“A WiFi repeater built around Raspberry Pi under $10.
Truly WiFi Extender is a WiFi repeater based on Raspberry Pi Zero W. It makes a nice alternative to a commercial WiFi repeater combining low-cost (under 10 USD) and highly customizable software. It can also run some ad-blocking solutions such as pi- hole as well. This project is one of a kind because most of the projects on GitHub demonstrate how to create a wireless AP to share Internet access obtained using Ethernet.
This will run on any version of Raspberry Pi. But make sure to have two wifi adapters. Nowadays, Raspberry Pi comes with onboard WiFi. In case you have an older version, you might have to use two USB WiFi adapters. I will be using a single USB WiFi adapter since I am using Raspberry Pi Zero W.”
