BCM43602KMLG Chip Not Working After a System Update? Troubleshooting Tips

If your BCM43602KMLG Wi-Fi chip isn't working after a system update, don't worry—you're not alone. Many users experience hardware issues following an update due to a variety of reasons, including driver incompatibility, configuration changes, or conflicts with the new operating system features. Here’s a step-by-step guide to help you identify and fix the problem.

Possible Causes of the Issue

Driver Incompatibility System updates may install a new version of drivers that are incompatible with the BCM43602KMLG chip. This can cause the chip to stop working or perform erratically. Firmware Changes The system update might have altered settings in your computer's BIOS or the firmware of the Wi-Fi card itself, disabling its functionality. Operating System Update Bugs Sometimes, an update can introduce bugs or cause conflicts with other system processes, which could result in the Wi-Fi chip not being recognized. Power Management Settings Updates might reset Power Management settings, causing the device to go into a low-power state where the Wi-Fi chip is not enabled. Network Configuration Changes New updates might also alter network settings, causing your computer to have trouble connecting to your Wi-Fi network or detecting available networks.

Step-by-Step Troubleshooting and Solutions

1. Check Device Manager for Issues Press Win + X and select Device Manager. Expand the Network Adapters section and locate the BCM43602KMLG chip. If there's a yellow warning triangle next to the device, right-click it and select Update Driver. If there is no update available, try Uninstalling the Device and then restarting your computer. Windows will automatically reinstall the drivers. 2. Update or Reinstall the Driver Go to the manufacturer's website for your Wi-Fi card or the laptop’s support page and download the latest driver for the BCM43602KMLG. Install the updated driver manually if the automatic update didn’t fix the issue. After the installation, restart your computer and check if the issue is resolved. 3. Roll Back the Driver If the issue started after a specific update, the new driver may be incompatible. In Device Manager, right-click the BCM43602KMLG chip, select Properties, and go to the Driver tab. Click Roll Back Driver to revert to the previous version. If the option is grayed out, it means there’s no previous driver to roll back to. In that case, manually download an older version from the manufacturer's website. 4. Check Power Management Settings Sometimes, system updates reset power management settings, causing the Wi-Fi chip to be turned off. In Device Manager, right-click the BCM43602KMLG chip and go to Properties. Under the Power Management tab, uncheck Allow the computer to turn off this device to save power and click OK. Restart the computer and check if the Wi-Fi chip works. 5. Reset Network Settings If there were changes in network settings during the update, you can reset them: Go to Settings > Network & Internet > Status. Click on Network Reset at the bottom. Follow the prompts to reset your network settings. After resetting, you may need to reconnect to your Wi-Fi network. 6. Check for System Updates Sometimes the system update itself may have bugs. Make sure your system is fully updated with any fixes that might address Wi-Fi issues. Go to Settings > Update & Security > Windows Update and check for any available updates. Install them and restart your computer. 7. Check BIOS/Firmware Settings System updates might change BIOS or firmware settings, which could affect hardware components like your Wi-Fi chip. To access the BIOS, restart your computer and press the appropriate key (usually F2, F10, or DEL) during boot. Look for any settings related to wireless or power management and ensure they are enabled. 8. Test on Another Device or Operating System If possible, test the BCM43602KMLG chip on another device or operating system to see if the issue persists. This can help determine if the issue is with the hardware itself or specifically with your system's update.

If All Else Fails: Consider Reverting the System Update

If none of the above solutions work and you suspect the update itself caused the issue, consider reverting to a previous system restore point. Go to Control Panel > Recovery > Open System Restore and follow the prompts to restore your system to a point before the update. This should undo any changes made during the update that might have affected your Wi-Fi chip.

Conclusion

In summary, if your BCM43602KMLG Wi-Fi chip stops working after a system update, the issue could be related to driver compatibility, system settings changes, or network configuration problems. Follow the troubleshooting steps outlined above to resolve the issue, and if needed, revert your system to a previous state before the update. By systematically addressing these possible causes, you should be able to restore functionality to your Wi-Fi chip and get back online.
