Most modern Dell laptops and tablets include a built-in wireless adapter that you can use to connect to Wi-Fi hot spots and surf the Web. With a desktop PC, however, unless you specifically request that Dell install a wireless adapter when you order, it will not include one. In fact, very few desktops include wireless network adapters; instead, these computers connect to networks and routers through a standard RJ-45 Ethernet cable. You can add a USB wireless adapter to a Dell desktop computer easily enough; just plug into a USB port and go in most cases. However, if you want an adapter with better range, and one that does not take up a valuable USB slot or clutter your desk, install an internal PCI wireless card. Writer Bio
