To tell if your computer's network card is a Gigabit network card, you can check it by following these steps:
1.View Device Manager:
Right-click on "This PC" and select "Manage".
Find Device Manager in Computer Management.
Expand Network Adapters and find your network card.
Right-click on the NIC and select "Properties".
Switch to the Advanced tab and look for the Speed & Duplex properties.
2.Check NIC Properties
If you see a "10 GB s", "1000Mbps", or similar Gigabit rate options, then your network card is a Gigabit network card.
If you only see 100Mbps or 10 100Mbps options, then it may be a 100Mbp LAN.
3.Observe the NIC description:In the description of the NIC in the device manager, some key information is usually included, such as "gigabit", "gbe", "10 100 1000M", etc., which indicate that the NIC supports gigabit speeds. If it contains words such as "fast ethernet", "10 100", "fe", etc., it may be a 100 Gigabit network card.
4.Network connection speed:Although it is not very accurate to judge the type of network card by the speed displayed by the local connection status (such as 100M), if it is displayed as 1G or 1000M, it is more likely to be a Gigabit network card.
5.Check the NIC specificationsYou can also consult the NIC's technical specifications or the manufacturer's official **, which usually clearly indicates the maximum transfer rate of the NIC.
6.Use the network testing tool:Use a network performance testing tool, such as iperf, to actually test the speed of your network connection to determine if the network card is reaching gigabit speeds.
In short, through the above methods, you can accurately determine whether the network card of the computer is a gigabit network card. If you are still unsure after these checks, you can consult a professional technician or contact the manufacturer of the network card for assistance.
