Super practical! Teach you four tips for improving WiFi performance

Nowadays, WiFi has been fully integrated into the modern home, and users can enjoy a beautiful and convenient wireless life by deploying a small home wireless router. However, this "beautiful" experience is supported by a powerful wireless network. If the wireless signal coverage in the user's home is not good and the wireless transmission rate is slow, then this wireless network will only add to your life. . At this time, many users will choose to replace the wireless router to solve the problem. In fact, as long as you pay attention to the following small details, you may not need to change the wireless router in your home, it can also enhance the wireless application experience in your home!

1, reduce co-channel interference

With the rapid development of wireless technology, there are more and more wireless devices in our home. What game consoles (wireless controllers), cordless phones, Bluetooth products, wireless mouse and keyboard, and wireless headsets have become standard equipment for modern users. . But I wonder if you are aware that when these wireless products are used together with your wireless router, your wireless network will experience slower network speeds, frequent dropped calls, and even disconnected networks.

In fact, this is the problem caused by "co-channel interference", because these wireless products work in the public wireless band of 2.4GHz, but the total capacity of the 2.4GHz channel is limited, so when multiple 2.4G wireless devices are used together When there is a "crash" situation.

The solution is also very simple. Try to avoid using these wireless devices at the same time (especially cordless phones), or to maximize the distance between these devices, so that the WiFi network performance in your home will be significantly improved. (PS: Of course, if you can turn off these same-frequency devices, the effect will be even better!)

In addition, there is a special point to note that "co-channel interference" is not only from wireless products such as cordless phones and Bluetooth. Mutual interference between wireless routers also affects the performance of WiFi. For example, neighbors around your home have built their own wireless networks, so your home WiFi will be affected.

In this case, you have two solutions to choose from. First, modify the channel of the wireless router in your home. Choose one, one, six, and one, and which channel is the least occupied. The application experience is optimal. Second, with the neighbors around, we have lowered the wireless transmit power of the wireless routers in the home, thus reducing mutual interference. (PS: To be honest, the feasibility of the second point is very low, but the effect is the most ideal..)

2, adjust the wireless router location

WiFi is very susceptible to interference due to its natural physique, especially when facing walls (bearing walls) and metal objects, which will seriously affect wireless performance. So if you put your home's wireless router in a corner or on a metal shelf, the wireless application experience will naturally be poor. (PS: WiFi is less affected when facing wood, plaster and glass)

Considering that most of the current home wireless routers use 3dBi or 5dBi antennas, the wireless signal coverage is close to spherical, so it is ideal to place the wireless router at the center of the home. Of course, the premise is that there is no wall or metal barrier around!

3. Encrypt the wireless network

Encrypting the wireless network is already a common problem. However, there are still a small number of users who have not encrypted the wireless network in their homes. As a result, there will be more neighbors around the network, and the wireless application experience will naturally deteriorate. More dangerously, if the administrator account of your wireless router is not modified, then the ulterior neighbor can completely control your wireless router, and lightly limit the speed of your wireless application, affecting your wireless application experience. , then modify your DNS, steal your important data information, and ultimately lead to property damage.

In summary, encrypting the wireless network in the home is a work that users must do when setting up a home wireless network. In addition, remember to change the administrator password. Of course, if you can spend some time, complete the IP. +MAC binding, then the most ideal.

4, test the speed of broadband in the home

Today, the broadband speed of most households in China is concentrated between 4-20 Mbps, but some broadband operators claim that the broadband rate is significantly different from the actual application rate, especially during the peak period of the Internet, the downlink speed may drop to 100 KB. /s below, this will make some users mistakenly think that the wireless network in the home is not strong. In fact, the actual wireless transmission rate of the mainstream 11n (300M) wireless router is usually up to 50Mbps, and even the old 11g (54M) wireless router, the actual wireless transmission rate can usually reach 20Mbps, which can match most current families. Export bandwidth.

Therefore, when the user finds that the wireless Internet speed becomes very slow, it is possible to connect to the router through the network cable (or directly connect to the ADSL cat), and then measure (recommended to test through the speed.test website) the actual rate of the broadband network in the home, so that Wrongly blame the wireless router!
