Hardware To use TailsOS safely, an old laptop can be stripped of unnecessary hardware such as WiFi, Bluetooth and WWAN, hard drives/SSDs and other non-essential components for this purpose. WiFi is usually included in laptops, particularly older models, in the form of a small internal mini pcie card. WWAN, where included, is usually nextdoor to WiFi. The cables attached to the cards run to the antennae, usually housed above the screen.
