Christine from Huntington Beach, CA
Wi-Fi

Christine's son has a laptop that has completely lost its Wi-Fi connectivity, but it still works when its hardwired. Leo says that laptops have an Airplane Mode with a function key that will disable the wireless connection. It may be that he accidentally disabled it. They should look in the Wi-Fi settings to see if Airplane Mode is on.
