Anonymous users2024-02-05The 100m you see is displayed on the screen, right? That's not real speed.
That is to say, no matter how fast it is, when it is connected to the desktop, it is generally displayed at 10m, 100m or 1000m
There are hardware problems, such as the cable you use is not very good (the quality of the wire body and the quality of the connector); The line is too long, there is strong magnetic interference near the line, etc., etc.
My configuration is Centrino memory 14" XGA TFT built-in*** ROM. 40GB hard drive. It's also adsl online.
However, the speed of Internet access has nothing to do with the optical drive or monitor.

Anonymous users2024-02-04Problems with network cables. Twisted pair wires are tightly wound together by four pairs of wires strictly and reasonably to reduce the effects of background noise. There are great hidden dangers in the network cable that is not made according to the correct standard, and some of them are used normally for a period of time, but after a period of time, the performance decreases and the network speed slows down.
Loop issues. Generally, this situation rarely occurs when the network is small, the number of nodes involved is small, and the structure is not complex. However, in some more complex networks, it is easy to form loops, and data packets will be continuously sent and verified data, which will affect the overall network speed, and it is difficult to find.
In order to avoid this from happening, it is required to develop good habits when wiring. Broadcast storms. As the main means of discovering unknown devices, broadcasting plays a very important role in the network.
However, as the number of computers in the network increases, the number of broadcast packets increases dramatically. When the number of broadcast packets reaches 30, the network transmission efficiency will be significantly reduced. When the network card or network equipment is damaged, the broadcast packet will be sent non-stop, resulting in a broadcast storm and paralyzing network communication.
Port bottleneck. In fact, the router's WAN port, LAN port, and server network card may become network bottlenecks. Network administrators can use network management software to view the data traffic of routers, switches, and server ports during peak network usage hours to determine the location of network bottlenecks and try to increase their bandwidth.
Worms. Worms are increasingly affecting network speeds. This virus causes the infected user to send emails as long as they are connected to the Internet, and the virus selects random documents from the user's computer to attach them to a random address in the user's address book for email.
Spam emails are sent out in queues, and some are piled up on servers by bounces in batches. As a result, some backbone Internet networks are obviously congested, and the local area network is nearly paralyzed. Therefore, administrators should always pay attention to various new virus notices and understand the characteristics of various viruses. Upgrade the anti-virus software used and install system patches in a timely manner; At the same time, unnecessary services are offloaded and unnecessary ports are closed to improve the security and reliability of the system.

Anonymous users2024-02-03Landlord: Can you guarantee that your machine is not poisonous, but can you guarantee that the other machine is not poisonous, and there is a kind of virus (which I don't know) that seems to be taking up bandwidth.
If you can guarantee that 2 machines are virus-free, there are only 3 possibilities:
2 There is a problem with the broadband connection line (you can call the local telecom** for repair).
3 Is your splitter (router or switch) working? Try a different splitter.
Basically, it solves the problem.

Anonymous users2024-02-02Maybe it's the computer, or maybe the interface is a little bit loose.
1 Check to see if the LON light on the back of your case is on. >>>More
Network authentication refers to the process of authentication when using a network service. Typically, network authentication is done by entering a username and password. The specific network authentication method will vary depending on the network service provider. >>>More
Well, I'm engaged in the network, let me tell you carefully, first of all, the computer and the computer should interact, and the server should interact, similar to an agreed language, to both sides agreed, this is the protocol in the network, what is the network, first of all, physically, that is, the network cable that connects various computer equipment, and various network equipment (switches and routers, etc.), the organization of the network is actually very complex, because the number of equipment is growing too rapidly, In fact, the function of the computer's network card is to process the information you want to send into a digital bit stream in accordance with the ios7 layer protocol, and then reverse convert it after someone else's computer gets the data. Said data packets, data frames, the landlord may not be able to recognize clearly, The network is connected to the computer and the computer, to achieve information sharing and interaction, and so on, to make the world so exciting, information ** so fast, By the way, there are a lot of network interfaces, Half of them are also a lot, Generally refers to the physical port, It's the interface on the physical level.。。。 If there is anything else the landlord doesn't understand, you can ask me.
Zhicheng broadband network TV.
I tell you, the ADSL of Telecom is the best. I used to use video broadband this year because of your problem, and I regret it very much!! I can't even open it!!
