Raspberry Pi Disable Wi-Fi: 7 Ways You Can Turn Off Raspberry Pi Wi-Fi
1. Disable Wi-Fi using the Raspberry Pi Configuration Tool
One of the easiest ways to disable Wi-Fi on your Raspberry Pi is by using the built-in Raspberry Pi Configuration tool. Here’s how you can do it:
- Open the Raspberry Pi Configuration tool by clicking on the Raspberry icon in the top-left corner of the screen and selecting “Preferences” > “Raspberry Pi Configuration”.
- In the Raspberry Pi Configuration window, navigate to the “Interfaces” tab.
- Locate the “Wi-Fi” option and click on the radio button next to “Disabled”.
- Click on the “OK” button to save the changes.
After following these steps, the Wi-Fi on your Raspberry Pi will be disabled, and the wireless interface will no longer be available.
2. Disable Wi-Fi using the command line
If you prefer using the command line, you can disable Wi-Fi on your Raspberry Pi by modifying the network configuration file. Here’s how you can do it:
- Open a terminal window on your Raspberry Pi.
- Open the network configuration file using a text editor like nano by running the following command:
sudo nano /etc/network/interfaces
- Look for the lines related to the wireless interface (usually named
wlan0
). They should look something like this:
auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf - Comment out or remove these lines by adding a
#
symbol at the beginning of each line:
#auto wlan0
#allow-hotplug wlan0
#iface wlan0 inet dhcp
# wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf - Save the changes by pressing
Ctrl + X
, followed byY
and thenEnter
. - Reboot your Raspberry Pi for the changes to take effect:
sudo reboot
After the reboot, the Wi-Fi on your Raspberry Pi will be disabled.
3. Disable Wi-Fi using the rfkill
command
The rfkill
command is a utility that allows you to control the state of wireless devices on your Raspberry Pi. You can use it to disable Wi-Fi with a single command. Here’s how:
- Open a terminal window on your Raspberry Pi.
- Run the following command to disable Wi-Fi:
sudo rfkill block wifi
This command will immediately disable the Wi-Fi on your Raspberry Pi. To re-enable Wi-Fi, you can use the following command:
sudo rfkill unblock wifi
4. Disable Wi-Fi by modifying the wpa_supplicant
configuration
The wpa_supplicant
is a program responsible for managing Wi-Fi connections on your Raspberry Pi. By modifying its configuration file, you can disable Wi-Fi. Here’s how:
- Open a terminal window on your Raspberry Pi.
- Open the
wpa_supplicant
configuration file using a text editor like nano:
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
- Add the following line at the beginning of the file:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
ap_scan=0 - Save the changes by pressing
Ctrl + X
, followed byY
and thenEnter
. - Reboot your Raspberry Pi for the changes to take effect:
sudo reboot
After the reboot, the Wi-Fi on your Raspberry Pi will be disabled.
5. Disable Wi-Fi by blacklisting the wireless module
Another way to disable Wi-Fi on your Raspberry Pi is by blacklisting the wireless module. This prevents the module from loading during the boot process. Here’s how you can do it:
- Open a terminal window on your Raspberry Pi.
- Create a new file named
wireless-blacklist.conf
in the/etc/modprobe.d/
directory:
sudo nano /etc/modprobe.d/wireless-blacklist.conf
- Add the following line to the file:
blacklist brcmfmac
Note:brcmfmac
is the name of the wireless module used by most Raspberry Pi models. If you have a different wireless module, replacebrcmfmac
with the appropriate module name. - Save the changes by pressing
Ctrl + X
, followed byY
and thenEnter
. - Reboot your Raspberry Pi for the changes to take effect:
sudo reboot
After the reboot, the wireless module will be blacklisted, effectively disabling Wi-Fi on your Raspberry Pi.
6. Disable Wi-Fi using the systemctl
command
The systemctl
command is used to manage system services on your Raspberry Pi. You can use it to disable the Wi-Fi service. Here’s how:
- Open a terminal window on your Raspberry Pi.
- Run the following command to disable the Wi-Fi service:
sudo systemctl disable wpa_supplicant.service
- Reboot your Raspberry Pi for the changes to take effect:
sudo reboot
After the reboot, the Wi-Fi service will be disabled, and Wi-Fi will no longer be available on your Raspberry Pi.
7. Physically disable Wi-Fi by removing the wireless module
If you want to permanently disable Wi-Fi on your Raspberry Pi and don’t plan to use it in the future, you can physically remove the wireless module from the board. Here’s how:
- Shut down your Raspberry Pi and unplug the power cable.
- Locate the wireless module on your Raspberry Pi board. It is typically a small rectangular component with a metal shield.
- Carefully remove the wireless module from the board. It may be connected via a connector or soldered directly to the board.
- If the wireless module is connected via a connector, gently lift it up to detach it from the board.
- If the wireless module is soldered to the board, you may need to use a soldering iron to desolder it. Exercise caution and seek assistance if you’re not comfortable with soldering.
After removing the wireless module, your Raspberry Pi will no longer have Wi-Fi capability, effectively disabling it permanently.
