Problem with Wi-Fi connection
Problem with Wi-Fi connection
Check the network setup on your Arch Linux system. Once configured properly, you should be able to obtain an IP address from your router by activating the dhcpcd service using sudo. Note that this process is unrelated to Wi-Fi—your virtual machine interprets the connection as a wired link.
It seems the package is no longer part of the standard base distribution. You'll have to either download and install it yourself, which requires chrooting into your system without a connection, or configure an IP manually via the provided wiki link.
Dhcpcd is no longer part of the Arch Base. For graphical setups you must install and activate NetworkManager. If you're not using one, add dhcpcd manually. You can choose either option for convenience; I recommend one based on your needs. Most modern GUIs rely on NetworkManager. To get started, boot the Arch installation media and mount your system to create a chroot environment. Otherwise, assign a fixed IP address.
Didn't you forget to add network packages when installing? It looks like you should boot from the install ISO, enter arch-chroot, run pacman -S dhcpcd NetworkManager, restart the install, and then enable it with systemctl.
