Dell Wireless-N 1000 card for Alienware and XPS

This Dell 112BNHMW Wireless-N 1000 card is a new replacement part for select Alienware, Inspiron, XPS and Vostro laptops. It restores Wi-Fi connectivity on systems where the original adapter has failed or is missing. The card uses a standard Mini PCIe interface for internal installation.

Mini PCIe form factor decides fit

The single specification that determines compatibility is the Mini PCIe form factor combined with the specific model whitelist. This card fits only the listed Dell models including Alienware M17xR3, M11xR3, M14x, Inspiron 13R, 14R, 15R, 17R, XPS 14, 15, 15z, 17 and Vostro 3450, 3750. Other laptops will not recognise the device.

Low power draw and silent operation

As a passive component with no moving parts, the card adds negligible heat and produces zero noise during normal use. Power consumption is minimal and drawn directly from the laptop slot, so it does not affect battery life in any noticeable way. Thermal output remains well within the cooling capacity of the supported chassis.

Questions about this item

How does the Wireless-N 1000 rating translate to actual throughput in a laptop?

The card uses the Intel Centrino Wireless-N 1000 chipset, so real-world speeds depend on the router and antenna quality in the specific Dell model you install it in.

What interface does the card use and what bandwidth limit does that impose?

It connects via a Mini PCIe slot, which limits the link to the bandwidth available on that bus in the supported Alienware, Inspiron, XPS and Vostro notebooks.

Will the card fit my Dell laptop without extra brackets or adapters?

The module is a standard half-height Mini PCIe card designed for the listed Alienware M11xR3, M14x, M17xR3 and the listed Inspiron, XPS and Vostro models, so it fits the factory slot directly.
