In continuation of the previous article, Raspberry Pi with OpenWrt as Wireless Router, we can explore more of OpenWrt wireless configuration through the command line with its configuration utility called UCI (Unified Configuration Interface) to configure the OpenWrt access point. We can do a basic smoke test of the new router.

Raspberry Pi is a single-board computer (with an ARM Cortex-A72 64-bit quad-core) made by Raspberry Pi Foundation for educative exploration. It is commonly called R-Pi/rpi for short and used by hobbyists as a mini PC and for developing embedded and IoT applications.

To build a wireless router, we need a wireless router stack, where OpenWrt is the key contender. OpenWrt is an open-source Linux-based operating system meant for networking equipment (routers, access points). And well and good that OpenWrt supports Raspberry Pi as one of the targets.

In this article we will try to run OpenWrt on RPi and transform it into a WiFi router.
