Nowadays, society tends to be more and more networked. More and more people use the wireless network to monitor. When using wireless network processes, the wireless network signal often encounters instability and weakness. In fact, there are many factors that cause instability in wireless network signals. The general manager of Shenzhen Lean Technology and Technology Co., Ltd. believes that wireless devices are the main ones. So let us start from the perspective of wireless network equipment, look at the wireless device in the transmission process caused instability.
1. Instability caused by DHCP packets. Experienced users all know that the DHCP service can help us to automatically assign IP addresses of computers in the network. However, in actual use, DHCP can cause network instability. For example, when a lease expires, IP is obtained again but the network is discovered. The other computers are already using the IP address, or the computer and the wireless router frequently negotiate DHCP messages. In fact, these DHCP packets are completely unnecessary. For the average home user, there are not many computers in the network. We can reduce DHCP packets by manually setting network parameters such as IP addresses.
More and more wireless devices, such as wireless monitoring, wireless video surveillance and other wireless monitoring devices. These things are more and more advanced. We must not only understand how to use it, but also understand some knowledge about it. When these wireless video surveillance devices have problems, we understand the source of the problems and know how to solve them. This will not only reduce the trouble, but also let us know more about it.
Second, the wireless router itself is not stable When the wireless router is placed without problems and the wireless network signal is unstable, we must first consider the problem of the wireless router itself. At this time, we can put the notebook close to the wireless router, or take the wireless router near the PC with the wireless network card inserted, and reduce the distance to check the stability of the wireless signal. If the connection speed and signal strength are still not ideal, you need to check the stability from the wireless router. The most common method is to go to the wireless product manufacturer's home page to download the latest patch package or firmware driver. The method of upgrading the drive is particularly effective when the wireless router signal is unstable or the wireless network card is automatically dropped every few minutes.
Third, the wireless network card itself is often the most rug-type search can find the problem, although it seems a bit stupid, but after troubleshooting wireless router, the receiver's wireless network card has undoubtedly become the focus of the suspect. From the wireless network card point of view, the problem is generally due to the following two points:
1, the wireless network card itself drive problem, must use the drive with the disc to install the wireless network card, because the driver is correct and whether it is the version of the drive is the main factor to determine the stability of the wireless network.
2, the wireless network card's own connection speed, we all know that in the wired network when two computers in the network to transmit data, if a computer's network card is set to simplex or transmission speed is 10M, and another computer's network card is duplex Or the transmission speed is 100M. At this moment, two network cards frequently negotiate the connection speed and working mode and cannot transmit or disconnect frequently. The same is true of wireless network cards, so it is recommended that you should choose supporting products when selecting wireless routers and wireless network card products.
Fourth, wireless equipment location is not reasonable General situation Wireless router should be placed in the middle of the room, whether it is from the signal coverage or the transmission speed can get the best results. And there are many corners of the wall in our room, and each corner affects the transmission of wireless signals. Therefore, corners should be avoided when designing wireless networks and equipment placement.
