【 Weak current College 】 wireless router application fault address ARP attack

<br> <BR> With the current rapid development of information technology society, office of the enterprise network has now formally entered the field of wireless networks. .Construction of the wireless network without biggest advantage is that network cabling, easy to use and economical. .So for most enterprises, network scheme is undoubtedly the best choice. .<BR> <BR> Large number of wireless routers are used for business, making for fault diagnosis and wireless networks and wired network security becomes as important. .<BR> <BR> Office in the enterprise wireless networks often use the manual will be some difficult and is not involved in trouble, and sometimes difficult to cope, can not be resolved. .Here's wireless network caused by the router, the typical failure analysis, and provide solutions. .<BR> <BR> <BR> <BR> Connection error line network lines unreasonable barrier there are many reasons, but the first thing to check is the connection configuration for errors. .<BR> <BR> Power to ensure that the router first check the premise of normal broadband access terminal. .Lights on the router side can explain whether it is normal broadband access lines by the manual which can identify light for broadband access and client to observe the light shining state, continuous blinking as normal, or long light does not shine .the fault is not blinking. .We can glue line for a broadband line to replace the original connection. .<BR> <BR> If the problem persists, please see the placement of the router and the receiver is too far away from the computer or the middle of large obstructions. .Then please re-place the router, wireless router and receiving computer to do too many obstacles interval, and to the wireless router to receive the computer within the scope of signal transmission can be. .<BR> <BR> Wireless card check is also essential, you can replace the new card and re-install the driver for debugging, then card, click "View Available Wireless Connections" refresh "network list" after the set card parameters, and .and then "Properties" to view the availability of data transmission and reception, troubleshooting. .<BR> <BR> Of course, is the router's own hardware failure caused a direct line makes no sense, but this is not what we can to resolve the scope, should promptly contact manufacturer for repair or replacement. .<BR> <BR> Set incorrectly can not connect <BR> <BR> "set" the computer can be divided into two aspects of settings and router settings. .<BR> <BR> Relatively simple computer's settings, click into the "My Network Places" properties, open the "Wireless Network Connection" and then set the "IP address" "subnet mask" and "gateway", as long as the computer's IP .address and IP address of the wireless router can be in the same network segment. ."Gateway" setting to see the card as described in note that, under normal circumstances and the router IP address of the same. .<BR> <BR> Relatively professional setting of the router, more complicated. .First, the system browser, enter the wireless router IP address, the login screen pops up, enter the router's administrator login name and password to enter the setting interface. .At this point the need to check the network service provider to your broadband account and password is correct, if not correct, correct, and try to connect, if the connection still can not open the page into the router, click the "Security Settings" option, see if open ."Network Firewall", "IP address filtering" and "MAC address filter" option, and make corrections and set, remove the fault network can not be opened. .Network attacks lead to abnormal <BR> <BR> <BR> ARP attacks and hacking wireless LAN without fortification has now led to a typical case of a network anomaly. .The negligence of the security settings, and lack of post-security, leading to a small number of malicious hackers with important information and confidential business data caused great harm. .<BR> <BR> ARP attack will cause the network IP conflicts, data loss and overflow, worse, would bring down the network. .These phenomena are all threats to the enterprise network great. .<BR> <BR> First to enter "safe mode with network" in the wireless card property at the replacement of the computer's IP address, then see if you can network. .In addition to purchase and install specialized antivirus software network firewall is more one of the shortcut. .<BR> <BR> Followed into the router, "Security Settings" option for advanced settings. .Most wireless routers now have a WEP password encoding, password use up to 128bit keys to encode data, to communicate on the wireless router, password, key length can select 40bit or 128bit, use a network MAC address and default .ID to restrict wireless LAN and access points which can enter the network, can ensure network security, for the illegal delivery of this, the interception of wireless network signal is very difficult, which can effectively prevent hackers and illegal destruction of .users to malicious network attacks. .<BR> <BR> Finally, note that, in the absence of special needs or does not have the professional skills of the case against open the router's "Remote WEB Management" option. .Some features of the router failure <BR> <BR> <BR> <BR> can not use most of this problem exists in some of the old section of the wireless router, when we advanced features option to configure the router when the connection is correct in the case of repeated confirmation .The following are some of functions not open to use, then you might first think of whether it is hardware out of the failure, it is not. .<BR> <BR> We need to see the version of the router system, access to the wireless router in the manual, to see whether the function supports this version of the router system. .Router system usually has many versions, each supporting different functions. .If your current software version does not support this feature, it should find the appropriate software, the first upgrade. .<BR> <BR> Click to enter the wireless router's "System Tools" option, enter and select the "software upgrade", then in the dialog interface will appear in the current software version and hardware version of the dialog box, enter ."file name" (ie, upgrade the file name) and the "TFTP Server IP" and click "Upgrade" button. .<BR> <BR> Upgrade to the attention of: Choose consistent with the current hardware version of the software upgrade, the upgrade process do not turn off power to the router, the router will cause damage can not be used in the network stability of the upgrade process .The whole process is very short no more than a minute. .When you find a router reboot after the upgrade, do not worry this is normal. .After the general update, the router will be more stable work and for this version to add some more new features..
