USB network cards and DHCP

i have been trying use a USB network card for my satellite connection
but if i turn off the sat modem and turn it back on the USB card does
not get a IP address. If i mark the interface down and then back up it
does get an ip address or if i reboot it does get an ip address.
i regularly turn off the modem to save bandwidth (its on a timer).
i tried swapping the USB card with the permanent one as to which one
goes to the satellite modem but the system exhibits the same behavior as
long as there is a USB network card plugged in.
the only way i can reliably get an IP as to have both network cards
permanent cards and not USB.
right now i am using a mini-pci-e network card and the internal built in
realtek one and everything works fine
but leaves no room for my access point card.
i have tried all sorts of cards on different platforms IE 10.3, 11.0,
12.0 on both rasberry pi, rasberry pi2, i386 and x64 and the all exhibit
the same behavior-- if that USB card is plugged in then i cannot get an
ip after losing the connection and regaining it.
the lease file shows the IP as 0.0.0.0
i think it has to do with the order that the network is initialized, i
think the network is attempted to try and initialize before the USB card
comes back alive.
maybe someone else has seen this before?
just grasping at straws here.
