Resolving Ethernet and WiFi Issues After a BIOS Update

To address connectivity difficulties following a BIOS update, consider executing these troubleshooting steps:

Step 1: Perform a Hard Reset

Initiate a hard reset of your computer by following these steps:

Shut down your device.
Disconnect the power cable from the outlet or remove the charger from your laptop.
Press and hold the power button for approximately 30 seconds.

Step 3: Reset BIOS to Default Settings

Resetting your BIOS may resolve configuration changes made during the update. Document any existing custom settings before proceeding:

Restart your computer and enter BIOS setup (usually by pressing F2, Del, or Esc during boot).
Find the option to restore default settings, select it, then save and exit.

Pro Tip: After restoring defaults, you may need to adjust settings according to your preferences.

Step 4: Clear the CMOS

Clearing the CMOS can help reset your motherboard settings entirely:

Open your computer case and locate the round battery on the motherboard.
Remove the battery carefully and wait a few minutes before reinserting it.
Close the case and reboot your system.

Step 5: Enable OnBoard LAN in BIOS

Check the OnBoard LAN configuration in the BIOS settings:

Navigate to the Onboard Devices Configuration section in BIOS.

If the driver is incompatible with the new BIOS, the following steps can help:

Open Device Manager.
Expand the Network adapters section.
Right-click your Network Adapter and select Uninstall device.
Restart your computer or perform a hardware scan to reinstall the driver automatically.

Pro Tip: If the problem persists, manually download and install the latest driver from the manufacturer’s website.

If none of the above solutions work, consider resetting your PC:

Go to Settings > Update & Security > Recovery.
Select Get started under Reset this PC.
Choose the “ Keep my files ” option.
