We all know how to use wireless network technology, but when it comes to wireless network failures, how many of us know? For wireless network failures, here are some common troubleshooting skills that I have summarized for you.
Check the connection cable first to solve the problem of only sending and not receiving.
When viewing the connection status information of the wireless network, we sometimes see that the wireless network can send information to the outside, but cannot receive information from the outside. This one-way communication will obviously affect our normal wireless access operation. When unfortunately encountering the trouble of one-way communication in wireless network, we can check one by one according to the following ideas:
First of all, we must ensure that the wireless network connection line is in a smooth state. When checking whether the line is connected, we can first open IE browser, enter the IP address used by the router by default in the address bar of the pop-up browsing window (this address can generally be found in the operating instructions of the router), and then enter the login account of the router correctly to open the background management interface of the router; Then execute the ping command in the management interface to ping the DNS server address provided by the local Internet service provider. If you can ping the target address, it means that the line connection between the router device and the Internet service provider is in a smooth state. If the destination address cannot be pinged, it means that some parameters inside the router may be set incorrectly. At this time, it is necessary to check the configuration parameters inside the router one by one.
On the premise of confirming that the internal configuration parameters of the router are correct, we can find a workstation with correct network configuration and normal internet access in the LAN, and ping the IP address used by the router in this workstation. If you can ping the address normally, it means that the line connection in the LAN is also in a smooth state. If the IP address used by the router cannot be pinged, then it is necessary to check whether the network parameters used by the local workstation are consistent with those used by the router, that is, whether their address parameters are in the same network segment. If the above address can be successfully pinged, but the wireless network connection is still in the state of sending and not receiving, then we might as well focus on checking whether the DNS parameters and gateway parameters of the local workstation are set correctly. After confirming that these parameters are correct, we need to enter the router background management interface again, find the NAT parameter setting option, and check whether the option configuration is correct. In this parameter checking operation, we should focus on checking whether there is an internal network address translation entry in the NAT address translation table. If there is no conversion entry, most wireless network failures that only send and do not receive are caused by improper NAT configuration. At this point, we only need to correctly add the translation entry of the internal network address to the NAT address translation table.
Second, check the connection mode to solve the intermittent disconnection.
In the case that the local LAN is connected to the Internet through a wireless router, if the workstations in the LAN often fail to surf the Internet normally for a while, we first need to ensure that the internet access parameters between the workstations and the wireless router must be correct, and then focus on checking whether the connection mode of the wireless router is set correctly. Generally speaking, wireless router devices can support three or more connection modes, but by default, most wireless router devices will use? Connect on demand and connect automatically when there is access to data? This connection mode, in other words, the wireless router device will automatically detect whether there is no load at this time. If the device does not detect data interaction in the line after successful connection, it will automatically disconnect the wireless connection line in the connected state. Therefore, when we often encounter intermittent wireless network failures in the actual surfing process, we can try to enter the background management setting interface of the wireless router and find the connection mode setting option to see if the parameter of this option has been set to? Automatic connection, automatic connection after starting disconnection? If it is not correct, you must modify the connection method in time, and finally save it in the background management interface. The parameter modification operation before saving is successful. Finally, restart the wireless router device. I believe this will probably solve the intermittent disconnection of wireless network.
Of course, if the intermittent disconnection cannot be solved through the above settings, we need to check whether there is network virus attack on the local wireless LAN, because once the ARP network is illegally attacked by viruses, intermittent disconnection may also occur; At this time, we might as well open the local connection property setting window in the local workstation system, and then enter the property setting interface of the network card device, where we try to modify the IP address used by the network card to see if there will be intermittent network disconnection failure under the new IP address condition. If wireless network failures continue to occur, we must use professional anti-virus attack tools and software to protect the wireless LAN.
Third, check the connection location to solve the problem of slow Internet access.
When trying wireless access operation, if it is found that the access speed is slow, two troubleshooting operations should be carried out. The first thing we need to check is whether the WEB server we are currently visiting is in a busy working state. Once the target server is in a busy working state, the only thing we can do is to try to avoid the peak hours of surfing the Internet. If the access speed is always slow when accessing the WEB server at any time, it is mostly caused by the weak wireless transmission signal. The main reason for the weak wireless transmission signal is often the improper connection position of wireless router equipment; In order to improve the strength of wireless signal as much as possible, we must put the wireless router equipment in a relatively high place, and ensure that there is no cement wall between the equipment and the workstation, otherwise the transmission of wireless signal will be easily interfered by the outside world, resulting in huge signal attenuation and affecting the access speed of wireless Internet. In addition, I need to remind you that if you use a wireless router device in a local area network, you must ensure that the device is located in the center of all workstations and that each workstation can transmit data quickly.
Fourth, check the connection status and solve the problem of being unable to log in.
The first thing I want to tell you is, what is mentioned here? Unable to log in. Fault? Mainly refers to the inability to log in to the background management interface of the wireless router. There are many reasons why the wireless router cannot log in. We should start with the connection status of the wireless router to see if there is any hardware failure in the equipment at this time. Usually, we can quickly judge whether there is a wireless network failure by observing the signal lights in the control panel of the wireless router. For example, if the power signal light of the wireless router is not on, it is likely that the input voltage of the equipment is abnormal, and then we must replace the new wireless router equipment; If the power signal light is on all the time, it is also an abnormal phenomenon. At this time, we might as well check the broadband cable connected to the equipment and consider reconnecting with other network cables.
After confirming that the wireless router is connected normally, we might as well enter the LAN workstation system and check the network connection currently used to see if the IP address used by the workstation is dynamic or static. If you used a dynamic address before, you can try to modify the workstation IP address to use a static IP address and turn off the network firewall function of the local system. Through the above efforts, if you still can't log in to the wireless router, you can try to modify the settings of IE. When modifying IE settings, you can first open the IE browser window and execute it in turn in the menu bar of this window? Tools? /? Internet options? Command, in the pop-up Internet option setting window, click? Connect? Label, and in the corresponding tab page? Never dial? Be selected; Then click "?" In the tab. Lan settings? Button, and clear all the options in the subsequent settings page, and finally click? Are you sure? Button to end the setting operation of IE. After completing the above settings, try to enter the router address in the address bar of IE browser to connect, and maybe you can log in to the wireless router smoothly.
If the above troubleshooting still can't solve the problem, we can restore all the parameters of the equipment to the factory settings through the Restore button in the control panel of the wireless router, and then reset them. I believe this will probably solve the problem of being unable to log on to the wireless network.
