Yes, I am aware that similar questions have been asked before on this StackExchange but almost all of those are old and don't seem to be working for me.

After googling around I found that things have been changed ever since rasipbian moved to NetworkManager to manage the network stuff instead of good old ifup/ifdown.

I've also tried to navigate through the documentation of NetworkManager but to no avail.

I just want my pi to have simultaneous access to 2 networks:

  • Using the ethernet wire.
  • Using the onboard WiFi.

Both these connections must work at the same time so that if I host any application to ip, I can access that application from either of the network's devices by using the corresponding IP of pi on that network.

Let me know if I need to be more specific about somethings. :)


  • Raspbian has NOT moved to NetworkManager! See How to set up networking/WiFi. I see no question here. – Milliways Aug 22 at 1:32
  • Yes, I found too many os version specific network things out of date before I started to learn. I am waiting for Rpi4B and buster to settle down. – tlfong01 Aug 22 at 1:33
  • @Milliways That answer doesn't tell me anything about how to set up simultaneous access to both ethernet and wifi :/ – Curious66 Aug 22 at 1:39

    If fact the answer does - it tells you how to do most things in dhcpcd; it may not answer what you want to do, but it is unclear what this is - more detail needed. What does "if I host any application to port" mean? – Milliways Aug 22 at 1:42
  • @Milliways My bad, I meant to say IP, not the port. Sorry about that – Curious66 Aug 22 at 1:54

This solved my problems or is this just my setup?

With a prebuilt custom version of Raspbian Buster on Pi 3 the dhclient was a problem interfering with dhcpcd so first had to remove the isc-dhcp-common and isc-dhcp-client packages.

Then /etc/network/interfaces with the wpa-conf for /etc/wpa_supplicant/wpa_supplicant.conf and desired /etc/dhcpcd.conf settings finally worked.

There are probably other ways to fix the problem like fiddling with the networkd just not as easy.
