Several users have, ADSL high-speed broadband network in use, sometimes not as good as the original narrow-band MODEM (modem) Internet speed. So, Internet is slow mainly what causes? How to quickly find and remove it?
1. NIC binding agreement too.
Slow access, the LAN users are common, because too many card agreements binding. Card on a number of agreements, if bound, when the data through the network card, the computer would take a lot of time to determine which protocol to use this data to send, then the user will feel the Internet slow. The solution is: Let a network card to connect only to run the PPPOE protocol ADSL, to provide external access to the Internet connection, the other to run the LAN card and other agreements to fulfill their job performance, so the client connection speed will be improved.
2.ADSL bad cooling equipment.
ADSL equipment work more than fever, usually pay attention to cooling, many users the ADSL equipment and routers, hubs, etc. in a cabinet, the work of a variety of equipment cooling, affecting the normal operation of the ADSL. Just surfing the web as normal, 5 minutes, speed down, download speed and narrowband 56kMODEM the same time a very hot hand touch equipment, for an ADSL device, the speed will come up. Therefore, computer, ADSL and other equipment not on the same cabinet, to be distributed display, equipment, ventilation and heat dissipation between the left channel, computer room temperature is best achieved, the general ambient temperature should be controlled in 10 鈩?~ 30 鈩? Relative humidity was maintained at 40% to 70% as good.
3. Access to the Internet interface error.
This is because Windows (Windows software) IE Internet Connection Wizard to specify access to the Internet interface error caused, Enterhet300 (virtual dial-up software) using a type of virtual LAN dial-up, while the IE default using ordinary dial-up, visit the first time IE looking for dial-up interfaces. Can not find the dial-up later on there to find the proxy server inside the LAN, and finally will find Enternet300 this interface, it will be very slow, only to re-run again Internet (Internet) connection wizard, select the LAN mode, and removed the automatic search for proxy servers solved.
4. System does not support multitasking.
If the user's computer just meets the minimum configuration, this system can not support while browsing the web, downloading software, music and many other tasks. A variety of tasks while at work will feel the Internet slow. Thus, while generally not more than two tasks as well.
5. Does not bind TCP / IP protocol.
Unbound TCP (Transmission Control Protocol) / IP (international agreement), and more for the network card drivers installed without a good, quality card problem, PCI (bus standard) slot bad. Should first device manager to delete the network card driver, reboot and install drivers; if not good, the card for a PCI slot, and back to a network card can not good.
6. Telephone lines and poor quality.
ADSL technology requires high quality of telephone lines, ADSL is currently used RADSL (ie rate adaptive ADSL), if the telephone office to a telephone line between users in a certain period of time, interference by external factors, RADSL based on line the quality and transmission distance, dynamically adjust the user's access speed. If access to the foreign site, bandwidth and speed will be subject to export other Zhandian lines, equipment configuration and other factors, need to keep the network Xietiao with the solution. Line problems are: because the construction did not follow the construction standards, quality left hidden, such as mice did not result in additional plastic casing snapped line; patch panels or other materials due to quality problems, leading to poor contact jumper; users renovation dark apply the interior line of failures.
7. Software is not reset.
Users install ADSL broadband, the Internet has changed the conditions, the corresponding tools are not re-set, is also one of the reasons causing slow. Such as communications software QQ, will need it for some settings. Select from the QQ panel "System Parameters" command, click on "Network Settings" tab, the original "dial" to "LAN access Internet" on it.
8. Microcomputer hardware and software problems.
Hardware failures mainly in the user card is damaged or not properly installed; user computer motherboards and network cards are not compatible; user computer grade is too low, leading to slow less memory. Such as hardware configuration Celeron 600/64MB memory, WINDOWSXP operating system, will lead to very slow running computer, Internet speed would be higher. Software failure was mainly due to computer users do not understand the knowledge, in the course of misuse, leading to damage to the operating system error or dial-up software can not access; user does not operate correctly, so dial-up software illegally closed, leading to software errors; users after browsing some pages , system problems, when dealing with accidentally deleted the backup dial-up software; user computer problems, reinstall system, dial-up software is not installed. As long as these problems can re-install dial-up software fault exclusion.
