Dell DW1704 wireless adapter for Dell laptops
The Dell DW1704 R4GW0 is a half-height Mini PCI Express card that adds 802.11 b/g/n Wi-Fi at 300 Mbps and Bluetooth 4.0 to compatible Dell Inspiron, Latitude, Vostro and XPS models. It fits the Mini PCIe slot found in the listed notebooks and desktops. Buyers whose systems use a different wireless interface or form factor cannot use this card.
Thermals noise and power draw
The card draws power directly from the Mini PCIe slot and operates on the 2.4 GHz band only. No active cooling is required and the module runs silently under normal wireless and Bluetooth workloads. Power consumption remains within the slot specification for half-height Mini PCIe devices.
Bundled software and accessories
The adapter ships as the bare card without antennas, cables or mounting screws; those parts must be sourced from the original system or purchased separately. Dell driver packages for the supported models enable both WLAN and Bluetooth 4.0+HS functionality once installed. No additional utilities or management applications are included.

Questions about this item
How do I install the DW1704 R4GW0 half-height Mini PCIe card in a Dell laptop, and what step is often missed?
Power off the laptop, remove the battery, open the Mini PCIe slot cover, insert the card at an angle and press down until the clips click, then attach the two antenna cables to the MAIN and AUX connectors — the step often missed is routing the cables so they do not pinch when the cover is replaced.
What maintenance or replacement will the DW1704 R4GW0 need over time?
The card itself has no moving parts and requires no scheduled maintenance; replacement is only needed if the Wi-Fi 802.11 b/g/n radio or Bluetooth 4.0 module fails, or if you upgrade to a newer wireless standard.
What limit appears first during sustained heavy traffic on the DW1704 R4GW0?
The 300 Mbps 802.11 n single-stream ceiling on the 2.4 GHz band is the first bottleneck, so prolonged large transfers will saturate the link before the PCI Express half-mini-card bus or the Bluetooth 4.0 controller becomes a constraint.
