Getting to Know Your T-Mobile 5G Gateway

You will find the following items in the box:

Gateway
Power adapter
Quick Start Guide
T-Mobile Terms and Conditions
Safety and Regulatory Notice

The gateway offers 4G/LTE or 5G/NR WAN mobile network connectivity by way of four wide bands of OMNI antennas that support all LTE/5G bands. It functions as the connection point between the WAN outside your home and the LAN inside your home.

Physical Interfaces

The gateway’s physical interfaces include those shown in the diagram.

Setting up the T-Mobile 5G Gateway

Recommended Setup: Use the Mobile App

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

NOTE
The first time you access your gateway, the “How to navigate this interface” displays on the LCD panel. Select “OK” to continue the start-up.

Download and install the Mobile app using your smartphone, then the Mobile app establishes communication and connects to the gateway.

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

Connecting Power to the T-Mobile 5G Gateway

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 USB Type-C power cable to its Power port, then plug the other end of the power cable into a grounded electrical outlet
The USB Type-C power cable must be capable of supporting 100–240V (volts) AC adapter, 50–60Hz frequency, and 3A of current at DC 15V

Starting the T-Mobile 5G Gateway
After the gateway is connected to a power source, the LCD screen displays an animated T-Mobile logo that indicates the gateway is starting up.

Four small dots displayed on the LCD panel indicates available screens. Take a moment to browse these screens to see what information is available. For more information about the LCD screen display, refer to the section “Understanding the LCD” on page 19.

The start-up sequence is complete when the LCD shows:

Troubleshooting

No Signal
This LCD alert indicates there is no network signal, which could mean local cellular equipment is down for any number of reasons, or the gateway may need to be re-positioned.
If the connection does not improve in a reasonable amount of time, you can contact T- Mobile customer service or refer to the section “Manual Setup: Identify An Ideal Location”.

Prevent Overheating
Make sure that obstacles never obstruct airflow vents on the top or bottom of the gateway’s enclosure. Allow at least 100mm/4in clearance on all sides of the enclosure. Ensure the gateway is at least 3 feet from baseboard heaters.
If the gateway feels hot to touch, unplug it immediately and let the device cool before plugging it in again.

T-Mobile 5G Gateway Does Not Start
If the gateway does not start up, verify the provided power cord is connected to an outlet. If the gateway is connected to an outlet and power still does not start, contact T-Mobile technical support.

Poor Internet Experience
If you feel your overall internet experience is poor, try repositioning the gateway; refer to the section “Manual Setup: Identify An Ideal Location”.

Forget Your Admin Password?
If you configure a custom admin password and forget it, use the password reset function found within the T-Mobile Internet mobile app to reset the password to factory default.
