Does direct ethernet affect wifi?

Question

Computer networks

I have a WI-FI modem hanging, and when I need to download large files, movies, games, I connect an Ethernet cable to my laptop, because it is much faster, so does what I download through this cable affect the wifi speed?

Answer 1

If you have a wifi router connected via ethernet, for example, to a provider, and you connect to it via ethernet as needed, then of course it can affect, because. the bottleneck can be the channel to the provider (the speed on which is usually limited), and even the router itself.
If you have some other connection scheme, then describe it in more detail so that it is clear what is connected where.

Answer 2

It depends on what you mean by "wifi speed": this does not directly affect the wireless connection between your devices, while the Internet connection is very much affected if there is only one connection to the provider. However, you will more or less feel it only if you use the channel to the maximum, i.e. if you have a channel of 100 Mbps and download a movie through a cable at the same speed, then naturally nothing remains on wifi.

Answer 3

Yes. Wi-Fi is the same network, just without wires.
The source of the Internet - one - is a router.
The speed is shared by all consumers, regardless of whether it is Wi-Fi or a wired connection.

Answer 4

Of course, it affects the speed of the Internet via wifi. If the Internet channel is, say, 100 Mbps, and the download occurs at a speed of 95 Mbps over ethernet, 5 Mbps remains on wifi. If you want to download, and at the same time not interfere with others, configure the QoS router
