Use iwctl to setup wireless connection. Otherwise, if you are on ethernet, skip this step:
iwctl station list # 1. Find your wireless station name
iwctl station wlan0 scan # 2. Scan for nearby networks
iwctl station wlan0 get-networks # 3. List discovered networks
iwctl station wlan0 connect <ssid> # 4. Connect (replace <ssid> with your network name)
ping -c 3 archlinux.org # 5. Verify connectivity
