100 metres is the maximum unrepeated length of CAT5 UTP cable (assuming thats what youre using). do you absolutely need that length or can you go shorter?
yeh i probs need 100m will hav to measure the length, cable will b going from 1 house though the roof then makin its way to the granny flat in the backyard which is some distance..
will it lose its speed? im guessing ther will be some loss unless i get a good quality 1
wouldnt be easier to go wireless? 100 metres is quite a distance, so you could always buy that length, and trim any extra length off you might not need just to avoid any issues
