Broadcom BCM943228Z dual-band Wi-Fi card

This Broadcom BCM943228Z adapter fits an M.2 slot and provides 802.11 B/A/G/N wireless connectivity on 2.4 GHz and 5 GHz bands. It is suited for small-form-factor desktops or embedded systems that need basic wireless networking. The card delivers a maximum link rate of 300 Mbps for everyday internet and local file transfers.

Sustained throughput on 2.4 GHz and 5 GHz

Under continuous load the link remains stable on both frequency bands without thermal throttling. The 300 Mbps ceiling is shared across active streams so extended downloads or streaming sessions stay within that envelope. Buyers who need multi-gigabit speeds or newer Wi-Fi standards should consider a different adapter.

Questions about this item

Will the BCM943228Z adapter draw much power or run hot during continuous use?

The BCM943228Z is a low-power PCI Express mini card designed for typical laptop thermal envelopes, so it adds minimal heat and draws only the modest current the slot provides.

Does my laptop need an M.2 Key E slot and antenna cables to use this BCM943228Z card?

Yes, the card fits an M.2 Key E (PCIe mini) connector and requires two attached antenna cables for the 2.4 GHz and 5 GHz bands to function.
