I would like to know which version of Ubuntu are you running on your laptop? Specifically, I want to know what's behaving as your dhcp client, is it dhclient or systemd-networkd?
Requesting IP addresses from two interfaces on the same machine to one DHCP server is sometimes causing trouble because in systemd-networkd it sends Client-Identifier to the server (which is about your D-Bus machine-id), and some DHCP server (as far as I know at least some versions of ISC DHCP Server) will take Client-Identifier as precedence over the interface mac address, thus generating IP address allocation problem.
