In actual use, we often find that the coverage of wireless signals is not as good as the product description, which is disappointing.
Because in the actual use, the signal will be affected by the environment and other objective factors and attenuation, which is inevitable.
Of course, for signal attenuation, we are not helpless, in use, we can use some techniques to minimize signal attenuation as far as possible.
1. Reasonable placement of wireless routers.
Because the wireless signal attenuates greatly after crossing the obstacle, especially after passing through the metal.
In our family's house, there are many reinforced concrete walls, so when we put wireless routers, we should make the signal pass through the walls as little as possible.
We rarely surf the Internet in the kitchen or dining room, and the study and bedroom are the places where we often surf the Internet, so when we choose the location of the wireless router, we can choose to be far away from the kitchen and dining room. and get as close to the study and bedroom as possible.
The outer wall of the study is an ideal location for wireless routers, so that the living room, study, master bedroom and secondary bedroom all have a good wireless signal.
Of course, different family structures are different, and we should depend on the specific circumstances.
Generally speaking, the client of the wireless network card has the ability to detect the signal strength, so we take the notebook to check the signal strength all over the room, so as to choose the best placement point.
In addition, Network Stumbler software can be installed to detect the strength of the signal.
Second, modify the signal channel to reduce interference.
We will see the options for wireless channels in the configuration interface of the wireless router.
Generally speaking, there are 11 wireless channels of 54m, followed by channel 1 to channel 11.
Signal interference occurs when multiple wireless signals are using the same wireless signal channel.
Many users do not modify the wireless signal channel after buying a wireless router, so that everyone uses the channel when the router is configured by default, so it is easy to cause channel interference.
If a neighbor nearby uses the same channel as ours, then both of our wireless signals will be affected.
We can also use Network Stumbler software to scan to see what wireless signals are nearby and which channel is used.
Then modify our own wireless channel to avoid duplication with other channels.
In addition, we should pay attention to that the signal of one channel will interfere with the two adjacent channels at the same time, that is, the signal of channel 6 will affect channel 5 and channel 7, so when we set up a wireless channel, you should try to make your channel more than two away from other signal channels.
In addition, many household appliances will also cause electromagnetic interference to the wireless network at work, so the placement of wireless routers should also be as far away from these appliances as possible.
III. Extended antenna enhanced signal.
Because the antenna gain directly affects the transmitting strength and receiving ability of the signal, and the antennas of some routers in the market adopt detachable design, so replacing a high-gain antenna for the wireless router is the most direct way to enhance the signal.
There are many gain antennas on the market, and the price is also cheap.
However, it is worth noting that when purchasing, you should ask if it is an omni-directional antenna, otherwise the use of directional antennas can only transmit wireless signals in one direction.
In addition, we can also expand the antenna of the wireless network card, but the antenna of the wireless network card is generally undetachable and troublesome to ｒｅｐｌａｃｅ.
In fact, many small items in life can enhance the wireless network signal.
There are also many DIY wireless network gain antennas on the network, such as the use of milk powder cans, mosquito incense trays, leaky spoons, etc., interested netizens may wish to try.
