DW1540 BCM943228HM4L 300 Mbps Wi-Fi adapter

This M.2 wireless card uses the DW1540 BCM943228HM4L module to provide dual-band 802.1a/b/g/n connectivity at up to 300 Mbps. It is built for Dell Latitude 6430u and compatible models including 1320, 1440, 1458, 1647 and 1745. The 3676J part number identifies the specific Dell-qualified revision. Buyers who need 5 GHz AC or AX speeds cannot use this card.

Mini PCIe interface limits upgrade options

The adapter fits a mini PCIe slot rather than a modern M.2 key-E socket, so it will not install in newer ultrabooks or desktop boards that only provide M.2 wireless slots. The 802.1n standard caps throughput at 300 Mbps and lacks the wider channels and spatial streams of later amendments. Systems without a whitelisted BIOS entry for the 3676J part may block the device at boot.

Questions about this item

Should I pick the 300 mbps version for my Dell Latitude 6430u?

The 300 mbps DW1540 is the only version listed and matches the 6430u in the compatibility list.

What does the 300 mbps figure mean once the card is installed in a Dell 1440?

It is the maximum link rate defined by the 802.1 standard; actual throughput depends on router capability and local interference.
