Constant packet loss - support refuses to acknowledge
I have been suffering from heavy packet loss during work hours (around 9am - 6pm). All my colleagues comment that I freeze during video conference meetings. I have spoken to online tech support multiple times and they seem to refuse to acknowledge this issue exists. At the recommendation of online support I have replaced the switches in my home, the cabling, my router and my cable modem (from a Motorola MB8600 which apparently was fine to a Netgear CM1200). I have been continously checking the SNR and power levels on my cable modem and using pingplotter to see where the packet loss happens. I'm convinced it's outside my home, but I can not 1) get a technician to come or 2) get comcast to even acknowledge that there is a problem. Please help. See below my most recent communication with tech support.
