Internet Mesh Wi-Fi Extender v1 white front and back

  • You can set up your mesh Wi-Fi extender with an ethernet cable.

    1. Plug in the power adapter and connect it to the mesh Wi-Fi extender. Your mesh Wi-Fi extender should be close to the gateway.
    2. After the mesh Wi-Fi extender is connected to a power source, you should see the LED color change from solid white to blinking white. This takes a few minutes.
    3. Connect the mesh Wi-Fi extender to your gateway using the provided ethernet cable.
    4. Wait for the LED on your mesh Wi-Fi extender to change from flashing green to solid green. This takes a few minutes.
    5. Your pairing is now complete.
    6. You can now remove the ethernet cable from the gateway and the mesh Wi-Fi extender.
    7. Follow directions for finding an ideal location.

    1. Place the mesh Wi-Fi extender where you have the least Wi-Fi coverage or where you use the Internet the most, in an area that’s away from the gateway and near a power outlet.
    2. Make sure it is in an open space and:
      • Away from devices that may cause interference.
      • Not behind TVs and monitors.
      • Not behind walls or obstructions.
      • Not behind heavy-duty appliances or electronics such as microwave ovens and baby monitors.
      • Not behind metal fixtures, enclosures, cabinets, reinforced concrete, or pipes.
    3. Once the mesh Wi-Fi extender is connected to the power source at this location, the LED should change from solid white to blinking green and finally solid green. This will take a few minutes.
    4. If your mesh Wi-Fi extender shows a yellow or red light after you plug in, unplug it, and move it closer to the gateway.

    1. Connect your wireless devices to your network using the Wi-Fi SSID (Wi-Fi name) and Wi-Fi Key (Wi-Fi password) of your gateway. Refer to the Gateway & Network Set Up page for more details.
    2. Use the T-Life app to check signal strength.

    • Avoid prolonged exposure to direct sunlight, particularly in warm climates.

    • If it feels hot, unplug it immediately and let the device cool before plugging it in again.

Troubleshooting

    • Verify your gateway and mesh Wi-Fi extender are both powered on.
    • Try placing the gateway and mesh Wi-Fi extender in a different location.
    • Try factory reset.

    • The LED displays solid red to indicate there is no network signal, which could mean your Wi-Fi network is down due to several reasons.
    • Be sure your gateway is turned on and working properly or try placing the mesh Wi-Fi extender closer to the gateway.
    • If the connection does not improve, contact T-Mobile Internet Customer Service.

    • If the mesh Wi-Fi extender does not start, verify the provided power adapter is connected to a working outlet and plugged into the power USB-C port on the mesh Wi-Fi extender.
    • If the mesh Wi-Fi extender is connected to an outlet and power still does not start, contact T-Mobile Internet Customer Service.

    • If you feel your overall internet experience is poor, try repositioning the mesh Wi-Fi extender.
    • You can also use the T-Life app to help diagnose the issue.
