Disable secondary (5G) connection

I made, and attached, a PDF that I made from investigating the router. I found if I rotate the router so the 5G-3 and 5G-4 antennas are facing the direction of the tower I can improve the signal by ~4-5 dBm and improve the SNR. If the signal to noise is improved that is important for performance. I found a slight rotation of even 3-5 degrees can have an impact on the signal. It is worth the time to try to improve the 5G signal. If you want to get serious go to waveform.com and check out the external antennas. They can probably set you up with the 4x4 log periodic and that would have a positive impact. Not cheap but smart.

If you know where the tower is great. If not then get the PCI value for the cell and use cellmapper.net to locate the 5G tower. If you call T-Mobile they should be able to provide you with coordinates of the tower so you can improve the cellular link. 

My router runs 1.2103.00.0338 code and took that a week or so ago. I recall reading that the router will take an update if it is rebooted. I asked about getting the code to update it but was told that was not how it was done. I may be wrong but I believe the information I read suggested T-Mobile will push the update and the router has to be rebooted to take it. I have run the Nokia router on n71 on the secondary signal since January. I have a 5.3 mile distance to the tower and I get RSRP -80 dBm with a SNR 22 dB and RSRQ -11 dB. I have seen the 5G improve a few dBm (-75 dBm) but that is when the air is clear and conditions are best. I took focus on the 5G signal improvement and let the 4G LTE primary signal be whatever it is. The 4G LTE is never as good as the n71 5G signal and does not have the performance I can get out of the 5G signal. That is my experience at any rate.
