Troubleshoot wireless network mutual access

The development of wireless network technology is growing, and the problem of wireless signal in network use has always been a problem of network signal. Here we will give you a detailed answer.

As wireless Internet technology continues to mature and wireless network equipment prices continue to decline, wireless LAN "figure" is unconsciously appearing in our work and life. Compared with common LAN mutual access operations, wireless mutual access is more prone to some inexplicable fault interference. In the face of these faults, many people often feel unable to cope with them. In view of this, this article will now contribute to the frequent occurrence of wireless mutual access failures and solutions, so that you can enjoy the smooth sailing of wireless mutual access operations in the future!

Wireless Network mutual access fault 1. Access is unavailable at intervals

Mr. Wang and Mr. Zhang share and exchange their respective documents and materials through the wireless LAN in the office. However, during mutual access, such a strange fault often occurs, that is, when files are transmitted to each other, the wireless network transmission speed is very fast. However, if no access is made for a while, the wireless network prompts that the network connection has been disconnected, you cannot perform any file transfer operations. So why is this fault? How can we make the wireless exchange operation smooth?

In fact, in most cases, this phenomenon is sometimes not a network fault, because most wireless LAN devices use wireless router devices, which often provide users with a variety of communication methods, however, most wireless router devices use the on-demand connection mode by default, the wireless LAN automatically connects when detecting a data transmission. If no data is transmitted over the network after a period of time, the wireless LAN considers the current network line to be in the no-load status, then it will automatically disconnect the current network connection, so when we try to access each other through the wireless network next time, the wireless LAN will naturally prompt that the connection has been disconnected.

To avoid this problem, we first need to log on to the background configuration interface of the wireless router, and find the connection method setting options in it, set the option value to "automatic connection, automatic connection after startup and disconnection", save the configuration parameters, and restart the wireless router device, I believe that wireless LAN will not frequently disconnect.

Of course, if, after the above settings, the wireless LAN still drops out of line at intervals of time, therefore, it is necessary to check whether the current wireless LAN has been attacked by network viruses or hackers. For example, if the LAN has been attacked by ARP, the network is often inaccessible at intervals.

In this case, open the network connection List window of the local workstation, right-click the wireless network connection icon, and click the "properties" command from the shortcut menu, open the Property setting window for wireless network connection. Select the "TCP/IP" setting option in the setting window, and on the corresponding option property interface, try to manually Replace the IP address of the wireless network card. If the IP address is updated for the wireless network card, the local workstation may still be disconnected frequently, then we only need to use professional anti-attack software to protect the inter-access operation of the wireless LAN.

Failover of wireless networks II. slow server access

Mr. Li needs to upload the accounting information of the day to a specific folder on the server every day through the wireless LAN, so that the leader can review the information in a timely manner. In the past, when the account information was transmitted to the server, it could be completed in the twinkling of an eye. However, after the Unit recently adjusted the placement of the wireless router, when Mr. Li uploads an accounting file of the same size as the previous one to the server, it takes a long time to wait. So why is the speed of transferring files to the server suddenly decreasing? What measures should we take to restore the rate of mutual access between the workstation and the server?

Considering that Mr. Lee previously transmitted information to the server at a normal speed, but after adjusting the router equipment in the wireless LAN, he realized that the transmission speed of the wireless network dropped significantly, this indicates that the fault may be due to the location change of the wireless router, resulting in weak wireless signals. Of course, the Unit server may be busy for some time, as a result, Xiao Li's access speed to the server is affected.

The access speed reduction Fault Caused by the busy server of the Organization is usually not solved by ordinary users. What we can do is to avoid server access peak hours as much as possible, at the same time, the best way is to ask the network administrator of the organization to try to improve the running performance of the server and ensure that the server can respond to user access requests in a timely manner.

Frequent access speed drop failures caused by placement of wireless routers are also common and often ignored by common users. When the placement of the wireless router is not timely, the wireless signal that the wireless workstation can receive is relatively weak. Therefore, when it transmits files through the wireless network, the speed will naturally be slow.

To solve this fault, we can place the wireless router in the center of the wireless LAN, and ensure that the equipment and other wireless workstation cannot be separated by a large cement wall; another thing we need to do is to try to place the wireless router in a high position. Only in this way can the wireless workstation obtain a high-intensity communication signal, in this way, the server access speed can be effectively improved.

Wireless Network mutual access fault 3. Access to the Internet via LAN

A wireless LAN is set up for an organization, and its employees can directly access content in the Internet through the wireless LAN. However, one day, when employee Meng opened his workstation and prepared to surf the Internet, he found that he could not access the content in the Internet. When he checked the wireless network connection status, he found that the system prompts that he could send information externally, but cannot receive information. In the case of such access failures, how can we help employee Xiao Meng correctly access the content on the Internet?

First, check whether the workstation of employee Xiao Meng is physically connected. When performing this check, open the IE browser window of the local workstation and enter the background management address of the wireless router in the address bar of the window, click the Enter key to open the background logon interface. Then, enter the Administrator account and password correctly to go to the background management interface of the wireless router. In this interface, Ping the DNS server address of the local ISP, if the Ping test is normal, it means that the connection between the wireless router and the Internet is smooth. Otherwise, we need to check whether the connection parameters of the wireless router are correctly configured.

Next, find a common workstation in the wireless LAN, and switch the interface of the workstation system to the MS-DOS window, and then execute the string command "Ping aaa. aaa. aaa. aaa "(aaa. aaa. aaa. the aaa address is the internal interface address of the wireless router, that is, the gateway address of the local network). If the command can be executed successfully, it indicates that the line connection in the local LAN is normal. Otherwise, we need to check the correctness of the wireless router configuration and workstation configuration, and check whether the lines between them are smooth.

If the above Ping tests are successful but cannot be accessed, we also need to check whether the Internet parameters of the common workstation are set correctly, for example, whether the gateway address and DNS address inside the workstation are correct. After confirming that all these parameters are correct, we can check whether the NAT configuration of the wireless router is correct. If we cannot find any errors from the router configuration, check the NAT address translation table again. Of course, this function requires the support of our wireless router.

Wireless Network Access failure 4. Access to the wireless router background Interface

Recently, IP addresses in the wireless LAN of the organization often conflict with each other. After careful inspection by the organization's network administrator, it was found that in the LAN, apart from a dedicated DHCP server, the DHCP Service in the wireless router is also "grabbing" the IP address assigned to the workstation, so that the IP address of the workstation is prone to conflict. To eliminate IP address conflicts, the network administrator wants to log on to the wireless router background interface and temporarily disable the DHCP service that has been enabled, but who once thought that when James attempted to log on to the wireless router backend in his workstation, how could he not open its background logon interface? Why?

There are many causes of such a fault. Different causes need to be addressed in different ways. Among them, the hardware fault causes are common, such as network cable breaking or short circuit, and network connection joints become loose, the wireless router has hardware faults. For the reason of hardware failure, we usually only need to check the signal state in the control panel of the wireless router to determine whether the hardware is faulty. Of course, if the input voltage of the wireless router is abnormal, the temperature inside the device is too high, or the device is struck by lightning, the background interface of the wireless router may fail to be accessed.

To eliminate the problem that the backend interface of the wireless router cannot be accessed, we first need to check whether the data signal lights in the wireless router control panel are working normally. For example, when the power signal lights are intermittent flashing, it indicates that the input voltage of the device is normal. If other signal lights in the control panel of the wireless router are abnormal, we only need to perform targeted troubleshooting based on the status of the corresponding signal lights.

If the background interface of the wireless router still cannot be accessed after hardware is excluded, check the network connection parameters in the local workstation, in particular, check whether the IP address is in the same subnet as the default IP address of the wireless router. If not, we may wish to assign a suitable IP address to the local Nic again, in addition, try to temporarily block the firewall function in the local workstation. We believe that this will certainly solve the failure of accessing the wireless router background interface.

Of course, if the above operation is still invalid, we may as well press the reset button in the wireless router Control Panel to restore all the work parameters of the device to the factory settings, reinstall the driver of the wireless router. Of course, if you try all the methods to solve the fault, we only need to contact the device manufacturer and check the conflicts between the related hardware.
