Recently, the Internet has been very stuck and the Internet is suddenly very stuck

It is recommended that you do this, DHCP can be turned off, DHCP is really convenient to use, you must know that you can't have both fish and bear's paws, it is best to do static so that it is easy for you to manage.

Also, you have an ARP attack problem on your intranet, I don't know if you have done two-way binding or something.

Or install an ARP firewall or something. In addition, other attacks on the intranet, such as syndemo attacks, ghost shadows, skulls, and other DDoS attacks, will cause network instability, disconnection, slow card and other network problems.

Only the immune network can solve such an intranet problem, it is highly recommended that LZ use the Xinxiang immune wall router, only upgrading the network to become an immune network is the guarantee of the stability of your network.

There is an ARP attack, which will naturally be very stuck.

ARP attack is to achieve ARP spoofing by forging IP addresses and MAC addresses, which can generate a large amount of ARP traffic in the network to block the network, and the attacker can change the IP-MAC entry in the ARP cache of the target host as long as the attacker continuously sends out forged ARP response packets, causing network interruption or man-in-the-middle attacks.

It is recommended to install an ARP firewall.

In the case that the computer, the cat, and the line are normal, the size of the network speed depends on the following aspects:

1.The bandwidth of the route you use to access the Internet. The trillions that people often talk about refer to it.

2.The configuration of your computer or the quality of your computer's operating system. Generally, the configuration of the computer does not affect the network speed, if the configuration is too low, too many programs or software will be affected.

3.The rate at which your data port allows. Some may limit the port rate in order for everyone to be in a timely manner. At this time, no matter how large your bandwidth and high computer configuration are, it is useless.

5.The number of users connected to the network by local nodes means that everyone is slow when they are using the network, and fast when there are few people. Generally slower from late to o'clock.

You have a lot of packet loss in this case, you can ping -t to verify it, the possible reason:

1. Physical failure.

Intermediate connection lines, optical fiber connection problems, jumpers are not aligned with the equipment interface, twisted pair and RJ-45 connectors have problems, etc., in addition, the communication line is subject to random noise or sudden noise caused by datagram errors, radio frequency signal interference and signal attenuation, etc. may cause the loss of data packets.

2. Equipment failure.

For example, the network card is damaged, a port of the switch has a physical fault, the electrical port of the optical transceiver does not match the interface of the network device, or the duplex mode of the interface of the device at both ends.

3. Network congestion.

There are many reasons for the increase in packet loss caused by network congestion, mainly due to the large occupation of router resources.

I think I can give it to Hazi!

In the hot summer, the temperature is very high, the temperature of my chip is above 40 degrees, the temperature of the hard disk is higher than 45 degrees, and the temperature of the network card is more than 80 degrees; Can you work in such an environment? You still have a fan or an air conditioner or something, do you mind my business? Our Equipment (Device means:

Cats, routers, network switches, Hubble, computers, etc.) too, feel hot and can't work for you anymore; You can't go to the Internet, you look for masters in the north and south, don't cool me down, you can't find anyone (or replace cats, routers, etc.), because our brothers have the same temper, if you don't cool us down, we will strike!

You may wish to take a look at the following methods, and use measures that you feel are acceptable to reduce the temperature of my (equipment) working environment, and I promise: continue to serve you.

A: Users who often surf the Internet for up to half a year should open the shell of the device after the power is off and clean up the dust inside the device.

b: Place the equipment in a safe place for people, open the lid of the equipment, use air convection to strengthen contact with the air, and naturally dissipate heat;

c: Install a micro fan to the equipment to increase the convection of air and force heat dissipation;

D: If you are doing IT, I suggest that you install a heat sink on the heating part of the device after disconnecting the power supply.

e: After the equipment is disconnected from the power supply, use a 3mm drill bit to drill many holes up and down the equipment to strengthen the air convection flow and improve the heat dissipation conditions;

f: To ventilate and dry the equipment, it is best to make an insulated heat dissipation bracket (there are also notebooks on the market) to support the equipment for natural heat dissipation;

H: Let the adsl cat sync first: power off the cat and restart it.

i: The software settings are reasonable, so that 3 do not install: do not install informal software, do not install P2P (occupy resources) software, and do not install commonly used software. Turn off all unnecessary internet connections, such as Thunderbolt.

BT donkeys, etc.;

j: Optimize the network.

Personally, I recommend using some gadgets.

For example, Super Bunny, Optimizer or 360, etc.

K: The computer should have at least one effective and genuine anti-virus software installed, and the firewall should be set appropriately (not too much, too high).

l: NIC problem: The NIC bandwidth is appropriate and the operation is stable.

As long as you take care of our brothers (routers, cats, Hubble, network switches and their computers), our brothers promise to truly do: "You respect me, I respect you" for your faithful service. Otherwise, ride a donkey and read the record book--- let's see!

Thank you for my answer!

Thank you: friend!

Let's see if someone stole your **. There is a tool in 360 to prevent the net. Check it out. If no one steals your network, then call Telecom to ask if it's a network problem.

That is, there was no 4m at that time. It's like tap water for everybody. Low water pressure is a reason.
