Raspberry Pi 2/3B/B+/4B Wireless Bridge using Ubuntu Server 18.04 ARM Image and Netplan

The initial goal of this project is to use the raspberry pi in place of my Wireless Range Extender and then going from 3 wireless networks (2.4ghz, 2.4ghz extended, 5ghz) at home to only one (5ghz). This way I'm reducing the exposition to radio waves for the whole familly at home.

Let's go technical

Ok, enough drama for now, let's go technical. 😁

Setup

Parameters

Container: MP4

Backup android app, data included, no root needed, with adb

adb is the Android CLI tool with which you can interact with your android device, from your PC

You must enable developer mode (tap 7 times on the build version in parameters) and install adb on your PC.

	<p>Here are Webber’s points:</p>
	<ul>
	<li>If a method can be static, declare it static. Speed improvement is by a factor of 4.</li>
	<li>echo is faster than print.(<em>* compare with list from phplens by John Lim</em>)</li>
	<li>Use echo’s multiple parameters instead of string concatenation.</li>
	<li>Set the maxvalue for your for-loops before and not in the loop.</li>
	<li>Unset your variables to free memory, especially large arrays.</li>
	<li>Avoid magic like __get, __set, __autoload</li>
