Is this your network? If NOT, request assistance from the Web Master/Network Administer.

If so...

• Using a Password: For a password-protected network... Go To: Settings > Cellular > Disable Cellular > Settings > Wi-Fi > Enable Wi-Fi > Select the SSID > Enter the Password

• Verify the SSID Name (Name of Network)... Go To: Wi-Fi > Other > Enter your SSID > enter your password. If you are using enterprise card connection, then you must log in using a User Name and Password.

• Reset Your Modem/Router, by unplugging it, waiting 20 seconds, and then plugging it back in. Let it reboot itself, and see if other devices connect.

• Disable Cellular Data, as cellular data will overtake Wi-Fi every-time.

• Use in Open Spaces as keeping devices out of such spaces and not using them behind closed doors will avoid lost signals

• Use a Range Extender to amplify the signal.
