If you have a network in your home or office, you may use Ethernet cards to connect to that network. Ethernet cards have a number of advantages, including variable speed settings and the fact that most new computer equipment supports the Ethernet standard by default. At times, however, the speed on your Ethernet card can slow down. When that happens, it is best to use a step-by-step approach to resolve the issue.
Shut down your computer and restart it. Over time, memory leaks can occur as your programs run, and those memory leaks can slow down your system and reduce your network connection speed. Physically shutting down the computer and restarting it frees up these resources and allows your computer to perform faster.
Go to the website of the Ethernet card manufacturer and check for updated drivers. The manufacturer may release new drivers that address issues with slow connection speeds and memory problems.
Click the "Start" button on your computer's desktop. Choose "Settings" followed by "Control Panel." Double-click the "Network" icon, and then select the "Local Area Network" option.
Right-click the "Network" icon and choose "Properties." Click the set-up button for your network card, and check the speed and duplex settings. Set the speed to the highest speed supported by your home or office network. If you are working with a home network, check the documentation you received from your ISP or the manual that came with your network hub. If you are working in an office, contact your network administrator before making any changes to the speed of the network card.
Click the "Speed and Duplex" button. Use the drop-down box to change the duplex setting to "Full." The full duplex setting can speed up the performance of the network card and boost the speed at which you connect.
