A USB wireless adapter is a small device that plugs into a computer’s USB port to provide Wi‑Fi connectivity.
It allows desktops or laptops without built‑in wireless support to connect to a Wi‑Fi network. Some models also offer faster speeds and better signal strength than older internal Wi‑Fi cards.
Common uses: Adding Wi‑Fi to a desktop, upgrading wireless speed, replacing a damaged Wi‑Fi card
