Troubleshooting of common wireless network faults

Wireless Internet access through wireless routers has become increasingly popular; however, in the process of wireless Internet access, we often encounter a variety of network failures, these network failures seriously affect the normal efficiency of the Internet. In fact, as long as we in peacetime to strengthen the investigation, timely summary of a variety of common network troubleshooting experience, I believe that in the future we will be able to become a management of wireless network expert!

Troubleshoot connection lines to solve the problem

When viewing wireless network connection status information, we sometimes see that wireless networks can send information externally, but cannot receive information from outside, a one-way communication that obviously affects our normal wireless access operation. When unfortunately encountered in the wireless network one-way communication problems, we can follow the following ideas for one by one:

First of all to ensure that the wireless network connection lines in a smooth state. When you see whether the line is connected, we can first open IE browser, and in the pop-up browser window address bar to enter the default IP address used by the router (this address can generally be found from the router's operating instructions), and then correctly enter the router login account, open the router's background management interface; Then ping in the admin interface to ping the DNS server address provided by the local Internet service provider, and if the destination address can be ping, it indicates that the line connection between the router device and the Internet service provider is unblocked. If the target address cannot be ping, it means that some of the parameters inside the router may not be set correctly, then we have to check the configuration parameters inside the router.

In the confirmation of the router internal configuration parameters are correct, we can find a network in the LAN properly configured, the normal access to the workstation, and the workstation in the ping command to ping the IP address used by the router, if the address can be normal ping, That means that the LAN internal wiring is also unblocked, if the IP address used by the router, it is necessary to check whether the network parameters used by the local workstation are in line 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 smoothly ping, however, the wireless network connection is still in the status of only, then we may want to focus on the local workstation DNS parameters and gateway parameter settings are correct, after confirming that these parameters are correct, we also need to enter the Router backend management interface again, To find the parameter setting options for NAT, and check that the option is configured correctly, and when this parameter check is done, we will focus on checking that the NAT address translation table has a translation entry for the internal network address, and if not, then the wireless network connection will only fail due to Due to improper NAT configuration, we can simply add the translation entries for the Internal network address to the NAT address translation table.

Troubleshoot intermittent network failures by troubleshooting connection modes

In the case where the local LAN is connected to the Internet through the wireless router, if the workstation in the local area network often appears for a while to be able to normally surf the internet, while the malfunction of the internet is not normal, we first need to ensure that the network parameters between the workstation and the wireless router must be correct, On this basis should be focused on checking the wireless router connection is properly set. Typically, a wireless router device typically supports three or more connection types, however, by default, most wireless router devices use the "on-demand connection, automatic connection when there is access to data", in other words, every time the wireless router device automatically detects whether there is a line unloaded at this point, If the device does not detect any data interaction in the line after it is successfully connected, it will automatically disconnect the connected wireless connection line. To this end, when we are actually surfing the internet, often encountered intermittent network failure phenomenon, we can try to enter the wireless router background Management settings interface, find the connection mode setting options, and see if the parameters of this option has been set to "automatic connection, in the boot and disconnect after automatic connection", if not correct , must be in a timely manner to modify the connection, and finally in the background management interface to perform the save operation, the previous parameter modification operation to save success, and finally restart the wireless router equipment, I believe this can solve the wireless network intermittent fault.

Of course, through the above settings still can not solve intermittent network failure phenomenon, we need to check whether the local wireless LAN network virus attacks, because once the ARP network was illegally attacked by the virus, there may be intermittent fault network; At this point we might as well be in the local workstation system, Open the Local Area Connection Properties Settings window, and then go to the network Card device properties settings interface, in the interface to try to modify the IP address used by the network card, to see if the new IP address conditions, intermittent break network failure can also appear, if the fault continues to appear, We must use the professional anti-virus attack tool software to protect the wireless LAN.

Troubleshoot the connection location to solve the problem of Internet slow

When attempting a wireless access operation, if it is found that the access rate is very slow, we should perform two troubleshooting actions. The first thing to check is whether our current Web server is busy working, and once the target server is busy working, the only thing we can do is try to avoid the peak of the Internet; If you visit the Web server at any time, the speed is slow. That's mostly because the wireless transmission signal is relatively weak. The main cause of the weak wireless transmission signal, often is the wireless router equipment connection position improper; In order to maximize the strength of the wireless signal, we must put the wireless router equipment in a relatively high place, and to ensure that the device and the workstation can not have more cement walls, Otherwise, wireless signal transmission is very vulnerable to external interference, resulting in large signal attenuation, which affects the speed of wireless Internet access. In addition, it is important to remind you that if the wireless router device is used in a local area network, make sure that the device is in the center of all workstations and that each workstation can transmit data quickly.
