A Raspberry Pi WiFi Extender is a cheap and power efficient way of increasing the total range of your WiFi Network. A WiFi extender differs a fair bit from a WiFi access point.
The main difference being that instead of getting its network connection from Ethernet, it instead gets its network connection from a WiFi adapter.
For this reason, to complete this tutorial you will require two WiFi adapters, one of these must be access point capable.
You will face a fair bit of degradation in the speed of your network connection when connecting to the Wi-Fi repeater. The main reason for this is that you must wait for the traffic to go over your initial Wi-Fi connection then be repeated from your Raspberry Pi for devices to connect to.
This tutorial can be combined well with our VPN Access Point tutorial, you can find the tutorial on how to set that up located directly after this tutorial. Basically, it will show how to setup a OpenVPN client and redirect all traffic through that client.
Please note however, this tutorial will require some slight changes, we will explain those changes needed at the end of this tutorial.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
