How to Get Ad Hoc Networking on Debian with the rtl8192cu Driver

This document describes how to modify your system in order to get devices using the RTL8192cu wireless driver to be able to communicate among one another in IEEE 802.11 Ad Hoc networks.

Preliminaries

First, you're going to need static IP addresses. So decide on the range and subnet of the addresses you would like to use. This document will use the range 192.168.2.11-15 for 5 nodes.

Next you'll need to gather your nodes and gather all of their ifconfig information. Simply run ifconfig to get the information. It should look something like the following:

pi@raspberrypi:~ $ ifconfig
