Broadcom Bcm94312hmg Driver

A: Yes, but only with driver version 7.35.352.0 or newer. You must disable Memory Integrity (Core Isolation) in Windows Security for stable operation.

The BCM94312HMG requires the b43 or brcmsmac driver. Broadcom’s proprietary wl driver (from broadcom-sta) does not support this card.

| Driver | Status | Firmware Required | Notes | |---|---|---|---| | b43 | Fully functional | b43-firmware (or b43-fwcutter) | Best for older kernels | | brcmsmac | Stable (since kernel 3.0) | Built-in (brcmfmac firmware) | Preferred for modern distros | | wl (broadcom-sta) | ❌ Not supported | N/A | Only for newer 43xx chips | broadcom bcm94312hmg driver

Installation (Ubuntu/Debian example):

# Remove conflicting drivers
sudo modprobe -r b43 ssb bcma wl brcmsmac
The BCM94312HMG is supported by the brcmsmac (open source) driver, not the proprietary wl (broadcom-sta) driver. Using wl will cause kernel panics. A:  Yes, but only with driver version  7
Ubuntu/Debian:
sudo apt update
sudo apt install firmware-b43-installer
sudo apt remove bcmwl-kernel-source
sudo reboot

Fedora:
sudo dnf install broadcom-wl
# Note: For BCM94312HMG, you may need to blacklist wl in favor of brcmsmac.

Arch Linux:
sudo pacman -S broadcom-wl-dkms
# Then blacklist wl and load brcmsmac

Firmware predates WPA3; SAE handshake must be handled in software. Our driver offloads only WPA1/2. Fedora: sudo dnf install broadcom-wl # Note: For
