Hi Jon,
Your reply led me to check my machines. They were ok.Only DHCP clients.
I then checked the router's client list. It turned out that the guest network assigns the 192.168.101 addresses. Not documented! So I changed the hostname.urtwn0 from the guest network to the "real" network. Now everything works.
Thanks for your insight!

Hi Niels,
Sounds like you have two DHCP servers on the segment. The clients are
taking the offer from the server they have a pre-existing lease with.
When you move the USB adapter to another host, there is no preference
because it has no existing leases for that interface. It it takes the
first offer it gets.
I hope that helps.
