Full details

The TP-Link TL-WN722N is a wireless USB adapter designed for users needing to add or upgrade Wi-Fi connectivity on their desktop or notebook computers. It offers a key benefit of improved wireless signal range and speed compared to older standards, thanks to its 802.11n technology and a high-gain external antenna. A potential caveat is that it operates on a single 2.4 GHz band, which may be more susceptible to interference in crowded Wi-Fi environments.
