Tmobile Home Internet with Tmobile Cellspot

¡Hola,

so two days ago I received my tmobile home internet gateway router and it works great with one issue I have not been able to overcome which is I also have the cellspot for expanding coverage in my house as there is hardly any to no signal within the house to use our phones. We have wifi calling and everything enabled and it just didn't work at all, but the cellspot worked great. The issue is the cellspot transmits a tmobile radio signal and my home internet wants to connect to the cellspot because it is the strongest signal it can pick up and obviously that wont work because the cellspot is connected to the home internet gateway router. So is there a way to blacklist or block the home gateway router from using the cellspot signal and to connect to the cell towers instead? With the cellspot off the home internet gateway router works great with awesome speeds, as soon as I plug in the cellspot I get nothing.

Any help would be greatly appreciated
