MLB Blackout location problems 68U

Hi,

I have a T-Mobile converted 68U. When I am connecting with an Apple TV or Roku to it wirelessly (or wired) I can not watch some MLB games because it says I am blacked out. If I connect directly to the modem I am not blacked out.

Is there something in the router I am missing that would cause a location change? I have rebuilt the modem from scratch using Merlin and stock ASUS and same problem.

Thanks.
