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

If you have an Apple iPhone put it into "field test mode" and see where it connects. To get into field test mode on the iPhone turn off WIFI on it and then dial/call: *3001#12345#* From field test mode you can find the cell identifier possibly. I am just outside of Tusculum TN so I had a pretty solid idea of the tower the router connects to. Today I ran field test mode on my iPhone 12 and found the cell identifier that the phone radio connects to. I can see on cellmapper.net the cell identifier and confirm that is the tower. The only odd element here was I found the cell identifier and it was tagged as 5G which the phone also reported to being connected with. In cellmapper I found that by selecting the 4G LTE NOT 5G. The information on cellmapper is not updated. I joined the T-Mobile home internet BETA back in January so the fact that the information about that tower is not updated on cellmapper does not surprise me too much. I am highly confident that the tower IS indeed the one the router connects to as it was confirmed with the coordinates via a conversation with a T-Mobile support engineer. If people would just be kind to the support engineers they would find they receive mutual respect. I went out of my way to maintain a level tone and tried to be helpful with them and it got results. It bothers and boggles me that people tend to seem to think putting lots of negative trash on the forums will get positive results.
