I recently upgraded to the gigabit plan for home internet. Wired I get around 550 down but the wifi is much slower. I understand wifi will not be as fast but I'm testing at under 70 down right next to the router. The up speed in these same tests was above 90. In other parts of the house I am testing below 40 down. Is this normal for fios gigabit wifi? Are there ways to at least get my wifi above 100 down.
