Slow 4G connection only, but only sometimes -- SOLVED

007BondM16 have you identified the tower connections 100% i.e. you know the PCI the router reports for both the 4G and 5G NR channels? Uso http://www.cellmapper.net/ and confirm the tower(s) that are used as the PCI, physical cell ID can be determined and checked agains what the router reports. In my testing early on with this router I made incorrect assumptions and burned way too much time before I used cellmpapper to have 100% verification. I had a call with T-Mobile support they told me the tower coordinates, of the tower, and I confirmed it all using cellmapper.net to be clear about both the 4G and 5G NR connections. With that information you can know the radios that are present on the towers and see the 4G LTE cell identifications. Since the radios are not commonly omnidirectional it provides more clues as to what cell is sending in the location where you are. It takes a bit of time to pick it apart but is well worth the effort. Use that information and the reporting from the Nokia router to have the facts. One suggestion was made to use Opensignal to locate the tower but it does NOT provide sufficient detail nor does the app differentiate between carrier. It also does not currently support 5G NR signaling. Cómo usar www.cellmapper.net with a local computer takes a little to get used to but is muy informative. When I open the web page it has me in the Atlantic ocean off the coast of Africa. If everything is blue zoom out till you can see where you are on the map. Then orient yourself to where you need to be and dial it in. You would find using the T-Mobile USA - 310260 with a 5G tower search to start is less cluttered than using 4G LTE towers as a beginning. There are fewer 5G NR towers reported so it is not as cluttered and you can better see the details of the map. Going from one to the other is a simple and quick selection. In 5-10 minutes you will clearly know what T-Mobile towers are around you and be able to identify the one(s) that you connect to via the PCI reported. The cell phone and router may or may not latch onto the same tower. An iPhone in field test mode will identify the PCI just as the router identifies the PCI for each signal. Start with confirmation of the actual tower the router links to. If you have speeds over 100 Mbs down then your RSRP and RSRQ and SNR values should be decent. 

Yes rotation even very little can make a big diff.

I have not found an online source of tower data that is really even 75% up to date. At least in my area half of the towers are not even in the correct lat long. The 5G is almost not at all up to date as to which tower has what. I read that many towers and building are lower so they don't have to register the details with the FCC. Anyways I will have some more time to play in a few days had to do some pay the bills work lately.

But past few days I have not moved my can and speeds vary wide from 1 to 150 various times of the day. When I check the can signal always the same so seems to be congestion.

I do love all the in depth details you are going into I think it helps.
