Setting up the T-Mobile High-Speed Internet Gateway

Recommended setup: use the mobile app

Using the Quick Start Guide and the T-Mobile Home Internet mobile app provides the easiest setup experience. The T-Mobile Home Internet mobile app can be downloaded from either Google Play or the App Store.

Use the following instructions for managed setup only if you are unable to use the mobile app.

Manual setup: identify an ideal location

You will start by identifying the ideal location for your gateway—that location will meet the following criteria:

•Near a window where the signal strength is strongest

•In an open space away from:

▪Walls or obstructions

▪Heavy-duty appliances or electronics such as microwave ovens and baby monitors

▪Metal fixtures, enclosures, cabinets, reinforced concrete, or pipes

•Near a power outlet

•On an upper floor of the home or at least 6 feet off the floor

The following procedure will help determine the best location for your gateway.

NOTE

Once you find a good signal, do not reposition the device. If the position changes, you may need to verify the signal strength again.

1.Without using the provided power adapter, power-on the gateway by pressing its On/Off button.

2.Walk the gateway around your house and identify the window where it gets the best signal, as represented by the greatest number of bars on the LCD.

NOTE

You might need to repeat this cycle several times before finding the ideal location.

An “X” on the LCD indicates the gateway is not connected to the cellular network. For more information about the LCD touch screen display, refer to the section Understanding the LCD.

3.Once you've identified the best location, you're ready to connect the gateway to grounded, sustained power.

Connecting the T-Mobile High-Speed Internet Gateway to sustained power

Place the gateway on a flat surface, such as a tabletop or similar; close to a window and near an electrical outlet.

Minimize the number of obstructions as much as possible.

Connect the gateway's power cable to its Power

port. Plug the other end of the power cable into a grounded electrical outlet.

Starting the T-Mobile High-Speed Internet Gateway

After the gateway is connected to a power source, start the device by pressing the On/Off button located on the backside of the unit.

The LCD screen on top of the gateway displays an animated T-Mobile logo that indicates the gateway is starting up.
