Dell DW1397 Wireless Card

The Dell DW1397 is a Broadcom 4312 wireless card built for the Mini PCI Express slot. It targets owners of listed Inspiron, Latitude, Precision and Studio laptops who need a direct replacement for a failed or missing original module. Buyers whose systems use a different slot type or whitelist an unsupported part number cannot use this card.

Mini PCI Express Interface Limits

The card fits the Mini PCI Express connector found in the compatible Dell models listed in the specifications. Bandwidth and protocol capability are defined by the Broadcom 4312 chipset and the host system implementation. Laptops outside the validated model list may not recognise the device or may block it at BIOS level.

Installation Notes

Installation requires opening the laptop chassis to access the Mini PCI Express slot and attaching the antenna cables to the card connectors. The most common issue is a BIOS whitelist that prevents the system from booting with an unapproved part number. Antenna lead routing and connector orientation can also cause weak signal if not seated correctly.
