Home internet becoming unreliable after few months

The exact same thing has been happening to my 5G connection as mentioned by Marcia_1986. it worked ok for the first month with 300 down and 15+ up but not consistent though. En el second month, the signal has been dropping so often interrupting my Zoom conferences and other work. So my happiness with 5G internet lasted for one month and has been very disappointing after that. If T-Mobile doesn't get this corrected, I may have to check with other providers.
