Repositioning for a better signal
After performing the Using the signal test button procedure to determine the quality 
of signal, you may want to reposition the FastMile 5G Gateway 3.1 for a better signal, 
do the following:
• power off the FastMile 5G Gateway 3.1
• disconnect the gateway from the electrical outlet
Note: Once you have a good 4G/LTE or 5G connection, it is recommended that you do not 
relocate or rotate your device. It is strongly recommends that you position your device near 
a window, where the best 4G/LTE or 5G signal is expected. 
However, the omni-directional antenna is less susceptible to Internet speed changes when 
rotating the device since it does not have a directional antenna. 
Rotating your device may still influence the Internet speeds due to Indoor signal reception 
conditions.
