The use of local area networks is very common, but there are many problems. Especially speed. So how to solve the failure of a LAN transmission speed is slow? Let us introduce it in detail. A newly built small local area network, a server, a dozen workstations, using a switch as access equipment, the connection line is Category 6 line. The main fault is the slow transmission rate of the computer LAN in the network. Any workstation copies a 100MB file on the server, which takes 30 minutes. Even two adjacent workstations are so slow. Failure analysis and list the following possibilities: 1. Hacker attack or medium worm * 2. Line fault 3. Switch overload 4. Network adapter failure 5. Connectivity issues Troubleshooting method: 1. Choose any number of workstations arbitrarily and check its network configuration. Able to ping the server, the response time is <1ms, which is within the normal range, that is, there is no problem with connectivity. WINDUMP was installed on one of the computers to obtain the data packets, but no problems were found, so the possibility of hacker attacks or worms * was ruled out. 2. When troubleshooting the line, we know that all computers have the problem of slow transmission speed of the computer LAN in the network; so the most likely problem is the wiring pass rate of the 6 types of lines. It is very simple to know whether it is the wiring of Category 6 lines, as long as the Category 6 line is replaced with a Category 5 line; if the computer transmission speed in the network becomes faster, it means that the Category 6 line has a problem; but within the network The transmission speed of the computer is still slow, indicating that there is a problem with the Category 6 line. This situation is unlikely. 3. It depends on whether the switch is overloaded or not. Just restart the switch and see if the computer transmission speed in the network becomes faster; but it is useless here, so the possibility of overloading the switch is excluded. 4. Randomly checked the network card status of several workstations and found that the network cards of these computers were in half-duplex state. And deleted some unused network protocols, the fault still exists. 5. Finally, when there is no way, after logging in to the switch using the Web management method, I checked the error status of each port and there was no problem; but it was unexpectedly found that each port of the switch was forced to a full-duplex state; we recall the workstation The NICs are in half-duplex state. Is the problem of port mode mismatch causing the network speed to slow down? Therefore, after changing the port of the switch to the adaptive state, the fault is resolved.
