How to Update the Drivers for Realtek PCIe GBE Family Controller for Windows 7
Realtek PCIe GBE Family Controllers comprise a series of network interface controllers -- wired Ethernet cards that provide network connectivity -- produced by Realtek. As with any wired Ethernet card, a Realtek PCIe GBE Family Controller installed on your Windows 7 PC must have the newest Windows 7 drivers to perform at full capacity. If you are having network problems with your wired Internet connection, you may need to update the drivers for your network card. Realtek always offers the latest drivers for its controllers online, and you can download and install them yourself.
Click the Windows 7 “Start” menu button and type “Device Manager” in the search bar. Click the “Device Manager” link under Control Panel in the search list that pops up.
Double-click “Network adapters” until you see the list expand, right-click “Realtek PCIe GBE Family Controller” and select “Properties.”
Click the “Driver” tab and note the driver version for the device.
Go to the Realtek Downloads website (see Resources) and locate the most recent driver version for Windows 7. If the driver date and version matches the one installed on your PC, your computer is already running the most up-to-date driver. If not, choose one of the site-specific download links for the auto-installation option and save the file to your PC.
Double-click the compressed ZIP file to access its contents, and then double-click the Setup.exe file to run the auto-installer.
Select “Repair” from the option list and click “Next.” Windows 7 will install the new drivers.
Click “Finish” to exit the program.
