My wifi on my laptop is not working. Steps I have taken - Replaced Airport Card - Reinstalled OS - System resets Looks like there may have been some water damage, but its odd that the Bluetooth still works on the machine. Anyhow, I am using a usb wifi card and I can get to the internet fine, but I am not able sign into Itunes with my icloud device. It gives me a message that this computer can not be verified. I have tried to use a thunderbolt to Ethernet and get the same message. Is there some type of restriction that you must use on-board wifi to get authorized for Icloud?
