I need to run an ethernet cable to another room which is more that 100m away.
My internet guy just told me that CAT5 ethernet cable range is 100m. He stated that it does not make a difference if we connect switch in between like 50m cable, switch and another 50m. He said that the length accumulates.
I think he is wrong about that. However, if I am right that switch can actually extend ethernet cable.
Then for each switch we can begin another 100m of ethernet cable? If so we can technically do this forever? Beside using switch should I get some other specialized device to accomplish this instead?
