    How to solve the “No Network” problem?

    To build a network is a relatively easy thing, but in order to manage the network is a relatively tedious task. No Network failure which alone is enough to solve problems, because the result in the network does not make sense because there were too many. As long as we regulate the phenomenon of the failure category, or there is a pattern. I am facing some problems which are as follows:
    The connection indicator does not shine, the signal indicator light does not shine, the entire network strange unreasonable, configuration errors No Network, My Network Places can not access the. I need help related to these network problems.

    Observed RJ45 LAN side of the back of two lights. They are the connection status indicator light and signal transmission indicator light, which, under normal connection status indicator light is green, and a long bright red signal light; the normal should not stop blinking. If we find that the connection indicator, that is, the green light does not shine, so that network card to connect to the HUB or switch the connection between faulty. This tester can be used to sub-rule, if the switch to the network card from between the interconnection of multiple modules, you can use to quickly locate the dichotomy. Under normal circumstances, this failure occurred mostly network cable is not received in prison, a top reason for using the low-grade crystal. And the point of failure are mostly a problem at both ends of the connection, for example, the port at the switch and connect the computer's card at the joints, using tester can be very easy to find the fault on the solution.

    If the signal light does not shine, then no signal is illustrated for transmission, but it is certain is that between the lines is normal. Then replace the law will not prevent the use of the computer's network cable for connecting to another computer to try, or use the tester to check for signal transmission, signal transmission so if there is a local network card problem. In the actual work experience has shown that there is no information transmission network card caused failure is relatively common. This can be the first check whether it is normal network card installed, IP settings are wrong, you can try to Ping about the machine IP address, Ping General note cards if there is no problem. If unreasonable, you can try reinstalling the network card driver to resolve, while some use of an integrated network card or network card is not high quality, easy to instability phenomenon, that all settings are correct, but the network did not pass. This card can be disabled, and then re-opening of the methods, will also play an unexpected effect.

    Re: How to solve the “No Network” problem?

    In the actual troubleshooting process, for some larger network also prone to strange failures throughout the network does not make sense. It strange, because all of the phenomena appear to have normal, light, configuration are checked, and that any problems are not, but the network is not working; but also the other person takes the cake is that in the process makes no sense to still have one or two occasional computers can be intermittent access. In fact, this is a typical network of the storm, and many occurred in some of the larger network. Both the network there are many viruses, and then fled cross contamination between each other, since the computer networks are more, so that the transmission of vast amounts of data directly on the occupation of the port, so that the normal data can not be transferred. For this network the storm caused by a virus, the most direct way to solve is to find the source of the storm, when the network only need a computer to install a firewall, for example, dart network, enable the firewall you will find Firewalls stop the alarm, opens in the "security state" label in the security log to see the firewall blocking an IP address from the same virus attacks, according to IP addresses when you just find out which computers will be its killing off the network for viruses in general can solve the problem.

    The external manifestations of this failure is a network of more than a normal light, and can Ping Tung, and sometimes can access the internal network resources, but can not access the external network resources, and sometimes when you visit the Web site will be shown only by IP addresses, domain names can not be access. This is a typical network configuration resulting from improper, that does not set the correct network card, and DNS. If the gateway is set incorrectly, then the computer can only be within the LAN access, if the DNS is set incorrectly, then the access to external sites can not be resolved. We just need to open the Local Area Connection Properties window, open the "Internet Protocol (TCP / IP)" Properties window, and then set the correct default gateway and DNS server address.

    Network is smooth, with Interne, or within the LAN connection all operating normally, but by My Network Places to access the LAN can not access other computers symptoms. The reasons for this failure are more where I can give you a simple solution. That is directly on the "Run" window in accordance with the "\ \ computer name (IP address) \ share name", within the format to access other computers on the network shared folder, so that not only can get around this failure, but also than through the Network Neighborhood Access to more quickly.
