Dell DW1901 AR5B22 wireless card

This Dell DW1901 card uses the Atheros AR5B22 chipset to provide 802.11 a/b/g/n Wi-Fi and Bluetooth over a Mini PCI Express interface. It is an add-on card designed for compatible Dell laptops. The part number K2GW5 identifies this specific OEM module.

Suits owners of listed Dell models

The card suits owners of Inspiron, Vostro or XPS laptops that have a free Mini PCI Express slot and need factory-compatible wireless hardware. Builders whose chassis lack a Mini PCI Express connector or who require a different form factor cannot use this card.
