Tmobile home internet SINR and RSRP issues

If the signal received is poor where it is you need to relocate the gateway. I suggest closer to a window and commonly a little higher up may help. Use the T-Mobile home internet application on your phone to do the location to determine the direction where the tower signal comes from. You can start there and see if the signal reception can be improved. It really is necessary to optimize the location of the gateway to get a better cellular connection. The cellular signals can reflect off surfaces so placement may require a little experimentation. Placing the gateway in the core of the home where appliances might interfere with the signal can be a significant problem. You can turn the gateway a bit clockwise or counter clockwise as you experiment. With some of the gateways just the exposure of the proper antennas toward the signal source can make a difference. I have the Nokia and I have to turn mine 180 degrees facing the front toward the outside to improve the reception. Even the components in the gateway can impact the signal reception to the antennas on some of the gateways. There is no rule of thumb. It always takes experimentation to find the best location. Every location is different and some homes have better signal exposure than others. If you can get the LED display to at least show three bars that is a good start. If it only reports two bars I would continue to experiment. Use the cellular metrics to fine tune it. Improving RSRQ and SINR will help it perform better. Sure stronger RSRP is good but improving signal quality and less signal noise helps as a cleaner signal does perform better. With the cellular modem just setting it in a convenient spot most often does not provide the best results. I had to really work at improving the reception to mine. 

Just in case you don’t have a table to translate the cellular metrics.
