About Ender-3 V3 Plus fixed IP address

My home router server does not have a DHCP server.
The WIFI router is an access point and all devices have fixed IP addresses. How do I connect the Ender-3 V3 Plus to the WIFI? Can I set a fixed IP address for the Ender-3 V3 Plus?

Doesn’t the WIFI router have a DHCP server? Neither my Sonic Pad or Nebula Pad can have a fixed IP address, they get what they are given. Can you reserve an address on the WIFI?

Get a raspberry Pi, install Octoprint, give raspberry pi fixed address (or alternatively, never turn it off). Print via web interface by opening a web page to the Octopi server running on the fixed-IP address Raspberry PI…

Thank you everyone for the information.
I understand that the 3D printer does not have a function to set a fixed IP address.

According to the WIFI router user manual, the DHCP server cannot be used in access point mode.

I have several Raspberry Pis, but I don’t think it’s a good idea to use them for DHCP.

My main server is a slightly old version of FreeBSD, so I think the best solution is to get the source code for the DHCP server and compile and start it.

This is the first time I’ve purchased network equipment that doesn’t have a fixed IP address.

Thank you very much.
