What is involved when doing an upgrade from cat5e to cat7? or is it even worth it? Do I need to change my cables or just the jacks. I am currently paying for a 1.5 Gb internet speed and a device connected to a cat5e runs at around 550 - 650 Mb. My PC connected to a cat6 runs 950Mb max. Will changing to cat 7 make it close to what I am paying for or will my cable bottleneck it? Not sure if it is significant but the house is 20 years old and the cabling was done then, based on the original jacks it had, mainly for telephones.
Make sure both the routee and your PC have a port that supports more than 1gbps.
My router only has one 2.5gbps port, and not all MoBos (or NICs) support 2.5gbps.
