What you don't know:
Most broadband operators receive the most complaints from customers every day. The speed is very slow. According to authoritative statistics, the speed of WiFi used by consumers on the market is usually only about half of the bandwidth limit of their routers.
The following six factors affect the speed of WIFI:
1. WiFi Signal Congestion The user is connected to the WIFI network in the same way as listening to a radio station. WIFI only provides a fixed frequency wireless band to the user.
New Zealand’s Steve Biddle, a research engineer with a wireless hotspot, said in an article: “If you live in an apartment with hundreds of wireless network devices, then This is almost the worst WiFi usage environment."
Even if the WiFi signal bar on the wireless terminal is full, it will still be very slow to use. In fact, including mobile phones, wireless phones, microwave shanghai, Bluetooth devices and even wireless baby monitoring devices may affect the WiFi signal quality.
2. WIFI cannot send and receive data at the same time. Many people may not know that WiFi signals cannot send and receive data at the same time. Therefore, when using a WIFI network, there will be more data delays, and it is a normal phenomenon. The use of the same WiFi channel at the same time by many people will also greatly affect the WiFi signal strength.
In fact, your router can usually use hundreds of WiFi channels. At present, most people adjust the option of router channel selection to the “automatic†mode, so they do not play the advantages of hundreds of WIFI channels on the router at all, leading to users. All use the 2.4GHz frequency channel, which is already blocked, by "default".
In addition, if you are in an area with sufficient network signal, your router will continue to search for the best network channel, which will also cause network delays, and this is not a problem that broadband operators can solve.
3. Comprehension of advantages and disadvantages In the final analysis, the wireless network must rely on the support of the wired network. Regardless of how much advancement the WiFi technology will make in the future, the wireless connection method will hardly exceed the wired Internet access model.
Therefore, WiFi will not completely replace the wired Internet connection, it is just a more convenient networking solution.
4. Quiet silent background tasks If all of the above factors have been eliminated and the WiFi speed is still not improved, check if your software is automatically synchronizing data and photos. In fact, applications such as Steam, Netflix and BitTorrent, which are the world's largest integrated digital distribution platforms, will transfer files in the background, which will greatly affect users' WiFi speed. Because the background automatically initiates the transfer task, many users simply do not find that they are working at all times.
5. Router Location The location of the wireless router has a very large influence on the signal strength. The WIFI signal camera introduced the other day can capture the signal strength of WIFI. We can intuitively see that the WIFI signal is indeed affected by the environment, for example, if the router is placed on a concrete wall, its signal strength will be greatly reduced. The best location for the router is the ceiling in the middle of the room (of course, many consumers do not have such conditions), in short, the best choice is to place the router in an open, signal-diffusing area.
6. Connection device differences Different devices have different processing speeds, and of course WiFi connection speed is also very much related to the connection device's information processing speed. The connection speed of the same device will be almost the same, but the connection of different devices. Speed ​​will easily show the gap.
