T-Mobile Home Internet Frequently Stops Working
My T-Mobile home internet has problems every single day - either agonizingly slow or not working at all. I have called almost everyday for 3 weeks now but woke up this morning with 9 mps. ...
The download speed is so poor. Try to record the cellular metrics when the test is good and poor. http://192.168.12.1/TMI/v1/gateway?get=all
The ping latency is high when the signal is poor and the jitter reflects erratic behavior. I would suggest to favorite the Syosset, NY server. Some others may be closer but that server seems to have more favorable response metrics. On the last test the phone only reported 2 bars on the cellular signaling. To see more about the cellular signal strength the phone records you can put your phone into FieldTestMode and see the RSRP cellular signal strength. To do so you enter *3001#12345#* then enter/send. The dashboard will report the RAT info. Select the menus bars at the top right to see 5G NR connection info. Scroll down for the LTE info and the serving cell info. The serving cell reflects the band the service is currently on. The PCI value is the physical cell I'd and the RSRP is the signal receive power. The PLMN and cell ID help to locate the serving tower on CellMapper.net if you want to determine where the tower is and how far away it is. This information helps understand how the signal is and also can be helpful when trying to improve the signal.
The poor download speeds make me suspicious that the gateway is not holding a 5G signal and reverting to 4G LTE on the primary signal. It would be good to know if the gateway is holding both the primary and secondary signals or not. The LED screen will not tell you about that.
