Perhaps you meant 300 feet, not meters? (well, 328 to be precise)
Ethernet over twisted-pair is only spec'd for 100 meters. It's not just
a matter of signal integrity (though higher quality cable certianly
helps) but beyond 100 meters the propogation delay exceeds the timing
allowances in the low-level link layer protocol.
