So is there a hot new modem? I read this article that Xfinity is giving us all a speed bump. (https://www.engadget.com/2018/03/06/comcast-xfinity-northeast-internet-speed-increase/) At present I am already showing about 300mbps on the xfinity speed test through my DPC3941T Docksys 3.0 modem. So in order to get speeds faster than 300 do I need a newer better modem?? What is the new hot xfinity modem?
