How to find the LAN fault

[little-Jacqueline]

Hi all,

Network often fails, just as people are sick so often, like in the event of network problems, the most important thing is not to worry, to keep a clear head. I need to identify the problem lies in where generally at what situations. Please advice. Thanks in advance.

In the "Network Neighborhood" and can not see the local computer, or open "Start / Run" using "PING" command, "PING" the local computer's IP address when unreasonable, explain your network settings, then first thought should be the card, we can open the "Control Panel / System / Device Manager / Network Adapter" setting window in the window to check whether the interrupt number and I / O address conflicts, under normal circumstances NE2000 series card for IRQ3 , 8029 chip cards for IRQ10. Card there is no conflict is found, the next step is necessary to check the Drivers the process is intact, and then re-install the network card drivers. All the best.

There are mostly LAN fault is found in the software. So in the "Network Neighborhood" check the network that can see the other computers, then your network may be agreement settings. Your network before Agreement after removal, re-install and re-set. All the best.

Check if only one computer network unreasonable, that is to open this computer "network neighbors" can only see the local computer, but do not see other computers, may be NIC and switches the connection problems, then you begin to look at the RJ-45 crystal head is not being exposed. Measuring lines and then re-use instrument,Test about whether the fracture line. Finally, check the port on the switch is working correctly. All the best.

When the entire network does not pass, it may be exchange machine or hubthe problem depends on Exchange Machine or hub is working correctly.The fault of the exclusion, so that we recognize that to strengthen the management and staff for their skills on the proficiency level required to avoid the recurrence of the work of such errors.The cable connected the wrong, by all reason should be the users can not access the LAN fishes. Check and reply.

With the continuing need for access to information, access the user is also increasing, the port is also expanded. Recently discovered that all the computers within a local area network segment 192.168.1.0 Although access to each other, share resources, but can not access to another segment of the Web server, it can not access the external network, Ping intermittent within the gateway 192.168.1.1, lost Package rate of roughly 50%. The other network computers can access the external network segment, but the Ping unreasonable 192.168.1.1. All the best.
