I would second this. Many newer laptops have soft-buttons for wifi/sound/etc..
that traditionally would just save states between boots. I have 2 SSDs in my
laptop, one with the original W10, the other with Arch. I've noticed the
soft-buttons are configured differently depending on whether I boot windows
(once a month for updates) or a normal boot of Arch. (behaves the same with
openSUSE as well) I wouldn't be surprised if the wifi soft-button defaults to
off. I have a light within 4 independent buttons that show the state of wifi,
sound, etc... Double-check yours when you boot the Arch installer.
With the arch installer, if the wifi chip is enable, it should be picked up
and enabled automatically. As others have said, save the output of
(write it to a usb drive or something) and post the output just to confirm
that there isn't some left-field chipset used (doubt it, but that would confirm)
If you have a RJ45 connection for a wired connection, that's always an option.
