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.
