The Mobile Hotspot application can share the phone’s 4G data connection with any Wi-Fi capable devices.
There are security risks associated with creating a Wi-Fi network open to the public. It is highly recommended that you take steps to protect your Wi-Fi network from unauthorized access. To add encryption to your Wi-Fi Hotspot:
Touch the Mobile Hotspot checkbox to enable this feature.
Read the disclaimers and Help information, then touch OK.
Your portable Wi-Fi hotspot is now created.
You can use this menu to enable and disable the connection. Once the connection is active, go to the device you want to connect and configure its wireless connection to the Network SSID for your Android device and input the password (if you are using WPA2 PSK). You will now have wireless access on your device.
WEP is highly vulnerable to hacking. WPA2 is recommended by the IEEE.
The following Status Bar icon indicates your Wi-Fi Hotspot status.
