Which is faster, wireless network card or network cable?
Many friends’ computers are connected to network cables, and their mobile phones are connected to WiFi. Under the same router, which one has faster network speed? Without taking into account the performance differences between computers and mobile devices, what are the differences between the two connection methods? Which one is faster when connecting wired and WiFi under the same router?
#1 For connecting a network cable, the device must have a network cable interface, commonly known as a network port. (Recommended learning: PHP video tutorial)
You can only use the network by connecting to the network port! For wireless WiFi, you only need to correctly connect the optical modem network port, configure the router and computer, TVs, mobile phones, tablets and other mobile terminals can connect to WiFi as long as they have wireless network cards! Compared with wired ones, wireless WiFi is more flexible and convenient!
The network speed is determined by the speed of broadband at home and the optical modem and router. It has nothing to do with wired and WiFi! However, WiFi will be affected by external relationships, causing the network speed to drop!
2. Differences in signal interference;
Mostly, when everyone surfs the Internet through WiFi, they use wireless waves in the 2.4GHZ frequency band. We The surrounding models in the same frequency band have a higher number of transmitters and receivers, which can directly cause our WiFi network speed to drop and make our experience worse!
Devices that can directly affect us include mobile phones, wireless Bluetooth headsets, and microwave ovens. Other electrical appliances can affect WiFi! The routers around us can also affect our routers.
Compared with network cables, electromagnetic waves will not cause problems. Network cables are relatively insulated and have an outer sheath to protect them from interference! It can resist electromagnetic interference very well!
3. The difference in signal attenuation;
For WiFi, when encountering load-bearing walls and obstacles, the signal will be weakened, and it will be reflected when encountering metal! When we are far away from the router, it will also affect the WiFi experience. The electromagnetic waves emitted by routers with different powers have different distances!
It is recommended that you place the router in an open or high position, which can effectively reduce the obstruction of obstacles. If the room is larger and is placed in the center of the room, this can effectively reduce the WiFi dead zone. !
4. When choosing a network cable;
Try to choose the length of the network cable below 50 meters. If the network cable is too long and the loss is high, it will affect the network transmission delay, and the computer will be slower and our network speed will be slower. It will become stuck and unstable! When purchasing network cables, purchase them from regular stores. When purchasing, you can fold the network cable to see its softness. If the network cable is soft, it means that the copper wire of the network cable is thin and the quality is not very good. If the network cable is harder, it means the copper wire is thicker, and the quality of the network cable is better! You can ask when purchasing. Be sure to buy Category 5e or above network cables. Such network cables can transmit Gigabit! While ensuring the quality of the network cables, when we install, the network cable layout should be as simple and neat as possible, and do not get entangled or knotted! Only in this way can the transmission be good!
5. When purchasing a router,
we must choose a regular brand, and the wired network port in the parameters must support Gigabit transmission. If the router we purchase does not support Gigabit transmission, the router network port MB, no matter how fast the internet speed we apply for can only reach 100 MB. At the same time, WiFi must also support Gigabit, so as to achieve the transmission with the highest WiFi speed! When connecting to WiFi Energizer, choose to connect to the 5GHz band. The 5ghz transmission rate is higher than 2.4ghz!
6. How to choose between wired and wireless WiFi
We can use WiFi when the actual content is low, such as chatting on WeChat, online shopping, and watching videos. WiFi can satisfy us. normal needs! It is recommended to use a wired network when we have high substantive requirements. For example, for relatively frequent interactions and large-scale online games, we can use wired networks!
In fact, the speed of wired and wireless depends on the speed of the broadband itself and the environmental equipment. If you install the router properly, set it up professionally. There is not much difference between wireless and wired speeds.
