New CM1200 modem and new coax but only 400mbps down with Gigabit service
Following up on technician visit... A tech came out to troubleshoot issues with coax in the home and did discover that the coax needed a splitter as there was too much signal. My power levels are much better and correctable and uncorrectable errors are good. The tech however was not able to connect directly to my modem for direct testing. He could only test through my Wifi router so we couldn't determine if my slower speeds are due to modem or router. I am now wondering if the wrong config file was sent when I provisioned the new modem and that is why I can’t get up to my plan speeds (1200mbps). Has anyone had a similar experience where the Tech couldn't connect directly to the modem for testing?
The logs on the modem also show that Comcast is trying to push firmware version 3.1 when it should be 3.02.01.
