It is strange to me that your machine wifi connection drops when it renews
a lease. Personally, I've never experienced such behavior. Could this be a
bug in network manager ?

The dynamic range has been intentionally configured to have a short lived
lease. This is because machines that enlist/commission obtain IP address
from these range, and holding long leases causes IP exhaustion. Machines in
the dynamic lease are not ensure to keep their leases forever. This is why
we allow the creation of devices with a 'Static' IP address.
Has anyone else noticed this behavior?

You need to register your machine with an static IP assignment, and MAAS
will create a hostmap for your machine.
'Nodes' > 'Device' > 'Add device' > 'IP Assignment -> Static IP'
If you want to do further configuration of your DHCP server, then you need
to use DHCP snippets. You can create custom snippets per device.
'Settings' > 'DHCP Snippets'
Hope this helps.
