I have cable internet via spectrum, I also have the netgear xr1000 which I love because of the dumos features. I want to switch my service to fiber optic because it's better an faster. I don't know what speed I should get, I was thinking 3g but I would need to switch to a 10g router, I don't wanna give up my xr1000. Is 3g necessary I live in a small house and I'm the only one in here gaming or is the one or two GB service adequate?
