局域网网速变慢的五种解决办法（Five solutions to slow down LAN speed） In computer networks, especially LANs, the occurrence of network failures is inevitable. In the early stage of LAN construction, in order to facilitate the maintenance of network lines later, it is better to make a plan in advance before the design of the circuit. The network layout of the design is clear at a glance. As a network fault diagnosis is an important work of network management. Generally, when the network information access, can browse the Web connectivity fault, fault phenomenon is clear, according to the layout of the cable is easy to observe and locate the fault point, the fault is not difficult to solve. The biggest headache, though, is that the LAN network is open, but the network is slow. Most people are faced with this kind of failure, they tend to get along and make use of it. In fact, they do not know that this situation can be solved. This article introduces the common causes and troubleshooting methods of this kind of trouble, so as to improve the ability to deal with practical problems. First, the worm virus and the ARP virus cause the network to slow down The worm viruses transmitted through E-mail and ARP spoofing Trojan viruses have more and more serious impact on the network speed, and they are extremely harmful. This virus has infected users as long as the Internet did not stop to send mail, random address selection of random virus document user personal computer attached to the user machine address book on the mail. Hundreds of such junk mail are queued to send out, and some are returned to the server in batches and batches, resulting in obvious congestion on individual backbone networks, and the network speed is noticeably slower. While using ARP spoofing trojan virus attack, will send a large number of packets, resulting in LAN communications congestion, users will feel the Internet more and more slowly, so that the LAN is almost paralyzed. Therefore, we must promptly upgrade anti-
