Aluminum wire 20 meters long, speed has no impact?. How many megabytes is the Internet speed?.
No influence, my home that cable lead all over 30 meters, still the same speed.
Relatively small impact. General copper wire, but 100. Aluminum has seventy or eighty handles
If you ask this question, you sure this line is home to use the Internet to pull the line, at best is 20Mb fiber Internet bar, the copper wire at a rate of 20 meters can not pull, will not have influence on the speed.
