To find the newest driver, you may need to visit the Keyspan website. Most major device manufacturers update their drivers regularly.
After you get your new driver, you need to put it on your computer. On Windows, there's a tool called Device Manager that helps with this. It shows you all the parts of your computer and the drivers they use. To finish setting up the new driver, you'll probably need to turn your computer off and on again.
Tech Tip: Driver downloads and updates come in a variety of file formats with different file extensions. For example, you may have downloaded an EXE, INF, ZIP, or SYS file. Each file type has a slighty different installation procedure to follow.
