My Router is a Nighthawk R6400V2 with Firnware V1.0.4.84 installed. The Xfinity Gateway was a Techicolor Model DPC3941T. Tested speed with My IPhone XR Model MT3T2LL/A modem firmware 2.03.07, wireless chipset appears to be called U1? Tested using my Samsung Smart TV KS8500 series 802.11ac WiFi chip. Tested with Amazon 4K Fire Stick. Hopefully this information is what you need if something else is necessary le me know and I will see what I can do. Thanks

So right now you're going CM500V-----R6400v2?
Before you were going DPC3941T-----r6400v2? or just the DPC3941T? this is a combo device so if you were using this before with the router connectd to it, try factory resetting the R6400v2 and reconnecting to the modem. many times settings are retained when switching between modems/services.
When you're speedtesting over FireTv's and samsung tv's, its not a reliable indicator because many things can influence those speeds. From the speedtest site those devices use, placement of router, metal backplate for tv mount, to wireless interference. Way to many things impact those tests to be reliable.
try to use both your phone and a hardwired pc for speedtesting. And even with the phone, make sure you're connecting ot the 5ghz radio as the 2.4ghz radio has much lower throughput.
Test in several locations with the phone and do a hardwired test on the router to see what your hardwired speeds are.

Thank you so much I did as you instructed and now everything is working, the WiFi signal is strong throughout the house, guess the R6400V2 kept the settings from when it was used with the Xfinity gateway/router.
