It is dependent on the laptop and wifi adapter you are using. Some laptops, particularly those running Windows 11 or 10, include a built-in wifi adaptor. Some older operating systems, particularly Windows 7 and XP, require an additional tuner or card to connect wirelessly. Furthermore, some latest routers support direct connections between devices without the use of additional hardware. If you're unsure how to perform this, contact your ISP or router manufacturer for assistance.
