Hi, I have comcast for a provider and I am suppose to be getting 20 mbps but I am only getting less than 2 mbps. I called comcast and they looked at our modem and they said everything seems to be going okay. I bought a Netgear Dualband router that can sends 300 mbps. Comcast told me that the router and the modem are interfering with each other. I have tried alot of things but nothing seems to work. What should i do to make my internet work faster?
