How to use wireless signal to judge and solve router fault

How to troubleshoot the wireless network? How to find out the reason of the wireless network fault through the wireless network signal? The problem with the wireless network is more or less related to the signal.

One, the establishment of conflict caused by abnormal signal, friends home recently set up a wireless network, the use of equipment is Tp-link router, however, the actual use of network transmission speed is not ideal, and the range of signal coverage is very small, and did not reach the ideal transmission distance, The signal strength weakens rapidly after isolating a wall or a room.

Second, after the investigation found that even in the wireless router next to the signal can not achieve the highest, has been unable to work full signal state, into the wireless router settings interface also did not find anything wrong, the device to take home after not found a problem, the signal is very strong, separated from the two rooms can also be normal wireless communication. It doesn't seem to be a problem with the device itself.

Third, the issue of the key to the wireless signal conflict, and again to a friend home and through the network Stumbler Wireless signal Scanning tool around the signal scanning, the results of the author found in the vicinity of friends do have a lot of wireless signals, it is estimated that the neighbor home using wireless router launch. And there are several default SSID numbers in these signals that are tp-link, which is also the product of the Tp-link company and uses the default values.

Four, as a result of the default Tp-link products will be transmitted through the band 6来 External radio signals, so many tp-link products have a conflict between the different network wireless signals are using the band 6来 transmission, mutual interference affects the intensity of wireless signal, resulting in a friend's own wireless signal abnormal fault.

Finally, the author will Tp-link wireless router launched wireless signal using the frequency band to modify the selection of a current network without any equipment used in the band, all problems solved, wireless signal also returned to normal.

Five, wireless signal strength is not a lot of the power of their own equipment to play a major role, the interference between the degree of signal often play a large role. Therefore, it is the best way to improve the signal intensity by reasonably modifying the radio signal transmitting frequency band and avoiding the default frequency bands as far as possible.

Six, there is also a situation is the wireless device with a wireless network card, however, in the use of the process has not been able to successfully connect the wireless networks in the home, the specific symptoms are clearly wireless network, but is unable to search the wireless network signal, the system shows "unable to connect" error prompts.

Seven, check the notebook to ensure that the wireless card switch is on, but the wireless card is still not on the light. Next scan the current wireless network with another notebook to connect smoothly.

Friend Notebook hardware also no problem, in the BIOS corresponding to the wireless card parameters are also open, repeatedly remove and reinstall the wireless network card driver, using the system with the system CD-ROM, still can not solve the problem.

Eight, the wireless router to view the wireless network settings, found that the wireless signal transmission band selected 13 frequency band, and the notebook itself with the Intel wireless network card only 11 channels, which caused the Intel wireless network card can not connect to the wireless router fault. After modification of the launch frequency band problem solved.

Because Intel's wireless network card has only 11 channels, and many routers have 13 channels, if the router is set on the 12th or 13th channel, the Intel wireless network card is unable to connect to the wireless router, showing that wireless networks can not be found, In this case, you can change the router's channel to any of the 1th to 11th.
