In fact, *all* cards should handle 50 meters ~= 162 feet, or they don't meet the spec. But before you beat up WD, which type of transceiver cables are you using (mfg & model) and what kind of transceiver (ditto) are you using? Those can also be the culprits. The maximum unrepeatered 10BASE5 segment (again, the yellow stuff) is 500m (1640.42 ft), and the maximum AUI is 50m (164.04 ft). That's the spec. It is certainly possible the tranceivers are not up to spec, and are causing the problems; although the original poster did not mention whose tranceiver he was using, he did state that WD "knew of the problem", and thus it seems likely to be on their end. As an aside, our stuff is all tested at the spec (these BIG spools lurk in the darkened corners of the lab waiting for you to trip over them...), and passes without problems.
