Check the wireless network connection line and solve the wireless network failure that only sends but does not receive
When checking the wireless network connection status information, we sometimes see that the wireless network can send information to the outside, but cannot receive information from the outside. This one-way communication method will obviously affect our normal wireless access operations. When we unfortunately encounter the trouble of one-way communication of the wireless network, we can follow the following ideas to check one by one:
First, we need to ensure that the wireless network connection line is in a smooth state. When checking whether the line is in a connected state, we can first open the IE browser and enter the default IP address of the router in the address bar of the pop-up browsing window (this address can usually be found in the router's operating manual), then enter the router login account correctly and open the router's backend management interface; then execute the ping command in the management interface to ping the DNS server address provided by the local Internet service provider. If the target address can be pinged, it means that the line connection between the router device and the Internet service provider is in a smooth state. If the target address cannot be pinged, it means that some parameters inside the router may not be set correctly. At this time, we must 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 execute the ping command in the workstation to ping the IP address used by the router. If the address can be pinged normally, it means that the line connection inside the LAN is also unobstructed. If the IP address used by the router cannot be pinged, then we need to check whether the network parameters used by the local workstation are consistent with the network parameters used by the router, that is, whether their address parameters are in the same network segment. If all the above addresses can be pinged successfully, but the wireless network connection is still in a state of only sending but not receiving, then we might as well focus on checking whether the DNS parameters and gateway parameter settings of the local workstation are correct. After confirming that these parameters are correct, we also need to enter the router background management interface again, find the NAT parameter setting option, and check whether the option is configured correctly; when performing this parameter check operation, we must focus on checking whether there are translation entries for the internal network address in the NAT address translation table. If not, the wireless network failure of only sending but not receiving is mostly caused by improper NAT configuration. At this time, we only need to correctly add the translation entry for the internal network address to the NAT address translation table.
Check the wireless network connection method and solve the wireless network failure caused by intermittent network disconnection
When the local area network is connected to the Internet through a wireless router, if the workstations in the local area network often have the phenomenon of being able to access the Internet normally for a while and then not being able to access the Internet normally, we first need to ensure that the Internet parameters between the workstation and the wireless router must be correct. On this basis, we should focus on checking whether the connection method of the wireless router is set properly. Normally, wireless router devices can generally support three or more connection methods, but by default, most wireless router devices will use the "on-demand connection, automatically connect when there is access to data" connection method. In other words, the wireless router device will automatically detect whether there is a line idle at a certain 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. For this reason, when we often encounter intermittent wireless network disconnection during the actual Internet access process, we can try to enter the wireless router background management setting interface, find the connection mode setting option, and check whether the parameters of this option have been set to "Automatically connect, automatically connect after power-on and disconnection". If it is incorrect, the connection mode must be modified in time, and finally the save operation is executed in the background management interface to successfully save the previous parameter modification operation. Finally, restart the wireless router device. I believe this will most likely solve the intermittent wireless network disconnection problem.
Of course, if the above settings still cannot solve the intermittent network disconnection problem, we need to check whether there is a network * attack in the local wireless LAN, because once the ARP network is attacked by * illegally, intermittent network 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 network card device property setting interface, and try to modify the IP address used by the network card in this interface to see if the intermittent network disconnection problem still occurs under the new IP address conditions. If the wireless network failure continues to occur, we must use professional anti-* attack tool software to protect the wireless LAN.
Check the wireless network connection location and solve the wireless network failure that causes slow Internet access
When trying to access wirelessly, if you find that the access speed is very slow, we should conduct two-way troubleshooting. The first thing we need to check is whether the WEB server we are currently accessing 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 period of Internet access; 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 placement of the connection position of the wireless router device; in order to maximize the strength of the wireless signal, we must place the wireless router device in a relatively high position, and ensure that there are not many cement walls between the device and the workstation, otherwise the transmission of the wireless signal is easily interfered by the outside world, resulting in a huge signal attenuation, thereby affecting the access speed of the wireless Internet. In addition, it is necessary to remind you that if the wireless router device is used in a local area network, then make sure that the device is located in the center of all workstations to ensure that each workstation can transmit data quickly.
Check the wireless network connection status and solve the wireless network failure that cannot log in
First of all, I need to make it clear to everyone that the "failure to log in" mentioned here mainly refers to the inability to log in to the wireless router background management interface. There are many reasons why the wireless router cannot be logged in. We should start with the connection status of the wireless router to check whether the device has a hardware failure at this time. Usually, we can quickly determine whether the device has a hardware wireless network failure by observing the signal light in the wireless router control panel. For example, if the power signal light of the wireless router is not on, it is very likely that the input voltage of the device is abnormal. At this time, we must replace a new wireless router device; if the power signal light is always on, this is also an abnormal phenomenon. At this time, we might as well check the broadband line connected to the device and consider using other network cables to reconnect.
After confirming that the wireless router is connected normally, we may as well enter the LAN workstation system and check the current network connection to see whether the IP address used by the workstation is a dynamic address or a static address. If a dynamic address was used before, we can try to change the workstation IP address to a static IP address and turn off the network firewall function of the local system. Through the above efforts, if we still cannot log in to the wireless router, we can try to modify the IE settings; when modifying the IE settings, you can first open the IE browser window and execute the "Tools"/"Internet Options" command in the menu bar of the window in sequence. In the pop-up Internet Options Settings window, click the "Connection" tab and select "Never dial-up connection" in the corresponding tab page; then click the "LAN Settings" button in the tab page and clear all options in the subsequent settings page, and finally click the "OK" button to end the IE settings. After completing the above settings, try to enter the router address in the IE browser address box to connect, maybe you can successfully log in to the wireless router.
If the above troubleshooting still cannot solve the problem, we can use the restore button in the wireless router control panel to restore all device parameters to factory settings, and then reset them. I believe this will most likely solve the problem of being unable to log into the wireless network.
