My home internet speed could have been more than 200k, but recently it has dropped to more than 90k,

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

Unstable internet speeds.

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

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.

PPS accelerators occupy bandwidth. Either pull one yourself or limit his internet speed.

If the broadband speed slows down suddenly, if it's a problem with your carrier, you can contact your carrier to solve it. If the broadband network cable connection is a problem, check the connection interfaces. There is a problem with the computer's own settings, and the solution is as follows:

1. Click to enter the "Control Panel" option of the computer;

2. On the "Control Panel" page, click on the "Network and Sharing Center" option;

3. On the "Network and Sharing Center" page, click on the "Change Adapter Settings" option;

4. On the "Change Adapter Settings" page, click "Local Connection", right-click and select the "Properties" option;

5. On the "Properties" page, click the "Configuration" option and select the "Advanced" option;

6. Find "Duplex Mode", select "100Mbps Full Duplex" on the right, and then click the "OK" option below to automatically optimize the local connection speed.

This situation is mostly the problem of the operator! For example, when you first installed the community, there were only 6 users, and the operator's main optical fiber was 20m. At this time, your network is naturally relatively fast.

But after that, the operator added 20 more users, so there were 26 users in total, but the main fiber was the same as 20M, and of course you only had a speed of tens of k!

It may be that the C drive does not have enough space, or the computer is poisoned.

Is it connected to the router?

Or maybe it's too far away from the AC.

You can also try to change the fiber optic cable.

Are you community broadband?

If yes, then that's normal!

Because cell broadband is shared bandwidth! The more people there are, the slower!

There are many reasons for slow network speed, there are too many garbage cleanups, too many applications are opened, or they are poisoned, you check it step by step,

How is your home network connected? What is the bandwidth? Is it ADSL, Cell LAN, or Fiber Exclusive?

If it is an ADSL access, it may be that the cell node is saturated. Because what you said is too vague to judge!

Hello, Anhui Telecom will answer for you.

Hopefully, the following will be helpful to you.

1. The reasons for the slow network speed are: unstable power supply voltage, static electricity of the computer network card chassis, computer poisoning, system software failure, etc., it is recommended that you give priority to self-inspection or ask computer maintenance personnel to assist you in troubleshooting.

2. You can first check whether the modem and splitter hardware are faulty, whether the splitter connection is correct, whether the modem is compatible with the network card, and it is recommended that you replace other modems to observe the usage.

3. If the disconnection is related to the application server while playing the game, it is recommended that you contact the game provider for verification.

4. If the above operations are invalid, dial 10000 and select the 4 key to report broadband faults;

If your question is solved, please give a "satisfactory answer", and if you still have questions, please continue to ask. Have a nice day, thank you!
