Hi, I don't know if this is gonna help, but when I first installed Arch I had the same problem. What solved it was bringing my wireless interface up manually after activating the wifi switch. So check out your `ifconfig` output. If you don't see your wireless interface bring it up. `ifconfig wlan0 up`, or whatever your wireless interface name is.
