You can do adb shell getprop | grep -i dhcp to see the dhcp related
properties
One of those should be dhcp.<interface>.reason which indicates why things
failed
If that is not giving enough information - you have to go turn on manual
logging in dhcp daemon to see what is going on. We do not have an easy way
to do this on ICS.
