A Raspberry Pi wireless access point is a great way to extend the length of your Wi-Fi coverage and provide additional access into your network.

Raspberry Pi WiFi Access Point VPN v3

In this tutorial, we will show you how to set up a wireless access point, and how to configure the multiple packages that allow users to connect to your access point as if it was a router itself.

You will need to keep in mind that a Wi-Fi dongle most likely won’t be able to handle as much traffic as a regular router. Meaning you should avoid allowing too many connections to the device to stop it from becoming too overburdened and slow.

While you can use any Wifi dongle that supports being enabled as an access point our tutorial will directly focus on how to set this up for the Raspberry Pi 3’s Wi-Fi Module. If you are using an earlier model of the Raspberry Pi you can purchase a Wi-Fi adapter that supports being utilized as an access point from numerous websites, make sure you research before buying to make sure it works on the Raspberry Pi.

This tutorial can be combined well with our VPN Access Point tutorial. The VPN access point tutorial will show how to set up an OpenVPN client and redirect all traffic through that client.

Equipment List

Below are all the bits and pieces that I used for this Raspberry Pi Wireless Access Point tutorial, there is nothing super special that you will need to be able to complete this.


Raspberry Pi 2 or 3

Micro SD Card or a SD card if you’re using an old version of the Pi.

Power Supply

Wifi dongle (The Pi 3 has WiFi inbuilt)

Ethernet Connection


Raspberry Pi Case

Setting up the Wireless Access Point

As with most tutorials I do, this one just uses a clean version of Raspbian that has been updated to the latest packages.

To set up the Raspberry Pi wireless access point we will be making the use of two packages. These two packages are hostapd and dnsmasq. hostapd is the package that allows us to utilize a Wi-Fi device as an access point, in our case, we will be utilizing this to turn the Raspberry Pi 3’s Wi-Fi into our access point.

dnsmasq acts as both a DHCP and DNS server so that we can assign IP addresses and process DNS requests through our Raspberry Pi itself.

Luckily dnsmasq is easy to set up and configure. It also has the advantage that it is somewhat lightweight in comparison to isc-dhcp-server and bind9 packages.

Remember for this you will need to be utilizing an ethernet network connection and not your Wi-Fi connection.

1. Before we get started installing and setting up our packages, we will first run an update on the Raspberry Pi by running the following two commands.

sudo apt-get update
sudo apt-get upgrade

2. With that done we can now install our two packages, run the following command to install hostapd and dnsmasq.

sudo apt-get install hostapd dnsmasq

3. Now that we have the packages installed we don’t want them running yet as we haven’t configured them correctly.

Stop the packages from running by utilizing the following two commands in the terminal. These commands will tell the system manager to stop the dnsmasq and hostapd services.

sudo systemctl stop hostapd
sudo systemctl stop dnsmasq

4. With hostapd and dnsmasq now stopped we will want to modify our dhcpd configuration so that we can take control of the wlan0 interface.

With this file, we will be setting ourselves a static IP Address as well as telling it not to make use of the wpa_supplicant file so we can configure it purely as an access point to our device.

Run the following command on your Raspberry Pi to begin modifying the dhcpcd.conf file.

sudo nano /etc/dhcpcd.conf

5. Within this file we need to add the following line to the bottom, this will set up our wlan0 interface to the way we want it for our tutorial.

If you have upgraded to Raspbian Stretch then wlan0 may need to be changed, if you are using the Raspberry Pi 3 or the Pi Zero W’s inbuilt wifi you can continue using wlan0. Use the ifconfig command to see what the new names are, they’re likely quite long. You will need to update any reference to the new values throughout this tutorial.

interface wlan0
    static ip_address=
    nohook wpa_supplicant

Now we can save and quit out of the file by pressing Ctrl +X then pressing Y and then Enter.

6. Now we need to restart our dhcpd service so it will load in all our configuration changes. To do this run the following command to reload the dhcpd service.

sudo systemctl restart dhcpcd

7. Next, we need to adjust our hostapd configuration, to do this we need to begin editing the config file with the following command.

sudo nano /etc/hostapd/hostapd.conf

8. In this file we need to write out the following lines, these basically set up how we want to interact with the wlan device. The only real lines you should worry about in this file is the ssid= line and the wpa_passphrase= line.

As a general rule of thumb, you should try and make your WPA Passphrase longer than 6 characters to help keep your connection secure.

NOTE: If you are doing this tutorial with a different Wi-Fi device then the inbuilt Pi 3 one, you may have to also change the driver= line to the best driver for your device, Google will be your friend for working out what the best driver to use is.




# This is the name of the network
# The network passphrase

Remember to change wpa_passphrase to your own password, make sure you set it to something secure so random people can’t just connect into your Wi-Fi access point.

Now we can save and quit out of the file by pressing Ctrl +X then pressing Y and then Enter.

9. With that done we should now have our hostapd configuration, but before it can be used we need to edit two files. These files are what hostapd will read to find our new configuration file.

To begin editing the first of these two files run the following command.

sudo nano /etc/default/hostapd

10. In this file, we need to find the following line and replace it.



Replace with:


Now we can save and quit out of the file by pressing Ctrl +X then pressing Y and then Enter.

11. Now we need to edit the second configuration file, this file is located within the init.d folder. We can edit the file with the following command:

sudo nano /etc/init.d/hostapd

12. In this file, we need to find the following line and replace it.



Replace with:


Now we can save and quit out of the file by pressing Ctrl +X then pressing Y and then Enter.

13. With hostapd now set up, we need to move onto setting up dnsmasq. Before we begin editing its configuration file we will rename the current one as we don’t need any of its current configurations.

We can do this with the following command on our Raspberry Pi.

sudo mv /etc/dnsmasq.conf /etc/dnsmasq.conf.orig

14. Now that the original configuration file has been renamed we can begin by creating our own new configuration file. We will create and edit the new file with the following command.

sudo nano /etc/dnsmasq.conf

15. To this file add the following lines.

These lines tell the dnsmasq service how to handle all the connections coming through and what interface it should be handling them for.

interface=wlan0       # Use interface wlan0  
server=       # Use Cloudflare DNS  
dhcp-range=,,12h # IP range and lease time

Now we can save and quit out of the file by pressing Ctrl + X then pressing Y and then Enter.

16. Next, we need to configure your Raspberry Pi so that it will forward all traffic from our wlan0 connection over to our ethernet connection.

First, we must enable it through the sysctl.confconfiguration file, so let’s begin editing it with the following command.

sudo nano /etc/sysctl.conf

17. Within this file, you need to find the following line and remove the # from the beginning of it.



Replace with:


18. Now since we are impatient and don’t want to wait for it to enable on next boot we can run the following command to activate it immediately.

sudo sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"

19. With IPv4 Forwarding now enabled we can configure a NAT between our wlan0 interface and our eth0 interface. Basically, this will forward all traffic from our access point over to our ethernet connection.

Run the following commands to add our new rules to the iptable.

sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

20. The iptable is flushed on every boot of the Raspberry Pi so we will need to save our new rules somewhere so they are loaded back in on every boot.

To save our new set of rules run the following command.

sudo sh -c "iptables-save > /etc/iptables.ipv4.nat"

21. Now with our new rules safely saved somewhere we need to make this file be loaded back in on every reboot. The most simple way to handle this is to modify the rc.local file.

Run the following command to begin editing the file.

sudo nano /etc/rc.local

22. Now we are in this file, we need to add the line below. Make sure this line appears above exit 0. This line basically reads the settings out of our iptables.ipv4.nat file and loads them into the iptables.


exit 0

Add above “exit 0”:

iptables-restore < /etc/iptables.ipv4.nat

Now we can save and quit out of the file by pressing Ctrl +X then pressing Y and then Enter.

23. Finally, all we need to do is start the two services and enable them in systemctl. Run the following two commands.

sudo systemctl unmask hostapd
sudo systemctl enable hostapd
sudo systemctl start hostapd
sudo service dnsmasq start

24. Now you should finally have a fully operational Raspberry Pi wireless access point, you can ensure this is working by using any of your wireless devices and connecting to your new access point using the SSID and WPA Passphrase that was set earlier on in the tutorial.

To ensure everything will run smoothly it’s best to try rebooting now. This will ensure that everything will successfully re-enable when the Raspberry Pi is started back up. Run the following command to reboot the Raspberry Pi.

sudo reboot

This is yet another great project for the Raspberry Pi that can be extended to make it an extremely useful utility. As I mentioned above you can make this a WiFi access node where you can route all the internet traffic through a VPN.
