In order to facilitate access to surfing, and many units and even families are beginning to use wireless Internet access Networking method, but many of my friends in the formation of a wireless network often encountered in the process of IP address conflict embarrassing, it is because the use of any one of the TCP / IP workstation to connect to the Internet or Intranet network, will have to use relatively independent of the IP address, only with the correct IP address workstations to access other workstations in the network. However, with the continuous deepening of network applications, as well as group size of the network continues to expand, the number of workstations in the network may be drastically increased, as an IP address to the phenomenon of conflict is almost inevitable. In order to effectively improve the efficiency of a wireless network, we can proceed from the following aspects to make the wireless network, "rejecting the" emerging IP address conflict phenomenon!
Starting from the card set up, "refused to" address conflict
IP address conflicts arising from the many reasons, of which there is a very important reason for this is that local computer network card physical address of the computer's network card and other duplicate addresses, resulting in the local computer was unable to connect to wireless networks; this IP address the appearance of conflict settlement, in accordance with the needs of the distribution of IP addresses to different targeted manner.
Under normal circumstances, a wireless network equipment to wireless routers in the usual way to use DHCP server management workstation's IP address, this management approach provides us with a three IP address assignment: the first modes of distribution for the "automatic distribution ", in which addresses methods of distribution, as long as an ordinary wireless network workstation first time DHCP server successfully leased to the IP address, then the address of the workstation will always be occupied; second modes of distribution for" dynamic allocation ", in which addresses methods of distribution, the wireless network from the general workstation once DHCP server-side access to IP addresses, not always to the occupation of the address, once a system reboot or address after the expiration of the lease, it must be ordinary workstations previously occupied by IP address released, to give wireless network, and other workstations; third modes of distribution for "distribution", that is to say not to the general DHCP server workstation assignment of IP addresses, users can network under the unified planning from the redistribution of IP addresses.
When wireless routers DHCP server in a "non-distribution" approach, we must be designated for the general workstation appropriate IP address, if not specified IP addresses so that ordinary workstation does not have access to a wireless network, if the allocation of IP addresses incorrect so, the general workstation can log network, if the designated IP address duplication, then there would be easy to create a wireless network IP address conflicts. When wireless routers DHCP server in a "dynamic allocation" approach, ordinary workstations generally does not require specific IP address, if we are to set up a workstation for the IP address, so can easily create a wireless network address conflicts phenomenon, or lead to general Sign workstations normal wireless network.
According to the above analysis, we can be triggered with a wireless network failure occurred address the reasons for the conflict to take specific measures to deal fault of the wireless Internet. For example, once the wireless routers do not use DHCP server, then we must be designated for the general workstation appropriate IP address, if the opening of the wireless router has a DHCP server, then we will be in the general workstation previously allocated IP address cancelled That is to say IP addresses will be adjusted for "automatic access to IP addresses."
The opening of the wireless routers DHCP server circumstances, if the IP address conflict in the phenomenon, then we need access to ordinary workstations where the Windows system, followed by clicking "Start" / "set up" / "network connection" / "local connection" order, in subsequent local connection status of the pop-up window, click "Properties" button, open the local connections attribute interface, the interface of "conventional" label pages, check the "Internet Protocol (TCP / IP) "and then click on the" Properties "button and enter the indicated parameter settings interface, the interface selected in the" automatic access to IP address "and click" OK "button, and then restart a workstation systems , as a general workstation will be able to obtain a new IP address.
Of course, if ordinary workstations installed Windows 98 operating system, then we can turn click "Start" / "Run" command in the pop-up dialog box in the operating system input string order "winipcfg", click "OK" button, and then later in the pop-up interface, click the "release of all" button, click after the "updated" button, as an IP address to the appearance of conflict can be resolved. If ordinary workstations installed system is Windows 2000 or Windows XP system, then we can turn click "Start" / "Run" command from the pop-up dialog box in the system running order of the string "ipconfig / release" alone hit "OK" button, the general workstation originally obtained from a DHCP server on the IP address was released, the operation of the system after the implementation of the dialog box, "ipconfig / renew" orders from the DHCP server will be able to obtain a new IP address the.
The opening of the wireless routers DHCP server circumstances, we can amend the lease parameters of a wireless network to resolve the IP address conflict fault. The so-called "lease period," actually refers to wireless routers DHCP server distribution to the general workstation using the IP address of the effective time, if we set up a network of wireless networks with high flexibility, it can try to lease time to adjust a slightly shorter; If the wireless network is set up specifically for fixed users, then we can try to lease for a little longer time to adjust some, to avoid a validity period, the IP address conflict-prone phenomenon.
In addition to general DHCP server workstation unable to obtain the correct IP address, there is a situation can easily lead to a conflict of IP address, that is, ordinary workstations installed at the same time the multi-block LAN equipment, some of which card if no parameters set up correctly, also easily lead to address conflicts, therefore, when we encountered the unfortunate phenomenon IP address conflict, we must be serious in the current inspection workstations have been installed multi-block LAN equipment, if that is indeed how workstations block card , in addition to being used to check the card parameters, it would be better not to use the other card temporarily disable equipment swap.
Starting from the proxy settings, "refused to" address conflict
We know that when the use of wireless networks, such as model to network, each wireless workstations need to use the same name and SSID channel, multiple workstations will be set up as a wireless network. In this mode network workstations to share access to be achieved, we need to use third-party proxy server software or use the built-in Windows System Proxy Server software. In this sharing of Internet circumstances, any one of the workstation's IP address should be set to the same network segment at the fixed address, This makes by hand in the assignment of IP addresses can easily address allocation will be caused by the same IP conflict; In addition, since many procedures in the default proxy servers are often under the state will open a DHCP server, if this wireless Internet workstations in the network parameter set to "automatic IP address," then the workstation from the proxy server may automatically receive an IP address, as an IP address to also prone to the appearance of conflict.
To avoid the proxy server address conflicts arising from the phenomenon, we can open the IE browser window, and in the window menu bar click "Tools" option from the drop-down menu pops up after the implementation of the "Internet Options "Order, open Internet Options Settings dialog box;
Click on the Settings dialog box followed by the "link" label, and labels in the corresponding pages, click the "LAN settings" button, as shown in parameter settings open interface; interface settings in the "proxy server", check the the current workstation is not using a proxy server connectivity, the use of the already If so, then we must promptly cancel it, then click "OK" button, as a proxy server to the IP address will not be automatically allocated to the general workstations, so Address wireless network in the possibility of the appearance of conflict will be greatly decreased.
From the set of routing, "refused to" address conflict
Apart from the above factors will cause several wireless network IP address conflicts may arise phenomenon, wireless router or wireless AP and upper wireless network equipment installed at the same IP address, but also easily lead to address conflicts phenomenon. For instance, many brands of wireless routers or wireless AP default IP address usually is 192.168.0.1 or 192.168.1.1, and now many brands of ADSL equipment to use the default IP address for 192.168.0.1 or 192.168. 1.1, as a result if these two types of equipment in the same paragraph of a network, it would address the appearance of conflict is high, resulting in the denial of normal access wireless networks.
When we address this unfortunate experience of the conflict, we may wish to separate wireless router and ADSL equipment connected to the local workstation, through "ipconfig" orders or "winipcfg" order check their default in the same IP address whether a subnet, if established, we will have a timely changes which the equipment of the default network address, refused to link the two devices address conflicts occurred when the phenomenon. |
