Ask questions about the type of network and the speed of the network

Let me briefly say it: you must know that the network speed of optical fiber Internet access and ADSL Internet access is different, generally speaking, the fiber speed is relatively fast, suitable for Internet cafes, large and medium-sized enterprises, and the transmission signal speed of optical fiber can reach between 500 and 700k s. (ADSL) internet speed is average.

It is a high-speed access to IP obtained through ** line, the speed is generally 90 110K s is suitable for home Internet access, and the school sets up a LAN Because the speed of light is faster than the speed of electricity, fiber optic Internet access will be much faster than ADSL Internet access, from your description, your home's broadband is telecom, but it is the address of Maoming, Guangdong, and your cat's IP address is not very correct, the back value should be "125" is not 52, and from the speed of your **, your home is broadband? In this way, I suggest that you make a system for the computer (remember to change the cat's pi address) and then try it, if it doesn't work, it's a broadband problem, and call for repair to telecom customer service, **is -10000 to manual service broadband repair.

1. "Candidate DNS server."

This is the DNS of Guangdong Maoming Telecom

But you are in Yulin, how do you use Maoming's DNS? It is recommended that you change it to your Yulin Telecom's DNS, what I found is, in fact, you can call**Consult 1w number mm to ask her for a DNS address.

2. "This computer doesn't use that broadband connection, mine is directly on, and I don't need to turn on the broadband connection like my friend."

This is cell broadband.

That is, you are using cell broadband of telecommunications.

3. "There is also a special situation: it is very strange that my family can open the web page for a while, but it can't be opened for a while, and the frequency is once every dozens of minutes."

QQ can be uploaded again when the web page is opened, but as soon as it goes up, it will be stuck for a few minutes, and then it can be moved.

When you can't open the web page, you can also log in to the QQ game lobby and play games.

There are two reasons: First, you are using Maoming Telecom's DNS, of course, the domain name resolution is not as fast as the local one, and changing back to Yulin Telecom's DNS will be greatly improved.

Second, the nature of community broadband sharing, so if there are many people in your community at the same time, the network will be stuck, or some people can't get on at all.

You're the fiber of the cell.

Summary. Based on different speeds, there are 10Mbps, 100Mbps, 10 100Mbps adaptive cards, 1000Mbps, 10G, 25G and even higher speed network cards. 10Mbps, 100Mbps, and 10 100Mbps adaptive NICs are suitable for small LAN, home, or office.

A 1000Mbps network card provides higher bandwidth for Fast Ethernet.

What are the differences in network transfer rates between different types of NICs?

Based on different speeds, there are 10Mbps, 100Mbps, 10 100Mbps adaptive cards, 1000Mbps, 10G, 25G and even higher speed network cards. 10Mbps, 100Mbps, and 10 100Mbps adaptive NICs are suitable for small LAN, home, or office. A 1000Mbps network card provides higher bandwidth for Fast Ethernet.

Can you add, I don't quite understand it.

Network card: 10Mbps network card is mainly an old-fashioned low-grade network card. It had a bandwidth limit of 10Mbps, which was common with ISA bus-type network cards at the time. At present, some PCI bus interface types of network cards are 10Mbps network cards, but this type of network card is not the mainstream at present.

This wide network card is only suitable for some small LAN or family needs, and the medium-sized network is generally not selected, but it is relatively cheap, generally only a few dozen dollars. NIC NIC This is a NIC with adaptive bandwidth of 10Mbps and 100Mbps, and it is also the most popular type of NIC at present, mainly because it can automatically adapt to the network requirements of two different bandwidths and protect the user's network investment. It can be connected with the old 10Mbps network equipment or applied to the newer 100Mbps network equipment, so it has been widely recognized by users.

The NIC of this bandwidth will automatically select the appropriate bandwidth based on the usage environment. For example, if you are connected to an old 10Mbps device, its bandwidth is 10Mbps, but if you are connected to a 100Mbps network device, its bandwidth is 100Mbps, which can be configured simply (or without). In other words, it can be compatible with old network equipment of 10Mbps and new network equipment of 100Mbps.

Ethernet Gigabit Ethernet is a high-speed LAN technology that can provide 1Gbps of bandwidth over copper wires. The corresponding network card is a gigabit network card, and again, the bandwidth of this network card can reach 1Gbps. There are also two main network interfaces of Gigabit network cards, one is the common twisted pair RJ-45 interface, and the other is the multi-mode SC standard optical fiber interface.

One trillion network speed, under normal circumstances, ** speed is about 100k. Sometimes, it is normal to be slower, just like a car on the road, although the speed limit is 60 kilometers, but it can't drive fast in traffic jams.

If the network speed is very slow, resulting in a game drop and points will be deducted, then you need to analyze the reason:

1. Line problems. Such as the first line aging, rust, poor contact;

2. Equipment problems. For example, the network card is not properly installed, or the network stop is damaged;

3. There is a viral infection, such as ARP virus.

2. Carefully inspect the network and ** line to see if there is rust, if there is rust, replace it with a new one.

3. Uninstall the network card and reinstall the driver. Or force the rate of the network card to 10M, which can improve the stability of the transmission (this trick is quite smart!). ）。

4. If it doesn't work according to the above 3 points, it is recommended to try a different network card.

Hope the above points can be helpful to you.
