I have a Raspberry Pi Zero W v 1.1, to which I don't have any way to connect display adapter, therefore I communicate with it through ssh. It is connected to one isolated wifi network(with no internet access) for this connection. I need to connect it to another wifi at the same time from a different wifi adapter - connection is allowed only from certain Mac address, so I must use it - in order to have internet access. From the information I understood from here:

https://raspberrypi.stackexchange.com/a/37921

That on older raspbian versions connection was as easy as modifying the interfaces file with wpa-conf parameter. However, on new versions all things are resolved by dhcpcd.conf, where I can't find direct equivalent of this functionality. Is there any way to do this in this version, or should I just go back to old way of defining it?

You can create different wpa_supplicant files for each interface.

If you search my Answer on setting up network “Use different wpa_supplicant files “ explains.

Create a file named wpa_supplicant-"$interface".conf in /etc/wpa_supplicant/ e.g. wpa_supplicant-wlan0.conf will only be used by wlan0.

It is a good idea to enable Predictable Network Interface Names which will create an interface based on MAC, to ensure that only the desired interface is used.

  • I've read the answer in detail, seems like I didn't notice the "Use different wpa_supplicant files" section. It works flawlessly after following instructions. Thanks for your time :) – hypixus Jul 11 at 23:18
