The TP-Link TL-WN722N is a wireless USB adapter designed to bring Wi-Fi connectivity to computers that lack a built-in wireless card. It supports speeds up to 150Mbps using the 802.11n standard, while remaining compatible with older 802.11g and 802.11b networks on the 2.4GHz frequency. To ensure a stable connection, it features a detachable 4dBi omnidirectional antenna, which you can replace or adjust to better capture signals in your home or office. This compact white device connects via a USB 2.0 interface and includes a dedicated WPS button for quick, secure pairing with your router. Its small dimensions of 93.5 x 26 x 11 mm make it unobtrusive when plugged into a desktop or laptop. For those who need more flexibility in positioning the adapter to avoid interference, the package comes with a USB extension cable. It is a versatile choice for users running Windows 11, Mac OS 10.15, or Linux. Security is handled through WEP and WPA-PSK/WPA2-PSK encryption, ensuring your data remains protected. Along with the adapter, you receive a resource CD and a quick installation guide to help you get online quickly.
