so today i installed a long network cable to my new room. first a 25 meter one, then a extender thing (ethernet ports at both sides) then another 10 meter cable and everything is in cat 6 but I only got 130/40 mbps and I am paying for 250/100. i tested with my laptop and a 1 meter cable from the router and i got 230/80 and im fine with that. does the connection get so bad from 35 meter (kinda 35 yards) away?i think its a bit strange that it losses so much. what should i do?
