【 Weak current college 】 thoroughly explain the LAN wireless router problems

In the local area network, we often encounter a wireless router, how to verify the origin of these questions? today's society the rapid growth of information technology, today's enterprise network Office also formally into the category of wireless network.

Build a wireless network, the biggest benefit is the network without the need for wiring, using convenient, economic. So for non-minority enterprise is undoubtedly the best selection of networking scheme. A large number of wireless routers are used in the enterprise, making for a wireless network fault diagnosis and security has become just like the main with the wired network. In enterprise wireless network Office often there will be some use of the manual did not touch questions and wireless router problems, sometimes difficult to handle. The following network Knight on a wireless network router is thrown in by typical wireless router analyses with implementation, and to provide a treatment plan.

Convergence error line barrier

Network line access to the many reasons to form, but first you want to test the connection configuration errors. To ensure that the router power good premise was the first to check for broadband access. The lights on the router can indicate a broadband line access client can not be normal, by indicating on which one can recognize light as broadband access client and the user side, the observation of his Daddy, continue blinking as normal, not light or long light does not Flash to order. We can change a broadband glue line instead of the original line implementation of the interface. Assuming that your wireless router doesn't work as usual, check the placement of routers and accepted computer interval can too far or in the middle of a large obstructions blocking. When you reposition the router, enabling wireless router and accepted computer don't interval too many obstructions, and make the admission of computer in a wireless router's signal transmission range.

Wireless card inspection is also essential, you can replace the new NIC device driver-neutral new order execution and debugging, and then click the "check the network card available for wireless convergence" refresh list "network" configure the network adapter parameters, and then "Properties" check nearly as far as send and to accept, remove the wireless router. Of course the router hardware defects itself is also a direct line not incurred reasons, but it's not all we can handle, please contact the manufacturer to perform a repair or replacement.

Misconfigured cannot link up

The "configure" can be divided into computer configuration, router configuration in two ways. The configuration of your computer, it is relatively easy to enter "network places" properties, "wireless network connection", and then configure the "IP address" and "subnet mask" and "gateway", simply give the IP address of the computer and the wireless router's IP address on the same network segment. The "gateway" configuration you can see the card marked with that described in ordinary circumstances, and router IP address is the same.

Router configuration is relatively more professional, complex. First the system browser enter the wireless router IP address on the pop-up login interface input router maintenance member login name and password to enter the configuration interface. You need to test the network service provider to your broadband account number and password can not correctly, such as incorrect, try link corrected, assuming convergence still can't open the page please click into the router's "security configuration" option, to check whether or not we can open the "network firewall," and "IP address filtering" and "MAC address filtering" option, and make corrections and configure, remove cannot open a network of wireless router problems.

Network attacks by networking exception

ARP attacks and unlawful intrusion not fortification of wireless LAN was now incur networking exception cases. Because the security configuration's negligence and lack of protection of late, incur few malicious hackers to primary information and confidential data formed the great harm. ARP attack will form a network IP subject, data loss and overflow, moreover can lead to paralysis of the network. The scene-to-business networking threats are great. First enter "with network security approach", in the wireless network connection properties, replacing the IP address of the computer, after checking can be networked. In addition to purchase specialized antivirus software and firewall is one of the ways analogous shortcut.

Then enter the router "security configuration" option to perform an advanced configuration. Today's big local wireless router has a WEP password encoding function, with a maximum length of the password key 128bit data encoded in the implementation of the communication on the wireless router, the password key length can pick 40bit or 128bit, use Mac address and preset network ID to qualify what wireless network adapter and access point can gain access to the network, can ensure that the network security, regarding unlawful accepts this term, the interception of wireless network signal is very difficult, thus effectively preventing hacker intrusion damage and not legitimate users from malicious Internet attacks. It should be noted at the beginning, in the absence of special need or do not have the professional skills of the Suppression of open router "Remote WEB maintenance", function options.

Router local function failure cannot use

The questions are mostly present in some older wireless router, when we configure the router advanced functions option from the sky, in repeated confirmation link and correct situations is a partial function application could not be opened, then you might first think could be a hardware fault with the wireless router, would have been otherwise.

First we have to check the version of the next router system, access to the wireless router, see the indicated functions can not support this version of the router system. Router systems typically have many versions, each of which versions support different functions. Suppose you now software version does not support this function, you should find the appropriate software, to do the promotions. Click to enter the wireless router's "System Tools" option, enter the following selection "Software promotion", at this point in the dialogue interface displays appear in the software version and the hardware version, in the pop-up dialog box, enter "file name" (i.e. the name of the file system promotion) and "TFTP server after you click on the" IP "Promotion ".

When to pay attention to the promotion: selection and now hardware version consistent software Executive promotions, promotions process do not turn off the power to the router, the router will incur damage cannot, in the case of fixed network promotion process is short the entire process does not exceed one minute. When you are aware of the router at the end of the cycle before, do not worry this is normal. Regular promotions, the router task will increasingly fixed and added some applicable to this version more new functions.

Conclusion:

Enterprises in the huge market situation, the information and data confidentiality and security is the number one event in its use of the wireless network, LAN Security Questions has become particularly major, a lot of people to ask: to seek the invisible radio waves carry data transmission of wireless LAN security guaranteed? originally WLAN than non-minority wired LAN Security. Wireless LAN security features inherent to many focus on trade secret industry use wireless LAN became able to, but how the security of wireless LAN and then also get wireless router problems, just regular inspection, promotions; timely replacement and maintenance can prevent network problems severe depletion.
