T-mobile 5g home internet forcing to tower with no data issues/changing towers/bands

ah well i tried to unplug the 5g router for 10 mins again and see if it would connect back to the b66 n71 tower but it did not so i guess that i cant reproduce that so maybe overheating isnt the issue. 

this is the usual speedtest from this tower 

DOWNLOAD TEST ERROR

A socket error occurred during the download test. A firewall could be blocking the connection or the server might be having some issues. Please try again later. also the ping was 1468 before this message came up.

Im actually pretty into computers and def would not be willing to let anyone else do anything to my computer also these problems occur on multiple pc and cell phones and xbox smart tvs. 

i even have a computer i just built with a brand new install of windows and new parts get the same problems.

i also have done all the cmd prompt ip and dns configurations and resets and renewing/registering dns and ip basically every internet configuration thing i could possibly think to do ive done now im not a pro and consider myself to be mediocre at pc related stuff but yea idk ive been building pcs for a long time now and typically troubleshoot/fix family and friends pcs pretty regularly. to me its a problem between the router and the tower or some settings t-mobile only has access to. 

also i regularly take my pc to freinds/family for gaming and or to update games because the internet is to slow to download 100 gb in any sort of timely manner and i have no problems using other peoples internet connections.

i mostly use visible cell phones mobile hotspot for all my internet when im at home and have normal consistent internet its just capped at 5mbps for hotspot while i normally dont even get 5mbps its basically always 2-5 mbps or more and has always worked for general internet/video around 720p sometimes during peak times only 480p but this is also stated that its capped at 5mbps so i dont have the same expectations from a plan thats only offering 5mbps. im pretty sure t-mobile says that it shouldnt be less than 25mbps and that most people are getting 100 mbps or more. 

anyways i got this device through a chat box so i find it kind of off that they dont have chat support for it. and this should be a very simple plug and play thing to setup so yea idk if someone really needs to come out to do something to make this device work than they shouldnt be offering it to people and clearly it works really well for some so i just have to think its a local tower issue or the 5g router device is faulty.

i am going to get in contact with t-mobile sometime in the next week or 2 just have other stuff i have planned already and its kind of idk not really a huge priority as im already going to be billed again in a week so im stuck with it at least another 5 weeks in my mind maybe ill make it into town at some point and goto the t-mobile store maybe i can just exchange my router for a new one.

although i really feel like general t-mobile employees are not going to really help much i do think i need to at the very least get in touch with someone in the next week or 2 for one last effort and  if its not working or some kind of news of towers being worked on after that i will just have to settle with 5mbps visibles  cellphone as a hotspot.
