I have recently increased my network speed from 100mb to 1gb at my home. The router is located in the opposite side of the house from where I usually am. The thing is, in my computer I am getting constantly the old 100mb speeds whereas if I connect directly to the router I get the 1gb. Can the internal wiring of the house be the problem or even the ethernet wall jack (using T568A) and is there a solution to avoid rewiring everything?
