The reason of signal instability in wireless router

Wireless router signal instability, most of the problem is set up, the following points analysis can help you quickly find the reason:

First, the key to the problem on 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, is estimated to be 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.

Second, the strength of the wireless signal is often not the power of their own equipment to play a major role, the degree of interference between the signal has 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.

Third, the establishment of conflicts 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.

Four, 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.

Five, 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.

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, view the wireless router in the wireless network settings, found that the wireless signal transmission band selected as 13 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.

Eight, because the default Tp-link products will be transmitted through the band 6来 External wireless signal, so many tp-link products have a conflict between the different network of wireless signals using band 6来 transmission, mutual interference affects the intensity of wireless signal, Thus causing the 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.
