How to improve the stability of wireless network

The so-called stability of the wireless network? That is, the signal should be continuous good, the intensity of the signal should be kept unchanged, even if the weak signal can not appear a weak one will not be a good phenomenon. There are many factors that influence the stability and connection speed of wireless signal in practical application.

　First, avoid frequency band interference:

Band: That is, "Channel" is also called the channel, the wireless signal as the transmission media data signal transmission channel. ieee802.11b/g work in the 2.4~2.4835ghz band (China Standard), these bands are divided into 11 or 13 channels. We choose a band when we release the wireless network, in theory, too much Wi-Fi in the same band can seriously affect the strength of the signal, which means that if your home uses the same wireless signal band as other wireless signals, then some two wireless networks will be affected. Besides There are interference sources near the wireless router, such as microwave ovens, mobile phones, Bluetooth devices, wireless speakers, and so on, they will interfere with the normal use of wireless routers. In particular, part of the digital cordless phone use of 2.4GHz band, so that when the network is unstable through the wireless router to replace a signal transmission band is a good way.

Set the method as shown in the following illustration:

▲ Frequency Bands Division

As can be seen from the above figure, this router can simultaneously provide 2.4ghz/5ghz dual-band wireless signal!5ghz Advantage is the same network environment, 5GHZ band interference less, wireless rate is higher.

　Second, to stabilize the spin down

You may encounter such a situation: because of the convenience of wireless network, many families use wireless routers, more and less cable routers, because the same band of wireless network will interfere with each other, so 13 of the band is not big enough for home, how to solve this problem? The General wireless router will have the function of automatically selecting frequency bands, Let the router automatically select the most appropriate channel. However, if the router does not support this feature, the workaround is simple enough to reduce the wireless router's operating mode from 802.11n to 802.11g or from 802.11g to 802.11b. Although the speed is reduced, but it brings stability benefits, so to a certain extent reduce the speed of transmission can make our wireless network more stable. As shown in the following illustration:

▲ Spin Down

This figure is shown at speed, and the truth is the same!

　　Iii. reducing the use of DHCP

Users who have used DHCP know that every time a client communicates with a DHCP server, four packets are exchanged and each packet is a broadcast packet. If you renew an IP address conflict, DHCP information is frequently negotiated between the user's computer and the wireless router. is bound to have a certain impact on the network. Therefore, if the number of computers in the home user is not large, DHCP function can not, by manually set the IP address network parameters such as the method to reduce the DHCP packet. As shown in the following illustration:

▲ Disable DHCP

Setting the method is also very simple, just disable the DHCP feature. But there are also some routers that turn off this service by default. If your home wireless network often encounters signal instability, try the above methods.
