Unit stopped getting DHCP after a reboot. It hadn’t been rebooted in quite some time. Its a pi3. I confirmed with my router it wasn’t seeking dhcp. I confirmed the settings are still set to get dhcp on the pi. I checked the /boot/piaware-config.txt and both wifi and wired were being used (I dont use wifi).
So I took the chip and put it into a working raspberry pi to be sure it wasn’t a blown ethernet port and it wouldn’t get DHCP there either. So I tried with a different router to be sure it wasn’t my network. It wouldn’t get DHCP there either.
From what I could see one network file sets it to manual initially but then calls on some /var/lib dhcp files. In those files are the last lease I had and correct ip addresses. But it will not work.
