A strong, reliable internet connection is critical for conducting business, and the best Wi-Fi extenders allow you to cover every inch of your office to eliminate dead zones. Many modern Wi-Fi extenders have dual-band connectivity, giving you either a 2.4GHz or 5GHz connection. There are also high-end, tri-band models for even better connection speeds, as well as ones with compact, wall plug designs for offices with limited floor and desk space.

You can even opt for an extender that works with mesh networks: These units act as an access point for Wi-Fi rather than a simple signal repeater. Many extenders also feature Gigabit Ethernet or LAN ports, giving you the option of a hardwired internet connection. So whether you work from home or in a large, open-concept office, here are the best Wi-Fi extenders that'll fit your needs.
