Why wireless Internet is faster than wired

That's a big deal. It's just a feeling in my own heart.

The reason why the same router is wireless faster than wired: When the network cable socket connector has a poor contact problem, open the web page, and the network delay will increase, which will cause the wireless to be faster than the wired.

Under normal circumstances, it is theoretically or practically silly to be silly which should be wired faster than wireless.

In the process of wireless signal transmission, there is an extra hand-auspicious code in the middle, that is, the data packet signal, to be modulated as a radio wave wifi signal, and may be affected by various interferences during the transmission process, such as through the wall, etc., and the receiving equipment needs to demodulate and restore the data packet signal before it can be used, and the signal will have a certain loss after conversion back and forth.

In addition to the resistance in the line, that is, the impedance, the wired mode will produce some line loss problems, but the signal quality and transmission efficiency are much more stable than the wireless mode, and the wired distance is usually very short, so the loss is low.

If the wireless transmission is much slower than the wired transmission, the possible reason is: the wireless network card signal is not good or someone is rubbing the network.

1. The signal of the wireless network card is not good.

If it is a wireless transmission, there will be a problem of signal attenuation and hotspot signal strength caused by a barrier rock. The router transmits very limited power and can only receive data normally in the room. If the partition wall or the interval is far away, the transmission speed will be slow due to poor signal.

In contrast, the attenuation of the network cable is much weaker.

2. Someone rubbed the net.

Thanks to the relative openness of the wireless network, people near the wireless network hotspot can use the wireless network to access the Internet if they crack the password. The network bandwidth is occupied, which leads to the situation of getting stuck in the Internet. Wired networks, on the other hand, do not exist.

A network cable is no faster than wifi.

The amount of network speed is determined by the broadband line and the router itself, therefore, whether your computer is connected to wifi or directly connected with a network cable, the network speed itself will not change, that is to say, the network speed of wifi and network cable direct connection is the same, however, when we use wifi, we find that sometimes, wifi network speed is much worse than that of network cable direct connection, why is this?

The difference between the two. WiFi connection greatly improves the convenience of the device to go online, after all, not all Zhao Ying Zen has a network cable interface, but although the network speed is determined by the home broadband line and router, theoretically wifi and network cable direct connection of the network speed is the same, but due to wifi There are too many interference factors, so the network speed is indeed not as fast as the network cable direct connection.

Signal interference. Most of the wifi routers commonly used in our homes are frequency bands, and this frequency band is very strong because most routers are in use, after all, every household now has at least one router.

Therefore, if there is too much wifi in the same band around you, then the impact on the wifi signal is very large. In addition, the location of the router is also a factor that affects the wifi signal, such as a mobile phone, Bluetooth songbu device, microwave oven, etc., next to the router, which will cause interference to the wireless signal.
