IoT: Howto create a raspberry pi bridge




Introduction

Bridging your network is a method to share your network connection between two computers. Out here we are focusing on a specific use case, i.e., how to share wired internet as an access point using a Raspberry Pi (Model B+) Bridge. Especially in offices, we have wired internet available at each desk. With office Wifi secured with weird authentication schemes, it may just be convenient to have your wifi network to which you can connect your mobile devices. The following figure shows how such a Raspberry Pi wifi bridge may look:

In the above picture, the wired network is connected to the raspberry pi using the ethernet cable. The wifi dongle advertises the hotspot that you can connect to and enjoy the wired internet over wifi. For more information do get in touch.

Raspberry Pi Bridge Configuration

On booting with the above image, your Raspberry Pi will be ready for configuration. All you need to do is connect to the hotspot that Raspberry Pi is publishing, and you will see the following menu:
