I have been having an issue since I upgraded to the 50mbps internet service. My downstream power level is dropping, the upstream power level is spiking and my Motorola SB6120 reboots. At the same time, I tend to get pixelation on my TV. I've researched this issue here and elsewhere and it seems to point to a cabling issue. I have replaced the coax within my house and the problem continues.
How do I convince the Comcast customer support chat bots that I need a truck roll/technician to inspect the cable and connections external to my house? I haven't found the magic words as they keep sending signals to my equipment which obviously will not fix the issue. Any ideas or suggestions?
