Genuine Dell Intel 6250 Wi-Fi card
This is a genuine Dell original Intel Centrino Advanced-N 6250 wireless adapter that adds Wi-Fi and WiMAX to compatible Dell laptops. It fits the half-height Mini PCI Express slot used by many Latitude, XPS, Precision, Studio, Inspiron and Alienware models listed by Dell. Buyers who need Bluetooth or newer Wi-Fi standards cannot use this card.
Half-height Mini PCI Express interface
The card installs only in a half-height Mini PCI Express slot; full-height or M.2 slots will not accept it. Dell part number MW04C confirms the exact form factor required for the supported laptop families. If your machine uses a different wireless slot, this adapter will not fit.
Simple internal installation
Installation requires opening the laptop, locating the wireless card slot, inserting the card at an angle and securing it with one or two screws. Antenna cables must be snapped onto the card connectors; loose cables are the most common reason for weak signal after fitting.

Questions about this item
What does the 270 Mbps 802.11n link rate mean for real-world throughput on this card?
Expect roughly half that figure in sustained data transfer once overhead, interference and distance are factored in.
How does the PCI Express Half Mini Card interface limit performance compared with newer slots?
The single-lane PCIe Gen 1 connection caps total bandwidth well below the wireless PHY maximum, so the bus is not the bottleneck.
Will this half-height Mini-PCIe card fit a full-height slot without an adapter bracket?
No, the card is half-height; a full-height bracket or riser is required to secure it in a standard Mini-PCIe slot.
