Double net and ip addresses allocation

Double net and ip addresses allocation

I am confused by who allocates isp addresses. Connection is: ONT--> isp router--> my router ("X")

Isp router does not allow DHCP switch off and is necessary to connect my phone to it.

 

1. If I let the isp router handle ip addressing, to avoid resetting all devices on my current router (X), can I give the isp router the same SSID as X? X has ethernet wired switches - will the same name cause issues?

 

2. If I turn off WiFi in the isp router, presumably X will provide the ip addresses (as it is now). I can ignore other ethernet ports in the isp router so only address given by it is the X ip address.

 

3. In 2 above, any other double net issues I need to consider?

Thanks a lot. Let me digest this (being a newbie!) and come back.
