If you’re running a business, then setting up a captive portal can be an important tool for your network. So, in this article, I’ll show you how to create a captive portal with a Raspberry Pi Pico W.<\/p>\n\n\n\n

A captive portal provides a secure way to offer WiFi to guests, customers, or clients. It requires that users log in or authenticate themselves before they can use the internet.<\/p>\n\n\n\n

Think of how it works at an airport or at a coffeeshop chain.<\/p>\n\n\n\n

A captive portal allows you to both control and monitor your network. It also provides an opportunity to extend your brand. You can customize the captive portal with your logo.<\/p>\n\n\n\n

What does a captive portal do?<\/h2>\n\n\n\n

When you log onto a Pico W that’s acting as an access point, you will not get a web page served to you. With a captive portal implemented, once your WiFi connects to your hotspot, a web page will popup.<\/p>\n\n\n\n

Therefore, you can skip the step of connecting to the network, then going to your browser and manually typing in an IP address.<\/p>\n\n\n\n

It’s at this point that I have to credit Kevin McAleer for his video that serves as the basis for this tutorial.<\/a><\/p>\n\n\n\n

Creating a captive portal with a Pico W is a fantastic opportunity. Not only is a captive portal imperative for your business’s network. A Raspberry Pi Pico W<\/a> is just a few Euros at most, so it’s also an extremely cost-effective solution.<\/p>\n\n\n\n

Goals for this tutorial<\/h2>\n\n\n\n

Kevin’s tutorial only shows you how to trigger a captive portal on an Apple device.<\/p>\n\n\n\n

This tutorial will go further by explaining to you how to trigger the pop-up captive portal on Android, Windows and Apple devices.<\/p>\n\n\n\n

We will use Phew by Pimoroni, which is a library for a Pico W web server. It’s a bit like what Express is to NodeJS.<\/p>\n\n\n\n

I’ve tested my code on four devices: <\/p>\n\n\n\n
