OFFCUP USB WiFi 6E Dongle, 5400Mbps Tri-Band USB 3.0 Adapter

When you want to add wireless connectivity without changing your computer, a USB WiFi adapter offers a straightforward route. The OFFCUP USB dongle combines WiFi 6E tri-band support with a USB 3.0 connection, making it useful for a desktop or laptop that needs WiFi reception or a way to share a wired connection with a mobile device.

Its three bands cover 2.4GHz, 5GHz and 6GHz, with a combined data rate of 5400Mbps. Two 5dBi antennas rotate through 180° to help position the adapter for signal reception, while WPA3 encryption adds a current security feature for wireless connections.

A laptop can also use it as an external WiFi connection, while the stated WiFi send/receive function allows a computer with a network cable connection to provide WiFi to a mobile device.

Need a choice of wireless bands for different everyday connections? This adapter supports 2.4GHz, 5GHz and 6GHz, rather than focusing on a single band. Buyer feedback is mixed: some describe it as working well, while others report reliability concerns, including units that stopped working after two months. Views on its functionality are also divided.

Usage tips

Connect the adapter through a USB 3.0 port and use the supported Windows 10 or Windows 11 system for the stated driver-free setup. Position its antennas by rotating them through their 180° range to suit the computer’s location. The selectable tri-band support gives you three frequency bands to work with, and WPA3 provides encryption for supported wireless connections. For a computer connected by network cable, the adapter’s WiFi send function can also be used to provide a wireless connection to a mobile device.

Is it worth it?

The OFFCUP is a practical fit when you want a USB-based WiFi adapter with more than basic wireless coverage: WiFi 6E tri-band support, a 5400Mbps combined rate, adjustable dual antennas and WPA3 are all part of its feature set. It suits you if you want to add WiFi reception to a compatible desktop or laptop, or use the stated sharing function with a mobile device. Choose it for those specific connection options and its USB 3.0 format.
