Consistent disconnects and low speeds
Lately, I've noticed my connection dropping every few minutes for a couple seconds, just enough to disrupt anything that requires stable connection. On top of that, my speeds have gone down to 10-20 down and 30 up, (unless I'm talking to support, then they're miraculously 100+ both ways 🙄 (that's a whole other conspiracy))
Support is claiming work on the tower, which is a possibility I suppose. Upon digging deeper into it though, I figured out which tower I'm connected to via CGI info, and it's literally the one in my backyard, 300 yards away. Now, I can see that tower from my desk, and there has not been any work there for months now. The driveway leading to it has a huge tree down across is. So unless it's remote updates, I don't think there's been work to it. Even more baffling, is that this tower, according to Cellmapper, doesn't even cover my home, it's apparently pointed the opposite direction. The tower that best covers me is 1.7 miles away.
Advanced metrics reads as follows. Unfortunately, I never checked this info when times were good to compare it to now. The two that are currently "Good" do convert to "Excellent" a lot of the time. The "Poor" SINR is very rarely above a 4, no matter where it is in my house, and then other stats drop down in quality anyway. I've tried moving it around, and this is about as good as it gets location wise. Tool in the app confirms it as well.

Anyone have any idea what’s going on?
I’m no RF engineer, but at least a couple of those stats are awful.is
At 300 yards (I’m literally similar distance -1200’)
RSRQ is similar (doors closed) -7dB/-10dB closed -6/-10 door open)
RSSI (-94 / --84 closed/open)
RSRP ( -102/=103, -84/-99 closed / open)
There’s either something wrong with your modem, the antenna on the tower, or something is that tower hard
If I hit n71, SINR for me will drop to between and 10. I suspect that's because there are other n71 nearby. n41 should be hard to push a poor SINR at 300 yards.
Do you have T-Mobile cell service ? See what values you get from it.
Even with weak values with slider closed, I still hit +400Mbps with ‘good’ metrics.
While you can get good results at 1.7 miles, that RSRP tells me its closer. 1.7 miles would be a macro with a clear line of site, and antenna pointed at you. It is 'possible' on NSA to have 5g on a different tower than LTE, but the RSRP/RSRQ are quite similar and great values.
With cellmapper and NSA mode, you can see the ‘distance’ through timing advance on LTE.
