HP RT5392 Half-Mini Wi-Fi Adapter

This HP RT5392 adapter provides 802.11b/g/n wireless connectivity in a half-mini form factor for compatible laptops. It uses an M.2 interface and carries part number 640823-001 for exact identification. The card is supplied new without cables or manuals.

Who this suits and who it does not

This card suits owners of laptops that accept a half-mini M.2 Wi-Fi module and require 802.11b/g/n support. It will not fit systems that need a full-size mini-PCIe card or a different keyed M.2 connector. Buyers who need Bluetooth, 5 GHz 802.11a or newer Wi-Fi standards should look at other adapters.

Deciding specification

The defining specification is the half-mini M.2 form factor combined with 802.11b/g/n capability. Verify that your service manual lists part number 640823-001 or the RT5392 model before ordering.

Questions about this item

Does the half-mini card require any antenna cables or brackets that are not included?

The listing states no accessories such as cables or manuals are included unless otherwise noted, so plan to reuse existing antenna leads and mounting hardware.

Which wireless standard will cap throughput first during sustained transfers?

The adapter tops out at 802.11n speeds, so that PHY ceiling will be the bottleneck before any other component.

How much heat or power draw should I expect when the card runs continuously?

Typical half-mini Wi-Fi modules draw only a few watts and stay cool under normal laptop airflow; no active cooling is required.
