Sorry, I was a bit busy. I make a clean install of my OpenWRT-Build and here is all logs I have assembled as all honorable members of this community requested:
first I typed:
/etc/init.d/dnsmasq status and it was not running so problem still exists
then I collect all other info
logread | grep dnsmasq
