I just got off the phone with a Comcast tech, and wanted to double-check

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.
