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.
