The Raspberry Pi CM5 is available in models with built-in Wi-Fi. However, it is often said that the onboard antenna provides relatively weak wireless performance. To see whether an external USB Wi-Fi adapter offers a better alternative, we decided to put it to the test.
In addition to the built-in Wi-Fi function, computers can communicate wirelessly via a Wi-Fi adapter (also known as a dongle) that connects via USB.In this issue, we will introduce an example of using a non-wireless model “PL-R4” with a USB-type Wi-Fi adapter attached. The PL-R4 series of industrial-use Raspis includes a model that incorporates the Raspberry Pi Compute Module 4 with Wi-Fi as usual, as well as a model that is not wireless-compatible. Non-wireless models are also in demand. This is because there are some industrial sites where Wi-Fi is not or cannot be used depending on the application. The PL-R4 is wired as standard, and Wi-Fi is an optional…
The current OS allows the Raspberry Pi Wi-Fi to be converted to an access point without using other applications with NetworkManage.
