DELL DW1075 Wi-Fi adapter 802.11 a/b/g/n

SKU CH-2KTS-7A0FD MPN DW1075

Half-height Mini PCIe module adds 802.11 a/b/g/n wireless to compatible Dell laptops

  • TypeM.2 Wi-FI Adapter
  • Half-height Mini PCIe fits slim laptops
  • 11 a/b/g/n supports dual-band networks
  • Genuine Dell part 05GC50 ensures compatibility
  • Pulled from new system for tested reliability
  • Qualcomm Atheros chipset delivers stable wireless performance

Compatible Dell Mini PCIe Wi-Fi Adapter

This Dell DW1075 wireless adapter fits Mini PCI Express half-height slots in compatible Inspiron laptops. It supports 802.11 a/b/g/n connectivity for standard wireless networking. The card is genuine Dell hardware pulled from new systems.

Replaces Failed or Missing Wireless Card

Use this module to replace a defective DW1075 or equivalent Qualcomm Atheros card in supported Dell models. The upgrade is worthwhile when the original adapter fails or is absent from the factory configuration. It restores 802.11 a/b/g/n capability without changing antenna wiring.

Simple Half-Height Module Installation

Installation requires opening the laptop chassis to access the Mini PCIe slot and attaching the two antenna leads. The half-height form factor fits the designated bay directly. The main risk is damaging the fragile U.FL connectors or routing cables where they can be pinched during reassembly.

Questions about this item

Does this DW1075 module fit an M.2 slot or the older Mini PCI Express half-height connector?

The DW1075 uses an M.2 form factor; it will not fit a Mini PCI Express half-height socket.

Which antenna cables must be connected during installation, and which connector is commonly missed?

Attach both the main and auxiliary antenna leads to the two U.FL ports on the card; the auxiliary port is the one most often left unplugged.

Will the DW1075 need a firmware update or driver reinstall after a major Windows feature upgrade?

Windows Update normally supplies the Qualcomm Atheros driver automatically; a manual reinstall is only required if the adapter disappears from Device Manager.
