮助，以通过安装 USB 下载和安装软件包。
|
||||
|
||||
或者，如果你有一个可连接互联网的 USB 适配器，那么将其插入你的系统。并通过以下命令安装。
|
||||
|
||||
USB 适配器应该在 Arch 和当今大多数 Linux 系统中开箱即用，以连接到互联网。
|
||||
|
||||
**Arch**
|
||||
|
||||
```
|
||||
pacman -S iwd
|
||||
```
|
||||
|
||||
**Debian、Ubuntu 和其他类似发行版**
|
||||
|
||||
```
|
||||
sudo apt-get install iwd
|
||||
```
|
||||
|
||||
**Fedora**
|
||||
|
||||
```
|
||||
sudo dnf install iwd
|
||||
```
|
||||
|
||||
如果你收到 `iwctl` 提示符（如下所示），那么继续下一步。
|
||||
|
||||
#### 2. 配置
|
||||
|
||||
运行以下命令以获取系统的**无线设备名称**。
|
||||
|
||||
```
|
||||
device list
|
||||
```
|
||||
|
||||
![iwctl – 设备列表][4]
|
||||
|
||||
要**获取 WiFi 网络列表**，请运行以下命令。在以下命令和所有其他命令中将 `wlan0` 替换为你的设备名称。
|
||||
|
||||
```
|
||||
station wlan0 get-networks
|
||||
```
|
||||
|
||||
![iwctl – 可用网络][5]
|
||||
|
||||
该命令为你提供具有安全类型和信号强度的可用 WiFi 网络列表。
|
||||
|
||||
#### 连接
|
||||
|
||||
要**连接到 WiFi 网络**，请使用上述 “get-networks” 命令中的 WiFi 接入点名称运行以下命令。
|
||||
|
||||
```
|
||||
station wlan0 connect
|
||||
```
|
||||
|
||||
出现提示符时输入你的 WiFi 密码。
|
||||
|
||||
![使用 iwctl 连接到 WiFi][6]
|
||||
|
||||
如果一切顺利，你现在可以连接到互联网。
|
||||
|
||||
### 使用指南
|
||||
|
||||
* 如下所示，你可以使用简单的 ping 命令检查连接。ping 回复成功的数据包传输表示连接稳定。
|
||||
|
||||
```
|
||||
ping -c 3 google.com
|
||||
```
|
||||
|
||||
* 你还可以使用以下命令检查连接状态。
|
||||
|
||||
```
|
||||
station wlan0 show
|
||||
```
|
||||
|
||||
* iwd 在 `/var/lib/iwd` 中保存 `.psk` 后缀的配置文件，其中带有你的接入点名称。
|
||||
|
||||
* 此文件包含使用你的 WiFi 网络的密码和 SSID 生成的哈希文件。
|
||||
|
||||
* 按 `CTRL+D` 退出 `iwctl` 提示符。
|
||||
|
||||
### 总结
|
||||
|
||||
我希望本指南可以帮助你通过终端连接到互联网。当你没有其他方式连接到 WiFi 时，这会有所帮助。例如，如果你在独立系统（不是 VM）中安装 Arch Linux，那么需要连接到 Internet 以通过终端使用 pacman 下载软件包。
