I have been using Comcast/Xfinity since 1995. At present, I am paying for the boost package which advertised as up to 400 Mbps down and 12 Mbps up. My current download speed with my PC connected to the gateway with an ethernet cable is 63 Mbps. For over a year now I have been struggling with this slow download speed and intermittent drop connection. The techs have been out to my resident multiple times and have not been able to isolate the problem. The last time the technician was out, he replaced the cable from the street to my dwelling. He also replaced the cable from the wall to the modem.
I have replaced three modems. Two Arris SV2482AC and a NETGEAR Nighthawk Multi-Gig Speed Cable Modem for Xfinity Internet & Voice. Docsis 3.1 Technology (CM1150V) chasing a fix for this problem.
I now think the problem is upstream from the modem. I have seen similar issues here. I would like to know how they were resolved.

Thanks for the reply. I had a technician ( Ralph) on site at my house on Thursday, April 4th. He was able to troubleshoot the problem down to a faulty amplifier in the junction box outside of my house. I was very impressed by this young man's patient and depth of knowledge. I am now getting the download speed that I am paying for, and I no longer have spotty or intermittent internet.
Thanks a million.
