The Broadcom BCM94312HMG is a wireless network adapter commonly found in laptops and mini-PCI/PCIe cards. It implements 802.11b/g Wi‑Fi (some variants support draft‑n modes depending on firmware) and uses Broadcom chipset firmware. Proper operation requires both a kernel driver and correct firmware/blobs; on many systems driver availability and the legal distribution of firmware affect usability.
