Desktop Wi-Fi 6 upgrade

This PCIe adapter adds Wi-Fi 6 and Bluetooth 5.2 to a desktop PC running Windows 10 or 11 64-bit. It connects through any PCI Express x1, x4, x8 or x16 slot and uses the MediaTek MT7921K chipset. Dual external antennas support 2.4 GHz and 5.8 GHz bands with WPA3 security.

Home and office desktops needing modern wireless

The card suits builders who want AX1800-class speeds and MU-MIMO efficiency for streaming or general networking. It is not for systems without a free PCIe slot, for Linux or macOS environments, or for buyers who need 6 GHz band operation.

80 MHz channel requirement for peak 5 GHz rate

The 1200 Mbps figure on the 5.8 GHz band is only reached when the router operates on an 80 MHz channel width. If the access point uses a narrower channel, the maximum throughput will be lower.

Questions about this item

Will the external dual-band antennas need replacement after extended use?

The dual-band external antennas are detachable; they can be swapped if damaged, but no periodic replacement schedule is required.

What thermal limit appears first when the MT7921K chipset runs at 1200 Mbps on 5.8 GHz all day?

The card relies on passive heatsink cooling; sustained 5.8 GHz throughput is limited by the chipset thermal throttle point rather than a fan curve.

How much extra power does Bluetooth 5.2 draw when the adapter stays active 24/7?

Bluetooth 5.2 runs over the internal USB link and adds only milliwatts to the PCIe slot draw, so total power stays within standard slot limits.
