Dell Wireless 370 Adapter

The Dell Wireless 370 is a Mini PCI-E network card identified by part number 633ANHMW. It provides 802.11n wireless connectivity for compatible Dell Precision and Alienware laptops. The card uses a half-height form factor designed for specific internal slots. It is intended for owners of supported Dell mobile workstations seeking a direct replacement wireless module.

Compatibility Check Required

Verify that your laptop has an available Mini PCI-E half-height slot before ordering. Confirm the existing wireless card uses the same interface and antenna connector layout. Ensure the system BIOS whitelist accepts this specific Dell part number 4W00N. The adapter is listed for Precision M6600 and Alienware M17x R2 models only.

Direct Replacement Upgrade

This card replaces a failed or missing Wireless 370 module in the supported Dell Precision M6600 and Alienware M17x R2 systems. It restores original 802.11n wireless capability without changing the laptop hardware platform. The jump is worth it when the original card has failed or when a factory-configured wireless option was not installed. Buyers needing newer Wi-Fi standards or different form factors should look elsewhere.
