Some users reflect, the ADSL high-speed broadband network is sometimes not as good as the original narrow-band MODEM (modem) online. So, what cause is caused by slowing the Internet speed? How to find and exclude it quickly?
1. There are too many protocols bound by the NIC.
The Internet is slow, and it is common in the LAN users because there are too many protocols bound by the NIC. If binds on the NIC
Many protocols, when the data passes the network card, the computer takes a lot of time to determine which protocol used to use which protocol is used to transfer. At this time, the user will feel slow. The solution is to let a web card run only the PPPoE protocol to connect ADSL, provide an external connection to the Internet, another network card Other protocols of the LAN, thus improve performance, so that the client Internet speed will improve.
2. ADSL equipment is cold.
When the ADSL equipment works, it is relatively large. It should be paid attention to heat dissipation. Many users put the ADSL equipment and routers, hubs, etc., and a variety of equipment works with heat, affecting the normal work of ADSL. If you just get online, it is 5 minutes or so, the speed is lowered, the download rate is like a narrow band 56kmodem. At this time, it is very hot with the hand to touch the equipment, change an ADSL device, speed up. Therefore, the equipment such as microcomputer, ADSL can not be placed in the same chamber, to disperse, there is a ventilation channel between the equipment, the microcomputer room is preferably constant, and the ambient temperature should be controlled at 10 ° C ~ 30 ° C. The relative humidity is maintained at 40% to 70%.
3. Access the internet interface error.
This is due to the Internet interface error caused by the Internet connection wizard of the IE, ENTERHET300 (virtual dialing software) is used by the local area network type virtual dial, and IE default uses ordinary dialing, IE when I first browse. Look for dial-up interfaces. If you can't find the dial, you can find a proxy server in the LAN, and finally find the interface 300 interface, so it will be very slow, just need to re-run a network connection wizard, select a local domain network, and cancel the automatic search proxy server Can be resolved.
4. The system does not support multitasking.
If the user's computer just meets the minimum configuration, the system cannot support a number of tasks such as simultaneous browsing web, download software, listening to music. A variety of tasks will feel slow in the same time. Therefore, the work task is generally not more than two items.
5. The TCP / IP protocol is not bound.
Unbound TCP (Transmission Control Protocol) / IP (International Agreement), more than the NIC driver is not installed, network card quality has problems, PCI (bus standard) slot is not good. You should first remove the network card in the device manager, and then install the driver after reboot;
If it is not good, change the network card to a PCI slot, still do not change a network card.
6. The quality of the telephone line is poor.
ADSL technology has high quality requirements. The currently used ADSL is a radsl (ie, rate adaptive ADSL). If the telephone line between the telephone bureau to the user is absentually interfered with external factors in a certain period of time, RADSL will be based on the line The advantages and disadvantage of the quality and the distance of transmission distance are dynamically adjusted to the user's access speed. If access is a foreign site, the speed will be affected by factors such as export bandwidth and the other party's site line, equipment configuration, and need all network coordination and solving. The line problem is mainly: because the construction standard is not followed, the remaining quality hidden dangers, such as the no added plastic casing causes the mouse to bite the route; the distribution frame or other materials are poorly exposed due to quality problems; the user is in renovation Applying indoor wire damage, etc.
7. The software is not reset.
After the user installs the ADSL broadband, the Internet condition has changed, but the corresponding tool software is not reset, it is one of the reasons why the speed is slow. If the communication software QQ, it needs to be set to it. From the QQ panel, select the System Parameters command, click the Network Settings tab, change the original "Dial-up Internet" to "LAN Access Internet". 8. Microcomputer hardware software problem.
The hardware failure is mainly manifested in the user network card damage or not properly installed; the user microcomputer motherboard and NIC are not compatible; the microcomputer grade is too low, and the memory is less slower. Such as hardware configuration Celero 600 / 64MB memory, WindowsXP operating system, can cause the microcomputer to run is quite slow, and the Internet speed is not high. Software failure is mainly due to user not understanding computer knowledge, causing the operating system error or dialing software, can't get online; users do not have correct operation, causing dial-up software illegally shut down, causing software errors; users browse some web pages There is a problem in the system. If you accidentally delete the backup dialing software; the user's microcomputer has problems, and after reinstalling the system, no dialing software is installed. These issues can be excluded as long as the dial-up software is reinstalled.
