Good points, I totally didn't even think of that. I get about 25 Mbps from my computer with a wired connection. I did a speed test with the phone right next to the router and was getting speeds very close to that. Down the other end of the house I get about 10. It seems to average around 12-15 with the 4G. So I suppose I could upgrade the router but those speeds seem plenty fast for me. For some reason I was thinking that the WI FI used more battery but since it doesn't, I will just leave it alone. I was more concerned with that than the speeds since they are all fast. I did notice some smart actions required it on anyways. By the way it is using WPA.
