HP RT5390 Wi-Fi Adapter

The HP RT5390 is a new wireless network adapter that uses the M.2 form factor and supports the 802.11bgn standard with a single spatial stream. It is intended for owners of compatible HP Pavilion All-in-One 20 Series systems who need to replace a failed or missing wireless card.

Replaces Mini PCIe Card 690980-001

This part supersedes the earlier 690980-001 Mini PCIe card, moving the connection to an M.2 slot while keeping the same 802.11bgn 1x1 capability. The change is worthwhile only when the target system has an M.2 keyed slot wired for Wi-Fi and the original Mini PCIe card is no longer an option.

Simple M.2 Installation

Installation requires opening the All-in-One chassis, locating the M.2 Wi-Fi slot, and securing the card with a single screw. The most common issue is antenna cables that are too short or use a different connector type, which prevents a proper connection even when the card fits the slot.
