Can't connect to network on FW13 Ryzen DIY with Windows 11 install

I have built a DIY FW13 Ryzen 7040 and I’ve followed the instructions regarding the Rufus, Windows download etc. I’m setting up windows and I’m now at the screen that says, “Lets connect you to a network” but the next button is greyed out. I followed the instruction on this page line by line.

How do I get past this screen? Also, from here there are no instructions how to install the driver package and update BIOS.

Thank you.
