Now that we’ve covered the advantages of connecting your Ubuntu server to Wi-Fi using the command line, let’s move on to the actual process.

Connecting Your Ubuntu Server to Wi-Fi Using the Command Line

Before we begin, make sure that you have administrative access to your Ubuntu server and that your server has a Wi-Fi adapter installed. If your server does not have a Wi-Fi adapter installed, you can purchase one online or from a local computer store.

Step 1: Install Required Packages

The first step is to install the required packages. Open the terminal and enter the following command:

Command
Description
sudo apt-get update
Updates the package list
sudo apt-get install wireless-tools
Installs the wireless-tools package
sudo apt-get install network-manager
Installs the network-manager package

This will update your package list and install the necessary packages for connecting to Wi-Fi using the command line.

Step 2: Turn on the Wi-Fi Adapter

Next, we need to turn on the Wi-Fi adapter. To do this, enter the following command:

Command
Description
sudo ip link set wlan0 up
Turns on the Wi-Fi adapter

Replace “wlan0” with the appropriate interface name for your Wi-Fi adapter.

Step 3: Scan for Available Wi-Fi Networks

Now that the Wi-Fi adapter is turned on, we can scan for available Wi-Fi networks. To do this, enter the following command:

Command
Description
sudo iwlist wlan0 scan
Scans for available Wi-Fi networks

This will display a list of available Wi-Fi networks in your area.

Step 4: Connect to Your Wi-Fi Network

Once you’ve identified your Wi-Fi network, you can connect to it using the following command:

Command
Description
sudo nmcli device wifi connect “SSID” password “PASSWORD”
Connects to a Wi-Fi network

Replace “SSID” with the name of your Wi-Fi network and “PASSWORD” with your Wi-Fi password. This command will establish a connection to your Wi-Fi network.
