Genuine Dell DW1705 Half-Height Mini-PCIe Wireless

This genuine Dell DW1705 half-height Mini-PCI Express card adds 802.11b/g/n wireless connectivity to supported Dell laptops. It carries Dell part number C3Y4J and is supplied in new condition. The adapter fits the half-height Mini-PCIe slot found in many Inspiron, Latitude and Vostro models. Installation restores or upgrades the factory wireless capability.

For Dell Laptop Owners Needing a Direct Replacement

This card suits owners of listed Inspiron, Latitude and Vostro notebooks that originally shipped with the DW1705 module. It is not for machines that require a full-height Mini-PCIe card or an M.2 Key-E wireless module. Buyers whose laptop uses a different form factor or antenna configuration should look elsewhere. The part is also unsuitable for desktop PCs lacking a compatible half-height slot.

Half-Height Mini-PCI Express Form Factor

The single specification that determines compatibility is the half-height Mini-PCI Express interface. Only laptops designed for this exact card size and connector will accept the adapter. Verify the service manual for your specific model before purchase. The supported model list includes numerous Inspiron, Latitude and Vostro systems.

Questions about this item

Does the DW1705 C3Y4J come with antennas or mounting screws, or must they be sourced separately?

The card is supplied alone; antenna cables and retaining screws are reused from the laptop or purchased separately.

Should I choose the half-height Mini-PCIe version or an M.2 variant for my Inspiron 15 3521?

The DW1705 C3Y4J is a half-height Mini-PCIe card, which matches the slot in the Inspiron 15 3521.

What real-world Wi-Fi speed can I expect from the 802.11b/g/n rating once installed in a Latitude 3540?

The adapter supports up to 802.11n rates; actual throughput depends on router capabilities, channel width and signal quality.
