HP RTL8821CE M.2 wireless adapter

This M.2 wireless adapter uses the Realtek RTL8821CE-CG single chip to provide 802.11ac Wi-Fi with 1-stream Multi-user MIMO and integrated Bluetooth 2.1, 3.0 and 4.2 connectivity. It suits desktop builders adding wireless networking to a compatible motherboard slot.

Replaces missing or faulty internal wireless

The card upgrades a system that lacks built-in Wi-Fi or replaces a failed module using the same M.2 keying. The jump is worth it when a wired connection is impractical and the motherboard exposes a supported M.2 interface for WLAN.

Fits M.2 WLAN slot with PCIe and USB links

Installation requires an M.2 slot wired for PCIe Wi-Fi and USB Bluetooth signals. The single-chip design frees board space by combining radio, baseband and MAC functions without extra antennas or separate Bluetooth hardware.

Questions about this item

Does this M.2 Wi-Fi adapter require a key E or key A slot on the motherboard?

The card uses an M.2 interface with a Realtek RTL8821CE-CG chip that combines WLAN MAC, 1T1R baseband and RF in a single package, so it fits a standard M.2 key E or key A slot.

Which antenna connectors must be attached before the card will work?

The 1T1R design needs one IPEX/U.FL antenna lead connected to the single RF port on the RTL8821CE-CG; without it the 802.11ac link will not function.

How often should the antenna pigtail or the card itself be replaced?

The antenna pigtail can loosen from vibration or heat cycles, so reseat it during any internal service; the card itself has no moving parts and only needs replacement if the RTL8821CE-CG fails.
