Help, I have a gigabit network at home, but my computer actually only has a 100 gigabit network.

It should be a problem with the network card or network cable. If the network cable is too far away from the computer and the network cable is too long, the network speed will drop. If the network card supports Gigabit, it is usually a network cable problem.

Some network cards have higher requirements for network cables, so change to a shorter network cable, connect to the router, and check the network speed.

I have several desktops at home, and these computers have the same model network card and also support Gigabit. The computer that is relatively close to the router can reach Gigabit with a 2-meter-long network cable, and the router is sent by Telecom with Gigabit port. And my room is 10 meters away from the router, with a long network cable, I bought a better network cable, but the computer can only go to 100 megabits.

Changing the full duplex is also disconnected. So I think it's a network cable problem.

A Gigabit discrete network card will solve your problem.

D-Link DGE-560T Gigabit Twisted Pair Cable Remote Wake-up Computer Server Desktop Computer Built-in PCI-E Wired Network Card.

About 100r, you can use the router to power on (if the router supports the feature).

As far as the description, visually inspect the NIC problem. It is recommended to add an independent NIC to try it. Then the network cable can be replaced or redone with the crystal header.

I don't know how to continue asking, satisfied.

Gigabit network cable and double gigabit routing, and then the computer's network card must also be gigabit, which can achieve the effect of gigabit.

You can change the driver of the lower network card to try, there may be a problem with the driver.

The computer network speed only shows 100m is caused by the network not being set correctly, and the method to improve the network speed is:

1. First of all, find the computer or my computer icon on the desktop of the computer.

2. Then right-click the computer or my computer icon, the drop-down menu of the right-click pops up, and we can find "Device Manager" in the menu.

3. Click "Device Manager", the window page of Device Manager will pop up, and we can find "Network Adapter" on the page.

4. Double-click "Network Adapter", and the network card model of our computer will appear.

5. Then double-click on the network card of our computer, and the property window page of our computer network card will pop up, and we can find "Advanced" in the menu at the top of the page.

6. Click "Advanced", you will enter the advanced settings page of the network card properties, and we can find "Speed and Duplex" in the property list on the left side of the page.

7. You only need to check "Speed & Duplex", and then set the value of "Speed & Duplex" to "Full Duplex", so that you can increase the local connection speed from 100M to 1G.

Gigabit broadband becomes 100 Gigabit broadband, why is there only 100 Gigabit after the Gigabit broadband connection router at home, it is normal for this situation to occur, because we use this Gigabit broadband, if it is said that the router does not support Gigabit, then our network is only 100 Gigabit speed.

It is a very normal thing, because this router will limit the network speed, so when we buy this router, we must see if this router supports this gigabit broadband <>

Sometimes the bandwidth we use is very large, but after the router found that the broadband is very slow, that is because some routers do not support a gigabit broadband, so this situation occurs, so we must pay attention when buying a game, some routers do not support gigabit optical state, at this time it will cause our network speed to be very slow <>

For this situation, it may also be because of their own router, although it is said to be able to support a gigabit broadband, maybe the router is broken, so it leads to the connection to the router and find that one of our broadband is only 100 megabits, which is also a possibility to happen, many times as long as the router is broken, there will be this kind of thing <>

In general, the first reason for this situation is that our router does not support a gigabit broadband, and the second reason is because our router is broken, so it will lead to this situation.

It is normal for this situation to occur, because the gigabit broadband we use, if it is said that the router does not support gigabit, the network is only a 100 megabit network speed is a normal thing, because this router will limit the network speed, so when we buy this router, we must see if this router supports this gigabit broadband.

Limitations of the router.

Sometimes the bandwidth we use is very large, but after passing through the router, we find that the broadband is very slow, that is because some routers do not support a gigabit broadband, so this situation occurs, so we must pay attention when we buy a game, there are some routers that do not support gigabit optical state.

It's because the router consumes a certain amount of bandwidth, and a lot of people may connect to your router, you don't know.

It may be because the house you live in is a building, and due to the twists and turns, the signal may be affected in some way.

Because you can't show such a fast internet speed, don't worry about this.

1. First, find the computer icon on the desktop of the computer, then right-click to select Device Manager and click:

2. After entering the new interface, click to select Network Adapter:

3. After that, you can see the network card on the computer, click on it:

4. A new window appears and click Advanced:

5. After that, click to switch the working mode of the network card to 1G Shuangqing answering the work, so that the network card can support gigabit network:

Gigabit network, but the local connection is 100 megabit? What's going on?

Gigabit network, but the local connection is 100 megabit? What's going on? Hello dear, If it is a Gigabit router and the local connection is only 100 Gigabit, then there are two possibilities.

A brief question about the first network cable. It is possible that the network cable is a category 4 cable. In this case, it can be considered to replace the Category 5e cable.

The second possibility is the network adapter. If the network adapter is 100 Gigabits, the local connection can only be 100 Gigabits. In general, the cause of the network adapter is more likely!

It is the spring pattern caused by the network is not set correctly, and the methods to improve the network speed are: 1. First find the computer on the desktop of the computer or my computer icon. 2. Then right-click the computer or my computer icon, the drop-down menu of the right-click pops up, and we can find "Device Manager" in the menu.

3. Click "Device Manager", the window page of Device Manager will pop up, and we can find "Network Adapter" on the page. 4. Double-click "Network Adapter", and the network card model of our computer will appear. 5. Then double-click on the network card of our computer, and the property window page of our computer network card will pop up, and we can find "Advanced" in the menu at the top of the page.

6. Click "Advanced", you will enter the advanced settings page of the network card properties, and we can find "Speed and Duplex" in the property list on the left side of the page. 7. You only need to check "Speed & Duplex", and then set the value of "Speed & Duplex" to "Full Duplex", so that you can increase the local connection speed from 100M to 1G. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again!

We must first understand the process of network speed transmission: the optical modem is still a gigabit network, and the switch (often called a router in life) is also a gigabit, but there is one thing we must pay special attention to, that is, the wired network of the router, the WAN port and the LAN port must support Gigabit, otherwise after the switch is converted, it will be connected to the LAN port, and there will be a 100 Gigabit broadband phenomenon.

In addition to the LAN port output of the router may be 100 megabits, there is also the limitation of our computer itself, poor configuration or computer card, even if the network speed is good, it is not because the computer affects the network speed, but the computer itself has poor computing power. Therefore, the reason for the slowdown of the network speed is that the computer configuration also has a certain impact.

In addition, under normal circumstances, the transmission signal capability between the wireless router is stronger, much better than the signal ability of the notebook and the wireless router, so the direct transmission ability between the optical modem and the switch must be stronger than that of the switch and the computer, and the signal is better.

Finally, network transmission is a typical barrel principle, and the minimum bandwidth determines our overall networking bandwidth, so we must ensure that our network is smooth and efficient from all aspects.

How do you know for sure it's a Gigabit LAN?

Are you wired or wireless?

Have you tried the test of changing the Gigabit network card?

You can directly connect the computer to the optical modem to try it, if it is still 100 megabits, it means that it is a network card problem.
