DELL DW1705 M.2 Wireless Card

This DELL DW1705 C3Y4J is an M.2 Wi-Fi adapter built for internal laptop installation. It serves as a direct replacement part for compatible Dell notebooks such as the Inspiron 3737. The card restores wireless LAN connectivity when the original module fails or is missing. Condition is new and unused.

Suits Dell laptops with matching M.2 keying

Buyers repairing a Dell Inspiron 3737 or another model that accepts this exact part number will find it fits the slot and antenna connectors. Systems requiring a different key layout, a newer Wi-Fi standard, or a combined Wi-Fi and Bluetooth module cannot use this card. Shoppers needing those features should look elsewhere.

M.2 interface decides compatibility

The single specification that determines fit is the M.2 interface itself. Only laptops wired for this connector and keying will accept the adapter. Verify the service manual or original part number before purchase because no other detail overrides the physical interface.
