MLB The Show does not work on my T-mobile 5g internet box.

MLB the show is now working on my Xbox series S with T-Mobile home Internet. I switched the multiplayer connection from one position to another until it worked. It will work for a few weeks then I have to reset the router sometimes several times but it will start working again. I'm saving $80 a month from my old provider so I'm willing to live with resetting my router every few weeks.
