5G home internet keeps dropping

With the trees an external MIMO panel antenna might help out quite a bit. If you can get the n71 stronger sure that would make it more satisfying. Your router records B66 and n71 so the cell info in the second image with site 3154402 reports NB B71 but does not provide the PCI for 100% verification. I am not convinced that is quite the same. The n71 5G NR is an extension of the 600 MHz bands to enhance the 4G LTE by swapping out part of the banding to leverage the 5G. It depends upon the operation. If they are swapping 10 MHz of 4G for 30 MHz of 5G on n71 then that is where you would get a significant boost. To be 100% you really have to know the PCI of each band and identify the tower that has that PCI, physical cell ID. With the web version on my client at home using cellmapper.net I was able to get the low down on both the 4G and the 5G signals. The phone may not report or connect to the same towers as the router. It can be somewhat helpful but the PCI is important to have. Once you are 100% on the tower delivery to the router then you can really dial it in. An external antenna might help considerably but would have to be located properly to really make it rock and roll.
