Do not get stumped, just read the UC300ETH users manual: http://cncdrive.com/MC/UC300ETH%20da...ETH_manual.pdf
If you will read it then you will see that your IP V4 settings are wrong, that is why the UCx00 utility tool telling you that it is wrong, it should be 10.10.10.10 and the subnet mask 255.255.255.0 and not 10.10.10.11 as you wrote you set it up.
