I think it's a cable lenght problem.
When installing cables at my home i have some cables over 30 Meter.
I had to correct the connectors. Twisted Pair is not twisted enough for
lenght over 20 Meters so you have to turn some cables.

yes a switch can help a bit but only for length about 20 meter each cable.
for 50 meter you need two switches or two 25 meters cable.
