Instantaneous drop failure: Double packet loss is caused to cause transients. At this point, the intact network is normal. The outgoing network line is normal to stand-alone test.
Solution 1: Close all switches in the LAN after 5 minutes. Re-turn on the power, observe whether the network returns to normal! (CAUSE: It may be that the switching machine does not restart its memory has been used, causing the exchange data to be slow, or the impact of the network storm is blocked) (the other may be damaged by a switch, or switch failure The network of the network caused, the solution is to replace the switch)
Solution 2: Find a machine to install a CommView, the IP address is set to your router IP (unplug the router, make it out of the network), then you see what packages have been sent outside, see which machine has the most What IP is sending? If you find that a machine is sent outward, the ip is a continuous package, and the speed is very fast, please repair the machine! (Probably because a certain or multiple machines in the local area network infect worms, in the crazy bag, resulting in the router NAT connection to full)
Solution 3: If the above two reasons are excluded or unable to solve their problems, it may be that your router is poor performance, processing power is limited. You can make a software router such as Route OS, or buy hard routes from 3,000 to 5,000 yuan, and replace it to observe.
Solution 4: Some / a few computer network card interface inside the local area network is corrupted, and the network blocking will be sent to the network. (The integrated network card is prone to this problem, especially if this problem is more difficult to check, it can be disconnected to disconnect a switch to disconnect a switch. The machine has problems in confirming which switch in the switch. Top these machines, enter the desktop, exit all management software, open the network connection, do not do anything, see who is in a large number of bags or bags
Solution 5: (This situation is special: some people in the LAN use illegal software malicious attack Internet cafes or ARP virus attack networks) In some software that blocks the illegal attack Internet cafes in the technician production of the parent, the gateway Mac The static ARP binding now has a lot of hard routers with special anti-offline features, our online cafes can, can broadcast normal ARP packages, if you are software routes, you can use the software to protect, I Under the collection, everyone can click to download! Recently, my friend has a network can't have a drop condition. Other computers are good, just this look, the hard disk is heavy, the 2000, XP system, still not ASUS 915 motherboard, integrated network card), finally put the network card to the new version, huh, you are scaining !!
