Step 3: Update the Driver Right-click the wireless device and select Update driver . Choose Browse my computer for drivers .

Firmware predates WPA3; SAE handshake must be handled in software. Our driver offloads only WPA1/2.

If you managed to download an old .exe installer file (perhaps meant for Windows 7 or Vista) but it refuses to run on a newer OS, you need to use Compatibility Mode.

Windows Update often has a generic driver that can get the card working. You can force Windows to search for it by: broadcom bcm94312hmg driver

sudo tee /etc/modprobe.d/blacklist-bcma.conf <<< "blacklist bcma"

Linux distributions support the BCM94312HMG using open-source or proprietary Broadcom drivers. The card requires the installation of firmware to operate.

Linux distributions (like Ubuntu, Debian, Mint, or Fedora) handle Broadcom chips using one of two driver architectures: the open-source b43 driver or the proprietary wl (Broadcom STA) driver. For the BCM4312 (LP-PHY) variant inside the BCM94312HMG, the open-source firmware installer is highly recommended. On Ubuntu / Linux Mint / Debian Connect your machine to the internet via Ethernet. Open your terminal and purge any conflicting STA drivers: sudo apt-get purge bcmwl-kernel-source Use code with caution. Update your package repository: sudo apt-get update Use code with caution.
