How much better is wired internet than Wi-Fi?

Question

Computer networks

If we consider the issue within the framework of an FPS shooter (Quake Live, Team Fortress 2, Overwatch), then how critical is the use of Wi-Fi instead of wired Internet? How many milliseconds, let's say, are added to the main ping on average, provided that the distance between the route and the computer is minimal? Or has modern technology obliterated the difference between wired and wireless?

Answer 1

The problem is that the wifi environment is not very stable: you had a ping all day within 10ms, and in the evening everyone came home turned on wifi movies, turned on the microwave - the radio is overloaded and now the ping jumps under 200-300, and sometimes packets are lost . If you need stability, then only the wire.

Answer 2

Pts critical, examples:
1 - Neighbors behind the wall started heating sausages in the microwave and you had a ping of 60 and became 350
2 - Grandfather Vasily cooks his old Muscovite in the yard with electric welding - you have a packet loss of 30%
and so on.
For FPS shooters - only wire.

Answer 3

It is critical to just use the wired version, since it gives the least interference (especially in good shielded cables). And accordingly, the ping is more stable and packet loss can only be due to the fault of the provider or for other external reasons.
But there are too many related factors in WiFi - how far from the signal source, the power of the transmitter and receiver, the presence of obstacles, the number of neighbors who also actively use WiFi, how many devices in total use this WiFi, how many all kinds of devices with electromagnetic radiation nearby (microwaves in that number), weather conditions even influence. Therefore, it is almost impossible to get a stable connection, which means that within the framework of a shooter, you can never be sure that there has not been a sharp jump in ping or a packet loss (which means that your movement could actually happen for the enemy with a delay or the shot did not happen), this can significantly affect the gameplay.

Answer 4

A counter question - why do you think gaming keyboards are only wired? No wireless? The answer is very simple - because the wire provides its own unique signal transmission medium from the mouse to the computer, and the ether - it is one for all and in it one for all the laws of physics apply equally to all , and now there are more and more devices with wifi - it is already in there are children's toys and vibrators :)
