Dell DW1820 M.2 wireless card

This Dell DW1820 card adds dual-band 802.11ac Wi-Fi and Bluetooth to compatible systems through a single M.2 slot. It uses the Qualcomm QCA61X4A controller and carries Dell part number D4V21. The adapter fits many Dell laptops and desktops listed by the manufacturer.

Who this suits and who it does not

The card suits owners of the listed Latitude, Precision, Vostro, Inspiron, Alienware, G Series and OptiPlex models who need to replace a failed module or add wireless to an empty M.2 keyed slot. It is not for systems that lack an M.2 Wi-Fi slot, that use a different keying, or that require a newer Wi-Fi standard than 802.11ac.

Deciding specification

The single specification that decides fit is the M.2 form factor combined with the exact Dell part number D4V21; only models documented by Dell as compatible with this part number will accept the card.
