Resolve T-Mobile Gateway Loses Signal

If your T-Mobile gateway loses signal or has no signal when the new external antenna is attached, Poor antenna placement, antenna cable issues, gateway issues, and network congestion can all contribute to signal loss.

There are several reasons why your T-Mobile gateway may lose signal or have no signal when the antenna is attached. Some of the most common reasons include:

1. Poor Antenna Placement

The T-Mobile New Internet External 5G Antenna needs to be placed in a location with a clear line of sight to the nearest T-Mobile 5G tower. If the antenna is obstructed by trees, buildings, or other objects, it may not be able to receive a strong signal. Make sure that the antenna is installed in a location with a clear line of sight to the nearest T-Mobile 5G tower.

  1. Check the location of the antenna and make sure that it is installed in a location with a clear line of sight to the nearest T-Mobile 5G tower.
  2. If the antenna is obstructed by trees, buildings, or other objects, try moving it to a different location.
  3. Use a signal strength meter to check the signal strength of the antenna in different locations.

2. Antenna Cable Issues

The cable that connects the T-Mobile New Internet External 5G Antenna to the T-Mobile 5G Gateway (G4AR & G4SE) may be damaged or improperly connected. Make sure that the cable is securely attached to both the antenna and the gateway, and that there are no kinks or bends in the cable.

  1. Check the antenna cable for any damage.
  2. Make sure that the cable is securely attached to both the antenna and the gateway.
  3. Try using a different cable to see if the issue is with the original cable.
  4. The T-Mobile 5G Antenna is only compatible with the T-Mobile 5G Gateway (G4AR or G4SE). In case you are not connecting them then there will be loss of signal.
