2] Uninstall Network driver
If you use an external Ethernet adapter to connect your laptop to your Ethernet connection, there is a high chance of getting this error. As some of the new drivers do not comply with the external Ethernet adapter or network adapter, they often show the BSOD while accessing your computer.
That is why we recommend uninstalling the network driver from your Windows 11 computer as soon as possible. To uninstall the network driver, follow these steps:
First, open the Device Manager and expand the Network adapters section. Right-click on the network driver and select the Uninstall option.
Then, select the “Delete the driver software for this device” option and click the “Uninstall” button.
