How to Set Up WiFi in Ubuntu Server

Setting up WiFi in Ubuntu Server is a simple process that can be done in just a few steps. Here’s how:

Step 1: Check Your Hardware

Before you start, ensure that your server has a WiFi adapter installed. If you are unsure whether your server has a WiFi adapter, you can check the output of the following command:

lspci -nnk | grep -i net -A2

This command should display information about the network adapters in your server. Look for a line that says “Wireless Network Adapter” to determine if your server has a WiFi adapter installed.

Step 2: Install the Required Packages

Next, you need to install the packages required to use WiFi on your Ubuntu Server. You can install these packages by running the following command:

sudo apt-get install wireless-tools wpasupplicant

Step 3: Configure the Network

Once the required packages are installed, you can start configuring the network. To do this, you will need to edit the network interfaces file. You can do this by running the following command:

sudo nano /etc/network/interfaces

Add the following lines to the end of the file:

auto wlan0

iface wlan0 inet dhcp

wpa-ssid YOUR_NETWORK_NAME

wpa-psk YOUR_NETWORK_PASSWORD

Replace “YOUR_NETWORK_NAME” and “YOUR_NETWORK_PASSWORD” with the name and password of your WiFi network. Save and exit the file.

Step 4: Restart the Networking Service

Once you have configured the network, you will need to restart the networking service for the changes to take effect. You can do this by running the following command:

sudo service networking restart

Your server should now be connected to your WiFi network. You can verify this by running the following command:

ifconfig wlan0

This command should display information about your network, including your IP address and network status.
