Dell NC293 Wireless 3945 Minicard

This Dell NC293 Wireless 3945 PCIe Minicard adds wireless networking to compatible laptops or small-form-factor systems. It installs in a standard Mini PCIe slot and is suited for users who need to restore or add Wi-Fi capability to supported hardware. The module is supplied new and ready for installation.

Replaces failed or missing Mini PCIe wireless cards

The card serves as a direct replacement when an existing Wireless 3945 adapter has failed or was not originally fitted. The upgrade is worthwhile when the host device has a free Mini PCIe slot and supports this specific module. It does not suit systems that require a newer Wi-Fi standard, a different form factor such as M.2, or a wired Ethernet interface.

The card is a standard PCIe Mini Card form factor designed for a half-height Mini PCIe slot with a 52-pin edge connector.
