Picture of Raspberry Pi Enterprise Network WiFi Bridge

By: Riley Barrett and Dylan Halland

The goal of this project is to allow an IoT device, such as a Weemo Smart Plug, Amazon Echo, Gaming Console, or any other Wi-Fi enabled device to connect to a WPA_EAP Enterprise Network by using a Raspberry Pi Zero W as a packet forwarding device. Extra configuration steps are required for devices connecting to an enterprise network, and many devices are not compatible at all. By using a Wi-Fi Bridge, any device can easily obtain internet access by connecting to the Pi.

The system can be implemented on either one wireless card or two separate cards depending on the requirements of the user. For systems requiring higher signal strength and faster upload/download speeds, it is best to use a dedicated wireless card to host the access point. However, for systems where the signal strength and bandwidth are less important, or where a more cost effective solution is desired, a single card can be shared by the access point and network connection.

Step 1: Setting Up the Raspberry Pi

Begin by connecting your Pi to a keyboard and monitor (may require an HDMI adapter).

Then, you can begin by typing the command:

sudo su

This will ensure you have the necessary privileges to modify files on the pi.

Now you will want to install dnsmasq and hostapd using the command:

apt-get install dnsmasq hostapd

You can now begin to setup the WiFi bridge.

NOTE - The following tutorial will contain information for those using the single on-board wireless card for both the access point and for connecting to the network. It is also possible to configure the system to run on two separate cards. To do this, simply look for the commented out "wlan1" lines in the provided files, and substitute them for the neighboring "ap0" lines.
