How to update mac address without calling ISP?

Question

Computer networks

Every time I reconnect the network cable to a new device, I need to call the provider to get the Internet working for me. I understand they update the mac address.
Without this, when the cable is connected, only the provider's website is loaded.
Tell me, can I somehow do it myself without calling the provider, and how?

Answer 1

You can, most routers have a MAC clone mode. You just drive the old MAC into the new router and it pretends to be your old device

Answer 2

Write down the MAC address and change it on devices.

Answer 3

Call the provider once and say - Stop doing shit and remove the binding to poppy addresses or untie only my connection.
Works!

Answer 4

Buy a normal router and go to the Internet through it.
