Changes required to use Ethernet instead of Wi-Fi

[Traveller]

I have two Raspberry 3 model B+ feeds sending data via Wi-Fi and I wish to stop the Wi-Fi and use an Ethernet connection.

Can someone advise me please on what changes are required to the Raspberry; thank you

Plugging in a cable and restarting.

Thanks Oblivian....

I therefore assume that there is nothing to be done to disable the wi-fi ? That plugging in the ethernet cable disables the wi-fi ?

Thank you

Thank you

When Network cable is plugged in, both WiFi & Ethernet connections are working and available, but Ethernet (cable) is used as default connection.
If you want to turn off WiFi, give this command. However this is temporary and on reboot, the WiFi will start again.

STOP WiFi

sudo ifconfig wlan0 down

START WiFi

sudo ifconfig wlan0 up

For permanent method, please see this:

You may have to select the Ethernet option from your internet settings on the OS, but it's worth trying just plugging in and restarting too...
