IIIRC the problem is in the busybox DHCP which doesn't retry on 
failure by default, 

fortunately this is just a config option for busybox, so if you
do a make busybox-menuconfig you can change that behaviour


run "udhcpc --help" on the target to see what options are 
available

set IFUPDOWN_UDHCPC_CMD_OPTIONS to whatever fits you ned
