Live sports not loading

I have hard wired the house to try and stop the constant buffering issue but now it doesn’t load the channels with live sports playing. I click play now and it shows buffering then goes back to the play now screen. it will show other channels just not the ones with live sports. Very frustrating. Sometimes restarting the tablo works but why do i need to do that every time I want to watch a sporting event?

  1. What playback device?
  2. What is the make and model of your router?
