TMobile Home Internet -- Great signal but no internet?

I've had a similar experience to what everyone here has been sharing. I went from a very reliable LTE upgrade to the 5G can. A few months ago I called in with this exact problem of the Internet randomly disconnecting. Interestingly, if you go onto the app it says that the Internet is connected. However, there is no actual Internet.  After doing the resets like everyone else for a few weeks,  I called service. They exchanged the can because they said that there was an hardware issue that could not be resolved with software. I was exceedingly hopeful.

Everything worked well for a few weeks and then the problem started coming back. This time I called right away and after getting through the first representative, I was directed to a higher level of technical support. The second level was not able to figure out what the problem was, and said that he would take this to some other engineers and that he would call me back with a status or resolution. A couple days later I got the call. The tech said that he was embarrassed to make this call because after speaking with the engineers, this is apparently a known issue. What was embarrassing for him was that they informed him there is no resolution, nor is there any plan to fix it. Obviously I was dumbfounded. It seemed as he was as well. He indicated that this is not a call that he likes to make, and is embarrassed to have to say it, but that was the case. 
 

So I'm not sure what to do now.  It seems as if T-Mobile has upset the industry enough to at least get Comcast Xfinity to do some really aggressive pricing. At my address they are offering 400 Mb for $30 a month. That's cheaper than the T-Mobile service but I don't know how much they're going to add and all those taxes and fees that got me running away from them in the first place. 
 

So frustrating!! I really liked being untethered and I still can't believe that T-Mobile is just letting this sit there.  Anyway, I thought I'd share my experience in case anyone who has his frustrated as me doesn't make it through three levels of technical support to find an answer. Good luck all.
