Model AX5400

  • Tri-band Wi-Fi 6E reaches 2400 Mbps on 5 GHz and 6 GHz
  • Bluetooth 5.3 gives 2× speed and 4× range over BT 4.2
  • Intel AX210 chipset adds 6 GHz band for less congestion
  • MU-MIMO and OFDMA cut lag by up to 75 %
  • Two 5 dBi antennas plus heat sink keep signal strong and stable

Tri-band Wi-Fi 6E desktop adapter

The Wavlink WN675X3-C adds Wi-Fi 6E and Bluetooth 5.3 to a desktop PC through a PCIe x1, x4, x8 or x16 slot. It uses the Intel AX210 chipset to deliver 574 Mbps on 2.4 GHz, 2400 Mbps on 5 GHz and 2400 Mbps on 6 GHz. The card supports 802.11ax with OFDMA, MU-MIMO and WPA3 security. A low-profile bracket is included for small-form-factor cases.

Antennas bracket and Bluetooth cable

Two external 5 dBi antennas screw onto the rear bracket to extend coverage. A separate Bluetooth header cable connects the adapter to the motherboard for Bluetooth 5.3 functionality. A driver download card and manual complete the bundle so the card works on Windows 10, Windows 11 or Linux without a disc drive.

5400 Mbps aggregate throughput headroom

The 160 MHz channel width and 1024-QAM modulation give enough bandwidth for 4K streaming, large file transfers and low-latency gaming when paired with a compatible tri-band router. The 6 GHz band provides clean spectrum but requires a 6E-capable access point. Systems without a free PCIe slot or without 6 GHz infrastructure cannot use the highest speeds.

Questions about this item

Will the 5 dBi antennas on this WN675X3-C need periodic replacement?

The two external 5 dBi antennas are fixed hardware and do not require scheduled replacement under normal use.

What throughput ceiling appears first on the 6 GHz band during long transfers?

The 6 GHz radio tops out at 2400 Mbps, so that link rate becomes the limiting factor before the PCIe interface saturates.

How hot does the Intel AX210 chipset run inside a closed case all day?

Operating temperature is rated 0 °C to 40 °C; the included heat sink keeps the AX210 within that range during continuous load.
