The MT Routerboard 4-port NIC with Via Rhine chip is awsome to reach 450ft over ethernet. We had been told in the past that it was needed to have the via-rhine on both sides of wire, but in actuallity we learned the opposite, and have been very effective with having the long-range ethernet card just on one side of wire.
Otherwise, consider... If there is noise on the Ethernet? Use thick shielded Superior Essex DB cable, and you can push the limits of Ethernet. Otherwise consider calculating loss, with Demarctech's cable voltage loss calculator, and increasing voltag slightly to compensate, in case it is voltage and not just ethernet. Lastly look for sources of noise injection, and block it. .
