The best way to fix your PC to run at peak performance is to update your drivers. If your system is slow, unresponsive or crashes often, the problem may be with your drivers. Sometimes, after upgrading to a newer operating system such as Windows 10, problems can occur because your current driver may only work with an older version of Windows. To download and update your 3Com drivers manually, follow the instructions below.
Tech Tip: Updating drivers manually requires some computer skills and patience. A faster and easier option is to use the 3Com Driver Update Utility to scan your system for free. The utility tells you which specific drivers are out-of-date for all of your devices.
To get the latest 3Com driver, including Windows 10 drivers, you can choose from a list of most popular 3Com driver updates. Click the download button next to the matching model name. After you complete your download, move on to Step 2.
If your driver is not listed and you know the model name or number of your 3Com device, you can use it to Search our 3Com Device Driver Database. Simply type the model into the search box and click the Search button. You may see different versions in the results. Choose the best match for your PC and operating system.
If you don’t know the model name or number, you can start to narrow your search down by choosing which category of 3Com device you have (such as Printer, Scanner, Video, Network, etc.). Start by selecting the correct category from our list of 3Com Device Drivers by Category.
Need more help finding the right driver? You can request a driver and we will find it for you. We employ a team from around the world. They add hundreds of new drivers to our site every day.
Tech Tip: If you are having trouble deciding which is the right driver, try the 3Com Driver Update Utility. It is a software utility that will find the right driver for you - automatically.
After you download your new driver, then you have to install it. To install a driver in Windows, you will need to use a built-in utility called Device Manager. It allows you to see all of the devices recognized by your system, and the drivers associated with them.
In Windows 8.1 & Windows 10, right-click the Start menu and select Device Manager
In Windows 8, swipe up from the bottom, or right-click anywhere on the desktop and choose "All Apps" -> swipe or scroll right and choose "Control Panel" (under Windows System section) -> Hardware and Sound -> Device Manager
In Windows 7, click Start -> Control Panel -> Hardware and Sound -> Device Manager
In Windows Vista, click Start -> Control Panel -> System and Maintenance -> Device Manager
In Windows XP, click Start -> Control Panel -> Performance and Maintenance -> System -> Hardware tab -> Device Manager button
Locate the device and model that is having the issue and double-click on it to open the Properties dialog box.
Select the Driver tab.
Click the Update Driver button and follow the instructions.
In most cases, you will need to reboot your computer in order for the driver update to take effect.
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.
If you are having trouble installing your driver, you should use the 3Com Driver Update Utility. It is a software utility that automatically finds, downloads and installs the right driver for your system. You can even backup your drivers before making any changes, and revert back in case there were any problems.
Try it now to safely update all of your drivers in just a few clicks.
