Some users have reported that during use, ADSL high-speed broadband network is sometimes not as fast as the original narrowband MODEM (modem) network speed. So, what are the main reasons for slow Internet access? How to quickly find and exclude?
1. There are too many protocols for network card binding.
The Internet speed is slow and is very common among LAN users because there are too many protocols bound to the network card. If there are many protocols bound to the network card, when the data passes through the network card, the computer will spend a lot of time determining which protocol to use to transmit the data. At this time, the user will feel that the Internet is slow. The solution is: let one network card only run the PPPOE protocol to connect to ADSL, provide external connections to the Internet, and the other network card runs other protocols of the LAN, so that each performs its own duties to improve performance, so that the speed of the client's Internet access will be improved.
Poor heat dissipation of the equipment.
ADSL equipment generates a lot of heat when working, so you should pay attention to heat dissipation in normal times. Many users place ADSL equipment, routers, hubs, etc. in the same cabinet. When various equipment work, it will affect the normal operation of ADSL. If it was normal when I first went online, the Internet speed dropped in about 5 minutes, and the download speed was the same as the narrowband 56kMODEM. At this time, it was very hot to touch the device with your hands. If you change to an ADSL device, the speed will increase. Therefore, microcomputer, ADSL and other equipment should not be placed in the same cabinet, but should be placed in a scattered manner, and ventilation and heat dissipation channels are left between the equipment. It is best to have a constant temperature in the microcomputer room. The general ambient temperature should be controlled at 10℃~30℃. It is better to maintain the relative humidity between 40% and 70%.
3. Access to the Internet interface error.
This is caused by the error of the access interface specified by the Internet connection wizard of Windows (window software) to IE. Enterhet300 (virtual dialing software) uses LAN-type virtual dialing, while IE uses normal dialing by default. When browsing, IE first looks for the dialing interface. After you can't find the dial-up, you can find whether there is a proxy server in the LAN, and finally you will find the Internet300 interface, so it will be very slow. You just need to rerun the Internet (Internet) connection wizard, select the LAN method, and cancel the automatic search for the proxy server to solve the problem.
4. The system does not support multitasking.
If the user's computer just meets the minimum configuration, the system cannot support multiple tasks such as browsing web pages, downloading software, listening to music at the same time. When working with multiple tasks at the same time, you will feel slow to access the Internet. Therefore, it is better not to have more than two work tasks at the same time.
5. The TCP/IP protocol is not bound.
The TCP (transmission control protocol)/IP (international protocol) is not bound, mostly because the network card driver is not installed properly, the network card quality is problematic, and the PCI (bus standard) slot is not good. You should first delete the network card driver in the device manager and install the driver after restarting; if it is not good, change the network card to a PCI slot. If it is not good, change it to another network card.
6. The quality of the telephone line is poor.
ADSL technology has high requirements for the quality of telephone lines. The ADSL currently used is a type of RADSL (i.e., rate adaptive ADSL). If the telephone line between the telephone office and the user is disturbed by external factors at a certain period of time, RADSL will dynamically adjust the user's access speed according to the quality of the line and the distance of the transmission distance. If you are visiting a foreign site, the speed will be affected by factors such as the export bandwidth, the other site's routes and equipment configuration, and the entire network needs to be coordinated and cooperated to solve the problem. The main line problems are: because the construction standards are not followed during construction, which leaves hidden quality hazards, such as the failure to add plastic sleeves to cause the mouse to bite the line; the patchwork frame or other materials have poor contact with the jumper due to quality problems; the indoor wires that users secretly apply during decoration are damaged, etc.
7. The software has not been reset.
After the user installed ADSL broadband, the Internet access conditions have changed, but the corresponding tool software has not been reset, which is also one of the reasons for the slow speed. For example, the communication software QQ needs to be set up. Select the "System Parameters" command from the QQ panel, click the "Network Settings" tab, and change the original "Dial-up Internet access" to "LAN Internet access".
8. Microcomputer hardware and software problems.
Hardware failures are mainly manifested in the damage to the user's network card or not properly installed; the user's microcomputer motherboard and network card are incompatible; the user's microcomputer grade is too low and the memory is low, resulting in slow operation speed. If the hardware is configured with Celeron 600/64MB of memory and the WINDOWSXP operating system, it will cause the microcomputer to run very slowly and the Internet speed cannot be high. Software failure is mainly due to the user's lack of understanding of computer knowledge and misoperation during use, resulting in an error in the operating system or a damage to the dialing software and unable to access the Internet; the user fails to operate correctly, causing the dialing software to be illegally closed, resulting in software errors; after the user browses some web pages, the system has problems and accidentally deletes the backup dialing software when processing; when the user has problems with the user's microcomputer, the dialing software is not installed after reinstalling the system. These problems can be troubleshooted by reinstalling the dialing software.
