Tri-band Wi-Fi 7 M.2 adapter

The Wavlink WN685BE3M-A is a new M.2 wireless module that adds Wi-Fi 7 and Bluetooth 5.3 connectivity to compatible laptops, mini PCs and embedded systems. It targets users who need tri-band 2.4 GHz, 5 GHz and 6 GHz operation on Intel-based platforms running Windows 10 or 11 64-bit.

M.2 A/E key requirement

The card fits only motherboards with an NGFF M.2 A-key or E-key slot; M-key and B-key slots used for SSDs are not compatible. The package includes a low-profile bracket, external antenna dock and Bluetooth cable for desktop installations.

8774 Mbps aggregate throughput

Maximum link rates reach 574 Mbps on 2.4 GHz, 2400 Mbps on 5 GHz and 5800 Mbps on 6 GHz, supporting 320 MHz channels and 4096-QAM. The 6 GHz band requires Windows 11; AMD-based motherboards are not supported, so buyers needing AMD compatibility must choose a different adapter.

Questions about this item

What does the 8774 Mbps tri-band rating mean once the card is installed in a laptop?

The 8774 Mbps figure is the sum of the maximum PHY rates across all three bands: 574 Mbps on 2.4 GHz, 2400 Mbps on 5 GHz and 5800 Mbps on 6 GHz. Real-world throughput will be lower and depends on router capabilities, channel width and interference.

Which M.2 key and PCIe lane widths does the WN685BE3M-A accept?

The module fits an M.2 A-key or E-key slot and is compatible with PCIe x1, x4, x8 or x16 electrical interfaces. It will not work in M-key or B-key slots used for SSDs.

What physical items are included to mount the adapter and attach antennas?

The package supplies a low-profile bracket, three mounting screws, an external antenna dock and a Bluetooth header cable for internal connection.
