My desktop computer internet speed suddenly slowed down What s going on Troubleshoot network issues

Optimizing the system can be solved. The following is an optimization method written by a group of netizens, which is not bad, you can refer to it.

One. Systemic aspects.

It is normal for a system to slow down and become stuck after a period of use, and we can solve this problem manually by ourselves:

1: Kill the virus first, the system poisoning will affect the running speed of the computer. Antivirus software (Rising or Card Bar) to disinfect the system Use 360 Security Guard to clean and remove some malicious plug-ins or rogue software in the system and IE.

2: Then close some unnecessary program startup and service: Start - Run - Enter msconfig - Start Except for ctfmon and antivirus programs, everything else is turned off.

If it's still very stuck, you can turn off the startup of the antivirus software, because the general antivirus software will also affect the running speed of the computer, but it is best not to mess with the unclear **and** regular antivirus.

3: Clean up the system junk of the C drive It is best not to put too many files on the C drive.

Move some files or programs other than WindoIWS to another disk Delete the backup file of the upgrade patch similar to ($ntuninstallkb 834707$ hidden attribute) under C: Windows.

Turn off System Restore My Computer Right-Click Properties - System Restore - Turn off System Restore on all drives.

Turn off hibernation: Desktop right-click properties - Screensaver - Power - Hibernate - "Enable Hibernation" and remove the checkmark OK.

Hit my computer - right-click properties - disk cleanup - tools - defragment.

4: Virtual memory My computer right-click properties - advanced - performance - settings - advanced - virtual memory change - set the virtual memory of each disk to "custom size" to enter the initial size and maximum value and then click to set (the initial size is according to the recommended number prompted below, the maximum value is set to 2 times the initial size.)

5 Optimize the system Recommendations:

2。Create a folder in a non-system disk and extract the compressed files from it

Click the optimization master icon--- "System Information Detection" - System Information Overview" content appears--- click "Save Information", make backups--- click "Automatic Optimization", and exit when it is over

Try your computer, if it's a little fast that you are not used to, if you are satisfied, please

Click on the Optimizer icon--- click on "System Cleanup and Maintenance" -- click on "Registration Information Cleanup" -- click on "Backup" (important) -- select the scan object (you can also use the default settings) -- click on "Scan" -- Suggest) Click on "Delete All".

Click the Optimizer icon--- click "System Cleanup and Maintenance" -- click "Junk File Cleanup" -- click "Scan" -- click "Delete All", and exit when it is over.

Take a look at "My Computer" and see that your disk space is a lot larger.

There is extra time to defragment the disk

There are a few common reasons why your broadband network is slow:

1. If the bandwidth of the ** server is narrow or the server is busy, you can try to change the time period to access or access other** to determine whether this problem is caused;

2. Computer reasons such as low computer configuration or weak system processing power;

4. The use of routers to share the Internet leads to slow network speed;

5. If the modem device is unstable, it is recommended that you replace the modem device for testing;

6. Line reasons (such as long line, noisy line, poor quality of the entrance line, change of the user-side line, etc.).

If this is not the case, you can contact the local customer service for feedback.

Just reinstall the system.

The solution to the normal network but the computer network speed is very slow:

1. If the performance of the PC terminal does not meet the requirements, if the performance of the user's computer terminal network card itself or the system memory is insufficient, it will cause the user to fail to reach the agreed rate during the speed test. In actual use, only when the rate supported by the computer network card is greater than the access broadband bandwidth, can the contract rate be guaranteed.

2. DNS domain name configuration error, this error usually occurs after the user changes broadband operators, and the DNS used before is still set to the DNS of the previous operator, resulting in customers accessing network resources and being wrongly scheduled to outside the network, which in turn affects the network speed.

3. The performance of the wireless router is not up to standard, and among the reasons of the client, user complaints caused by router failure or setting problems account for about 30% of the network quality complaints. The user-purchased router brand, quality, and quality are uneven, and the failure rate is different.

Note: A typical scenario for judging companions is that if the user feels that the web page opens slowly when it is busy at night, which is very different from the perception during the day, it is likely to be a problem with the access network.

Due to the large number of users in the community and the large number of users accessing the Internet at the same time during the busy period, the sudden increase in service traffic leads to congestion in the uplink of aggregation devices, which affects the Internet perception of users in the entire community.

Generally, maintenance personnel are required to account for the community according to the number of accounts, contracted bandwidth, and the number of users in the community. The access bandwidth is re-calculated and the emergency capacity expansion is implemented, so that the services can be used normally.

What to do if the computer network speed is too slow.

If you are surfing the Internet through a router, you can restart the router and then refresh the web page. If you are directly online, it is recommended to restart the computer.
