How to turn a Raspberry Pi into a Wi-Fi access point

A Raspberry Pi is a versatile piece of hardware and can be used in a range of DIY projects, from DIY Amazon Echos to Mars rovers.

However, the Raspberry Pi can also be used for more simple projects, including assuming the role of a network device.

Therefore, if you aren’t currently using your Raspberry Pi as a smart device, why not turn it into a wireless access point for your home?

This project is easy to complete and requires only basic hardware and software knowledge.

We have outlined how to set up a Raspberry Pi as an access point below.


Technically, a number of Raspberry Pi devices could be used to set up an access point.

However, we will use the Raspberry Pi 3 Model B in our example, due to its built-in wireless features which remove the need for additional dongles.

You will need the following to set up the access point:

  • Raspberry Pi 3 Model B
  • Power supply
  • Monitor
  • MicroSD card with NOOBs installed
  • Mouse and keyboard
  • Ethernet or Wi-Fi Internet connection

Use a power supply which is approved for your Raspberry Pi model, as others may not provide sufficient power to the device for it to boot safely.

Additionally, the monitor, mouse, and keyboard are not needed if you have already set up your Raspberry Pi to be accessible from another device via SSH.


First, boot up the Rapsberry Pi with an SD card inserted and install the latest version of the Raspbian operating system.

Ensure that it is updated to the latest version by running the following commands in the terminal:

sudo apt-get update
sudo apt-get upgrade

All the software required to set up the Pi as an access point can then be installed by running the following command:

sudo apt-get install dnsmasq hostapd

Then turn the software off temporarily and configure a static IP by running the following commands:

sudo systemctl stop dnsmasq
sudo systemctl stop hostapd
sudo nano /etc/dhcpcd.conf

This should open a file editor. Edit the end of the file to reflecting the following:

interface wlan0
static ip_address=
nohook wpa_supplicant

Now run the following commands in order to restart the dhcpcd daemon and configure the DHCP server:

sudo service dhcpcd restart
sudo mv /etc/dnsmasq.conf /etc/dnsmasq.conf.orig
sudo nano /etc/dnsmasq.conf

Add the information below to the file that was just opened and save it before exiting.

interface=wlan0 # Use the require wireless interface – usually wlan0

This will provide IP addresses between and to all connected devices.

Open the hostapd file by typing the following command into the terminal:

sudo nano /etc/hostapd/hostapd.conf

Add the information below to the file before saving and exiting.


Then run the following command:

sudo nano /etc/default/hostapd

Then replace the existing “#DAEMONCONF” line with the entry below:


The access point is now set up and can be started by running the following commands and then rebooting:

sudo systemctl start hostapd
sudo systemctl start dnsmasq


Now that the Pi is acting as an access point to the network, we need it to share its Internet connection to turn it into a Wi-Fi access point.

This can be done by bridging the Pi’s wireless and Ethernet connections.

First, run the following commands in order:

sudo apt-get install hostapd bridge-utils
sudo systemctl stop hostapd
sudo nano /etc/dhcpcd.conf

Add “denyinterfaces wlan0” and “denyinterfaces eth0” to the end of this file and save it.

Then run the commands below to add a new bridge:

sudo brctl addbr br0
sudo brctl addif br0 eth0
sudo nano /etc/network/interfaces

Add the following information to the end of the file to set up the bridge:

# Bridge setup
auto br0
iface br0 inet manual
bridge_ports eth0 wlan0

You can then add a “bridge=br0” line to the “hostapd.conf” file you set up earlier to enable the bridge and share your Internet connection across your Raspberry Pi.

This guide provides a brief overview of the commands required to set up a Raspberry Pi 3 Model B as an access point and does not delve into details regarding routing and network configuration.
