The Broadcom BCM43228 driver allows Windows to communicate with this wireless network adapter, enabling your PC to detect nearby Wi-Fi networks and connect to the internet. Installing a suitable driver can help resolve an unrecognized adapter, missing wireless options, or connection problems caused by an incorrect driver. For Windows 11, 10, 8, or 7, check that the download matches your system version and hardware before installing.

Key Features

• Wireless network access: Provides the software interface needed for the Broadcom BCM43228 to discover and join compatible Wi-Fi networks.
• Windows networking integration: Lets you manage wireless connections through the operating system’s network settings.
• Adapter recognition: Helps Windows identify the device correctly in Device Manager rather than listing it as an unknown network controller.
• Connection troubleshooting: Replacing a missing, damaged, or mismatched driver may restore wireless functionality and address driver-related disconnections.

How to Install

1. Confirm your adapter and Windows version. Open Device Manager and look under Network adapters for the Broadcom BCM43228. If it appears as an unknown device, check its hardware IDs under Properties > Details. Also confirm whether your Windows installation is 32-bit or 64-bit.

1. Choose a compatible driver package. Review the package’s supported hardware and operating systems. A driver intended for Windows 7 or 8 should not automatically be assumed compatible with Windows 10 or 11; manufacturer support can vary by computer model and driver release.

1. Download and extract the files. Save the package to your computer and extract it if it is compressed. If Wi-Fi is unavailable, use Ethernet or transfer the download from another device using a USB drive.

1. Install the driver. Run the included installer and follow its prompts. If there is no installer, right-click the adapter in Device Manager, select Update driver, choose Browse my computer for drivers, and point Windows to the extracted folder.

1. Restart and test the connection. Restart your PC if requested, then connect to your wireless network. If the adapter stops working after the update, use Roll Back Driver in its Device Manager properties when that option is available, or reinstall the previous working package.

Common Issues and Fixes

• Install fails or rolls back: Run the Broadcom package as administrator; if it still fails, extract the INF and use Device Manager > Update driver > Browse > “Have Disk.” Check for Code 10/28 errors and install the correct 32/64-bit package.
• Adapter not detected or disappears: Enable WLAN/Wi-Fi in BIOS, check the hardware wireless switch/airplane mode, and reseat the BCM43228 mini PCIe card. In Device Manager, show hidden devices and scan for hardware changes; a Code 45 often clears after a full power-off restart.
• Version conflicts or poor performance: Uninstall any existing Broadcom 802.11n driver and delete its software, reboot, then install one matching OEM/generic package only. Avoid mixing INF versions. If Windows Update replaces it, roll back the driver; enable 802.11n and 20/40 MHz only if your AP supports it.
