Built In Wifi Not Working Raspberry Pi 5 and 2.9.4

I installed Linuxcnc on an 8GB Pi5 using this file since I want to use a MESA board, it looked like the right choice.

www.linuxcnc.org/iso/rpi-5-debian-bookwo...25-01-27-0140.img.xz

Everything booted up well(but there was no initial setup wizard like I have seen some people mention), and the install looks good, but I don't see wifi anywhere or network options of any kind. I tried a USB wifi dongle, and that didn't change anything and unfortunately, ethernet is not an option for me. Does anyone have any tips for getting wifi working? Should I have used the other .iso? Thanks!

I don't know where you saw the info about the setup wizard, but this is absolutely wrong.
As the image is essentially Debian Bookworm you can use the below link to get an idea. Also there is a large sticky thread related to the RPi images, in the Installing Linuxcnc heading.
What other image are you referring to ?

wiki.debian.org/NetworkConfiguration

to set up, first connect the Ethernet to your router and let it get an IP address via DHCP
To set up wifi, follow the instructions on the downloads page.
Now you have it working if you need to set up for a Mesa card, follow the instructions
