Not to be “that guy” but the installation manual on the ArchWiki does say to install wireless drivers/networking software before you reboot out of the installation medium.
Yes, most laptops usually have a page on Arch Wiki for specific quirks, however most drivers are in the kernel and do not need additional installation (Intel, Realtek and the Qualcomm one maybe Athenian) are all in the kernel, you likely just forgot software to initiate connectivity with Wi-Fi like NetworkManager.
