We had a new Fios set up a week ago. Our connection is 100/100. Router we are using is Verizon Fios G-1100. Today, we were experiencing very loe speeds on 2.4 GHz. When I did a speed test on both, 2.4 GHz gave a speeds of 4Mbps/1Mbps, while on 5 GHz I am getting a full of 100Mbps/100Mbps. Why is this happening?
