Local area after a long time continuous operation, there will always inevitably a variety of inexplicable network failure, and many network failures are often caused by the LAN router, and network administrators must learn to tune the router device, to quickly solvecaused by a router, a network equipment failure, thereby effectively improving the efficiency of network management!
1. Eliminate dial-up failure
Sometimes, we find that the transformation is directly connected with the router, computer equipment and found dial-up Internet still can not succeed.Dial-up parameters in a variety of careful examination, found and did not find suspicious circumstances; and carefully check the local area network connectivity, we found that the physical LAN connection is also normal.In this case, if still can not dial-up Internet access, we can first look at the router to restart the system; after the back-log in the router system management interface, find one of the "Connection Type" setting item, and re-set a newdial-up account, then use the new dial-up account to re-dial, maybe this can rule out the dial-up failure.
Of course, in the case of using a wired broadband links, we can transform and routers directly connected to the computer equipment, you must first power off the router device, only after the physical connection, or router equipment is prone to errors in the cache,causing the failure can not dial-up Internet access.
2. Excluded not open the page fault
In the LAN environment, often not open the page content will appear the fault phenomena, but this time using the QQ, they were normal, indicating that the local system's DNS parameters may be set incorrectly, or LAN routers parameter is not set in DNScorrect.At this point, we can first enter the local workstation's network connection properties settings window, select one of the "TCP / IP" option, then click "Properties" button, enter the TCP / IP properties settings window in which to see the localThe DNS server address is set correctly, if not correct, need to be revised over.
Parameters in identifying the correct local DNS premise, if still not open the page fault has occurred, it is mostly the DNS server address of the router is not set correctly.This time, we can log back into the router system management interface, find one of the "network parameters / WAN port parameters" setting item, then modify its DNS server address parameter on it; of course, and some parameters of the router device DNSsetting options on the "DHCP Service" setting items below, this requires our attention.
3. Exclusion can not enter the background failure
To manage the router equipment, we often will first open the IE browser and enter the address in which the default LAN IP address of the router device, from the subsequent operation of the login page, enter the default system manual administrator name and password, click "OK" button, the system sometimes suggested that it could not log on.When this happens, it may be a hardware router device connection errors; At this point, we can first check the local computer and the physical connection between the router device is correct, then a closer look at the router's LAN device control panel lights in working conditionare normal.Their work in identifying the router device in good circumstances, we can open the IE browser window, click one of the "Tools" / "Internet Options" command, then the interface will be in the "Never dial a connection" optionitems selected, then click "LAN Settings" button, then select all the options before the abolition of all selected, might be able to rule out such a background can not enter the fault of the management interface.
4. Exclude some workstations can not access failure
The same model of computer local area network, some of the normal Internet access, Internet access and some can not.In such symptoms, we can basically rule out the existence of local area network router device hardware failure, after all, some computers can access Internet content through a router.Confirm that the computer system itself in the case there is no problem, most likely in the LAN Internet ISP computers on the number of restrictions, restrictions on the use of methods is often bound IP address.To cancel this restriction, we can first use the network cable will have been bound to the physical address of the computer equipment directly connected to the router LAN port, and then bring their own addresses through the router device cloning, the physical address of the local LAN device tiedset to the router device; Finally, those who can not use manual methods to modify the physical address of the Internet computer network card, network card physical address to ensure that all of the previous physical address of the computer has the same bound, so the one will be able to solve some of the workstation can not access the Internetbroken down.
