In this blog post, I am going to explain how to change the WiFi card of a mini PC, using the Realtek 8852BE WiFi card, that comes with the Geekom A5, as an example. Many people (myself included) experience WiFi issues when using Linux on an affordable mini PC, such as the Geekom A5. While I absolutely love this device, the chosen WiFi card - the Realtek 8852BE - is not great. It seems to work well on Windows, but on Linux, it can lead to problems: WiFi would often suddenly disconnect and it would not be possible anymore to reconnect to the internet. Only a reboot helps in this situation.
