My Internet is 200 Mbps Down 5 Mbps Up. I have been having bad connection problems lately and I think it is my cable modem and router. It is a Docsis 3.0 modem and Comcast used newer Docsis 3.1 modems. I ordered a new one from Comcast to see if this helps my connection problems. If it does you are right I may not need a new PC after all. So I should just probably wait and see.
