Teach you how to find and troubleshoot ADSL slowing down

The

 1. Network adapter is bound too many protocols.

Slow Internet access is common among local area network users because the network adapter is bound too many protocols. If a lot of protocols are bound on the network card, when the data passes through the network card, the computer spends a lot of time to determine which protocol the data uses to transmit, then the user will feel the Internet is slow. The solution is: let a network card only run PPPoE protocol to connect ADSL, provide the external connection of the Internet, another network card to run the other LAN protocol, thus Kothing improve performance, so that the client Internet speed will improve.

2.ADSL device does not have heat dissipation.

ADSL equipment work when the calorific value is relatively large, usually pay attention to heat dissipation, many users of ADSL equipment and routers, hubs, etc. placed in a cabinet, a variety of equipment work a piece of heat dissipation, the normal work of ADSL has an impact. If the Internet is normal, 5 minutes or so, speed down, download speed and narrowband 56kMODEM, the same time with the hand touch equipment is very hot, for an ADSL equipment, speed on the up. Therefore, the computer, ADSL and other equipment can not be placed in the same cabinet, to spread out, the equipment between the ventilation and cooling channels, the best computer room to achieve a constant temperature, the general ambient temperatures should be controlled in 10℃~30℃. Relative humidity remains in 40%~70% as well.

3. Access to Internet interface error.

This is because the Internet Connection Wizard for Windows (Windows software) is causing an error to Internet interface specified by IE, Enterhet300 (virtual dial-up software) uses the LAN type virtual dialing, and IE defaults to using normal dialing , ie first look for the Dial-up interface when browsing. If you can't find the dial-up, you can find a local area network there is no proxy server, the last will find Enternet300 this interface, so it will be very slow, only need to rerun the Internet (Internet) Connection Wizard, select the LAN mode, and cancel the automatic search proxy server can be resolved.

4. Multiple tasks are not supported by the system.

If the user's computer just meets the minimum configuration, the system cannot support multiple tasks such as browsing the web, downloading software, listening to music, and so on. A variety of tasks at the same time you can feel the Internet slow. Therefore, at the same time the task is generally not more than two items as well.

5. The TCP/IP protocol is not bound.

Unbound TCP (Transmission Control Protocol)/IP (International protocol), multiple NIC drivesMoving program is not installed, Nic quality problems, PCI (bus standard) slot is not good. The Device Manager should be the first driver to remove the network card, reboot after the installation of the driver, if not good, to change the NIC to a PCI slot, still bad can be replaced by a network card.

6. The telephone line is of inferior quality.

ADSL technology for the quality of the telephone line is higher, the current use of ADSL is a RADSL (that is, the rate of adaptive ADSL), if the telephone line to the user between the phone lines in a certain period of time by external factors interference, RADSL will dynamically adjust the user's access speed according to the quality of the line and the distance of transmission. If the visit is a foreign site, the speed will be export bandwidth and the other side of the site line, equipment configuration and other factors, the need to coordinate the whole network to solve. The main line problems are: Because the construction did not follow the construction standards, leaving behind the quality of the hidden trouble, such as no plastic casing caused by the mouse bite off the line, wiring racks or other materials due to quality problems, resulting in the jumper contact bad, the user in the decoration of the indoor line damaged.

7. The software is not reset.

Users install ADSL broadband, the internet conditions have changed, the corresponding tool software has not been reset, but also caused by the slow speed of one of the reasons. such as communication software QQ, you need to make some settings. Select the "System Parameters" command from the QQ panel and click on the "Network Settings" tab to change the original "dial-up Internet" to "LAN access Internet".
