None of it works with Wifi though. iPXE has wifi support for some devices but you obviously can’t start it over the Internet. You need to flash a ROM you don’t need or use a USB drive to load it. Then you can boot Linux from the Internet. (That also works if you don’t have a UEFI Shell in BIOS). https://netboot.xyz can also boot other OSes than Arch.
Of course it can. What did you expect?
