I do not want to rent a modem from comcast, so I need help finding the best modem for a 20mbps plan in a 2900 sq ft house while also having a good signal in a workshop approx. 300 ft. away from the house.
I currently only have experience with all in one modem/router devices. I was leaning towards the 6121, but I can honestly tell you I have no idea what dant_45 meant by a netgear router. Upon searching newegg I found items ranging from $50 to $800.
