5 years ago I was told that I cannot go faster than 150mbps in my house due to COAX. My house has ethernet and coaxial cables in nearly every room BUT all of the cables go to a box is located in the middle of a large finished basement and it is only COAX from that box to the ONT. Is it still true today that without using an ethernet cable, I will not be able to get gigabit speeds through coaxial cable? Fishing ethernet cable through ceiling joists and walls from the ONT to the network box is not an option.
