How to have wifi disabled if LAN interface receives IP address

Help and Support Raspberry Pi

As per the title, I’m running into an issue where my Pi 3 boots up and the on board wifi connects before the LAN adapter receives an IP via DHCP.

So then the Pi boots up with two interfaces in the same subnet which is less than optimal. The result is mDNS/avahi resolving doesn’t work for the pi amongst other things…

I’m just wondering what others may have done where they want their wifi to be configured, but not used if the on board LAN gets an address (or is simply “up” ?

Thanks,

Matt

I just enable the interface I want to have. And - usually I do have specific Ip-Addresses for my devices.
