What should I do if the network speed is slow after upgrading the fiber? Reasons and solutions for slower fiber optic network speed

With the popularity of fiber-optic networks, many family friends today use 20M/50M or even 100M fiber-optic networks. However, some friends complained that after upgrading the fiber-optic broadband, the computer Internet speed slowed down. What is going on? A few days ago, some telecom engineers found a reason, mainly caused by the NIC problem. Here, I will teach you how to slow down the fiber network.

Step 1: Right click on the network icon in the lower right corner of the desktop, then click “Open Network and Sharing Center", then find “local connection”, then right click on it , open “properties & rdquo;, as shown.

Step 2: In the open local connection properties interface, click “Config & rdquo; as shown.

Step 3: Finally, in the NIC advanced property setting interface, click to select the connection speed and duplex mode on the left side, then on the right side. Select “100Mbps full duplex” in the value, and when finished, click ““OK” below to save the settings.

By the above settings, you can let the network card fully play the 100M network speed function, and finally test the fiber speed is a lot faster?

Note: If your computer uses a wireless network, you can set the network card duplex mode on the wireless network connection according to the above method.

The above is the reason and solution for the slow speed of the fiber after upgrading the fiber. I hope it will help everyone. If your home broadband upgrades the fiber above 20M, the speed of the network is not obvious or it is not as good as before. Mega network speed, then it may be caused by the network card duplex mode did not switch to high-speed mode, go try it.
