Separating functionality on your home network can be a good thing. If you have a spare S Raspberry Pi, give this a try. The RaspAP project uses some fairly standard Linux tools, along with a web interface, to allow you to turn your Pi into a Wi-Fi SSID. This means you can turn your router’s Wi-Fi functionality off and use RaspAP instead.
Note: the range provided by the antenna built in to the Pi may not be as good as your standard router. First install Ubuntu on a memory card using the Raspberry Pi Imager tool. Go to www.raspberrypi.com/software/, and download and install the software. Once opened, click Device and select your device. From the Operating System section, find Raspberry Pi OS Lite, then in the Storage section, select the memory card you want to write the image to. Select Next and use the options to select a username and password as well as enable SSH. You don’t need to configure the Wi-Fi as this will be configured using RaspAP and connected to your network via Ethernet cable.
Once the card has been written, eject it and insert it into the Pi. Connect the Pi to your wired network and plug in the power. Back on the device used to write the memory card, in the terminal connect to the Pi via SSH:
$ ssh USERNAME@IP_ADDRESS
Replace USERNAME with what was entered in the imaging tool, and IP_ADDRESS with what has been assigned via DHCP. To get this info, you may need to log in to your router, to see what has been assigned. Use the install script and package manager to install the necessary packages. Note: RaspAP doesn’t support Ubuntu 24.04/24.10, so install Raspbian OS to your card (see https://raspap.com/#quick). Test your new access point by connecting a device to it and ensuring you can access other devices on the network and access to the internet is working as expected.
