How to obtain the status information of the local connection, mainly the data of network traffic

Look at your network service, I mean to see if someone is stealing your broadband, or if you are using the same line as someone else, and you have to pay attention to the fact that your machine may have a virus sending information to the outside, well, or what software you have installed, such as vagaa, he will automatically send data outward, very bad rogue software.

Do you know why a ** thing, receives more packets than the previous one? The previous data is sent by your own computer, the main purpose is to show the connection of the network, generally send one, receive one (meaning), so as to prove that your network is connected, but when you ** something, your computer is dragging things back from Ethernet (that is, data), so, the number of data packets displayed behind you is significantly more than the previous packet, in this way, it depends on the size of your network traffic

Why did I say you can't get a good internet speed? The network speed of a network depends on its network data traffic, and the same 100 traffic, the network speed of 1m and the network speed of 100m are different (metaphor). When the amount of data packets behind you is too much, it causes network congestion, and the data packets sent by the computer to the outside cannot be sent, and the actual effect of the display is that the network is disconnected

Therefore, it is not the problem of the computer, it is the problem of your Internet speed, and the Internet speed of ordinary people is not very fast, and this situation will not exist in Internet cafes.

Seeing that your first problem is solved, I don't know if it's what I said.

Now let's talk about your second question.

Since the freeze occurs before the operating system is booted, and it works fully properly after repeated boots, there is a small chance of a virus that may be related to the motherboard and switching power supply.

In order to protect the stable and reliable operation of the microcomputer, after turning on the power supply, the power good signal line of the microcomputer power supply will send a microcomputer self-test start signal with an amplitude of 5V to the microcomputer motherboard when the delay is 5V and 12V ready, if the signal cannot be upgraded to 5V in time, the system will not start normally. Reset after the power good signal is normal to start normally. It is difficult to check under amateur conditions, so you can replace the switching power supply and give it a try.

If you are able to rule out the problem with the switching power supply, you can further check the rest of the main unit. It may be that the electrolytic capacitor or tantalum capacitor of a certain equipment leaks, and it needs to be charged for a certain period of time to slowly recover, and individual semiconductor chip failures are also possible, so you can only remove the board one by one to try, until only the graphics card has not been solved, after powering on, touch the capacitors and chips on the board with your hand to see if there is abnormal heating, if the capacitor or chip has abnormal heating phenomena, it should be replaced.

Wouldn't it be nice to use a P2P terminator?

To put it simply... Antivirus software has things to monitor traffic, so look for it yourself.

Don't forget to give points.

What you said is not the same thing as the traffic you use, this is a sign of network connection, its unit is KB, and the wireless network card is charged according to the traffic, this will be a text message prompt every day, it will not be wrong, and it is related to telecom operators.

Hello, the unit of computer traffic is generally "bytes", the unit is 'b', 1024b=1kb, 1024kb=1mb, 1024mb=1gb, convert the traffic (bytes) units accepted and sent by the computer into gb, calculate it (I use a network card, the speed is a little slow, only a dozen mb a day, and the traffic of 1gb can take a long time).

It's hard to say, it's a packet generated by a request sent by a computer when it accesses the Internet. And there is no exact size.

If you want to know how much traffic your machine is using, the next traffic monitoring software will do.

The unit of transmission and reception is bytes.

1KB = 2 bytes.

1mb=1024kb

1gb=1024mb

Honestly, it really can't help you!

Thoroughly inspect each crystal head, according to my experience, it is estimated that it is a problem with network cables and connectors.

You turn off both the router and the cat, and wait for two or three minutes to try it out.

If you're using it yourself, try getting your IP address and DNS address automatically.

Set your local connection to the metered network method:

1. Press win+r to open the run, enter regedit enter to open the registry;

2. The following locations:

hkey_local_machine\software\microsoft\windows nt\currentversion\networklist\defaultmediacost

3. Obtain the administrator privilege of the child defaultmediacost.

4. Find Ethernet on the right side, this item is the local connection (Ethernet), double-click, and modify its value to 2;

5. After restarting, you can set the local connection as a pay-by-traffic network.

Initial suspicion for ARP attack Enter cmd-and then arp -a to check if there is any abnormal IP-MAC installation of 360 ARP firewall because it can be solved.

LAN network attacks, sometimes IP conflicts, it can be killed with a P2P terminator and a 360ARP firewall

If it's a cyber attack, if it's a local area network, use an ARP firewall, if it's an external network, just use a firewall.

Let's talk about whether yours is a LAN or a single station.

Use 360 to check the startup items and close the ones you don't need.

The unit is Bitstream.

In computer networks or network operators, in general, the unit of broadband rate is expressed in bps (or b s); bps stands for bits per second, which means how many bits of information are transmitted per second, which is the abbreviation of bit per second. In the actual meaning of 1M bandwidth, it is 1 Mbps (it is megabits per second Mbps, not megabytes per second).

1b=8b 1b s=8b s (or 1bps=8bps)1kb=1024b 1kb s=1024b s1mb=1024kb 1mb s=1024kb s specification prompts judgment: b should mean byte (byte) and b should mean bit (bit) in the actual writing specification, but in the actual writing at ordinary times, some bit and byte are mixed as b, such as mb s and mb s are mixed as mb s, This leads people to make mistakes in actual calculations due to confusion of units.

The sending and receiving of the local link refers to the amount of information you send when you communicate with the remote server during network operations such as surfing the Internet or entering the Internet or referring to online games, QQ, etc., and the amount of information sent is generally smaller than the data received.

The smallest network data unit (generally common for tease) is B, then generally KB and MB, followed by GB, and finally TB when buying a large hard drive.

The smallest unit of measurement in the NIC is: "B" b S is how many B data is per second, and the data conversion algorithm is (1TB) = (1024GB).

1gb) =1024mb)

1mb) =1024kb)

1kb) =1024b )

That's not a lot of traffic. Could it be an ARP problem. Try it with a different network card.

It's not a matter of the local connection, what network cable do you tell them to check for line loss.
