Setting up Ethernet - is the WLAN signal then off?

Is perhaps a somewhat strange question but can't find anything on the network: if I connect my laptop to the router with an Ethernet cable, is the WLAN signal still active?

When can I do to use only the ethernet connection?

Usually there's a corresponding option in the web interface of the router to activate / deactivate WLAN. If you could say which model it is, I would be happy to explain it to you in detail if you have any questions.

No, notebooks should then automatically switch to cables, as this is more stable

WLAN from the router remains activated, of course

Well, one is "wireless" and the other is not.

Router remains active.

If you plug the cable into your laptop and everything works, your laptop should automatically connect to the Internet via the cable. The Wi-Fi sign will then be replaced by another sign.

The WLAN from the router also continues to work and can also be used for other devices.

Your laptop then usually no longer uses the Wi-Fi but the cable connection

Thank you, Vodafone is the WLAN cable router (DOCSIS-3.1 cable modem and WLAN in one device)

I think I have misunderstood something, do you want to completely deactivate your WLAN or was your question whether your laptop automatically dials in via the cable what you put into it and no longer via the WLAN?

@ Christoph34212 I would like to completely deactivate my WLAN and only use the Ethernet connection. If that is possible at all.

Only for one device or for all devices in the network?

@ Christoph34212 I would mainly want to use a laptop with the Ethernet connection, but also a cell phone and a tablet (from time to time).

In most cases, wired connection is preferred as long as it is configured correctly, but Wi-Fi remains active. This is helpful, for example, if you want to work in 2 different networks. If you only have one network, it is of course pointless, but as I said, you don't really have to worry about it.

Then you don't have to do anything else. Your laptop would have to connect via the Ethernet cable as standard as soon as it is plugged in. If you do not want the laptop to go over the WLAN when no cable is connected, you can do the following. In fact, it makes no sense to prevent this. Nevertheless, I explain briefly how to do it (Windows 10 if another operating system please comment):

Open the settings
Click the "Network and Internet" button
Click the "Wi-Fi" category on the left
In the main section of the window, click "Manage Known Networks"
Select your "home WLAN" from the list of WLAN SSIDs listed
Then just click "Don't Save"

Now your laptop will no longer dial into the WLAN.
