randald10 Welcome to the community!
We have just initiated the modem exchange. You will receive a new modem within the next days. Since your modem is already set to IPv4, this setting will be applied to the new modem. If not, please contact me.
In addition, you will have a faster speed, because the modem has only 250mbit throughput, but your subscription has a higher speed.
Greetings
Daniele
