Tri-band Wi-Fi 7 desktop adapter

The Wavlink WN685BE3-B installs in a PCIe slot and uses the Intel BE200 chipset to deliver 574 Mbps on 2.4 GHz, 2400 Mbps on 5 GHz and 5800 Mbps on 6 GHz. It also adds Bluetooth 5.4 through an internal 9-pin header cable. Windows 10 or 11 64-bit is required, with Windows 11 needed for 6 GHz operation.

Desktop builders with compatible Intel-chipset

Suits users who want tri-band Wi-Fi 7 and Bluetooth 5.4 on a Windows desktop. Not for laptops or small-form-factor systems lacking a full-height or low-profile PCIe slot. Not for motherboards built around AMD chipsets, as the supplier states compatibility is not supported on those platforms. Buyers who cannot run a Bluetooth header cable to the motherboard will not get Bluetooth functionality.

6 GHz band requires Windows 11

The adapter’s 6 GHz radios and 5800 Mbps top rate are only usable when the operating system is Windows 11 64-bit; Windows 10 limits operation to 2.4 GHz and 5 GHz bands. This single software constraint decides whether the full tri-band capability can be realised.
