First install help!

I am starting my first install of Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave 10.14.6 on an external drive but have been told that you need to connect with ethernet to install. Is there any way around this as I do not have access to an ethernet cable long enough to reach my pc.

I am using a wifi adapter usb on an amd system if this helps.
