Analysis of weak wireless network signal

The setting of wireless networks has always been the focus of our research. For the reasons, we have provided a lot of analysis below, which will help us to learn more. The actual use of wireless devices is often disappointing to consumers. In actual use, the reasons for unstable wireless network signals due to various reasons also need to be considered comprehensively. In actual use, we often find that the coverage of wireless signals is not as good as the product description, which is disappointing. In actual use, the signal may be affected by some objective factors such as the environment, which is unavoidable. Of course, we are not helpless in terms of signal attenuation. We can use some techniques to minimize signal attenuation.

1. Reasonably place the location of the Wireless Router

Since wireless signals pass through obstacles, especially after metal, the signal will be greatly reduced. In our home house, there are many reinforced concrete walls, so when we place wireless routers, we should make the signal as few as possible to cross the walls.

We usually seldom access the internet in the kitchen or dining room, while the study and bedroom are places where we often access the Internet, so when we choose the location of the wireless router, you can choose to stay away from the kitchen and dining room, and try to stay close to the study and bedroom.

The exterior wall of the study is an ideal location for wireless routers, which enables the living room, study, master bedroom, and second bedroom to have a good wireless signal. Of course, the structures of different families are different, and you should decide based on the actual situation. Generally, clients of wireless network interfaces can detect the signal strength. You can view the signal strength in the room using your laptop to select an optimal placement point. You can also install the Network Stumbler software to detect the signal strength.

2. Modify the signal channel to reduce interference

We can see the wireless channel options in the wireless router configuration interface. In general, there are 11 wireless channels in 54M, which are from Channel 1 to channel 11 in sequence. When multiple wireless signals use the same wireless signal channel, signal interference occurs.

After purchasing a wireless router, many users do not modify the wireless signal channel. In this way, all users use the channel in the default configuration of the router, which is prone to channel interference. If nearby neighbors use the same channel as ours, our wireless signals will be affected.

We can also use the Network Stumbler software for scanning to see which wireless signals exist nearby and which channel is used. Then modify our own wireless channels to avoid duplication with other channels.

In addition, you should note that the signal of a channel will interfere with two adjacent channels at the same time, that is, the signal of Channel 6 will affect Channel 5 and channel 7, therefore, when setting a wireless channel, we should try to keep our channel above two other signal channels.

In addition, many household appliances will also cause electromagnetic interference to wireless network signals when working, so the placement of wireless routers should also be as far away as possible.

3. Extended antenna enhancement Signal

Because the antenna gain size directly affects the signal transmission strength and receiving capability, some routers on the market use detachable antennas, therefore, replacing a high-gain antenna with a wireless router is the most direct method to enhance the signal. The gain antenna market has many advantages and the price is also low. However, it is worth noting that when buying an omnidirectional antenna, you should check whether it is an omnidirectional antenna. Otherwise, only one direction can be used to transmit wireless signals.

In addition, we can expand the antenna of the wireless network card. However, the antenna of the wireless network card is generally not detachable, And it is troublesome to replace it. In fact, many small items in life can enhance wireless network signals. There are also a lot of DIY wireless network gain antenna methods on the network, such as using milk powder cans, mosquito coils, and spoons. If you are interested, try again.

Summary:

The techniques mentioned in this Article can improve the signal strength to a certain extent. However, the actual transmit power of the router itself is the most critical. Of course, readers do not have to worry about poor use at home after purchasing a wireless router. Currently, the standard rate of mainstream wireless routers is 54 Mbps, while the bandwidth in our home is usually 2 M for ADSL, while the shared bandwidth of residential bandwidth is generally 10 M, even if the signal strength fails to reach 100%, the transmission rate can meet the Internet access needs of general household users.
