Which network speed is faster when plugging in a network cable or connecting to WiFi on a wireless router

1.The difference between wireless and wired connections.

There are many conditions for using a wired network, and the device must have a network cable interface, and additional network cables are also required. And wireless connection is different. As long as wireless WiFi is set up, mobile terminals such as computers/phones/tablets can directly connect to WiFi for internet access, greatly improving convenience.
But when it comes to network speed, it actually depends on the router itself and has nothing to do with wired and wireless. That is to say, under the same router, theoretically the speed of wired and wireless is the same. But why is it faster for us to plug in network cables?

2 Signal interference
The signal interference of wireless WiFi is easy to understand. The Wireless Router's WiFi signal needs to work in the 2.4GHz frequency band, and devices such as Bluetooth and microwave ovens that also work in this frequency band at home can cause interference to the wireless signal.

In addition, there may be interference between different wireless routers. With the popularization of WiFi coverage, a random search can reveal a large amount of WiFi, which can also affect the signal of WiFi. Wifi 5 Wireless Router
If you plug in the network cable, this problem basically disappears. Currently, most of the network cables on the market are twisted pair structures, which have strong anti-interference ability. WiFi 6 Wireless Router

Taking the Class 6 gigabit network cable of Green Link as an example, four sets of twisted pairs are separated by a cross skeleton, and each two wires are twisted together at a certain density. The radio waves radiated by each wire during transmission are offset by the radio waves emitted by the other wire, with a transmission rate of up to 1Gbps, which is much more handsome than wireless networks!

3.Signal attenuation
Taking wireless WiFi as an example, when connecting to WiFi, we often find this problem: when going to a room far from the router, the WiFi signal will be particularly weak, and if the router is placed in a corner, the entire internet experience is simply not good. For plugging in network cables, this problem does not exist.
Taking the above gigabit network cable as an example, with cross skeleton isolation and 8-core twisted pair protection, theoretically speaking, it can also be connected to the internet at a distance of 100 meters and can adapt to more complex network environments.

4. How to choose between plugging in a network cable and connecting to WiFi? 4G CAT6 CPE
Since wired networks are faster, do we have to abandon wireless networks? Of course not.
Compared to wired networks, WiFi has a longer and unstable latency. If you are not sensitive to latency, such as using your phone to browse web pages or chat on WeChat, just connect to WiFi and there is no need to have a wired network.
But if there is a high demand for real-time performance and frequent interaction, it is better to connect to a wired network, otherwise it is not good to get stuck or even drop the line while playing the game.

5. How can devices without cable interfaces connect to a limited network?
Wired networks are indeed faster, but how can I connect a laptop without a cable interface? There should be a USB3.0 gigabit network card here, as shown in just one image.

As shown in the picture, one end is connected to the USB port of the computer, and the other end is plugged in normally. Your laptop can also enjoy wired network.
