This situation is usually caused by poor network signal quality or computer wireless network card driver problems. Network signal quality: The quality of the network connected to your laptop and mobile phone is not necessarily the same.
Reason 1: Your broadband line is aging, or the router is damaged. Reason 2: If your computer shares a network cable with other computers, your computer may be attacked by the arp virus. Reason 3: There is a certain A program secretly runs in the background and takes up a lot of bandwidth, such as virus Trojans, p2p software (Thunder QQ Tornado, etc.).
The signal of the wireless router is poor, causing the computer to be unable to search the wireless network. The wireless router is faulty or the wireless router settings are not normal. Solution: It is recommended to change a wireless router, but you can also try to restore the router to factory settings and reset the router. Try it.
The reason why the wireless network speed is very slow: Multiple devices are connected to the wireless network, causing the wireless router to activate the automatic speed limit function; the slow speed of the broadband connection itself causes the slow speed of the wireless network.
Solution to the extremely slow computer connection to WIFI: It may be a network problem with the computer device. You can try using other devices to connect to WiFi.
You can first reset the WiFi router to the factory state to eliminate the problem. If the fault still cannot be solved, it is recommended to replace the WiFi router; (8) It is recommended to consult the broadband operator to check the network bandwidth line and modem to see if there is a hardware failure. (It should also be noted that the bandwidth quality of network bandwidth operators in individual areas can sometimes be severely reduced).
Regularly, clean the dust in the computer. After shutting down, open the case and blow it with a hair dryer. 2. Use 360 Defender, Kingsoft Defender and other tools regularly to clean up system junk and temporary files (ie cache) generated by surfing the Internet, and to detect and kill malware. 3. The computer configuration is poor. Try to set the virtual memory as large as possible.
1. Turn off other network devices: If other devices are using the network at the same time, the network bandwidth may be occupied, causing the computer's network speed to slow down. slow. You can try turning off the network connections of other devices to see if that improves the quality of the network connection.
2. Check the number of devices connected to the wireless network and remove unnecessary device connections; use third-party computer management software on your laptop to test the speed of the broadband connection. If the network speed is inconsistent with the normal network speed, you can Call the operator's customer service number and ask for a solution.
3. Solution to the extremely slow WiFi connection speed of the computer: It may be a network problem with the computer device. You can try using other devices to connect to WiFi.
1. Solution to the extremely slow Wi-Fi connection speed of the computer: It may be a network problem with the computer device. You can try using other devices to connect to WiFi.
2. Regularly clean the dust in the computer. After shutting down, open the case and blow it with a hair dryer. 2. Use tools such as 360 Defender and Kingsoft Defender frequently to clean up system junk and temporary files (ie cache) generated by surfing the Internet, and to detect and kill malware. 3. The computer configuration is poor. Try to set the virtual memory as large as possible.
3. Keep the wireless router away from electromagnetic devices. Shorten the distance between network equipment and wireless routers, reduce the possibility of signal attenuation and interference, and add wireless relay amplification to expand WiFi signal coverage.
4. 1. Check the programs that occupy high network resources. When the network is stuck, use the key combination to open it and check the usage in .
1. Turn off other network devices: If other devices are using the network at the same time, it may occupy the network bandwidth and reduce the computer’s network speed. Slow down. You can try turning off the network connections of other devices to see if that improves the quality of the network connection.
2. Solution to the extremely slow WiFi connection speed of the computer: It may be a network problem with the computer device. You can try using other devices to connect to WiFi.
3. Finally, restart the computer to make the settings take effect. After restarting, the problem will be solved. It is rare that the computer will easily disconnect or be slow when connecting to WiFi.
The signal of the wireless router is not good, causing the computer to be unable to search for wireless networks. The wireless router is faulty or the wireless router settings are not normal. Solution: It is recommended to change a wireless router, but you can also try to restore the router to factory settings and reset the router. Try it.
The quality problem of wireless network card, inferior network card can easily cause network disconnection, slow network speed and a series of problems; the transmission distance problem, the transmission speed and distance of wireless signal are directly related to the intermediate isolation, the farther the distance , the more obstacles in the middle, the weaker the received signal and the slower the network speed.
Reasons related to the network environment Problems caused by operator line maintenance or network distribution Poor network cable contact or switch hardware problems Poor network cable contact or switch hardware problems will cause the network speed to slow down.
The above is the detailed content of The laptop is extremely slow when connected to wifi (the laptop is extremely slow when connected to wifi). For more information, please follow other related articles on the PHP Chinese website!
