Has Your Wireless Network Configuration Changed?

Wi-Fi networks with encryption options like WPA or WEP turned on require computers to use matching security keys when connecting. If someone changes the encryption keys or passphrase on the access point, devices that worked before will suddenly be unable to establish sessions and Internet connections. Likewise (though less likely), if the access point settings are changed to require using a specific Wi-Fi channel number, some computers may be unable to discover it.

Action - Confirm the Wi-Fi channel number and encryption keys on your router have not recently changed (check with the network administrator if necessary). When using a hotspot, follow the provider's instructors for signing on carefully.
