A Tactical Toolkit to Liberate Pay-Per Use Wireless Networks!


Wifi Liberator is an open-source toolkit for a laptop computer that enables its user to “liberate” pay-per-use wireless networks and create a free, open node that anyone can connect to for Internet access. The project is presented as a challenge to existing corporate or “locked” private wireless nodes to encourage the proliferation of free networks and connectivity across the planet. The project was inspired by the ongoing “battle” between providers broadcasting wireless signals in public spaces, in particular: corporate entities, wireless community groups, individual users, and proponents of open networks. Like my Wifi-Hog project, the Wifi-Liberator critically examines the tensions between providers trying to profit from the increasingly minimal costs associated with setting up a public network and casual users who simply want to see the Internet transform into another “public utility” and become as ubiquitous and free as the air we breath. The project targets pay-per-use wireless networks as often found in airports, other public terminals, hotels, global-chain coffee shops, and other public waiting points.

The ultimate goal with the Wifi Liberator project is through Open Source distribution, to eventually reach a high enough usage and penetration rate that all pay-per-use wireless networks will begin to free their access to everyone. Since the monetary amounts associated with providing wireless access is inexpensive as the techology becomes more ubiquitous, the need to “charge” for this access is becoming less important and cost effective. Although we are still charged for basic utilities such as water, electricity, gas, and others, the amounts associated with providing internet access are dropping at an exponential rate. This project aims to make this low cost apparent as well as the increasing tensions of keeping people “out” of these networks.


Despite the advent of free and open wireless networks made available by community groups in parks and other urban centers, there is still a monetary restriction on many networks that exist in community buildings and facilities such as airports, train stations, chain restaurants, and other public areas. Most of these “closed” networks are deployed in “waiting” areas with the promise of “convenience” to allow pedestrians or commuters access to the Internet, however they nevertheless impose a monetary and time-based restriction on who can connect as well as for how long, often with “hourly” or “daily” rates for connectivity. Wifi-Liberator is a reaction against these limits to access by lifting the constrictions associated with paid networks and turning them into “free” networks.

The project finds inspiration from the Open Source movement’s ability to turn once “commercial” software into freely available and distributable entities. This is evident in examples such as Netscape’s eventual movement into the freely available, and open source distribution model with Mozilla and its successor, Firefox. By taking an existing pay-per-use commercial model into the public domain, the potential for creative use and output from these systems increases exponentially. This is the hope of “Wifi-Liberator”, that once the restrictions are lifted on wireless access points that it will stimulate creativity and social action amongst the general public and those in dense urban locations where many networks currently overlap.


The project includes a hardware and software component. The hardware component is an off the shelf, USB wireless card and any laptop with built in wireless hardware. Therefore the “Liberator’s”‘ machine must have 2 wireless interfaces. The software component is a downloadable application called “Liberator” that runs natively on Mac OSX (Windows version coming soon) that needs to be run when connecting to a paid network. The software is based on “Ping Tunnel“, free software written by Daniel Stodle and licensed under the BSD license.

The following equipment list is to get Wifi- Liberator running on an Apple Macbook running OSX 10.3 or later. (Windows version coming soon)

Equipment list

1. Apple Mac OSX Macbook with integrated Airport card
2. Apple Mac OSX machine connected to the Internet with a public IP address.
3. USB wireless network adaptor (I’ve successfully tested using the Addlogix Wireless-G Network Adaptor, but any OSX compatible Wifi/USB stick will work)
4. Wifi Liberator software (one copy of the software for each machine) – see Download Link above

The Wifi-Liberator Software can run in 2 modes – Proxy and Client.

Instructions For Proxy
1. Download and install the WIFI-Liberator software:
OSX 10.3 or later onto a Mac OSX machine with a public IP address (this is a machine that can be accessed over the Internet – aka. a server)
2. Open the software, choose “Proxy Mode”
3. Leave this running. You will also need to run a Proxy on this machine such as Squid.

Instructions For Setting Up The Client
1. Download and install the WIFI-Liberator software: runs on
OSX 10.3 or later:
2. Copy the Liberator software to your Applications folder fromt he Disk Image. Double click to start.
3. Enter the address of the Proxy computer for the Proxy address.
4. Enter ‘www.someURL.com’ for the destination address.
5. Enter ‘1234’ for the listen port.
6. Enter ’80’ for the destination port.
7. Connect the USB stick, Install the drivers, etc…
8. Run the Liberator software and connect to the closed network through the USB stick.
9. Once connected, in OSX go to System Preferences>>Sharing>>Internet>>
10. Choose from the pull down menu:
Share your connection from: “Ethernet Adaptor (en4)”
11. Check “To Computers Using “Airport”
12. Click “Airport Options” and under network name type in: “Wifi Liberator”,
Channel: “Automatic”. (This will be your SSID broadcast name that others will see to connect to.)
13. Make sure “Enable Encryption” is not checked – click “OK”. This will allow you to share your Internet connection to other machines when they connect to the “Wifi-Liberator” node.
14. Close System Preferences.
15. Open a web browser, and enter ‘localhost:1234‘ as the URL. If everything is working, you will have navigated to your URL through the Wifi-Liberator.
16. You’re done! Congratulations and keep sharing your connection until you have to go.

Description of System

1. Closed Node Use: Users who have existing accounts or pay-per-use accounts can access the network. This typically puts a time limit on their use, prompting them for more money or access codes to continue using the network. Those without accounts or enough money to pay for access cannot connect to the node.

2. Wifi Liberator Node Use: The Liberator connects to the network using the software and broadcasts this connection on a second wireless interface from their computer with the SSID “Wifi Liberator”. Users can then connect to the liberated node as they would any other, “free”, hotspot.
