How is the ISP performing this remote update? Is it TR-069/CWMP or an open SSH port or something? Many routers will allow the user to disable TR-069 even while it's running. Often a hardware reset will also disable it and then the user can put the manufactures update on it and prevent the ISP from managing it in the future. If it's an open SSH port then we all have bigger problems.
- sean8102 8y agoAT&T's internet service requires you to use one of THEIR "gateways". Which is a combination modem and wireless router. When AT&T wants a new gateway they go to a company (mainly Arris now) and have them build a gateway that will only be for AT&T to deploy . AT&T completely controls the software/firmware on the device. There is no site you can go to and download a "manufacturer" firmware. Even if you could it wouldn't accept it because it wouldn't be signed by AT&T. And yes AT&T uses CWMP to remotely manage the gateway. That's how they can send firmware updates, customer service can retrieve signal stats, remotely reboot the gateway etc etc. And no they certainly do not put in a option on the gateway to disable CWMP or any of the remote management stuff they use. You can turn off the Wi-Fi on AT&T's gateway and run your own router behind the AT&T hardware. But since your router is behind the gateway everything still goes through it and AT&T still can do all the CWMP stuff to their gateway.
