What to do if the internet speed sometimes slows down, what to do if the internet speed becomes very

Hello, for your question, you can try the following operations to analyze:

Slow internet speeds. Is there any abnormality in the system? Convention, 10,000 anti-virus in advance.

Can I get on QQ but can't read the web? Open the local link property to reset the IP of the DNS

The network isn't optimized, or the bandwidth isn't enough? Try to optimize the network with Super Bunny, and this can be excluded from broadband above 2M.

Is the network cable connected correctly? The optical fiber is connected to the WAN port, and the network cable is connected to the LAN port.

Do you have a fixed IP? The common problem of routing is that the response will be slower when assigning multiple IPs, so you can set a fixed IP to try.

Someone is using P2P software to grab bandwidth? Install and turn on a firewall. This can be excluded by stand-alone users.

Has it been attacked? The attacked network will slow down, please install 360 Guardian to solve the problem.

Is the machine or router overheating? Sometimes, when the route is turned on for a long time, the data is blocked or the heating is too high, which affects the network speed.

Is the read and write efficiency of the storage device slow? Disk cleanup + defragmentation, or replace with a higher-speed storage device.

Is there a lot of network signal interference? Turn off the transmitter next to it and move the magnetic device away.

Poor network cable contact? Check whether the crystal head has dust accumulation and oxidation, and try to change the network cable or interface.

Have a problem with NIC settings? Try changing the NIC mode to 100m half-duplex, 100m full-duplex, fully automatic, and see which one is best.

Slow network card connection? Ping the gateway, if the response is slow, try to change the network card.

Network downtime or busy? Try again after a while. or contact the service provider (or administrator) to resolve the issue.

The specific problems are analyzed in detail. The correct way to measure the speed of the Internet is 1, the computer is directly connected to the cat (without passing through the switch router and other equipment in the middle) 2, to the official website of the corresponding operator**file test 3, right-click the link of the **file - save as (do not use **software) 4, close all other software that occupies bandwidth. If the network speed is not up to standard, call the customer service of the corresponding operator to report the fault.

1M broadband is generally about 100kbs, and 2m broadband is generally about 200kbs. I guess your measurement method is wrong. For example, you measure your internet speed while you ** a file.

The data must not be accurate. Or during peak hours at night, the network speed is also very slow.

I'll keep it simple.

It's time to close. It's time to delete it!

First of all, check whether there is a virus in your computer, if not, find someone from Netcom or Telecom business hall to help you check whether it is a problem with the line.

360 traffic monitoring to see if there are any other network connections.

Cause 1: The broadband line is aging or the modem (router) is damaged.

The second reason is that if the computer shares a network cable with other computers, the computer may be attacked by the ARP virus.

The third reason is that there is a certain program that secretly runs in the background and occupies a lot of bandwidth, such as viruses, Trojans, P2P software (Xunlei, QQ, Whirlwind, etc.).

Detailed solution:

1.First of all, check whether the network line is normal and whether the router or cat is damaged. It is recommended to find the customer service of the telecom operator to solve this part.

2.If it is ruled out that it is a line problem, and then check whether the computer is in the virus, it is recommended to use Kingsoft Guardian to kill the computer, because Kingsoft Guardian is different from other antivirus software, it can not only detect and kill Trojans. It is also possible to repair the damage to the system caused by Trojans.

3.If there is an ARP virus attack on the LAN, the Kingsoft Guardian ARP firewall will give an alarm, prompting an ARP attack on your computer by an IP computer, and then contact the network management to use Kingsoft Guardian to kill the attacking computer.

Clean up the system, reduce unnecessary programs, close unused Internet programs, and replace the machine if the computer is too old.

Clean up the garbage. Software that is not used. Plugins, Files**. Optimized acceleration,

Try it another and let Telecom come to your door to take a look, it may be that the router connector is aging.
