After you upgrade your computer to Windows 10, if your 3Com Network / Ethernet Drivers are not working, you can fix the problem by updating the drivers. It is possible that your Network / Ethernet driver is not compatible with the newer version of Windows.
There are two ways to update drivers.
Option 1 (Recommended): Update drivers automatically - Novice computer users can update drivers using trusted software in just a few mouse clicks. Automatic driver updates are fast, efficient and elimate all the guesswork. Your old drivers can even be backed up and restored in case any problems occur.
Option 2: Update drivers manually - Find the correct driver for your Network / Ethernet and operating system, then install it by following the step by step instructions below. You’ll need some computer skills to use this method.
