I should also mention, so far any bandwidth speed test that I conduct shows max that I am getting is 342 Mbps. Even with the prior 400 Mbps, which Xfinity upgrade us “for free,” our service maxed at 300 Mbps. My cable modem is DOCSIS 3.0 and should be capable of up to 800 Mbps, the ethernet ports of modem the modem and the other end of my Internet router are 1 GigE. Iperf3 tests between 2 hosts of of my router with wired connections can sustain 940 Mbps, so all my equipment should handle 500 Mbps. Now that I am paying more I will also complain about the fact that I am not getting the expected speed. I am also expecting Xfinity to say I need their cable modem versus the one that I own and am using.
