If it is working reliably and properly now, just make sure you do not allow Windows Update or any other resource to change or "update" the driver. Sometimes integrated network adapters can be so proprietary that even a driver from the actual device manufacturer can cause problems and they will only work properly with drivers provided by your laptop manufacturer. It's rare but it does happen.
To prevent Windows Update from installing unwanted hardware device drivers, right click computer and choose properties.
From the left column choose Advanced system settings.
Select the Hardware Tab
Then the Device Installation Settings button
Select the No, let me choose what to do radio button
Then the Never install driver software from Windows Update.
