We have 3 mac devices connected to wifi. Last night one device indicated no wifi and despite all the usual measure to fix, none worked. Other 2 devices were fine. Took it to Staples and they connected it to their wifi okay. Got home it worked. What on earth could have caused one Mac Airbook to do this, any thoughts? Do we need a new airport card if this happens again?

Next time it happens try running wireless diagnostics to see if that tells you anything. Holding the Option key when clicking on the wireless icon in the menu bar will show that menu item.
