I just got off the phone with a Comcast tech, and wanted to double-check my sanity.
Somehow in the last 6 months I've managed to reach the exact same rep twice when dealing with an outage or a degraded service event.
I asked him to remotely reboot the modem because there was high packet loss.
Both times I've talked with him, he noted the high packet loss, started to reboot the modem, and then asked me point-blank if we had any PoE switches on our network.
When I said "yes", he said I needed to disable PoE because it messes with the Comcast modems and he can see "buildups" in his graphs that show power is "leaking" to the Comcast modem every 24 hours.
