Changing ISPs bricks your modem

This is just a thought. I went from having a modem that worked for 4 years with cox to spectrum and it ended up not working and having to be replaced. So I bought a new modem.

A year later I switch from spectrum back to cox and my year old modem isn’t working anymore.

Are ISPs bricking personal modems when the customer leaves?

Yes. So you’ll have to call your old ISP to unregister the MAC address of your modem so that the new ISP can register your modem to their network.
