Half Mini PCIe Wi-Fi adapter for select laptops

The YINGHUA RT5390 is a half-size Mini PCIe wireless card delivering 150Mbps over 802.11n. It targets owners of compatible notebooks such as the 436, CQ45, G4, 4340S and 4445s models who need a direct replacement for a failed or missing module. The compact 22 by 30mm form factor fits the half-height slot found in those systems.

Replaces original SPS 670691-001 or 691415-001 cards

This adapter matches the OEM part numbers listed for the referenced laptop families. The upgrade is worthwhile when the factory wireless card has failed, when the original antenna cables are intact, and when 150Mbps 802.11n coverage meets the current network environment. It is not suited for machines requiring full-height Mini PCIe or M.2 Key E modules.

Fits half-height Mini PCIe slot

Installation requires an available half-size Mini PCIe socket and two U.FL antenna connectors already routed in the chassis. The card draws minimal power from the slot and uses standard 802.11n drivers supplied by the operating system. It frees the user from USB dongles and restores internal wireless without occupying a USB port.

Questions about this item

Will the half-size Mini PCIe card fit the 22 x 30 mm slot in my laptop?

The adapter measures approximately 22 x 30 mm, matching the standard half-size Mini PCIe footprint used in compatible models.

What is the correct way to seat the Mini PCIe connector and secure the card?

Insert the card at an angle into the Mini PCIe slot, press down until the connectors engage fully, then fasten the retaining screw to lock it in place.

How often should I clean the gold contacts on the RT5390 card?

Contacts rarely need cleaning; if signal drops occur, gently wipe the edge connector with a lint-free cloth and reseat the card.
