I own my own FIOS Quantum Gateway Router model G1100 (purchased from Amazon).
But Verizon can apparently access it, thru its ACS (auto-configuration servers) based on the TR-069 protocol (aka CWMP protocol).
Is there a way to disable such access from within the Quantum Gateway router? I could not find anyway to do it after logging into my router. The router manual has no answer.
No one at Verizon can answer this question either.
