How to Enable WiFi in Debian 11 Bullseye, Fix Missing wlan0

Are you looking for a way to fix no Wi-Fi problem on Debian? If yes, then you have landed on the right page. In this tutorial, I will share a straightforward method that you can apply to fix the missing Wi-Fi adapter issue on Debian.

If you just did a fresh Debian install on a PC, then you will most likely run into an issue where you can’t access Wi-Fi. Debian will not even show you wlan0 device if you run ip addr show the command.

This happens because the Debian ISO doesn’t include the Wi-Fi firmware by default. Thus, you have to manually install the firmware from a non-free repo in order to use the Wi-Fi facility.

Depending on the network card manufacturer of your computer, you have to install the correct firmware. If you are using a laptop of popular brands such as Lenovo, Acer, Samsung or Asus, which usually use Atheros network card, it could be a little daunting to find the right version of the firmware to install.

I ran into this issue a little while ago and couldn’t find a quick solution so I thought maybe share the fix, so others do not have to face what I went through. Let’s cut to the chase and see the steps involved:

1. First, identify the manufacturer of your Wi-Fi network card.
2. Install the firmware matching your network card manufacturer.

See how to complete these two steps below.

Step 1: Identifying Wi-Fi Network Card Manufacturer on Debian

There is a CLI utility called lshw which can help you identify all the hardware installed on your computer, including the network card. A very good chance is that it will be pre-installed. If not, then you will have to install it by connecting your PC to an Ethernet connection. You can use your Android phone as an Ethernet device via USB tethering.

Install lshw like this:

sudo apt install lshw

It is now time to use lshw to find out the network card vendor. Run the command below and wait for it to generate the HTML report.

lshw -html > lsh.html

Open the generated HTML report(lsh.html) in the browser and search for network or network controller. You will find the result something like this:

From this screenshot, it is now evident that the vendor of my network card is Atheros! But it can also be Intel. It all depends on the PC/laptop manufacturer. Never mind, it doesn’t matter because, firmware for both these cards available for Debian. See in next section, how to install it.

Step 2: Installing firmware matching your network card manufacturer on Debian.

In the last step, you will know what network card is installed on your system. So, based on what card it is, you need to install the correct firmware.

For Atheros Card:

On my Lenovo Ideapad 300-15ISK, it was Atheros card, as evident from the snapshots above.

So, to install the firmware for Atheros, you issue the following command.

sudo apt install firmware-atheros

After the firmware installs, you can try restarting your computer. You will now see that it will detect the available Wi-Fi networks nearby.

Alternatively, you can download the DEB file for the same firmware on some other device, transfer to the Debian PC, and manually install it.

After getting the DEB file, you open the terminal in the Downloads directory and issue this command.

sudo dpkg -i firmware-atheros*

After it completes, successfully, you will have both; wla0 will start showing along with the Wi-Fi network.

For Intel Card:

To install the firmware for Intel network controller, you issue the following command.

sudo apt install firmware-iwlwifi

After it installs successfully, restart your computer. You will now see that it will detect nearby Wi-Fi networks.

Alternatively, you also download the DEB file for the same firmware on some other device, transfer to the Debian PC, and install it manually.

Find and get Intel Wireless firmware here: firmware-iwlwifi (20210315-3) [non-free]

After getting the DEB file, you open the terminal in the Downloads directory and issue this command.

sudo dpkg -i firmware-iwlwifi*

After it completes, successfully, you will have both; wlan0 will start showing along with the Wi-Fi network.

These are the only two steps you have to perform. If you follow them correctly, I am sure you will get Wi-Fi access on Debian in easy way. Although, I hope that they make this process a bit smoother by restoring these back to the installation ISO.

How to Install TP-Link USB WiFi Adapter on Debian 10

So, a few days back I shifted to Debian 10 from Ubuntu and unfortunately, Debian decided to not recognize my WiFi Dongle/USB WiFi Adapter. It took a lot of effort at trying to configure the device driver but it boiled down to the fact that my Debian lacked the appropriate driver for my TP-Link WiFi device. After installing the driver and finally getting successful in getting my WiFi work on Debian, I jotted down the steps for whoever faces the same situation as me.

We have run the commands and procedures mentioned in this article on a Debian 10 Buster system.

Please follow these steps, one by one, in order to install the appropriate TP-Link WiFi driver on your Debian:

Step 1: Open the Terminal

Open the Terminal application by pressing the Super(Windows) key and searching for it through the Application Launcher as follows:

Step 2: Update the Repository Index

Login as root by entering su and then the password for root. You are now authorized to add/remove and configure software on Debian. Now, enter the following command in order to update the local repository index with that of the Internet. This helps you in installing the latest version of a software available online.

Step 3: Install the Prerequisites

The process of installing the WiFi Adapter’s driver includes downloading it from the Internet and then installing it on your system. This requires installing Linux Headers, Build Essential and the git packages on your Debian. Run the following commands as root, one by one, in your Terminal:

# apt-get install linux-headers-$(uname -r)

# apt-get install build-essential

Step 4: Download the driver from git hub

Search for the relevant driver on GitHub. I found the driver for my TP-Link device on:

https://github.com/lwfinger/rtl8188eu

Download the driver by cloning it on your system. This is how I cloned my driver:

$ git clone https://github.com/lwfinger/rtl8188eu

The cloned folder will now exist in your home drive. Simply switch to this folder through the cd command. And then install the driver through the make command. For example, I followed the following steps:

Finally, configure the driver through the following command and restart your system:

You can also blacklist an internal driver if it already existed on your system by adding it to the file: /etc/modprobe.d/blacklist

As you log in again, you will be able to see the WiFi adapter card listed in the WiFi tab of the Settings utility.

You are now ready to connect to the Internet through this adapter.

Setup Wi-Fi Adapter and Configure Wireless Interface

I’ll show an example of how to configure a connection to a wireless network from the console of the Debian system by using Wi-Fi Adapter “ASUS USB-N10 Nano” ( ID: 0b05:17ba , Driver: rtl8192cu ).

Installing driver/firmware for Wi-Fi Adapter

Wi-Fi Adapter “ASUS USB-N10 Nano” is uses the driver “rtl8192cu”, wich can be found in the firmware-realtek package.

1. Add a non-free component to /etc/apt/sources.list , for example:

# Debian 7 "Wheezy" deb http://http.debian.net/debian/ wheezy main contrib non-free

2. Update the list of available packages and install the firmware-realtek package:

sudo apt-get update sudo apt-get install firmware-realtek 

3. Connect the device to your system.

Now the adapter is setuped.

Scaning Networks

Scan for available networks and get network details:

Configure Wireless Interface

1. We are going to connect to the wireless network with WPA-PSK/WPA2-PSK authentication method, so before continuing, we need to install the wpasupplicant package:

sudo apt-get install wpasupplicant 

2. Restrict the permissions of /etc/network/interfaces , to prevent pre-shared key (PSK) disclosure:

sudo chmod 0600 /etc/network/interfaces 

3. Open /etc/network/interfaces in a text editor:

sudo nano /etc/network/interfaces 

Then append the define appropriate stanzas for your wireless interface, along with the SSID and PSK. For example:

# WiFi auto wlan0 iface wlan0 inet dhcp wpa-ssid NNNN wpa-psk NNNN

The auto stanza will bring your interface up at system startup.

4. We can now bring our interface up and down with the usual ifup and ifdown commands:

This will start wpa_supplicant as a background process.

If you added auto wlan0 as in the example above, the interface should be brought up automatically during boot up.
