Internet speed on the issue! !

Users questions: This year my house just to the Internet! But the lack of many problems! I have that is 188 monthly subscription! Logically it should not slow to say! Why is my download speed is only 10 ~ 30KB 188 other families also have a monthly download speed is about 200KB ah! What went wrong? ? ? (Forget One thing. The time has come just installed an amateur may not work the installer to install him go and get a telephone line to connect the road tour and then get telephone lines to connect to my computer! A connection! No phone signal immediately! Is not this causes it? )
Experts answer: Wang Suman causes and solutions! 1, the network you want to connect their own problems, the target site where insufficient bandwidth or server load is too large. Approach is simple, make another time or another to a target site. Second, network cable problems led to slower speeds we know from the four pairs of twisted pair wire according to strict rules and twisted closely together, Used to reduce crosstalk and background noise. Meanwhile, in the T568A and T568B standards standards using only the four twisted pair lines 1,2 and 3,6, which is used to send 1,2, 3,6 for receiving, and must come from a 1,2 around the right, must come from a 3,6-around right. Just In this way can the maximum to avoid crosstalk, ensuring data transmission. I found in practice is not the correct standard (T586A, T586B) produced by cable, will be dangerous. As follows: one case is just the beginning very slow speeds when used; the other case is the normal starting speeds, but After a period of time, speed slow. The latter case, the performance of the desktop is very obvious, but check with the laptop but showed normal speeds. For this problem I discovered after years of practice, standards for not making the correct cable speeds due to slow Huan also related to the quality and the network card. General Desk Type the computer's network card's performance as notebook computers, and therefore, with the exchange troubleshooting, the use of laptop computers and can not rule out the normal testing speeds do not follow the standard cable making this a problem. We are asking all by T586A, T586B standard network cable to suppress, the fault detection Can not be used when the laptop instead of desktop computers. Third, there is a network loop leading to slower speeds when the network nodes involved are not many, the structure is not very complicated, such phenomena seldom occurred. However, in the network more complex, often redundant backup line, Ru will inadvertently connected to Constitute a loop. Such as network cable to your computer from the network center of a room, and then received a computer from the computer compartment of a room. At the same time there are a backup from the network center line directly connected to the computer compartment, if the several lines, turn, constitutes a loop, data packets will continue to send and check data to affect the overall network speed . This situation is difficult to find. To prevent that from happening, ask us to lay cable in a certain good habits when: cable marked Mingxian the label, You Beiyong place to make records. When suspected of such failure occurs, generally use the partition section stepwise approach. 4, network equipment Broadcast storm caused by hardware failure which led to slower speeds as the main means unknown device was found, broadcast in the network plays a very important role. However, with the increase in the number of computers in the network, the number of broadcast packets to increase dramatically. When the number of broadcast packets to 30%, the network transmission efficiency will be Decreased. When the network card or network equipment is damaged, we will continue to send broadcast packets, resulting in broadcast storms, so that network traffic paralyzed. Therefore, when the network device hardware failure can cause speeds are slower. When suspected of such failure, the first displacement method can be used to exclude replacement hub or switch set Line of equipment failure. If the equipment does not malfunction, turn off the power after the hub or switch, DOS used under the "Ping" command on each of the tests related to the computer to find the faulty computer card, replacement of the card can resume normal speeds. Cards, hubs and switches are the most vulnerable Slow speeds caused by equipment failure. 5, the network bottlenecks leading to the formation of a port speeds slower in fact, the router WAN port and LAN ports, switch ports, hub ports and the server network card and so may become network bottlenecks. When the speeds slow down, we can use in the network peak hours, benefits View Network Management software with routers, switches, server port of data traffic; also be used Netstat command data traffic statistics of each port. Accordingly confirm the location of network data flow bottleneck, try to increase the bandwidth. Many specific methods, such as the replacement of the server network card to 100M or 1000M
