Why is it my 5G Internet Gateway can't work using 5G?

As I understand the connections for bands, a B connection is 4G (LTE) and the N connection would be 5G.  Whether bands using B12, B2 or B66 that primary signal is a 4G signal, right? Also, from the instructions (y T-mobile website) that primary connection ‘must’ be 4G (LTE) and only the secundario connection is 5G. 

As is in my case, where you get no secondary connection, you are not receiving 5G. Y punto.

And where (again as I understand the product correctly) secondary is not primary - you are using that primary 4G signal as your main connection – the gateway will no be providing you with 5G nor 5G speeds. Hmm.

Makes sense really, as the 600mHz signal only travels about 1,500 feet on average (three football fields) and low-lying trees and buildings can easily block the signal.

Heck, the closest 4G tower is less than ½ mile away, and I can barely keep the Gateway connected. Again, 2 -digits in their teens at best. At 4G.

The most disappointing aspect of this service has been the repeated calls to T-Mobile. Over a period of three months, I have logged upwards of 20+ hours in calls, looking for a resolution.  I have received repeated promises, am told that 'engineers will be contacted', and 'service will be restored’ (?), but to no avail.

Q: Was there ever any 5G in the neighborhood to begin with?  I think not.

I think it’s one thing to speak to problems rolling out the service that may (as yet) work in the area over 4G, but it’s really insulting to have you speak to the availability of services in 5G where there are none.

Congrats to you T-Mobile – you finally jumped the shark.

PS: Props to call center Salem, OR- at least you are trying!
