If you have a Raspberry Pi with Sixfab shield/HAT connected to a Cellular Network, you can easily convert it into a Wi-Fi Hotspot. By the end of this tutorial, you will have a WiFi Raspberry Pi hotspot.

Before you get started, it's important to set up your hardware correctly and have a cellular internet connection. To set up the hardware please follow:

• Raspberry Pi 3G/4G & LTE Base HAT - Getting Started

Installation

Make a backup of the Wi-Fi connection configuration. To do this, go to the terminal of the raspberry pi and run the following commands:

sudo cp /etc/wpa_supplicant/wpa_supplicant.conf /etc/wpa_supplicant/wpa_supplicant.conf.sav

sudo cp /dev/null /etc/wpa_supplicant/wpa_supplicant.conf

Add following lines in the file /etc/wpa_supplicant/wpa_supplicant.conf.

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

After that, all we need to do is install RaspAP.

RasAP is a software that allows us to manage the access point and hotspot on the web interface.

Prerequisites

Start with a clean install of the latest release of Raspberry Pi OS (32-bit) Lite. The Raspberry Pi OS desktop and 64-bit beta distros are unsupported.

1. Update Raspbian, including the kernel and firmware, followed by a reboot:

sudo apt-get update
sudo apt-get full-upgrade
sudo reboot

2. Set the "WLAN country" option in raspi-config's Localisation Options: sudo raspi-config

With the prerequisites done, you can proceed with the Quick installer steps below.

Quick installer

Install RaspAP from your RaspberryPi’s shell prompt:

curl -sL https://install.raspap.com | bash

After the reboot at the end of the installation the wireless network will be configured as an access point as follows:

From the configure hotspot tab, set and save as follows.
