As the Comcast gateway will not let the user change the DNS settings in it, I plugged a router into the gateway and input Cloudflare's addresses into it. For added measure, I also set the WiFi connection from the Android to the router to use a static IP address and also manually input the same DNS' for the connection. In using the router, I am losing IPv6. The router supports it, but I was not able to establish a successful IPv6 connection with it.

Prior to this - connecting directly through the Comcast gateway but also using Comcast's DNS' through the router, the phone displayed download speeds of 50Mbps and upload speeds of 11Mbps. Using 1.1.1.1 via WiFi, I am now seeing download speeds approaching 56Mbps and upload speeds approaching 13Mbps, via the same app and web site. This is all via 2.4GHz.

No. You changed the Comcast hardware out for some other
hardware. A 10% change is well within normal parameters.
