DELL DW1530 Wi-Fi adapter BCM943228HM4L dual band 2.4GHz 5GHz

SKU CH-3ZME-ATS2A MPN DW1530

Internal half-size Mini PCI Express wireless card supporting dual-band 2.4 GHz and 5 GHz 802.11n connectivity for compatible Dell laptops

  • Dual-band 2.4 & 5 GHz for flexible network selection
  • IEEE 802.11a/b/g/n standard delivers compatible wireless performance
  • Half-size Mini PCI Express form factor fits listed Dell laptops
  • Broadcom BCM943228HM4L chipset provides integrated wireless processing
  • Genuine Dell part 1JKGC ensures direct-fit replacement for supported models

Compatible Dell Latitude upgrade

The DW1530 is a half-size Mini PCI Express wireless card built on the Broadcom BCM943228HM4L chipset. It delivers dual-band 802.11a/b/g/n connectivity across 2.4 and 5 GHz frequencies. The card targets owners of listed Latitude, Precision, Inspiron, Studio, Vostro and OptiPlex models seeking a direct replacement or a step up from a single-band adapter.

Replaces single-band Mini PCIe cards

This module supersedes earlier half-height cards limited to 2.4 GHz only, adding 5 GHz operation for reduced interference in dense environments. The jump is worthwhile when the existing adapter fails, drops connections on crowded channels, or cannot see 5 GHz networks broadcast by modern routers. It fits the same half-size slot and antenna connectors used by the factory-installed part.

Suits listed Dell laptops and OptiPlex desktops

Buyers with a compatible model from the supplied list can install this card without modification. It is not for systems that lack a half-size Mini PCIe slot, use a different keying, or rely on M.2 wireless modules. It also does not serve users needing 802.11ac or newer standards, Bluetooth capability, or three-stream spatial multiplexing.

Questions about this item

Does the DW1530 card use a half-size Mini PCI Express slot?

Yes, it is an internal half-size Mini PCI Express wireless card that fits the standard half-height slot found in the compatible Dell Latitude and Precision models listed.

What is the common mistake when installing this card in a Latitude E6420?

The two antenna cables must be connected to the correct MAIN and AUX connectors on the card; reversing them degrades dual-band 2.4 and 5 GHz performance.

When should I replace the BCM943228HM4L adapter?

Replace it if wireless connections drop frequently, speeds fall well below IEEE 802.11n rates, or the laptop no longer detects any networks on either frequency band.
