Introduction
Welcome to our guide on how to connect Ubuntu server to WiFi. As we know, internet connectivity is a critical component of any server, and WiFi is a popular choice for many users. In this article, we’ll explore how to connect Ubuntu server to WiFi network and provide you with a detailed explanation of the advantages and disadvantages of using WiFi for your server.
Before we dive into the details, let’s briefly define what Ubuntu server is. Ubuntu server is a Linux-based operating system that is designed to run on servers. It is a popular choice for users who wish to build and run web applications, manage remote servers, or set up a database server.
Now that we’ve established what Ubuntu server is let’s get started on how to connect it to a WiFi network.
Connect Ubuntu Server to WiFi: A Step-by-Step Guide
Step 1: Check Your WiFi Adapter
If you’re planning to connect your Ubuntu server to a WiFi network, you’ll need to ensure that your server has a WiFi adapter. To check if your server has a WiFi adapter, run the following command:
Command |
Output |
|---|---|
lspci | grep Network |
02:00.0 Network controller: Intel Corporation Wireless 7265 (rev 99) |
If the output shows a network controller as in the above table, it means your server has a WiFi adapter.
Step 2: Install the Necessary Drivers
Before we can connect to a WiFi network, we need to ensure that Ubuntu has the necessary drivers installed. To install the drivers, run the following command:
Command |
Output |
|---|---|
sudo apt-get install firmware-iwlwifi |
This command installs the necessary drivers for the Intel WiFi adapter on your Ubuntu server.
Step 3: Update Ubuntu Server
It’s always a good idea to ensure that your server is up-to-date before attempting to connect to a WiFi network. To update Ubuntu server, run the following command:
Command |
Output |
|---|---|
sudo apt-get update && sudo apt-get upgrade |
This command updates and upgrades all the packages on your Ubuntu server.
Step 4: Scan for WiFi Networks
Now that we’ve ensured that the necessary drivers are installed, we can scan for WiFi networks. To scan for WiFi networks, run the following command:
Command |
Output |
|---|---|
sudo iwlist wlp2s0 scan | grep ESSID |
ESSID:”MyWiFiNetwork” |
Replace wlp2s0 with the name of your WiFi adapter and MyWiFiNetwork with the name of the network you want to connect to. This command will list all the available WiFi networks, and you can choose the one you want to connect to.
Step 5: Create a Configuration File
Once you’ve identified the WiFi network you want to connect to, you need to create a configuration file. To create the configuration file, run the following command:
Command |
Output |
|---|---|
sudo nano /etc/netplan/wifi.yaml |
This command will open the nano text editor, where you can create the configuration file.
Step 6: Edit the Configuration File
In the nano text editor, paste the following configuration code:
network:version: 2renderer: networkdwifis:wlp2s0:dhcp4: truedhcp6: falseaccess-points:"MyWiFiNetwork":password: "MyPassword"
Replace wlp2s0 with the name of your WiFi adapter, MyWiFiNetwork with the name of the network you want to connect to, and MyPassword with the password for that network.
Step 7: Apply the Configuration
To apply the configuration, run the following command:
Command |
Output |
|---|---|
sudo netplan apply |
After applying the configuration, your Ubuntu server should be connected to the WiFi network.
